Soil disinfectant and soil disinfecting and sterilizing method

Abstract

The invention belongs to the field of agriculture, and specifically provides a soil disinfectant, which consists of a solution A and a solution B, and is characterized in that: the solution A contains a hydrogen peroxide decomposition catalyst; and the solution B contains hydrogen peroxide. The invention further provides a soil disinfecting method. The method comprises the following steps of: (1) adding the solution A into soil to be disinfected; and (2) adding the solution B into the soil to be disinfected after the solution A permeates into the soil. As proved by an experiment result, the solution A reacts with the solution B rapidly after contacting for decomposing oxygen and heating, the generated heat is used for heating soil to 70-150 DEG C and sterilizing bacteria and eggs in the soil, degradation of pesticides can be facilitated, and lands containing plenty of trace elements are provided; and the soil disinfectant is safe, reliable and environment-friendly.

Description

technical field

[0001] The invention belongs to the field of agriculture, and in particular relates to a method for disinfecting and sterilizing soil. Background technique

[0002] In the field of agricultural cultivation, bacteria, ground insect pests and pesticide residues are problems that seriously restrict sustainable production, often leading to crop diseases, reducing yield and quality, and causing heavy losses to farmers. For example, around the beginning of March in spring, it is very difficult to plant in the Guangdong area. The reason is that if the seedlings are planted at this time, they will be destroyed by dog ​​lice, and dog lice are caused by the underground eggs hatching in spring, so they will damage the crops. Seedlings are harmful. A large amount of pesticide residues affects food safety and also destroys the balance of the natural environment.
