我国水稻产区的广大气象台站和农业气象工作者,积极开展杂交水稻气象条件的分析研究和服务工作,在大量调查研究和科学试验的基础上,揭示出杂交水稻生长和气象条件的关系,把指标鉴定、资源分析、服务方法及农业气象基础理论的研究结合起来。近年来,从气象条件上研究杂交水稻的结实率和制种中亲本花时相遇问题取得一定的进展,促进了我国杂交水稻的发展,取得了可喜的成绩。 杂交水稻具有特殊的丰产性能,但杂种优势的发挥与气象条件关系密切。当前我国生产上应用的杂交水稻,由于亲本气候生态遗传影响,一些组合要求较严格的生态环境条件,生育期中的高温强光是发挥杂
Meteorological stations and agrometeorologists in the paddy producing areas of our country actively carry out analytical research and service work on the meteorological conditions of hybrid rice. On the basis of a large number of investigations and scientific experiments, the relationship between the growth of hybrid rice and meteorological conditions is revealed. Index identification, resource analysis, service methods and the basic theory of agricultural meteorology. In recent years, some progresses have been made in the research on the seed setting rate of hybrid rice and the encounter of flowers during seed production in meteorological conditions, which has promoted the development of hybrid rice in China and achieved gratifying results. Hybrid rice has a special high yield performance, but the heterosis play a close relationship with meteorological conditions. At present, the hybrid rice used in the production of our country, due to the climatic and ecological genetic effects of the parents, some combinations require more stringent ecological and environmental conditions, the high temperature and high light in the growth period is to play the role of hybrid
