How to manage tomato cultivation? As the weather warms up, the tomatoes are slowly entering the colonization period. This is very important for the management of tomatoes. Then the question is, how should the tomato cultivation in spring be scientifically managed? Please see the key points of tomato science management brought by Xiaobian below. First, grasp the temperature a, tomatoes like warm, hi light. Compared with the cold winter, the spring temperature has risen slightly. It can be said that it is very suitable for the growth of tomatoes. However, it is necessary to pay attention to the daytime temperature of the greenhouse to be controlled at 25 degrees and 15 in the evening. b. If you encounter a colder weather, you can use a small shed and a small arch shed to prevent cold. c. In the greenhouse where the seedling period is slow, it is most suitable to control the daytime temperature of the greenhouse at 30 degrees and 16 degrees in the evening. d. During the flowering and fruiting period, it is most suitable to control the daytime temperature of the greenhouse at 26 degrees and 15 degrees in the evening. e. During the whitish period of the fruit, it is most suitable to control the daytime temperature of the greenhouse at 30 degrees, 15 degrees in the afternoon, and 15 degrees in the evening. Second, rational fertilization When planting, water once. Watering should be poured through the soil. After planting for 7-10 days, pour a slow water. Start seedlings after the slow seedling period, and ensure that the roots are tied down. The seedlings pay attention to the cultivating loose soil, generally cultivating 2-3 times. If the soil moisture is insufficient, water is poured a little while flowering and fruiting, but remember not to flood the water. The fruit grows to the size of the plum, the seedling is over, and the fertilization begins. Fertilization should be carried out in conjunction with watering to help the fruit expand. During the whitish period of the fruit, the second fertilizer is applied and then watered once every other week. Fertilization should pay attention to the appropriate amount of trace elements, mainly phosphate fertilizer potassium fertilizer. During the fruit period, the fertilizer and water should be sufficient and even. At the same time, watering should also be kept at a low temperature. Third, disease pests a. Common pests and diseases of seasonal tomatoes include gray mold and leaf mold; common pests include root-knot nematodes, whitefly, aphids, and Liriomyza sativae. b. For pests and diseases, continue to prevent and treat according to different types of drugs in a timely manner. c, leaf mold: can choose 10% polymycin 800-1000 times liquid spray. Powdery mildew is selected for powdery mildew. Root-knot nematodes were irrigated with 800-1000 times solution of avermectin. d, powdery mildew: use powder rust. e. Root knot nematodes are irrigated with 800-1000 times solution of avermectin.
