3-5 days after the temperature management of the shed period, closed insulation, promote the slow seedling under the condition of high temperature and high humidity; keep the temperature at 25-30 °C during the daytime, keep at 15-20 °C during the night, and leeward at 30 °C Ventilation. When the outside temperature is stable at 20 °C, the greenhouse film is rolled up and ventilated on both sides to cool down, ventilate and enhance the light. Pruning and vine: 1 whole branch of early-maturing watermelon pruning is generally dominated by one main side or one main side. The other side branches are removed in time before the melon is placed to promote growth. After the fruit is placed, it is generally no longer pruned. The main vines can be topped 25-28. Timely vines, the main vines are directed to the center of the greenhouse, and the vine leaves are evenly distributed. Each vine grows 30-50 cm and needs to be pressed once, and the leaves are heavy. 2 Artificial pollination selects the female flowers above the 12th leaf on the main vine (the 2nd and 3rd flowers) to grow into high quality large melons. The artificial pollination and the opening of the female flower were carried out at 7-9 am on the same day, and the male flower pollen opened on the day of picking was applied to the head of the female flower. Due to the low insect activity, artificial assisted pollination is used to increase the fruit setting rate. 3 Select melon, melon, usually in the fruit type, each strain is selected to retain a fruit-shaped melon, and each of the small fruit types is selected to retain two fruit-shaped melons. It is required to choose the first melon fruit festival to stay in 12-18 knots, and to achieve timely fruit thinning, to concentrate nutrients to promote fruit enlargement and increase the weight of single melon.
