In order to avoid or mitigate the negative impacts of heavy barriers on crops, comprehensive adjustments and governance should be carried out in terms of preventive measures. Implement a rotation. For field crops or vegetable plots where the virus source and infectious diseases have caused serious damage, it is necessary to carry out a rotation for 2 to 3 years. It is best to carry out water and drought rotation, which can better prevent diseases. The second is to increase the application of organic fertilizer.
Each mu should be used to apply 4000~5000 kg of decomposed homeland fertilizer, or 2500~3000 kg of bio-organic fertilizer, or 80-150 kg of bio-organic compound fertilizer, which can improve the soil organic matter content and inhibit the activities of some harmful microorganisms. At the same time, according to the needs of different crops, the application of a certain amount of potassium fertilizer in organic fertilizer can alleviate or mitigate the damage to blight.
Where there are conditions and technical basis, the application of plant gene inducer to root or spray can promote the growth of crop roots, improve photosynthetic efficiency, enhance stress resistance, better prevent pests and diseases caused by heavy mites, and increase yield. Improve quality.
