Soil disinfecting method

Abstract

The invention provides a soil disinfecting method, which uses micro-nano bubble ozone water with the ozone concentration of 70-10 mg / L for spraying soil for disinfection and disinfects the soil by combining an ozone sterilization technology with a micro-nano bubble technology. According to the soil disinfecting method, ozone is produced by an ozone generator, the ozone is quickly dissolved into water through a micro-nano bubble generating device, and the soil to be treated is sprayed or irrigated so as to kill harmful pathogenic microorganisms in the soil, thus achieving an aim of disinfecting the soil. By the soil disinfecting method, soil-borne diseases are effectively prevented and treated, pesticide residues are avoided, and a standard for green production of crops is met.

Description

technical field [0001] The invention belongs to the field of prevention and control of agricultural production diseases and insect pests, and in particular relates to a soil disinfection method. Background technique [0002] With the promotion of green agricultural production, the safety of agricultural production has attracted more and more attention. Crop diseases and insect pests are the main hazards in agricultural production. Due to diseases and insect pests, crops can be greatly reduced in production and quality. In recent years, the occurrence area of ​​pests and diseases in my country has been increasing, and pests and diseases have become the main restrictive factors for the development of high-yield, high-quality, and efficient agriculture in China. [0003] Soil is the main medium for the transmission of root-borne diseases and the main place for the reproduction of diseases and insect pests. Many germs, insect eggs and pests live or overwinter in the soil, and ...

AI Technical Summary

Problems solved by technology

This method is likely to cause chemical residues in the soil, leading to environmental pollution, leaving potential safety hazards, which is not conducive to the health of humans and animals, and seriously reduces the yield and quality of food crops and vegetables.

However, the use of physical methods such as high-temperature steam and high-temperature hot water for soil disinfection has problems such as low efficiency and high cost.
