对豇豆杂交人工授粉的2种环境条件和2种授粉方法的结荚率和结荚指数进行比较。结果表明，露出柱头法的综合效果好于去瓣去雄法，双层遮阳网覆盖的授粉效果好于自然环境条件。
Two kinds of artificial pollination of cowpea hybridization were compared with the podding rate and pod index of two pollination methods. The results showed that the combined effect of exposing the stigma method was better than that of the detrigger and removing male method. The pollination effect covered by the double shading net was better than the natural environmental conditions.
