影响杂交水稻结实率的因素分析及其关键调控技术

Analysis of Factors Affecting Seed Setting and its Key Regulation Technique in Hybrid Rice

结实率的高低和稳定性是影响杂交水稻高产和稳产的重要因素。遗传因素、生理因素、自然生态条件和栽培技术措施都对杂交水稻的结实率有重要的影响。文章就影响杂交水稻结实率的4个因素作了评述,并讨论了提高杂交水稻结实率的关键调控技术。

The seed setting and its stability in hybrid rice contributed to high and stable grain yield. Seed setting was influenced by genetic, environmental, cultivated and physiological factors. The four factors were analyzed in this paper, and the key technique which increased Seed Setting rate was disscussed.
