水稻有性杂交的去雄最常用的是温水杀雄法。温水杀雄虽然比剪颖法工作效率高,但是经温水处理的穗子不但开颖需要的时间长,而且子房也受到不同程度的伤害,加上一般采用套袋授粉,致使结实率低。1980年我们摸索了一种更为简易的杂交去雄方法—手温暖穗去雄法,并进行了实验验证,效果很好。现介绍如下;

The most commonly used method to eliminate male sexual hybrid rice is to kill male and kill warm water. Although the warm water to kill the male than the shearing efficiency of work, but the warm water treatment of the ears not only open the need for a long time, and the ovary also suffered varying degrees of injury, coupled with the general use of bagging pollination, resulting in low seed set. In 1980 we explored a more simple method of hybridization to male - warm hand spike to male method, and the experimental verification, the effect is very good. Now introduced as follows;
