Straw returning biological agent for greenhouse crops and biological fermentation method

Abstract

The invention discloses a straw returning biological agent for greenhouse crops and a biological fermentation method. The biological fermentation method comprises the steps: applying a compound microbial agent into a greenhouse, uniformly mixing the compound microbial agent with soil, smashed straws and manure, irrigating the greenhouse with enough water, and sealing the greenhouse for fermentation. The microbial agent enables organic matters and organic fertilizer in the soil and the straws to be quickly fermented, rotted and decomposed, and can quickly kill pests and diseases in the straws and the soil plough layer and quickly increase the content of organic matters and the fertility of the soil; heat generated by rotting fermentation of the organic manure and the straws and heat energy supplied by sunlight under a condition that the greenhouse is sealed can quickly heat the soil to create a high-temperature wet soil environment and enable the temperature in the greenhouse to reach 70 to 80 DEG C; the high temperature in the greenhouse is conducted into the soil to enable the soil temperature in the greenhouse to reach 45 to 60 DEG C; and the high temperature in the greenhouse can kill the pests and the diseases which float in the air and are attached to a wall and a material such as a plastic thin film.

Description

technical field [0001] The invention relates to a compound microbial bacterial agent used for in-situ fermentation of waste vegetable stalks and organic manure in a greenhouse, and also relates to a biological fermentation method based on the biological bacterial agent. Background technique [0002] In recent years, with the popularization and development of protected cultivation, the area of ​​greenhouses has been increasing continuously, and it has become an important mode of vegetable cultivation in my country, which has resulted in a large amount of vegetable straw waste. Vegetable straw waste is a good organic fertilizer. According to incomplete statistics, the national vegetable straw waste is as high as 150 million tons per year. [0003] When you go to the greenhouse vegetable production area, you will see discarded vegetable stalks in the field, in front of the shed, on the roadside, in the ditches, etc. After long-term stacking, the discarded vegetable stalks will...

[0003] When you go to the greenhouse vegetable production area, you will see discarded vegetable stalks in the field, in front of the shed, on the roadside, in the ditches, etc. After long-term stacking, the discarded vegetable stalks will not only seriously hinder traffic and block rivers serious fire hazard

Discarded vegetable stalks will cause artificial secondary pollution if they are not properly treated. Once the vegetable stalks are transported out of the shed, they will be mixed w...
