Reasonable rotation
Such as the solanaceous vegetables and onion and garlic vegetables, not only can significantly reduce the disease, but also have the effect of increasing production.
Removal of diseased plant residues
It is a good method to prevent pests and diseases by removing the residuals, diseased fruits and weeds of the diseased plants, destroying the deep burial and cutting off the transmission routes.
Reduce humidity
Because the bacteria can multiply in large humidity and harm the vegetables, the humidity in the field should be reduced as much as possible to reduce the occurrence of diseases.
Rational fertilization
It is best to use formula fertilizer on vegetables, and mainly to increase the application of decomposed organic fertilizer, combined with the application of phosphate fertilizer, control the application rate of nitrogen fertilizer, and use the nitrate inhibitor dicyandiamide in the later stage of growth to prevent nitric acid in vegetables. Salt accumulation and pollution.
Soilless culture
The use of soilless culture can artificially reduce the source of germs, which is a good method.
Set up insect net
If it is a greenhouse vegetable, an insect net is installed in the vent of the shed to prevent the invasion of pests such as whitefly and mites, and reduce the chance of infection.
