摘要
从杂交稻旱育抛秧不同的水层深度、秧苗素质、根部带土与否和立苗效果等３个方面，安排试验进行考查，并从今后大面积推广的角度出发，对杂交稻抛秧适宜的基本苗数；秧苗素质；肥水促控；病虫害防治等问题也提出相应的措施进行讨论。
The biosynthesis of gibberellins in rice plants was introduced and the relationship betweenthe fertile alteration and gibberellins on photoperiod─sensitive genic male─sterile rice was discussed basedon the research work.
