The development of agricultural science and technology in new China is a national act, and it is always an organized, planned and cooperative project. Every major study is not an isolated individual act. As early as the period of mutual assistance and cooperation, agriculture began to cultivate and popularize excellent varieties in an organized way. China Academy of Agricultural Sciences was established in 1957, and formulated the planning and tasks of agricultural scientific research. According to the plan at that time, the cultivation and popularization of improved varieties and the prevention and control of pests and diseases were regarded as one of the key tasks of agricultural science and technology. To this end, the state has invested a lot of manpower and financial resources. From the late 1950s to the early 1960s, excellent new varieties such as wheat, rice, hybrid corn and sorghum cultivated by relevant scientific research departments began to be popularized in production. These new varieties are constantly updated, which gradually improves the agricultural output. From 65438 to 0966, the third national crop breeding conference was held. At the meeting, all localities exchanged experiences and recommended 72 newly bred fine varieties of food crops and cash crops. At that time, governments at all levels and local people's communes attached great importance to the improvement and breeding of crops, and generally carried out mass seed selection and promotion activities, which achieved remarkable results. As early as 197 1 in southern rice areas, the planting area of improved varieties reached 80% of its total area; The sown area of hybrid sorghum has reached 20% of the whole country; Hybrid corn accounts for about one third; Wheat varieties with rust resistance, lodging resistance and high yield have been widely popularized.

As far as the research and improvement of rice varieties are concerned, scientific research departments, scientific and technological workers, people's communes and production teams in more than a dozen provinces are engaged in this work. Its outstanding achievements have been widely promoted for more than a dozen times. For example, scientists and technicians in China have cultivated new rice varieties such as Huayu 1, Huayu 2, Shanfeng 1 and Peony 1 by using the pollen haploid breeding method, which greatly increased the yield, and the yield per mu reached more than 1000 kg. Among them, Yuan Longping was not the first person who succeeded in the research and experiment of hybrid rice. For example, Li Zhensheng (Korean), a member of Hewa Commune in Hailong County (meihekou city), Jilin Province, successfully cultivated new hybrid rice varieties in 1967, and was the first person to cultivate hybrid rice in New China. From 65438 to 0968, he cultivated hybrid rice seeds, corn rice, sorghum rice and sunflower rice with Hailong Agricultural Science Station and "May 7th Middle School" in Hailong County. If there is a "father of hybrid rice", it should be Li Zhensheng and his colleagues. Their experimental results laid a foundation for hybrid rice in China. The achievements of Li Zhensheng and others were incorporated into the middle school textbooks of Jilin Province at that time as teaching contents, and a science and education film was also filmed. Because Li Zhensheng didn't receive much education, he couldn't write a paper and died early (more than 20 years ago), so he didn't get any honor. Later, Yuan Longping won the first special invention award in China, the UNESCO Science Award, and was the father of hybrid rice.

Yuan Longping's research on indica hybrid rice began with 1964. 1972, the Ministry of Agriculture listed hybrid rice research as a national key scientific research project, forming a nationwide scientific research cooperation network. 1973 The new hybrid varieties of Yuan Longping Group were successfully tested, and 1976 approved large-scale planting. Results The yield of rice increased by more than 20%, and the yield per mu reached more than 600 kilograms. This was indeed a great achievement of agricultural science and technology at that time. It has made great contributions to improving rice yield in South China. However, at that time, Yuan Longping Group was not the only one engaged in rice variety cultivation and testing in China. There are about 167 scientific research units, hundreds of researchers and tens of thousands of farmers in rural communes and production teams in China. Have made remarkable achievements. New varieties appear everywhere, such as flowers blooming. At that time, it was not uncommon for rice to yield more than 600 kilograms per mu. Many new achievements were published and reported in People's Daily at that time. At that time, the whole country didn't know there was a Yuan Longping. During the period of 1978, the Ministry of Agriculture and Forestry held a breeding promotion meeting for hybrid rice, hybrid corn and hybrid sorghum (then called "Sanza") in Yaxian County, Hainan Island. At that time, more than ten people introduced their experiences, including Yuan Longping. Yuan Longping is really famous because of his laziness after 80s. In the 1980s, due to the division of fields to households and the dissolution of people's communes, it became very difficult to test and popularize improved varieties in various places, and most of the work stopped. This is also one of the reasons why China's grain output has declined since 1985 and entered a long-term wandering situation. ..... From the 1990s to the beginning of this century, Yuan Longping studied "super hybrid" rice, making the yield per mu reach 700kg and 800kg successively. At present, many rice varieties in the north and south of China are close to tons of grain (yield per mu 1000 kg), and his varieties have no advantage. In recent years, Yuan Longping has issued a declaration to challenge 900 kg/mu, 1000 kg/mu and "transgenic", but it will take some time to realize it in practice. If hybrid rice made Yuan Longping, then the role of propaganda and public opinion will be more and more included in the later aura! Just extract some.
