Answer: 1. According to different varieties, determine the appropriate sowing date and cultivate strong seedlings. 2. Reasonable fertilization and water management. Fertilization is based on the principle of "promoting before, controlling in the middle, and focusing on the back". Water is based on the needs of different physiological periods, from the vine period to the flowering period to ensure sufficient water, increase the water supply during the fruit expansion period, and control water appropriately during the mature period. During the critical period when the fruit is swollen, spraying 0.2% phosphorus and potassium source and reservoir solution on the leaves can improve nutrition and fruit quality. 3. Artificial pollination. In case of rainy and low temperature during the flowering period, both male and female flowers must be bagged for artificial pollination. It is also possible to use pollen from low-temperature-tolerant and early-maturing varieties for artificial auxiliary pollination. 4. Scientific pruning and keeping melons. Watermelons are generally pruned with double vines or three vines. Double vine pruning is to select the main vine and select a strong side vine at the base of the main vine, and remove all the other side vines. When the young fruit grows to the size of a steamed bun, the fruit begins to swell rapidly. At this time, the fruit will generally no longer fall. It is necessary to choose the fruit with good node position and correct fruit shape in time. Double vine or three vine pruning leaves one fruit per plant. 5. Reduce spraying during the flowering period to avoid accidental injury to flower-visiting insects or phytotoxicity. Disclaimer: Some articles on this website are transferred from the Internet.
