At the same time, the suitable temperature, humidity, 10cm ground temperature, and sunshine hours for female flowers to successfully catalyze are identified, and further exploration is conducted on the meteorological factor regulation technology of facility watermelon female flower catalysis. The results showed that there is a close correlation between meteorological factors and the catalysis of female watermelon flowers, and temperature has the greatest impact on the catalysis of female watermelon flowers. The regulation of meteorological factors in facilities can effectively promote the catalysis of female watermelon flowers when the temperature is 19~20˚C, the sunshine hours are 6~10 hours, the 10cm ground temperature is 18~22˚C, and the relative humidity is 57~58%, which is conducive to solving the problems of sparse female watermelon flowers, difficult melon sitting, and only flowering but not bearing fruit in facilities.展开更多
