After the summer, for the varieties of melons and vegetables cultivated in the frame, it is necessary to timely pruning and tying the vines, and timely removing the old leaves and diseased leaves. Melons (such as pumpkin, melon, watermelon, etc.) should be artificially assisted in pollination. For the solanaceous fruit (eggplant, tomato), it is still necessary to use the plant growth regulator to prevent the flower from falling or spraying, and as the temperature rises, the use concentration is lowered. Watermelon and melon cultivated in greenhouse or sheltered from rain have entered the fruit setting period or expansion period. The following points should be noted: 1) The fruit of the female flower that appears after the melon is stretched out, and the fruit of the main vine is more than 12 knots. It is not too early to avoid the nutrient growth of the plant. 2) The normal growth of the watermelon head is slightly forward. If the head of the vine grows up close to the sky, it indicates that the vegetative growth is too strong. By artificially pollinating the female flower on the vine, the vegetative growth can be inhibited. To balance nutrient growth and reproductive growth, which is conducive to fruit enlargement. 3) Rainy days will reduce the vitality of watermelon pollen. At the same time, the head of the female flower will also affect the pollination and fertilization. Therefore, in the rainy days, in addition to removing the accumulated water in the shed and reducing the humidity in the shed, the male flowers can be collected early in the day. After drying under the bulb, artificial pollination was carried out the next morning to increase the fruit setting rate. 4) If the water content in the soil increases during long-term rainy weather, it will induce the occurrence of blight (vine disease). It can be prevented by 800-1000 times of pesticides such as wilting and lingzhiling, or 2000 times of rooting prevention. . Nutrients and insufficient water will cause cucumbers, night flowers and other melons or malformed melons. If there are too many melons, you should keep the melons and keep two leaves for one melon. Draw water, control water, wait for most melons to sit for more than 10 cm, properly watering and fertilizing.
