Description

A Method of Controlling Vegetable Soil-Borne Diseases at Local Fixed Points

technical field

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

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 to survive, and the proliferation of pathogenic bacteria aggravates the occurrence of soil-borne diseases, especially the vegetable wilt caused by Fusarium , Pythium , and Phytophthora ( Root rot caused by Phytophthora ), Verticillium wilt caused by Verticillium and Plasmodiophora brassicae and other soil-borne diseases have complicated pathogenesis, rapid spread and serious damage, causing losses larger.

At present, the methods commonly used to prevent and control soil-borne diseases of vegetables include physical control methods and chemical control methods. Physical control methods include crop rotation, cleaning up diseased plants, etc. Physical control plays a preventive role to a certain extent. Once a disease occurs, physical control cannot absolutely control it. Chemical control methods include soil spraying with chemicals, root irrigation with chemicals, soil mixing with drugs, and soil disinfection. The chemical spraying soil method only has a certain inhibitory effect on soil surface diseases. At the same time, the chemical is easily volatilized and photolyzed when exposed to the environment; the chemical root irrigation method cannot make the chemical evenly distributed in the soil, and the dosage is large , high cost, poor environmental safety and serious environmental hazards due to residues; the drug mixing soil method has a slightly longer duration, but after several times of watering, the drug effect is reduced after the drug is dispersed under the action of the water flow, and it cannot play a role on the roots of vegetables. Long-term protective effect; soil disinfection method is one of the effective measures to prevent and control soil-borne diseases, but most of them are limited to facility agriculture, and it is difficult to realize in field agriculture. Such substances are highly toxic, and soil disinfection is non-selective , can not only kill harmful organisms, but also kill beneficial organisms and destroy the soil ecological environment.

Due to the limitations of the above methods for preventing and controlling soil-borne diseases of vegetables, the patent CN100515193C discloses a method of using a drug isolation film to prevent and control vegetable root diseases. The outside of the plant is planted together, and the combination of physical control and chemical control is used to isolate soil-borne diseases and protect the healthy growth of roots for a long time. 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, increase the operation steps, and need further improvement.
