Soil Disinfection Method for Medicinal Plant Cultivation Base

Abstract

The invention discloses a soil disinfection method matching with medicinal plant cultivation bases, the method comprising following steps: (1) for seed germination substrates: performing steam disinfection to the crushed and well mixed seed germination substrates. The incidence of disease is reduced below 90%. The incidence of pests and soil nematodes is reduced below 99%. Weed eradication rate reaches 100%. (2) For the field cultivation soil: performing prevention and treatment by combined method of daylight UV radiating, novel low toxicity and low residual agents fumigating or spraying . Compared with traditional chemical disinfection method, the novel and low toxicity pesticide which has a short decomposition period under sunlight radiation and in soil is adopted in the provided method, and the residual quantity of the pesticide after one week is lower than 0.1 mg / kg, reaching pesticide residue standards established by the United States and the European Union. Thus, pollution to the air, water source, the soil and crops is effectively reduced. Compared with modern physical disinfection methods which are more dependent on development of new technology and investment of high cost equipment, the provided method has following advantages: simple equipment is adopted; cost is low; technology popularization and promoted application in large area are facilitated.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a soil disinfection method for a medicinal plant cultivation base. Background technique [0002] In recent years, with the popularization and promotion of protected cultivation and the increase of greenhouse and greenhouse cultivation in agricultural production, a variety of pathogenic bacteria and soil pests have accumulated in the soil, resulting in crop yield reduction or even failure. Since most diseases in greenhouses, greenhouses, and planting bases are transmitted by soil, soil disinfection is an effective way to prevent the occurrence of some diseases and insect pests and effectively alleviate the obstacles to continuous cropping. At present, the traditional soil disinfection methods mainly include physical disinfection methods and chemical disinfection methods. At the same time, reasonable crop rotation methods and formula fertilizer technology can also be used to improve th...

AI Technical Summary

Problems solved by technology

Chemical disinfection is one of the more commonly used soil disinfection methods at present, but almost all chemical agents will pollute the air, water, soil and crops more or less when used in large quantities for a long time, endangering human health and not conducive to the sustainable development of agriculture develop

Physical disinfection methods mainly include high-temperature method, solar method, microwave sterilization method, soil electrochemical treatment sterilization method, etc., but these methods mostly rely on the research and development of new technologies and high-cost equipment investment, which is not conducive to the popularization of technology and large-scale application
