Description

A deep soil disinfection device and disinfection method

technical field

The invention relates to the technical field of soil disinfection and improvement, in particular to a deep soil disinfection device and a disinfection method.

Background technique

Soil disinfection is a very important link in agricultural production. Most of the soil disinfection is chemical pesticides or biological pesticides for soil disinfection treatment. These soil disinfections more or less pollute the soil and the surrounding environment, and at the same time bring a certain degree of safety hazard to the safety of agricultural products. Some soil disinfection is carried out by physical methods, such as ultraviolet disinfection, soil steam disinfection and so on. Ultraviolet disinfection and the like cannot be carried out on a large area of soil, and the disinfection effect is not ideal. Soil steam disinfection, as disclosed by the applicant with the publication number CN104509245A, is a soil improvement method for abandoned ginseng land, which includes steam disinfection of the soil to be disinfected. Although it is a non-toxic, safe and thorough soil disinfection technology, it can The high temperature of high-pressure steam is used as a means of sterilization and insecticide, and water is used as a medium. However, it takes a lot of energy to convert water into steam in the disinfection process.
