In the summer, due to the unpredictable weather, some areas will inevitably experience locust plagues, which will cause serious damage to agricultural production. The hazard of hail to crops is mainly bruises, causing mechanical damage, accompanied by frost damage and soil compaction, and after the crops have suffered flood disasters, comprehensive measures should be taken for remedial management.
First of all, it is determined whether or not to overturn crops based on the ability of different crop types and the resilience of different growth periods, and whether the season is sooner or later. In general, as long as the crop has the ability to regenerate and regenerate, the solar term is not too late. If cotton and soybeans are injured at the seedling stage, they are not easily regenerated and regenerated. They must be turned over, and crops with short growth periods must be planted. After the seedling and rooted corn have suffered a locust plague, they can regenerate as long as they remain roots.
Secondly, according to different crops and disaster conditions, timely spraying of plant growth regulators and trace fertilizers, strengthen nutritional supplements, promote root development, and quickly restore growth.
Third, in the absence of seedlings after the disaster, crops with short growing seasons such as soybeans, mung beans, and adzuki beans should be replanted in accordance with local conditions.
Fourth, we must focus on cultivating and weeding to prevent damage to weeds, eliminate compaction, apply topdressing fertilizers, strengthen water and fertilizer regulation, and promote root development.
Fifth, although the branches and leaves after the disaster have been damaged by the injury, they still have the function of photosynthesis and nutrient transportation. Do not lose them easily so as to avoid increasing the damage caused by man-made damages.
Sixth, after the disaster, crops that can be recovered or regenerated are usually matured later. They should be harvested separately according to the situation, and in order not to affect the growth of the crops under the crops, we must seize the favorable opportunity for planting to intercropping.
