The female flower of gourd, bitter gourd and sponge gourd were artificially pollinated on the day of flowering. The fruit set rate could reach more than 95%, and higher seed yield could be obtained. The fruit yield and seed yield both showed pollination on the flowering day Day pollination> Flowering pollination on the third day. The rate of fruit set of pollination of pollination can reach 80% on the second day after flowering. The percentage of fruit set on pollination of bitter melon on the second and third days of flowering can reach 50%.
