The interruption of greenhouse tomatoes can reduce unnecessary nutrient consumption, reduce the probability of disease occurrence, enhance the lighting effect of the ventilator, and promote the growth of crop roots.
1. It is best to choose a sunny day for the interruption, which is conducive to the healing of the wound that appears after the interruption. When interruption is continuous, the speed of wound healing is very slow, which makes it possible for bacteria to invade. The bacteria will soon cause a large area after entering from the wound. Of contagion. In the evening, try not to interrupt. The humidity in the greenhouse at night is high, and unhealed wounds are easily attacked by diseases at night. It is best to stop at noon when the air humidity is relatively low to reduce the chance of plant infection.
2. It is best not to interrupt for about two days after each watering. Because the water content of the plants after watering is large, the wounds produced after interruption will be larger and will not be easy to heal. In order to avoid infection and disease, it is best to interrupt the operation two to three days after watering, and choose the Sunny morning.
3. After the tomato enters the fruiting period, pay attention to not too much interruption. In order to promote the growth of the roots of the crop and the development of the plant, the branches and leaves must have a certain area, otherwise it is not conducive to the differentiation of flower buds.
4. The plants that have been infected with the disease should be interrupted separately to prevent the disease from spreading through people.
5. Drugs can be used to prevent diseases after the interruption, and azoxystrobin, chlorothalonil and other drugs can be sprayed on the stems to prevent the spread of diseases.
