From 65438 to 0958, Chen Yongkang, a national agricultural high-yield model, put forward the "Three Huang San Blacks" experience of single-season late rice high-yield at the "National Rice High-yield Science and Technology Exchange Conference" in Suzhou, which attracted the attention and interest of the participating experts. That autumn, Chen Yongkang was transferred to Jiangsu Branch of China Academy of Agricultural Sciences for high-yield rice cultivation. Yang was ordered to form a cooperative group with Cui Jilin and Tang Yugeng, including cultivation, physiology, soil and fertilizer, meteorology, plant diseases, agricultural physics, etc., to carry out comprehensive research with high yield of rice as the overall goal. During these three years, Yang not only presided over the daily work of this collaborative research, but also insisted on participating in the research activities of the cultivation professional group and learning from the field operation techniques. The cooperative group believes that Chen Yongkang's seedling diagnosis technology aims to strive for a healthy appearance under the comprehensive consideration of "looking forward and looking back", take leaf color as a sensitive signal, measure the growth and predict the appearance, so as to make a comprehensive health diagnosis. They expounded the internal essence and biological mechanism of the alternate change of leaf color "black" and "yellow", and on the basis of demonstrating the scientific basis of high-yield technology in Chen Yongkang, formulated the diagnostic index of coordinated growth in each growth period. Subsequently, Yang Wei wrote a series of papers. Among them, 1964 read out the article "Diagnosis and Cultivation Techniques of Late Japonica High-yield Seedlings" at the Beijing Science Seminar, which aroused great interest from experts from all over the world. Other experts in the collaboration group also published many papers from different professional angles, demonstrating the scientific connotation of Chen Yongkang's rice high-yield experience, which greatly improved people's understanding of Chen Yongkang's high-yield experience.
In order to transform scientific research achievements into productive forces, 1962- 1965, members of Yang, Yang, Yang and Yang successively established "demonstration sites" for high-yield rice technology, planted demonstration fields, sent scientific research achievements to rural areas, took farming classes at the demonstration sites, and trained a large number of grassroots personnel inside and outside the province. According to incomplete statistics, there are 5.8 million mu of rice in Suzhou alone, from 196 1- 1969. Due to the application of this high-yield cultivation technique in Chen Yongkang, the yield per mu has soared from about 250kg to about 450kg. According to incomplete statistics of Jiangsu, Zhejiang, Shanghai, Anhui, Hunan, Hubei and other provinces and cities, the total number of paddy fields that have applied or partially applied this technology is about 65.438+0.5 billion mu, with an increase of about 33.2 billion kilograms.
It is an innovation that the institute adopts a series of measures, such as the combination of scientific and technical personnel and model workers, multidisciplinary and multi-sectoral comprehensive research, the combination of laboratories, experimental demonstration sites and large-scale production, the establishment of demonstration sites in rural areas, the transformation of scientific research results into productive forces, and the training of grassroots technical backbones through demonstration sites. At the same time, this study also enriched the content of rice cultivation.
This research won the National Science Conference Award of 1978. As the host, organizer and participant of this study, Yang devoted a lot of energy and wisdom to it.
