中国科学院长沙农业现代化研究所与日本“中国农业现代化研究会”合作,在湖南省桃源县进行的“中稻栽培技术体系”的研究,获得了成果。经中国科学院鉴定,这项研究具有国内先进水平,对促进我围水稻生产,合理调整作物布局和农业全面发展都具有重要意义。我国现有中稻播种面积1.8亿亩,中稻生产逐步发展起来。1980—1984年中、日两国科技人员协作,经五年的试验研究,进行了成套技术组装,在一万亩稻田内示范,取得了丰富的数据,主要成果有以下几个方面:1.从国外引进150多个中稻品种中,筛选出12个优质、高产的新品种。2.试验总结出获得高产、优质产品的最优抽穗、灌浆期。3.采用了窄行、少苗、壮秧的本田栽植方
Changsha Institute of Agricultural Modernization, Chinese Academy of Sciences and Japan “China Agricultural Modernization Research Association,” carried out in Taoyuan County, Hunan Province “Mid-crop cultivation technology system” research, and achieved results. The Chinese Academy of Sciences identified that this study has the domestic advanced level, to promote the rice production around me, a reasonable adjustment of crop layout and agricultural all-round development are of great significance. China’s existing mid-sown area of 180 million mu of rice production gradually developed. During 1980-1984, scientists and technicians from China and Japan collaborated. After five years of experimental research, they completed the assembly of complete sets of technologies and demonstrated their experiences in 10,000 mu of paddy fields. They have obtained a wealth of data. The main achievements are as follows: 1. Introduced more than 150 middle-rice varieties from abroad, 12 high-quality and high-yield new varieties were screened out. The experiment summed up to obtain high yield, high quality products, the optimal heading, filling period. 3. Using a narrow line, young seedlings, strong plant Honda planting side
