Method for local fixed-point control on soil-borne disease of vegetables

Abstract

The invention relates to a method for local fixed-point control on soil-borne disease of vegetables. According to the method, two measures, i.e., medicated seedling raising bags and medicated matrixes are combined, the medicated matrixes are loaded into the medicated seedling raising bags, seedling raising is carried out after watering, and young seedlings are transplanted to greenhouses or fields together with the medicated matrixes and the medicated seedling raising bags during fix-planting. On one hand, stem bases and root upper parts, which are susceptible to infection, of the young seedlings of the vegetables are protected by the medicated matrixes and the medicated seedling raising bags and are isolated from germ-carrying soil, so that a long-lasting protective effect on roots of the vegetables is achieved, and the effect of preventing and lowering the frequency of occurrence of disease for the roots of the vegetables is achieved; and on the other hand, the growth of the roots of the vegetables is free from the restriction of the seedling raising bags, and the roots of the vegetables can penetrate through the seedling raising bags and freely extend towards the fields, so as to achieve the aim of local fixed-point control on the soil-borne disease of the vegetables. The medicated seedling raising bags and the medicated matrixes are combined with the method for local fixed-point control on the soil-borne disease of the vegetables, and one-time operation is required only during sowing, so that the method is simple and convenient and is low in cost and remarkable in effect; and the consumption of pesticides can be reduced, the environmental safety is enhanced, the labor intensity for farmers is lowered, and the popularization is facilitated, so that the method is a first-choice effective prescription for the prevention and treatment of root disease during the production of pollution-free vegetables and the production of green vegetables.

Description

technical field [0001] The invention relates to a method for local fixed-point control of vegetable diseases, in particular to a method for preventing and controlling soil-borne fungal diseases of vegetables by using a drug-containing seedling-raising substrate and a drug-containing seedling-raising bag. Background technique [0002] Soil-borne diseases are one of the most important causes of soil continuous cropping obstacles. In recent years, with the continuous improvement of the multiple cropping index of vegetables and the single planting of protected vegetables, the occurrence of vegetable soil-borne diseases has become more and more serious, which has seriously restricted the development of the vegetable industry. How to solve the problem of soil-borne diseases has become particularly important. Vegetable continuous cropping provides the host and breeding place for root diseases, and the proliferation of pathogenic bacteria aggravates the occurrence of soil-borne dise...

However, the isolation film needs to be soaked in the fungicide. Different isolation materials and medicaments have different adsorption. When using it, the concentration of the immersion drug needs to be adjusted, and the process of immersion and drying is also required. In addition, the isolation film needs to be rolled into a cylinder when used. , wrapped outside the soil-containing seedlings, increasing the operation steps, further improvement is needed
