Soil disinfection and soil restoration method

Abstract

The invention discloses a soil disinfection and soil restoration method. The method comprises the following steps: deep ploughing soil, wherein the ploughing depth is 0.2-0.5m; disinfecting the soil with a soil disinfectant, wherein the consumption of the soil disinfectant is 1-2kg per mu; and restoring the soil with a soil restoration agent, wherein the consumption of the soil restoration agent is 10-30kg per mu. According to the soil disinfection and soil restoration method provided by the invention, soil disinfection and soil restoration can be simultaneously realized, and the microecological environment of the soil is improved, so that the fertility of the soil is increased, disease and pest attacks are resisted, and the consumption of pesticide is reduced, thereby being beneficial to environmental protection.

Description

technical field

[0001] The invention belongs to the field of agricultural biotechnology, and in particular relates to a soil disinfection and soil restoration method. Background technique

[0002] In agricultural production, the soil contains fungi, bacteria, nematodes, weeds, soil-borne viruses, underground pests, etc. that harm the growth of crops, resulting in a large area of ​​crop production reduction. Soil disinfection is a phenomenon in which chemical pesticides are applied to the soil to kill germs, nematodes and other harmful organisms. It is usually carried out before the crops are sown. In addition to the application of chemical pesticides, soil disinfection can also be performed using dry heat or steam. The main methods are spraying or watering, poisonous soil and fumigation. Although these methods can effectively kill soil diseases and insect pests, they cause pesticide pollution and damage to the ecological environment to the soil, which is unsustainable. ...
