杂交水稻烟后制种中采用喷水的方法来增加田间相对湿度，在高温、高湿环境下促进父本花粉多、量大，提高母本受精率，从而增加产量。结果表明：连续喷水（6次）、隔天喷水（3次）与不喷水（对照）比较，结实率分别提高7.0%和4.4%；千粒重增加0.7g和0.5g；实割产量增加47.8和30.3kg/667m2。

In hybrid rice seed production after smoke, this study adopts the method of spray water to increase the relative humidity in the field, in the high temperature and high humidity environment promote the male parent pollen, more quantity is big, improve maternal fertilization rate, thus increasing production. The results show that the continuous hydraulic (6 times), the next day (three times) compared with no water (control), seed setting rate increased by 7.0% and 4.4% respectively; Thousand seed weight increased by 0.7 g and 0.5 g; Solid cutting yield increased by 47.8 and 30.3 kg/667m2.
