Mengzhou, Henan Province: Smart Agriculture Broadens the Way to Increase Income

  Chen Xinfeng, the person in charge of the ecological park, and the staff are carrying out professional leaf splitting, flower thinning and fruit thinning on the elevated strawberries to ensure the quality after listing. This is the second year that he has cultivated strawberries without soil. Compared with the traditional cultivation of strawberries, this cultivation technology has a better planting environment and greatly improved the picking experience of tourists. 

  

Tourists pick and punch cards in the high-ridge strawberry greenhouse. 

  "Our main varieties are ice cream strawberries, chocolate strawberries and cream strawberries. The output of each greenhouse is about 4,000 kilograms, and each kilogram can be sold to 45 yuan. From now until June, it is the peak season for picking, and the total income is expected to reach 300,000 yuan." Chen Xinfeng told reporters that the strawberries he planted were well received by the market. In addition to supplying local supermarkets, many customers in Zhengzhou and Luoyang booked them, which was in short supply. 

The person in charge introduced the situation of soilless cultivation of strawberries for tourists who came to pick them. 

  Inspired by "elevated" strawberries, in 2024, Chen Xinfeng transformed the strawberry greenhouse into a smart agricultural greenhouse to plant "high-ridge" strawberries to improve quality and yield. In the transformation, he raised the ridge by 30 cm with steel frame, which is more suitable for the development of sightseeing and picking agriculture; Adopt intelligent drip irrigation and water circulation heating technology system to accurately control air humidity and nutrient supply, and ensure stable growth environment while saving water and fertilizer; Using physical pest control and biological control technology to replace traditional pesticides to ensure that strawberries are green and pollution-free; Equipped with automatic temperature control and light supplement equipment, so that strawberry growth is not limited by natural conditions; Pure water irrigation is used to provide high-quality and stable water source for strawberry growth and accurately meet water demand. At the same time, he also introduced the drone pollination technology of "low temperature tolerance, no flight and no shed collision", which not only improved the fruit setting rate of strawberries, but also improved the fruit quality, making the fruit shape correct and the taste sweet. 

  Walking into the meat rabbit breeding base in Hanxi Village, Dading Street, rows of modern breeding cages are uniform, and fat meat rabbits are eating and drinking leisurely. The head of the base, Mao Xing, observed the growth of rabbits and carefully recorded them. "At present, there are 144 groups of modern breeding cages in our base, with a total of more than 3,400 meat rabbits, with an annual slaughter of more than 60,000, which can generate income of 500,000 yuan." Mao Xing happily talked to the reporter about the "rabbit breeding". 

Technicians check the growth of meat rabbits. 

  There are only three or four workers in the clean and tidy breeding shed, thanks to the automatic breeding equipment introduced by the base. Automatic temperature control technology can adjust the temperature of the breeding shed in time, which is more suitable for the growth of meat rabbits; Set the feeding time on the computer, automatically start the feeding function at the point of arrival, and automatically cut off the power after feeding, feeding 1-6 times a day, which better caters to the physiological characteristics of rabbits with less food and more meals; The automatic excrement cleaning system can automatically clean excrement, reduce ammonia smell and flies and mosquitoes, reduce the disease probability and mortality of meat rabbits, and improve the survival rate of young rabbits. In addition, the rabbit manure is also used as agricultural fertilizer and exported to Fujian and Shaanxi, which increases the economic benefits. 

  "This meat rabbit breeding project can also increase the income of the village collective by 100,000 yuan every year. In the next step, the two village committees will encourage interested people to learn rabbit breeding technology, so that meat rabbit breeding will become a characteristic industry in the village and a project to increase people’s income." Yao Jialian, secretary of the village party branch, introduced. 

  The industry is prosperous, the countryside is strong and the villagers are rich. In recent years, mengzhou city has continuously intensified the adjustment of agricultural industrial structure. By increasing the popularization and application of intelligent agricultural technologies such as drones, Internet of Things and big data in agricultural production, it has changed the extensive production management mode of traditional agriculture, improved agricultural production efficiency, improved the output and quality of agricultural products, and promoted the sustainable development of agriculture. 

  It is reported that in the next step, mengzhou city will promote agricultural modernization and intelligence by cultivating high-quality agricultural skilled talents in the new era, accelerating the application of smart agricultural technology, strengthening the guarantee of data elements, and strengthening the construction of talent teams, empowering the masses with smart agriculture, helping the rural areas to fully revitalize, and painting a new picture of a beautiful countryside with strong agriculture, beautiful countryside and rich farmers.

How did it become a "stem" for the whole network to flood with X-famous sentences posted by my brother?

       Only by reading this sentence, other friends must be very clear — — I’ve lost everything in this battle of pretending to be X. And this brother who posted it was nicknamed "Red Wall Brother" and "Terran Emperor" by others.

       In order to cooperate with the ridicule of other bar friends, Brother Red Wall himself has posted many times. It seems that he is "one-sided" but actually ridicules his response, which is a good show for many musicians.

Ranger 7

       It is also the incomparable classic reply of Brother Red Wall, which gradually spread from the post bar and even spread to every corner of the Internet. Even when I was watching League of Legends World Series, I couldn’t escape the attack of the red wall sentence.

       Just when RNG was at T13: 0, a few bullets floated past, which made me feel a little sad at once.

Ranger. com 8

       It seems that in just one night, this reply has become the famous stem of a hot Internet — — But even if a stalk is interesting, it will naturally rot if you talk too much.

       Soon, some people said that they felt uncomfortable at the sight of this sentence, and there was quite a case of "Juezi allergy" recurring. Brother Red Wall himself even replied, saying that he really didn’t expect such a ridicule to become like this, but now his brother’s post account seems to have been cancelled — — The appearance of "Brother Red Wall" was quite abrupt, which made people somewhat caught off guard, and this departure was even more surprising.

       However, it is also the time when the classic reply of Brother Red Wall triggered the imitation of the whole network. This post about the competitive power of giant red fish seems to have been completely ruined. The following is full of imitators of Brother Red Wall and similar sentences.

       But some people have new inspiration after this. Since "Wang Feng is here" can have a typical example like Brother Red Wall, why can’t other brothers who post it show their strength under this power post?

       For example, just let the elder brother of the fishing bar wave the fishing rod a few times. According to the theorem of "the fisherman will always be in the air force" and "the fisherman will do everything except fishing", this red fish quickly evacuated in order not to be transferred.

       What’s more, I think that only some brothers need to show their XP system, so that the fish can turn around and escape.

       Although Brother Red Wall’s reply has been widely circulated in just a few days, it has great potential to become the next "rotten stalk of the whole network", but some friends’ speeches are quite pertinent.

       After all, nowadays, when we talk about post bars, we will think of many sentence patterns full of rage and aggression. This sentence from Brother Red Wall is not only quite mild, but also just a joke with no practical significance.

       Of course, this red fish post can get widespread attention in "Wang Feng is in the bar", and even set off a discussion upsurge of the whole post bar, mainly because of the traditional culture of this post bar.

       Just listen to the name, I think many people will pop up many question marks: Wang Feng? Is Wang Feng here? This is a fan of singer Wang Feng, right? Why do you discuss these strange contents?

       But in fact, this post has nothing to do with Wang Feng himself. The reason why it has such a name is only because the original bar owners ID was "Wang Feng is here". The traditional culture of the whole post bar is: cross-border combat power competition regardless of region.

       For example, this ladder map of combat power, which is the most widely circulated in Wangba, can fully reflect the hobbies of these old friends, although it has different expressions with the "version update" and the selfishness of some bar friends.

Gold or gold? The gold price must prove that "the annual increase of 1.7% still exists" and the long-term fundamental supply and demand are challenged.

  Whether the safe-haven value of gold still exists or not has become a hot topic of concern to many market investors. From a fundamental point of view, the price of gold must prove that the annual increase of 1.7% still exists, but the long-term fundamental supply and demand are being questioned and challenged.

  Chimp Investor columnist Peter Elston mentioned that he considered what he could learn from the long-term price trend of gold, the so-called technicality. The final conclusion is that although the inflation-adjusted return of gold may still be poor in absolute value in the short term, it may still be better than that of stocks, bonds and cash, especially if the inflation rate remains high in the next few years.

  He also suggested that in the past 50 years, the inflation-adjusted annual appreciation trend of gold price should remain unchanged at 1.7%, because the growth rate of global real wealth may continue to exceed this value. However, this is too simplistic and assumes that the fundamental reason for buying gold will not change much, which should be challenged.

  This article focuses on the root cause of gold’s popularity, its supply dynamics, and its fundamentals, to see if they still prove that the above historical trend, the actual price increase of 1.7% per year still exists.

  Gold is an iron-loving element, which means that it is heavy, easy to dissolve in iron, and doesn’t like to combine with oxygen. The oxide of gold is actually thermodynamically unstable. Therefore, its concentration is higher in the deep core and mantle than in the crust. Compared with the very low occurrence rate of the whole crust, the exploitable gold deposits are even rarer. In addition, the mineable deposits have now been exhausted, so that the annual output of gold has been flat since 2016. In the absence of major changes in mining technology and/or a drop in energy prices, this slowdown in annual output may continue.

  The chemical inertness of gold makes it very suitable for jewelry, electronic products, dentistry, aerospace and value storage as gold bars and coins. The World Gold Council estimates that by the end of 2021, 205,238 tons of gold have been discovered/mined in the past 6,000 years, and the proven unexploited reserves total 53,000 tons, the latter figure is lower than 54,000 tons in 2019. It is also estimated that there are 15,000 tons of gold dissolved in the world’s oceans, equivalent to about 10 parts per trillion.

  It is the inertia and rarity of gold that endows it with intrinsic value, that is, its practicality and practicality. Warren Buffett once wrote a famous saying that gold is dug out of the ground in Africa or somewhere, and then we melt it, dig a hole, bury it, and then pay people to stand around and guard it. It is not practical, and anyone who watches it from Mars will be puzzled.

  But Elston doubts that Buffett will shine in the short term, but he will surely see that many people have done so for thousands of years and will almost certainly continue to do so. Besides, if he has a mobile phone or a tooth filling, he may benefit from the utility of gold to a greater extent than he is willing to mention.

  As for the use breakdown of 205,238 tons of above-ground inventory, jewelry accounts for 46%, privately owned gold bars, coins and ETFs account for 22%, the central bank accounts for 17%, and other uses such as electronics, dentistry and aerospace account for 15%. It is estimated that as much as 80% of the newly mined or recycled gold is used for jewelry manufacturing.

  Looking forward to the future of gold, it needs to be clear that Elston is not interested in the factors that may affect the short-term price performance of gold. They are essentially emotional-driven and unpredictable. In addition, compared with the long-term possible percentage change, the short-term performance is insignificant.

  In other words, the really important factors are those related to basic supply and demand. They will determine the long-term performance of inflation-adjusted gold prices. For example, whether it will increase by 300% or decrease by 75% in the next decade. In his view, this is exactly what the market should pay attention to, not whether the nominal price of the US dollar will fall below $1,500 in the next few weeks.

  As mentioned above, the annual gold production has been declining and has been flat since 2016. Environmental problems limit the potential of new discoveries. The progress of mining technology is related to the use of unmanned aerial vehicles, virtual reality, self-driving cars and blasting optimization. They didn’t, in fact, solve the basic law in a meaningful way, that is, the deeper you want to dig, the more energy you need.

  Although 75% of the annual gold demand is met by mining gold supply, the shortage is made up by recycling, mainly jewelry. In the short term, the supply of recycled gold is sensitive to the price of gold. In addition, the dynamics behind the basic supply of recycled gold are unlikely to change significantly.

  About 6000 years ago, the first known use of gold was as decorative beads. It is hard to see how this established popularity will fundamentally change. According to the data of the World Bank, since 1971, the real GDP of the world has increased by 3.1% every year, while the appreciation trend of the real gold price in the same period is 1.7% every year. Generally speaking, in the past 50 years, the world’s real GDP has increased by 360%, which is 130% higher than the real gold price. In other words, the rise of gold prices in the past 50 years has been supported, proved and explained by the growth of global wealth.

  In recent years, the net purchase of gold by central banks has been quite stable, with an average of about 500 tons per year. The use of gold, whether as jewelry or as a means of value storage, is inseparable from its chemical characteristics. Therefore, it seems unlikely that central banks will lose interest in holding physical gold in their vaults in the near future or even the distant future. Net purchases may vary from quarter to quarter, sometimes very different, but the long-term trend seems to have been established.

  The demand for private investment in gold is probably the most interesting of the four main sources. Its utility as a private value store is similar to that of the central bank, that is, it is related to its chemical properties. However, economies of scale make it expensive and/or risky for private individuals to store gold at home, so most people hold gold in paper form, that is, certificates and ETFs. Proponents of cryptocurrency have seized this obvious inefficiency, claiming that things like bitcoin should be regarded as digital gold, thus invalidating the current utility of gold as a private sector value store.

  The use of gold as jewelry and storage of private and public values is inseparable from its chemical characteristics, in other words, the demand for gold bars goes hand in hand with the demand for jewelry. Bitcoin and other cryptocurrencies don’t have such basic attributes, and they never will. A USB flash drive storing encrypted access codes is unlikely to be worn as jewelry. Unless, of course, they are made of gold.

  Elston said that the most interesting reason for the demand for private investment is that in difficult economic times, gold may be sold to buy more necessities, thus putting downward pressure on prices. However, in the severe economic difficulties, due to high inflation, people lose confidence in legal paper money, and the demand for it as a means of value storage will increase.

  He is not sure whether he wants to live in a world where gold has replaced paper money as the main currency, but this does not mean that economic difficulties will continue but increase gradually in the long run. For example, global temperature rise, war, famine and epidemic diseases will not lead to the appreciation of gold prices.

  Describe the various ways of gold, namely, value storage, inflation hedging, safe haven and investment. As should be clear, value storage is something that actually keeps its value. Gold has always been a means of value storage, and its inflation-adjusted price has shown an upward trend in the past 50 years. However, if you bought gold in 1981, you are actually still underwater. In other words, the actual decline of gold may exist and has existed for a specific period of several decades.

  The reputation of gold as an inflation hedge tool was established in 1970s, 1980s and 1990s, but the relationship has not been obvious since then. It is true that in naughty times, when inflation fell, the real price of gold rose by more than 400%. Therefore, Elston is not sure whether the argument that gold is an inflation hedging tool is valid, except in severe economic difficulties, such as the use of hyperinflation in Germany.

  Is gold a safe haven, that is, defensive? In other words, when risky assets such as stocks and high-yield bonds perform poorly, does it perform well? Similarly, there is no real evidence that this is indeed the case. It has not performed well this year, which is a period of poor performance of risky assets.

  Finally, Elston never considered physical gold as an investment. This is because physical gold is different from stocks, bonds or property, and the former does not actually generate income. It is more similar to cash, and the portfolio allocation of physical gold should be regarded as a cash substitute. He finally stressed that this does not mean that high cash distribution is appropriate, and gold should be more popular as cash than legal tender.

Fight the tough battle of agricultural non-point source pollution prevention and promote the sustainable development of agriculture

  At present, China’s agricultural and rural economic development has entered the best historical period, and grain production has achieved "11 consecutive increases", which has been stable at more than 1.2 trillion Jin for two consecutive years. At the same time, it has made great achievements and paid a huge price. The string of resource utilization is getting tighter and tighter, and the carrying capacity of the ecological environment is getting closer and closer to the limit. Facing the double "curse" of resource conditions and ecological environment, it is urgent to change the mode of agricultural development, strengthen the control of agricultural non-point source pollution, effectively promote the protection and control of agricultural ecological environment and promote the sustainable development of agriculture.

  First, scientific graspAgricultural non-point source pollution situation, and effectively enhance the sense of urgency and responsibility of agricultural non-point source pollution prevention and control work.

  The first national pollution survey showed that in 2007, the chemical oxygen demand (COD), total nitrogen and total phosphorus emissions from agricultural sources in China reached 13.2 million tons, 2.7 million tons and 280,000 tons respectively, accounting for 43.7%, 57.2% and 67.4% of the total national emissions respectively. Among them, livestock and poultry breeding sources account for 96% of agricultural source COD, and are the main "contributors" of agricultural non-point source pollution. Agricultural chemicals such as livestock and poultry, aquaculture, chemical fertilizers, pesticides and agricultural films are the main sources of pollution. Different from industrial point source pollution directly entering the water body through centralized sewage outlets, agricultural non-point source is decentralized, and its pollution process is not a simple direct causal relationship from agricultural production behavior to discharge, and finally to environmental impact. The research shows that 35% of nitrogen in farmland chemical fertilizer in China is utilized by crops in the current season, and most of the rest is retained in farmland soil, and a small amount flows into ditches, and finally less than 5% enters the surface water body through runoff. Therefore, although the total amount of agricultural source pollutants discharged in China is relatively high, the amount that actually enters the water body is still very limited.

  At present, the situation of agricultural non-point source pollution is generally grim, but there are also some particularities, which require us to make careful judgments and make precise policies.

  First, the intensive degree of aquaculture is getting higher and higher. Due to the low resource utilization rate of livestock manure and other wastes, pollution emissions are on the rise.In recent years, the total amount of livestock and poultry breeding in China has been increasing. In 2013, the number of live pigs slaughtered in China exceeded 700 million. At the same time, the scale and intensification have developed rapidly, and the proportion of large-scale breeding of more than 500 pigs per year has reached 40.8%. At the same time, the construction of livestock waste treatment facilities is relatively backward, and a large amount of livestock manure is difficult to be treated and utilized in time, which makes livestock waste change from traditional farmyard manure to pollutants. In addition, the scale of aquaculture in China is also expanding rapidly. In 1978, the total amount of aquatic products was 4.654 million tons, of which artificial aquaculture accounted for 26.1%. In 2013, the total amount of aquatic products reached 61.72 million tons, accounting for 73.6%. A large number of bait and fish medicine were put into aquaculture, which caused water pollution.

  Second, the amount of chemical fertilizer used in the main grain crops is basically reasonable, and the phenomenon of excessive application of economic crops such as vegetables and melons is more prominent. On the whole, the growth rate of chemical fertilizer consumption is declining, but the amount of chemical fertilizer input is still too large.In 2013, the amount of chemical fertilizer used in China was 59.12 million tons, accounting for 35% of the world. Based on 2.03 billion mu of cultivated land, the average amount of chemical fertilizer used per unit area reached 436.8 kg/ha, which was far higher than the world average. It is worth pointing out that at present, the average amount of nitrogen fertilizer used in China’s main grain crops is about 212 kg/ha, which is lower than the upper limit of environmental safety (the upper limit of safety set by developed countries for preventing water pollution is 225 kg/ha), but the average amount of nitrogen fertilizer used in fruit trees and vegetables is far higher than the environmental safety requirements, and the phenomenon of excessive application of chemical fertilizers in orchards and protected vegetables is still prominent.

  Third, the use of pesticides per unit area is higher than the world average, but lower than that of developed countries such as the United States. The overall usage tends to be stable, but the utilization rate is low.In recent years, the amount of pesticides used in China has stabilized at about 320,000 tons (active ingredients), accounting for 1/7 of the total amount of pesticides used in the world, which is higher than the proportion of China’s land area to the world’s cultivated land area, which is related to the high land multiple cropping index in China. Generally speaking, China’s pesticide consumption per unit area is higher than the world average, but lower than that of developed countries such as the United States, Israel and Japan. On the other hand, at present, the utilization rate of pesticides in China is low, only 35%. Residual pesticides enter water bodies through precipitation, surface runoff and soil infiltration, which will lead to the deterioration of soil and water environment quality, destroy ecology and affect biodiversity.

  Fourth, the recovery rate of plastic film is low, and the problem of residual old agricultural film still needs to be solved.China’s total use of plastic film and crop coverage area rank first in the world. In 2013, the consumption of agricultural film in China was 2.493 million tons. Due to the extensive use of ultra-thin plastic film and the lack of recycling technology and mechanism of residual film, the "white revolution" gradually evolved into "white pollution", and the problem of residual pollution of farmland plastic film became increasingly prominent. Plastic film residue is serious, affecting soil structure and reducing cultivated land quality; Affect the emergence of seedlings, resulting in reduced production; Affect the operation of agricultural machinery, resulting in a decline in the quality of sowing and fertilization; Livestock eating by mistake occurs constantly, which is harmful to livestock health.

  Fifth, the comprehensive utilization rate of crop straw is low, and the recycling capacity needs to be improved urgently.Crop straw is a versatile agricultural resource. It is estimated that in 2013, the total output and collectable amount of straw in China were 964 million tons and 819 million tons, respectively. The actual utilization amount was about 622 million tons, and the comprehensive utilization rate was only 76%. With the change of agricultural energy structure, the proportion of crop straw in domestic energy is less and less. The way out for excess straw is: firstly, burning on the spot will cause air pollution, reduce atmospheric visibility, hinder traffic and endanger human health; Second, abandoned fields or piled into rivers or lakes, after weathering, rain and decay, the organic matter in straw enters the water body and causes pollution.

  Generally speaking, with the continuous improvement of agricultural intensification and the rapid development of aquaculture in China, the problem of agricultural non-point source pollution caused by excessive use of agricultural inputs such as chemical fertilizers and pesticides and unreasonable disposal of agricultural wastes such as livestock manure, crop straws and farmland plastic film residue has become increasingly prominent, which seriously restricts the sustainable development of agriculture and rural economy. Therefore, strengthening the control of agricultural non-point source pollution is a realistic need to ensure the safety of agricultural products, realize China’s food security and quality safety of agricultural products, and is an internal need to improve the agricultural ecological environment, accelerate the transformation of agricultural development mode and realize the sustainable development of agriculture. We must scientifically grasp the increasingly serious situation of agricultural non-point source pollution, deeply understand the great significance of strengthening the control of agricultural non-point source pollution, and earnestly enhance the sense of urgency and responsibility in our work.

  Two, the agricultural ecological environment protection and governance work has made positive progress, laying a solid foundation for the prevention and control of agricultural non-point source pollution.

  Agricultural non-point source pollution in China is a long-term accumulation, which has its particularity and complexity. It can’t be completely solved overnight, and it needs a long period of unremitting efforts. In recent years, while ensuring the development of agriculture, agricultural departments at all levels have continuously increased the protection and governance of agricultural ecological environment, initially established a team of agricultural non-point source pollution prevention and control and expert support teams, and gradually established and improved the policy system, exploring and forming a number of practical technologies and typical models, which have laid a good foundation for the fight against agricultural non-point source pollution.

  First, the construction of the system team has been continuously strengthened.A four-level agricultural environmental protection management system has been formed, with two state-level main stations as the leader, 33 agricultural environmental protection stations in provinces, autonomous regions, municipalities directly under the Central Government and cities under separate state planning as the main body, and 326 prefecture-level stations and 1794 county-level stations as the basis, which provides a team system guarantee for agricultural ecological environment monitoring and prevention and control.

  Second, the monitoring and early warning capabilities have been continuously improved.A national agricultural non-point source pollution monitoring network has been initially established, and the normal and institutionalized operation of agricultural non-point source pollution monitoring has been continuously promoted; A four-level cultivated land quality monitoring network at the national, provincial, municipal and county levels has been established, and an annual report on national cultivated land quality monitoring has been issued; An environmental monitoring network system covering China’s offshore bays, islands and reefs, beaches, nature reserves, aquatic germplasm conservation zone and aquaculture waters has been initially formed, and the Bulletin on Fishery Ecological Environment in China has been issued regularly. A national monitoring network for pollution of agricultural products was established to carry out heavy metal pollution investigation in the producing areas.

  Third, vigorously promote the scientific application of chemical fertilizers and pesticides.Comprehensively popularize the technology of soil testing and formula fertilization, with the promotion area reaching 1.4 billion mu; In-depth implementation of green prevention and control, the establishment of 150 national green prevention and control demonstration zones, the gradual elimination of 33 kinds of highly toxic pesticides, and vigorously promote the use of high-efficiency, low-toxicity, low-residue and biological pesticides; Carry out the integration of specialized unified prevention and control of crop pests and diseases with green prevention and control, promote pilot construction, and establish 218 demonstration bases; At the beginning of 2015, the Action Plan for Zero Growth of Fertilizer and Pesticide Use by 2020 was issued, and the zero growth of fertilizer and pesticide use was initiated.

  Fourth, actively promote pollution prevention and control of livestock and poultry breeding.Accelerate the standardization of livestock and poultry breeding, create 3,397 standardized demonstration sites, and effectively improve the level of pollution prevention and control of livestock and poultry breeding; Start the pilot project of comprehensive utilization of livestock and poultry waste; Develop rural biogas projects according to local conditions and improve the sewage treatment capacity of rural farming manure.

  The fifth is to carry out comprehensive utilization of straw in depth.Implement the comprehensive utilization project of straw, focusing on supporting Beijing-Tianjin-Hebei and other areas to carry out straw returning to the field, raising livestock, straw biogas, straw replacing wood, straw carbonization and other work; We will start the construction of a demonstration area for full quantitative utilization of straw at the township level in Beijing, Tianjin and Hebei, and accelerate the scale and industrialization of straw utilization.

  Sixth, efforts should be made to solve the pollution of farmland residual film.Revise the standard of plastic film to solve the problem that residual film is easy to break and difficult to recycle; For four consecutive years, the agricultural cleaner production demonstration project focusing on the recycling of waste plastic film was implemented, and the plastic film recycling and processing system was initially established; Arrange subsidies for dry farming technology such as plastic film mulching in northwest and north China to promote the popularization and application of high-standard plastic film; The comparative test of degradable plastic film was started, and the degradable plastic film with good application effect was screened for demonstration and popularization.

  Seventh, work together to promote the demonstration construction of comprehensive management of agricultural environment.A typical driving system of modern eco-circular agriculture has been formed, which consists of 1 eco-circular agricultural pilot province, 10 circular agricultural demonstration cities, 283 national modern agricultural demonstration zones, 1,100 beautiful countryside and several eco-agricultural demonstration bases. In key river basins and important water source protection areas, we will implement the construction of demonstration zones for the comprehensive prevention and control of livestock and poultry breeding wastes and agricultural nitrogen and phosphorus pollution, and actively explore effective mechanisms for the prevention and control of agricultural non-point source pollution in river basins.

  To sum up, in recent years, the positive results of agricultural ecological environment protection and governance, as well as the continuous improvement of agricultural production and income and rural development, have made us more qualified, capable and confident to fight the tough battle of agricultural non-point source pollution prevention and control.

  Three, to "one control, two reduction and three basics" as the key task, to fight the battle against agricultural non-point source pollution.

  Since the 18th National Congress of the Communist Party of China, General Secretary of the Supreme Leader and other central leading comrades have repeatedly made important instructions on the protection and governance of agricultural ecological environment. General Secretary of the Supreme Leader pointed out that agricultural development should not only put an end to the new debts owed by the ecological environment, but also gradually pay back the old debts, and fight a tough battle for agricultural non-point source pollution control. Premier Li Keqiang proposed that the deterioration of resources and environment should be resolutely suppressed and the overdrawn resources and environment should be rehabilitated. In order to implement a series of deployment requirements of the CPC Central Committee and the State Council, at the beginning of this year, the Ministry of Agriculture, together with relevant departments, successively issued the National Agricultural Sustainable Development Plan (2015-2030), the Agricultural Prominent Environmental Problems Control Plan (2015-2018) and the Implementation Opinions of the Ministry of Agriculture on Fighting the Fight against Agricultural Non-point Source Pollution. Recently, a national on-the-spot meeting on accelerating the transformation of agricultural development mode and a national conference on the protection and governance of agricultural ecological environment have been held in Sichuan, which is an important meeting with milestone significance in the development process of modern agriculture in China. The promulgation of these documents and the convening of the conference have fully deployed and mobilized the protection and governance of agricultural ecological environment. At present, the most important task is to focus on the goal of "one control, two reductions and three basics" and fight a tough battle against agricultural non-point source pollution.

  First, vigorously develop water-saving agriculture.Facing the severe situation of increasingly scarce water resources, it is necessary to increase efforts to develop water-saving agriculture. By strengthening the demonstration of water-saving agriculture, actively promoting water-saving varieties, integration of water and fertilizer, circulating aquaculture and other technologies, the utilization efficiency of water resources will be improved in an all-round way. Actively promote the comprehensive reform of agricultural water price. Coordinate the promotion of water ecological protection and management in river basins, and actively carry out the construction of demonstration zones for comprehensive prevention and control of agricultural non-point source pollution in key river basins such as Taihu Lake, Erhai Lake, Chaohu Lake and Three Gorges Reservoir Area. By 2020, the national agricultural irrigation water consumption will be controlled within 372 billion cubic meters, and the effective utilization coefficient of farmland irrigation water will reach 0.55.

  The second is to implement the zero growth action of chemical fertilizers.The key to reducing fertilizer application is to establish the concept of green yield increase, vigorously promote scientific fertilization, improve the accuracy and utilization rate of fertilizer use, and encourage farmers to use more green manure and farmyard manure. The key point is to expand the application scope of soil testing and formula fertilization, and promote the formula fertilizer to enter the village and enter the field. At the same time, it is necessary to actively promote the research and development and promotion of new fertilizer products, and integrate and promote high-efficiency fertilization technologies such as simultaneous sowing of seeds and fertilizers and deep application of fertilizers. It is necessary to combine the construction of high-standard farmland, vigorously carry out the action of protecting and improving the quality of cultivated land, study and use subsidies to encourage and guide farmers to promote straw returning, planting green manure, accumulating farmyard manure and increasing the application of organic manure, rationally adjust the fertilization structure, and strive to improve the internal quality of cultivated land. Strive to achieve more than 90% coverage of soil testing and formula fertilization technology, more than 40% utilization rate of chemical fertilizers, and zero growth in the use of chemical fertilizers for major crops in China by 2020.

  The third is to implement the zero growth action of pesticides.Adhere to comprehensive management, treat both the symptoms and the root causes, and realize scientific and accurate drug application. Strengthen the management of pesticide use, strengthen source management, and standardize farmers’ use of pesticides. Fully implement the fixed-point management of highly toxic pesticides and establish a traceability system for highly toxic pesticides. We will implement pilot projects for the use of low-toxic and low-residue pesticides, gradually expand the scope of subsidy projects, and accelerate the popularization and application of biological pesticides and high-efficiency, low-toxic and low-residue pesticides. Encourage agricultural socialized service organizations to provide guidance and services for farmers to use pesticides, and vigorously promote the integration of specialized unified prevention and control and green prevention and control. Ensure that by 2020, the coverage rate of green prevention and control of major crop pests and diseases will reach more than 30%, the utilization rate of pesticides will reach more than 40%, and the use of pesticides for major crops in China will achieve zero growth.

  The fourth is to promote the prevention and control of aquaculture pollution.Overall consideration of environmental carrying capacity and pollution prevention requirements of livestock and poultry breeding, scientific planning and layout of livestock and poultry breeding. Promote standardized scale farming, supporting the construction of treatment and utilization facilities, improve facility farming technology, improve technical and equipment conditions, and encourage and support the implementation of household collection and centralized treatment of livestock and poultry manure in densely populated areas. Strengthen the construction of demonstration farms for healthy aquaculture, and popularize aquaculture technologies such as industrialized circulating aquaculture, pond ecological circulating aquaculture and bottom sewage of large-surface cage aquaculture. By 2020, more than 75% of large-scale livestock and poultry farms (districts) will build supporting facilities for waste storage, treatment and utilization.

  Fifth, efforts should be made to solve the residual film pollution in farmland.Accelerate the revision of mulching film standards, strictly stipulate the thickness and tensile strength of mulching film, prohibit the production and use of substandard mulching film, and ensure that the residual mulching film in farmland can be recycled from the source. Increase financial support for technical subsidies for dry farming. Carry out regional demonstration of farmland residual film recycling, support the construction of plastic film recycling outlets and waste plastic film processing capacity, gradually improve the recycling network, and innovate the plastic film recycling and reuse mechanism. Accelerate the research and development of eco-friendly degradable plastic film and plastic film residue picking and processing machinery, and establish and improve the evaluation system of degradable plastic film. Ensure that by 2020, the recovery rate of agricultural film will reach more than 80% in the current season.

  Sixth, carry out in-depth utilization of straw resources.According to the idea of "policy support, demonstration and guidance, focusing on agriculture, industrial development and market operation", we will promote the full utilization of straw "five materials" according to local conditions. It is necessary to further support the demonstration of new technologies such as straw harvesting machinery returning to the field, green and yellow storage for feed, microbial decay and solidification carbonization gasification, and study and introduce policies and measures such as enjoying the price of agricultural electricity for straw primary processing, incorporating storage and storage land into agricultural land management and credit support. Accelerate the establishment of a market-oriented mechanism for straw storage and transportation, reduce the cost of storage and transportation, and promote the scale and industrialization of comprehensive utilization of straw. In the key areas of air pollution, start the construction of demonstration counties for comprehensive utilization of straw, and fundamentally solve the problem of open burning of straw. Achieve the goal that the comprehensive utilization rate of straw will reach over 85% by 2020.

  Agricultural non-point source pollution control is a tough battle and a protracted war. We need to base ourselves on the present and focus on the long-term. We should focus on five "enhancements" and five "enhancements", strengthen top-level design, increase planning and implementation, strengthen legal promotion, increase supervision and law enforcement, strengthen financial security, increase social participation, strengthen monitoring and early warning, increase scientific and technological support, strengthen policy creation, increase supervision and assessment, and take multiple measures to ensure implementation.

China CDC: It is recommended to vaccinate against influenza as soon as possible, especially for the elderly and children.

  CCTV News:The National Health and Wellness Commission held a press conference on December 2 to introduce the prevention and treatment of respiratory diseases in winter and answer media questions.

Xinhua News Agency: Vaccine has played a key role in the prevention and control of influenza. At present, influenza has entered the high season. Is it too late to vaccinate now?

Wang Dayan, Director of National Influenza Center, Institute of Virology, China CDC:Among the prevalent respiratory diseases, influenza, COVID-19 and pneumococcal infection all have corresponding types of vaccines. The influenza vaccine has been used in the world and China for decades. Scientific research and vaccination practice have fully proved that the influenza vaccine is safe, effective and a mature vaccine. Influenza vaccination can effectively reduce infection, even if it is infected, it can also reduce the incidence, and even if it is infected, it can also reduce the severity of the disease.

At present, it is the high season of influenza, and it is still effective to vaccinate people who have not been vaccinated with influenza before. It is recommended that you vaccinate with influenza as soon as possible. Here, I especially point out that people over 6 months can be vaccinated with influenza, especially for high-risk people such as children, the elderly and patients with chronic diseases. After being infected with influenza, the risk of severe illness is higher. Vaccination with influenza can effectively reduce the risk of developing into severe illness and death. I hope everyone will actively vaccinate.

Practice at home and abroad has proved that the use of vaccine is one of the most economical and effective preventive measures, and the vaccine is safe. As long as it is vaccinated in professional institutions as required, it can have good results, especially for the elderly and children, and should actively vaccinate against influenza to ensure the normal pace of life and study.

China Sichuan Cuisine Industry City: From "Garden" to "City", strengthen the chain, complement the chain and improve the supporting facilities

Past lives, who knows Sichuan cuisine, tastes the private cuisine of Sichuan cuisine masters, and experiences the leisure of rural life … A new landmark of online celebrity, Sichuan Life Aesthetics Museum, was born in China Sichuan Cuisine Industry City, the first industrial functional area named after local cuisines in China, and now there are an endless stream of visitors here every day.

The poetic and atmospheric Sichuan Life Aesthetics Museum is only a part of the first opening area of Sichuan cuisine town. This project with a total investment of more than 20 billion yuan will bring surging new kinetic energy to the development of China Sichuan cuisine industrial city. Why should China Sichuan Cuisine Industry City, which mainly produces Sichuan condiments and snack foods, lay out a Sichuan cuisine town project with an area of over 1,000 mu?

Zhao Dong, head of China Sichuan Cuisine Industry City Management Committee, said in an interview that the eighth meeting of Chengdu Industrial Functional Zone and Park Construction Leading Group held at the beginning of this month made it clear that the name of Chengdu Sichuan Cuisine Industry Park was optimized and adjusted to China Sichuan Cuisine Industry City, which gave the functional zone a new mission from "garden" to "city". Sichuan Cuisine Town, a project with composite functions, can just fill the gap in the lack of high-end industrial communities in traditional industrial parks, provide high-quality living space for senior talents in Sichuan Cuisine Industry and undertake the task of Sichuan Cuisine Industry City.

Get through the pain point

Leading enterprises have expanded their production scale.

Machines are roaring, scaffolding is everywhere, and workers are busy … Walking into China Sichuan Food Industry City, which is located in Ande Street, Pidu District, "Building a new factory and expanding production scale" is the most frequently heard words by reporters. The construction of new production bases of a number of leading enterprises such as Dandan, Tianwei and Dingdianer is in full swing.

"Last year, we rose against the trend and achieved an operating income of 1.393 billion yuan, a year-on-year increase of 69.89%." Last Friday, the reporter came to the management committee of China Sichuan Cuisine Industry City, where an intelligent factory training was being held. Dai Li, the administrative director of Tianwei Food, listened very carefully. She wrote down a few pages in her notebook. "At the right time, the key word of our second phase project is intelligence. The workshop covers an area of 30 mu, and there are no more than 80 workers in a single shift. The annual output value created will be the sum of the four workshops of the first phase project ABCD, compared with the first phase, which covers an area of 120 mu.

Coincidentally, as the earliest project in the park, the second phase of Dandan Douban Project will be completed and put into production in June this year. The project will have an annual output of 60,000 tons of Pixian watercress and fine Sichuan composite condiment, and the same intelligent factory will be used. "In China Sichuan Food Industry City, intelligent production has become a trend." Yang Wei, personnel and administrative manager of Dandan Pixian Douban Group, said that the vast space for the development of Sichuan condiment industry and the good service of the Sichuan Industrial City Management Committee have made enterprises full of confidence in the future development.

Last year, the municipal and district governments gave a number of service packages to many enterprises in the industrial city. Take Dandan Douban as an example, it has enjoyed more than 4 million yuan of policy support funds such as online training and employee on-the-job training, and also enjoyed more than 4 million yuan of social security relief.

"Especially in the key links of the industrial chain, the Sichuan Industrial City Management Committee and various departments in Pidu District have made great efforts to find out the pain points and protect the development and growth of the enterprise." Du Jinchuan, director of the laboratory of Dandan Douban Quality Control Department, said that taking Shenzhen Yingbai Testing Technology Co., Ltd., which was introduced and settled by Pidu New Science Bureau, as an example, the company dispatched experts from Beijing, Shanghai, Shenzhen and other places to stay in Sichuan Food Industry City and set up Yingbai Testing Chengdu Laboratory, so that many enterprises can enjoy professional testing services without leaving the industry city.

"A variety of testing items were sent to Longquanyi for testing before, and we had to wait in line for a week or two. After the first phase of Chengdu Yingbai testing with an investment of 25 million yuan was put into use in December last year, we no longer had to go back and forth." Du Jinchuan said that now it can be said that you can enjoy the "VIP service", and the testing time has been shortened from one or two weeks to one or two days. If there is any problem, you can communicate at any time on the phone and WeChat, and you can also deal with it in time in case of an accident.

Not only inspection and testing, but also through the mode of "Commissioner+Expert", the Management Committee of Sichuan Industrial City has built a normalized and accurate docking platform between enterprises and famous food colleges such as Jiangnan University to promote the flow and aggregation of innovative resources to industrial functional areas and solve the "stuck neck" problem of industrial development.

Layout innovation chain

Aiming at the common bottleneck of industry and strengthening technical cooperation

"From Chengdu Sichuan Cuisine Industrial Park to China Sichuan Cuisine Industrial City, from’ Garden’ to’ City’, the functional area has been endowed with new missions and higher requirements, which need a new height and a new perspective to understand and grasp." In Zhao Dong’s view, this contains changes in concept, function, connotation and energy level. "As an important carrier of industrial agglomeration, functional areas should not only give full play to their advantages to be the’ long board’ of long-term manufacturing functions, but also fill the’ short board’ of urban service functions, create more complex and comprehensive regional functions, update and improve more sophisticated and diversified industrial service packages, and devote themselves to forming’ three lives’ of life, ecology and production.

The town of Sichuan cuisine is a representative project with many complex functions. Taking "two axes, six hearts and six districts" as the overall planning, the project uses innovative means, integrates international resources, promotes the upgrading of the three industries, improves the two industries and promotes the upgrading of one industry, and builds an ideal living town in Sichuan and Sichuan, China, which integrates "cultural tourism, pastoral, leisure, health care, education, suitability for business and livability" around the two IP’s of "Sichuan cuisine culture" and "modern urban pastoral". "Peng Xuqing, a master of Sichuan cuisine who has more than 7.3 million fans in Tik Tok, has now settled in the Sichuan Life Aesthetics Museum. Our guests have tasted the’ master dishes’ made by him and are full of praise." The heads of several enterprises in Sichuan Cuisine Industrial City said with emotion that from "people who produce in the city" to "people who produce in the city", the Andeyuan District People’s Hospital, the comprehensive convenience center and the foreign language school, which have been upgraded to a third-class hospital, have settled in one after another, and the supporting facilities of the industrial city are becoming more and more perfect, and employees can meet the needs of production and life without leaving the functional area.

"Not only the’ Master Cuisine’, but also Shuxiang 183, which will be unveiled in the next step, is another core competitiveness of us. The most authentic and representative foods from 183 districts and counties in Sichuan will be presented here, and they will be eaten all over Sichuan in one day." The relevant person in charge of Sichuan cuisine town told the reporter that the Sichuan cuisine town project is dedicated to building a Sichuan cuisine exchange and promotion center and a Sichuan cuisine experience tourism destination with the theme of excavating Sichuan cuisine culture and new consumption scenes. According to calculations, it will attract 4 million tourists every year in the mature period. Come here to experience consumption.

The introduction of huge traffic will also promote the transformation and upgrading of Sichuan cuisine industry. Sichuan Town will also plan to build 221 mu of high-quality science and technology space of "Sichuan Cuisine Kechuangli", focusing on the layout of "one headquarters and three centers" (science and technology research and development headquarters, promotion and operation center, incubation and transformation center, comprehensive service center), introducing R&D design, innovation and transformation, scene creation, community service and other functions, integrating related scientific and technological resources, building innovative platforms such as Sichuan Cuisine Industry Research Institute and Sichuan University, and accelerating the digital and intelligent transformation of enterprises in the park.

"We also set up a Sichuan food industry fund with a total scale of 1 billion yuan, focusing on Sichuan seasonings, including Pixian watercress and Sichuan compound seasoning. Next, we will actively pay attention to the new track of food and beverage such as central kitchen and tea, and make forward-looking efforts to broaden the categories. " Zhao Dong revealed that Pidu District will lay out innovation chain around the industrial chain of Sichuan cuisine, aiming at the common bottlenecks of the industry to strengthen technical cooperation. At present, Sichuan Cuisine Industry City has established a shared platform such as Sichuan Cuisine Industry Research Institute, Sichuan Cuisine Industry Park Innovation Center and condiment inspection and testing center. In the next step, it will tackle more than 30 research projects such as automatic circulating water replenishment in fermentation tanks, tank fermentation technology and Sichuan Cuisine processed dishes, so as to enhance the transformation capacity of Industry-University-Research.

Administrative reconsideration and administrative litigation of government information disclosure

  V. Main Problems and Improvements

  1. In terms of policy interpretation, the interpretation of major policy measures still needs to be strengthened, and the interpretation of professional policies is not visual and popular enough. In the next step, we will enrich the forms of policy interpretation, use concise questions and answers on policies, ask about politics on the Internet, and introduce policies into the community, and use charts and diagrams, audio and video, cartoons and other forms that people like to show.

  2. In terms of decision-making, the next step will be to establish and improve the pre-disclosure system for major decisions. For major decisions that involve the vital interests of the public and need to be widely known by the society, all relevant units will be urged to announce the draft decisions and decision-making basis to the public before making decisions, and listen to public opinions extensively.

  Vi. Other matters that need to be reported

  Convene a conference on the compilation of flora and fauna in China
    China Fauna and Flora is a national basic scientific data, which comprehensively and systematically summarizes the species, distribution, systematic relationship and economic significance of China’s organisms, and provides basic data for the exploration and utilization of national biological resources and related construction, scientific research and teaching work. The national flora and fauna is one of the symbols reflecting the development level of a country’s biological science. Many countries in the world attach great importance to compiling national flora and fauna. In 1959 and 1963, China Academy of Sciences established the Editorial Committee of Flora of China and Fauna of China, and organized relevant biologists inside and outside the Academy to compile the Fauna and Flora of China.
  With the approval of the State Council, the conference on the compilation of flora and fauna of China hosted by China Academy of Sciences was held in Guangzhou from February 29th to March 7th, 1973. Attending the meeting were 181 representatives from relevant scientific research units, universities, science and technology management departments, cultural, educational and health units in 26 provinces, municipalities and autonomous regions. This meeting discussed some principles of compiling flora and fauna, such as: compiling flora and fauna should be improved on the basis of popularization, and it should be strict and scientific, reflecting the level of China; We should not only ensure quality, but also strive for speed, so as not to affect quality because of greed and quickness, and also avoid delaying time because of unrealistic requirements for quality; In the deployment of work, it is necessary to prioritize, and concentrate as much as possible on the flora and fauna that are closely related to the economy, important in the scientific sense and rich in information, and prepare them first to ensure completion; Correctly handle the relationship between the compilation of China flora and fauna and local flora and fauna, and pay attention to giving full play to the enthusiasm of the central and local governments.
  At the meeting, the editorial boards of Flora of China and Fauna of China were adjusted and enriched, and the editorial board of Spore Flora of China was established. These three editorial boards are led by the Institute of Botany, the Institute of Zoology and the Institute of Microbiology of China Academy of Sciences respectively. The meeting drew up the compilation plans (drafts) of Fauna of China, Flora of China and Flora of Spore of China. These drafts will be implemented as formal plans after obtaining the consent of relevant competent departments and units undertaking tasks.
  Reprints of China Science and Science Bulletin
  China Science and Science Bulletin, comprehensive natural science journals sponsored by China Academy of Sciences, were suspended for seven years after the Cultural Revolution. At the strong demand of the majority of scientific workers, it was reissued in February this year and publicly issued at home and abroad.
  The editorial board appointed by the Academy of Sciences is responsible for editing the reissue of China Science, which is divided into Chinese and foreign languages. It publishes papers that study natural science theories and summarize production struggles and scientific experiments; Papers from different schools of natural science and articles on major scientific and technological achievements. On February 17th, the Academy of Sciences informed the Science Bulletin that there would be no editorial board, and the editorial board of China Science would be responsible for it. It publishes scientific and technological research achievements, academic trends and some critical articles. In the historical environment at that time, the two publications had to compile and distribute some political articles. The first issue of Science Bulletin was published in July.
  By September this year, there were more than 30 kinds of journals and intermediate academic journals that stopped publishing in 1966.
  Establishment of theoretical system of bulk fluidization in chemical metallurgy
  The theoretical system of bulk fluidization in chemical metallurgy was put forward by Guo Musun, a researcher at the Institute of Chemical Metallurgy, Chinese Academy of Sciences, in his article "Bulk Fluidization in Chemical Metallurgy". This paper was published in the third issue of China Science in 1973, and was read out at the first Iranian chemical engineering conference in May of that year.
  Fluidization refers to the state that solid particles are suspended under the action of fluid, and the particle group at this time is similar to fluid. Generally speaking, fluidization can be divided into two categories: scattered fluidization and aggregated fluidization. The granular materials in the fluidized bed are evenly dispersed and smoothly fluidized, which is called loose fluidization. Usually, liquid-solid systems form bulk fluidization. Fluidization technology has been used in industry for decades and is a mature technology. However, due to the complexity of the movement law of particles and fluids, the complex factors of chemical reaction and reactor, and the fluidization technology itself involves many disciplines such as multiphase fluid mechanics, chemical reaction engineering, particle science and statistics, etc. Although scholars at home and abroad have done a lot of theoretical research work and accumulated a lot, there is no completely unified theory to describe it, and there is also a lack of methods for reactor scale-up and design, so the design scale-up of industrial fluidized reactors is still based on experience.
  Guo Musun’s paper points out the characteristics of a completely uniform ideal fluidization system and explains some concise parameter relations in this ideal fluidization. This theory can be used as a useful tool to analyze many practical fluidization engineering problems, clarify the relationship and operation mechanism of various operating variables, explain some practical phenomena, and have enlightenment significance for the design method and development direction of fluidization technology. On the basis of summarizing predecessors’ work, Guo Musun grasped the characteristics of uniform and stable liquid-solid bulk fluidization, put forward the theory of bulk fluidization, and formed an independent and complete theoretical system, which was a breakthrough in the basic theoretical research of fluidization and applied it in practice. This research achievement won the second prize of the National Natural Science Award in 1982.
  The science and technology group of the State Council Science and Education Group was merged into the Academy of Sciences.
  On August 11th, the State Council Science and Education Group and China Academy of Sciences issued a joint notice to all localities and departments, and China Academy of Sciences was responsible for organizing the formulation of long-term scientific and technological plans and annual plans for civil use, the allocation of three scientific and technological expenses and corresponding materials, and the coordination and inspection of plans. On August 24th, the office meeting of China Academy of Sciences decided that the agency responsible for this work should be the Science and Technology Office of China Academy of Sciences.
  After the merger of the State Science and Technology Commission and China Academy of Sciences on July 1, 1970, China Academy of Sciences set up the first business group (also known as business group 1) to take charge of the work of the former State Science and Technology Commission. After the National Conference on Education in July 1971, the State Council decided to set up a science and education group to take charge of the work of the former State Science and Technology Commission and the Ministry of Education. Li Siguang is the team leader, and Liu Xiyao and Chi Qun are the deputy team leaders. After Li Siguang’s death in 1971, Liu Xiyao took over as the leader of the State Council Science and Education Group.
  In July and August, 1972, the Science and Education Group and the Academy of Sciences agreed that the national science and technology management work should be centralized by the Science and Education Group of the State Council, and the business personnel of the comprehensive plan and scientific experiment dynamic group of the first business group of the Academy of Sciences were transferred to the Science and Education Group to form a science and technology group. In May, 1973, the Science and Education Group asked Premier the State Council and Premier Zhou Enlai for instructions, and thought that the China Academy of Sciences, which is in charge of scientific and technological work in various departments and localities of the national economy, has great limitations, so it is difficult to do a good job and it is easy to attend to one thing and lose sight of another. It is suggested that the scientific and technological work in the production and construction of various departments and localities of the national economy should be planned and coordinated by the State Planning Commission. Medical and health science and technology work is still centralized by the Ministry of Health. The report also puts forward specific suggestions on the tasks and responsibilities of the State Council Science and Education Group in science and technology. The State Council did not reply to the report. However, after the establishment of the Science and Education Group, Premier Zhou Enlai repeatedly suggested that the Science and Education Group should not have more staff, and the scientific and technological work should rely on the China Academy of Sciences.
  In August, 1973, the members of the Science and Technology Group of the State Council Science and Education Group withdrew to China Academy of Sciences, and continued to be responsible for the management of national science and technology work in the name of the Office of Science and Technology. This situation was maintained until the reconstruction of the State Science and Technology Commission.
  Complete the determination of 1.8 angstrom pig insulin crystal structure.
  In August, the Beijing insulin crystal structure research group, composed of the Institute of Physics of Chinese Academy of Sciences, the Institute of Biophysics and relevant personnel from Peking University, completed the determination of the crystal structure of 1.8 angstrom pig insulin.
  The determination of insulin crystal structure began in June 1967. Insulin is a biological hormone, and it is the smallest protein. The biological activity of protein is not only related to its chemical structure (generally called primary structure), but also closely related to its spatial structure (generally called three-dimensional structure). The purpose of determining the crystal structure of insulin is to determine the relative position and relationship of each atom of insulin molecule in three-dimensional space, which can provide an important basis for further studying the mechanism of its biological activity and exploring the relationship between its structure and function. The work of the research group includes: the cultivation of insulin single crystal, the preparation of heavy atom derivatives, the collection and processing of X- ray diffraction data, the calculation of phase angle of structural factors, the analysis and interpretation of electron density diagram, the establishment of structural model and other steps. On the basis of measuring the resolution of 4 angstrom and 2.5 angstrom in September 1970 and January 1971, the measurement of the resolution of 1.8 angstrom was completed in August this year. The research on the determination of the crystal structure of porcine insulin won the second prize of the National Natural Science in 1982.
  Like the synthetic yeast alanine transfer ribonucleic acid, the research on the determination of the crystal structure of porcine insulin was successful in the Cultural Revolution, thanks to the support of Vice Premier Nie Rongzhen.
  The initial-boundary value difference method and the mathematical basis of flow calculation are put forward
  Since 1960, the Computational Mathematics Laboratory has been undertaking the research on aerodynamic and aerothermal numerical methods of missiles and satellites, and has provided a large amount of data for the entrusting department. By the mid-1960s, Zhu Youlan and others put forward a set of systematic and high-precision calculation methods based on the theory of separation singularity and characteristics-the difference method for initial-boundary value problems and inviscid flow, and in 1973 gave the mathematical basis of the methods.
  This method has high accuracy. At that time, because of the equipment embargo, it was impossible to import large-capacity and ultra-high-speed computers, and the aerodynamic force and flow field of aircraft could be well calculated by using the computer developed by China. Not only the shape of the blunt cone can be accurately calculated, but also the shape and flow field of the blunt cone-column-skirt combination can be accurately calculated. It has provided the results of flow field data for the first recoverable satellite in China, and contributed to the safe and accurate return of the satellite to the ground. Users praised this method for giving a set of numerical methods for initial-boundary value problems of hyperbolic equations, which achieved high accuracy and were more perfect, more careful and more unique than similar works abroad. In 1982, this achievement won the third prize of the National Natural Science Award.
  Model 655 computer was successfully trial-produced.
  In 1964, IBM Corporation of the United States announced the successful development of the IBM360 integrated circuit computer system, which opened the curtain of the third generation computer, and this trend attracted the attention of computer technology experts in China. The following year, East China Computing Institute began to develop 655 integrated circuit computers. The required integrated circuits are trial-produced by Shanghai Metallurgical Institute and relevant semiconductor factories in Shanghai. The machine was successfully trial-produced in 1973, with an operation speed of 1 million times per second and a memory capacity of 128,000 words. At that time, it was the fastest integrated circuit computer with the largest memory capacity in China.
  This computer, together with Model 013 integrated circuit computer with a computing speed of 2 million times per second, which was developed in 1976, jointly undertook a large number of computing tasks in the development of atomic bombs, missiles and artificial satellites after the 109 C computer.

Song Joong Ki meets fans. The photo hidden in the mobile phone is actually him.

  Song Joong Ki meets fans. On May 14th, the "2016 Song Joong Ki Asia Tour Fans Meeting" was held at the National Olympic Center Gymnasium. Korean artist Song Joong Ki interacted with fans at the meeting, causing fans to scream. Song Joong Ki will also go to Wuhan, Guangzhou, Shenzhen, Shanghai, Hong Kong, Chengdu and Taipei to complete the fan meeting in eight cities in Greater China.

  I finally waited for you, but I didn’t give up. On May 14th, Song Joong Ki held the first meeting of fans on the Asian Tour in Beijing. Nearly one gymnasium with a capacity of 10,000 people was packed. Song Joong Ki, the "national husband", appeared in the screams of fans with a white shirt and black trousers, and appeared on the lifting platform, just like the prince in every girl’s heart.
