When farmers carry out daily shed operations such as pruning, fork, fruit picking, etc., they often leave many large and small wounds on the "body" of vegetables. These wounds will heal quickly in normal weather, but in rainy weather. When the humidity is high, the wound is easily infected by germs and infection.
Therefore, usually we must pay attention to the protection of these wounds, especially when the weather is changeable and there are many cloudy weather, it is particularly important to protect these wounds on the "body" of vegetables.
1. Try to avoid leaving wounds on the "body" of vegetables in rainy days. If the shed cannot be opened on cloudy and rainy days, the humidity in the shed must be high, which is very suitable for the occurrence of some bacterial diseases. Therefore, in bad weather, vegetables should try to avoid the above operations. Sometimes when vegetables encounter continuous cloudy days after pruning and fork, they should be sprayed with 1500 times of agricultural streptomycin or 500 times of DT in time to prevent problems.
2. Pay special attention to the wounds on the vegetable "body" on the front face of the greenhouse. Because the dewdrops of the shed film on the front face of the shed often gather here, and the humidity is higher than that in other places, the wounds on the "body" of the vegetables planted here are also more likely to be infected with bacteria. When spraying at ordinary times, special "care" should be given to the vegetables on the front face, and spray finely and evenly. In addition, for the wet soil in front of the shed, it must be covered with film to reduce the humidity here as much as possible to create a good environment for it.
3. Special attention should be paid to the treatment of vegetable grafting. From what the reporter learned from going to the countryside, the grafting port of vegetables is a place where diseases are prone to occur. Many vegetable farmers cause frequent diseases due to improper handling of the grafting port after the vegetables are grafted. It is understood that the diseases easily infecting vegetable grafts include blight, blight, root rot, fusarium wilt and sclerotinia. Root rot can be controlled by Anke, Meike, Plik and Jinlei, Fusarium wilt can be controlled by oxbendazim, Tuxojing and tolfos-methyl, and Sclerotinia can be controlled by Socoling, Prohein and Nongliling prevention and treatment.
4. Minimize the micro wounds caused to vegetables in the shed operation. In the shedding operations such as falling vines and spraying, it is easy to cause some micro wounds on the "body" of vegetables. These wounds are also susceptible to infection by some bacteria when the humidity in the shed is high. Therefore, vegetable farmers must pay attention to "lightness" and "softness" in the future shed operations, and take care of them carefully. Only in this way can the growth of vegetables be more robust.
