There are many pests and diseases that produce the two elements of green leeks, and the treatment is very difficult. The main diseases are gray mold, epidemic disease, cockroach, green onion thrips, green leaf spot fly and so on. The use of chemical methods (pesticides) is relatively easy to control, and has quick results, but it affects the quality of leeks, which is very harmful to the health of consumers. Using cultivation methods (mainly rational fertilization) to prevent and control is an effective way to produce non-pollution leeks. In addition to the basic fertilization methods, the following two points should be paid special attention to the production of pollution-free leeks:
1, fully fermented organic fertilizer. The production of "green" leeks should be dominated by organic fertilizers 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 leeks. High-quality fungus fertilizers, such as gold treasure bacteria, can not only save the amount of fertilizer used, but also enhance the pest resistance of leek and solve the problem of soil compaction.
