Entrusted by the State Science and Technology Commission and the Ministry of Agriculture, 198 1 presided over the national key scientific and technological project "Breeding of new wheat varieties with high and stable yield and research on its theoretical methods" during the Sixth Five-Year Plan and the Seventh Five-Year Plan. He and the members of the research group consciously implemented the policy of science and technology serving economic construction, vigorously carried out regional trials of large-scale regional varieties, and closely linked with regional trials of provincial varieties to speed up the transformation of improved varieties into productive forces and expand the scope of application; At the same time, attention should be paid to arranging relevant supporting research, enhancing breeding stamina and continuous innovation. In addition, he also actively advocated the exchange of materials and experience, carried out shuttle breeding, and took various measures to mobilize the enthusiasm of participating units. 1983 In March, at his initiative, the cooperative group held the "First Academic Experience Exchange Meeting of National Wheat Breeding Cooperation" in Yangling, Shaanxi, which achieved good results in exchanging information and updating knowledge. The collection of essays published after the meeting was named "Progress in Theory and Practice of Wheat Breeding", which was published by Popular Science Press. Under his leadership, the cooperative team not only successfully completed the task of tackling key problems in the Sixth Five-Year Plan, but also overfulfilled the target of tackling key problems in the Seventh Five-Year Plan ahead of schedule, laying a solid foundation for upgrading wheat varieties in the Eighth Five-Year Plan. After the National Science Conference, the subject of winter wheat breeding in his unit has won five national or ministerial awards. Among them, "12057", "Kang Feng No.8" and "Kang Feng No.8" won the first prize of the Ministry of Agriculture, Animal Husbandry and Fisheries and Beijing Science and Technology Progress respectively (1983,1984); The breeding and development of "Kang Feng 13" won the third prize of scientific and technological progress of the Ministry of Agriculture (1988); The results and application of the national wheat regional test in the Sixth Five-Year Plan won the second prize of the National Science and Technology Progress Award (1987). He was awarded the National Advanced Individual Award for Science and Technology in the Sixth Five-Year Plan by the State Planning Commission, the State Economic and Trade Commission, the State Science and Technology Commission and the Ministry of Finance (1986) and the Advanced Individual Award for the Service of the Four Modernizations by the federations of industry and commerce of democratic parties (1985).
