摘　　要：杂交水稻制种在把握好花期和搭建好高产苗架的基础上,扬花期的气候条件是决定其产量的关键因素。本研究根据T优898多年制种扬花期的气象条件及产量水平并结合宜黄县多年气象资料,分析了该组合低产原因,指出了如何合理地选择好扬花期,实现高产稳产。On the basis of well control of flowering period and seedling preparation for high yield, the climatic condition in flowering stage of hybrid rice seed production, is the key factor to its yield. This research, based on climatic conditions of T You 898 flowering stage and its yield level with combination of climatic information of Yihuang County, looks into causes for its low yield and indicates how to rationalize flowering period and have a high and stable yield.
