It was learned from the ten-year development report meeting of the Chinese Academy of Agricultural Sciences held on the 28th that since the 18th National Congress of the Communist Party of China, the Chinese Academy of Agricultural Sciences has made a series of major original scientific and technological achievements focusing on solving major scientific and technological problems in China's agricultural development, focusing on the forefront of world agricultural science and technology, responding to major national needs, engaging in the main battlefield of modern agricultural construction, and facing people's life and health. Ten landmark scientific and technological achievements of the Chinese Academy of Agricultural Sciences in the past ten years were released at the meeting, which were as follows: there were many breakthrough new discoveries in crop omics and genetics, challenging traditional scientific cognition; The pest control system of crops is becoming more and more perfect, and "insects eat grain" to ensure a good harvest; The technology of cultivated land protection and land productivity improvement has been upgraded iteratively, and the "lifeblood" of grain production has been firmly guarded; Green agricultural technology and products bring forth the old and bring forth the new to retain the common people's "golden mountain and silver mountain"; Highly pathogenic avian influenza was successfully prevented and controlled, and the "human disease and animal prevention" system led the world; The quantity and quality of the new varieties of food rations have risen, and they are filled with Chinese "food bags"; High oil rape, high-quality vegetables, etc. help the integration of three industries and create a "new engine" for rural revitalization; Breakthrough domestic poultry varieties were approved one after another, and Chinese people put "Chinese poultry" on the table; Specialized large-scale livestock breeds are cultivated independently, and the era of "choke" is gone forever; The inspection of agricultural products "drove into the expressway", so that people could see clearly and eat at ease. Zhang Geng, secretary of the Party Leadership Group of the Chinese Academy of Agricultural Sciences, said that in the past decade, the Chinese Academy of Agricultural Sciences has fully supported the implementation of the strategy of "storing grain on the ground" and "storing grain in technology", making a historic breakthrough. In terms of tackling key problems in grain ration and grain high yield and quality technology, rice breeding has achieved a significant improvement in quality. "Huazheyou 261" has greatly improved the quality of super rice taste quality, and the application area of "Zhongjiazao 17" has ranked first in the southern rice region. Wheat breeding has broken through the bottleneck of high yield and high quality compatibility. The high-quality and strong gluten wheat "Zhongmai 895" has been promoted for more than 51 million mu, and its filling rate and heat resistance rank first among the main varieties in the Huang Huai wheat region. The average yield of "Zhongmai 578" high-yield demonstration field is 841.5kg/mu, and the bread quality reaches the level of imported high-quality wheat. The technology of dense planting of maize has set a record of high yield, with the highest yield per mu reaching 1663.25 kg. The soybean variety "Zhonghuang 13" has been promoted for more than 100 million mu, ranking first in the country. In terms of farmland quality protection and use control capability, CAAS has significantly improved its ability to support the quality protection and land productivity improvement of "seven plots" of land, including northeast black land, northern dry land, southern paddy field, southern dry land, saline alkali land, facility agricultural land and reserve farmland. Integrate the comprehensive prevention and control technology of typical red soil farmland acidification, demonstrate in large areas in six provinces, and increase the grain yield by more than 12%; Establish a technical system for improving low yield paddy soil and improving soil fertility in the south, and increase rice production by more than 100 kg per mu in the demonstration area; Establish key technologies to improve soil organic matter in farmland of major grain producing areas. The content of soil organic matter in the demonstration area will be increased by more than 12% and the yield will be increased by more than 5%. The all-around high-precision digital soil monitoring system has been fully established to realize "sky view, online search and ground management" of farmland utilization, providing scientific basis for high standard farmland use control.
