How to improve greenhouse fruit melon fruit setting rate

First, improve the ecological environment. First, we must eliminate waterlogging around the planting areas and promote hair rooting. Second, we must uncover the plastic film, remove the cover as soon as possible, and fill both the light and the heat. Third, we must uncover the two films or the base of the film to supplement the scattering light source on the rainy day. . Second, regulate the growth of melon vines. In melon field where Muskmelon has been very effective, spraying with paclobutrazol, spraying 10 ml per mu with 40 to 50 kg of water, can significantly inhibit the growth of melon vines, promote ovary hypertrophy, and promote fruit enlargement. Third, induced female flowers sitting melon. It can be used to treat female flowers, such as sitting on the melon, or setting fruit, which can increase the fruit setting rate to more than 90%.
