Compound microbes for reducing and disinfecting greenhouse soil and soil disinfection method

Abstract

The invention relates to the greenhouse crop planting field, in particular to compound microbes for reducing and disinfecting greenhouse soil and a soil disinfection method, and solves the problem of multiple defects in the prior art. The compound microbes comprise bacteria, actinomycetes, saccharomycetes and moulds. The soil disinfection method includes the steps of selecting June to September as a disinfection period to apply crop straws, organic fertilizer and the compound microbes on the soil after the crops are harvested; deeply plowing soil layers to form small ridges; covering ridge surfaces with plastic film, filling enough water under the film till the soil humidity achieves 100%, and sealing the mulching film and covering the greenhouse plastic film for 20 to 25 days; and uncovering the greenhouse plastic film and removing the mulching film for planting. According to the compound microbes for reducing and disinfecting greenhouse soil and the soil disinfection method, the method is non-toxic, harmless, pollution-free and residue-free, pathogenic bacteria, ova and the like in soil plough layers are killed, soil organics are increased, the soil physical and chemical structure is improved, soil fertility is improved, and good foundation is laid for improving product qualities.

Description

technical field [0001] The invention relates to the field of growing crops in greenhouses, in particular to a greenhouse and greenhouse soil reduction and disinfection composite microbial agent and soil disinfection method. Background technique [0002] In recent years, with the popularization and promotion of protected cultivation, the production area of ​​protected areas has continued to increase, especially the greenhouse cultivation in the production of vegetables, melons and other plants has developed rapidly, and the multiple cropping index has reached more than 200%. The utilization rate of land is getting higher and higher, which provides conditions for increasing farmers' income and productivity. However, the temperature and humidity under the greenhouse conditions are very conducive to the growth and spread of diseases and insect pests, especially soil-borne diseases and insect pests. In addition, due to continuous cropping, various pathogenic bacteria in the s...
