Cause Analysis The planting is too deep. Some vegetable farmers have buried one-third of the stems in the soil. Due to high temperature and high humidity, the stems turn brown and even rot, but this is not a disease and cannot be prevented by spraying. Seedling seedlings require an adaptation process. Since the seedlings have been adapted to the soil environment of the seedbed before planting, it is necessary to have a certain time to adapt to the soil environment in the arch shed after the planting, which results in a longer incubation time. The method of colonization is incorrect. Because most of the vegetable farmers did not take ridges and colonization, and most of them adopted the method of flooding with large water, the permeability was not good, resulting in roots. When the wilted seedlings are pulled out, it can be clearly seen that some of the capillary roots have been necrotic, and the remaining roots are insufficient to maintain the nutrients and moisture required for their normal growth. When the temperature is high on a sunny day, the amount of transpiration of the plant is large, and the water required is large, so the wilting phenomenon occurs. White powder is harmful. Whitefly is very harmful, not only can absorb the juice of the plant, but also spread the virus. Because of its strong reproductive ability and rapid reproduction, it is necessary to step up prevention and control. Prevention For the case of deep planting, to strengthen the field management, you can use a small tool to dig a digging around the seedlings, so that the stalks buried in the soil are exposed to the soil. Appropriate cultivating and slashing, increase soil permeability, avoid rotten stalks, and cause dead trees. For the phenomenon that the hairy roots of the seedlings are necrotic and no new roots are produced, rooting and seedlings can be added to the roots to prevent the soil-borne diseases and promote new roots as soon as possible. For whitefly, you must pay attention to prevention in advance, or you can spray in the early stage of pests: you can use 25% of chlorpyrifos 1000 times solution or 1.8% of avermectin emulsifiable concentrate 3500 times solution, 40% of imidacloprid can be used. The solvent was sprayed with 4000 times of liquid. It is best to add Plex and some fungicides at the same time as spraying to prevent the occurrence of diseases and some bacterial diseases.
