Diseases and pests of leafy vegetables are numerous, and the treatment is very difficult. Chemical methods (agricultural chemicals) are easier to control and have quick effects, but they affect the quality of vegetables and have great harm to the health of consumers. The use of cultivation methods (mainly rational fertilization) for prevention and control is an effective way to produce pollution-free vegetables. In addition to basic fertilization, leafy vegetables have more diseases and pests, and the treatment is very difficult. Chemical methods (pesticides) are easier to control and have quick results, but they affect the quality of vegetables and are harmful to the health of consumers. The use of cultivation methods (mainly rational fertilization) for prevention and control is an effective way to produce pollution-free vegetables. In addition to the basic fertilization methods, special attention should be paid to the following two points when producing pollution-free vegetables: 1, fully fermented organic fertilizer. The production of "green" vegetables should be dominated by organic fertilizer and less fertilizer. When organic fertilizer is used as a base fertilizer or top dressing, special attention needs to be paid to the fact that organic fertilizer must be sufficiently cooked, and it is best to use a special fermentation agent (such as a goldfish starter) for treatment. This will not only reduce the loss of nutrients, but also completely eliminate harmful bacteria, eggs, and other harmful substances in organic fertilizers and solve the source of diseases and insect pests. 2, the application of high-quality bacterial fertilizer. Biological bacterial fertilizer not only contains a large number of nitrogen-fixing, phosphate-solubilizing, and potassium-releasing active bacteria, but also contains organic matter, humic acid, and trace elements, and can be applied in combination with other fertilizers in any fertilizer-demand period of vegetables. High-quality fungus fertilizers, such as kumquat bacteria fertilizer, can not only save the amount of fertilizer used, but also enhance the pest resistance of vegetables and solve the problem of soil compaction.
