Microbial organic substrate fermenting material and method for manufacturing organic substrate by means of same

Abstract

The invention discloses a microbial organic substrate fermenting material and a method for manufacturing a saw dust microbial organic substrate by means of the same. The fermenting material is composed of saw dust, cow dung and complex microbial inoculants, and the mass ratio of the saw dust to the cow dung is 5:1. One kilogram of complex microbial inoculants is added to every cubic meter of mixtures of the saw dust and the cow dung. The method for manufacturing the saw dust microbial organic substrate comprises the following steps that the fermenting material is prepared; aerobic fermentation and heap building fermentation are carried out; fermentation time is controlled; humidity is adjusted; fermentation management is carried out. The complex microbial fermentation inoculants are adopted, sustaining putrefaction decomposition is carried out on the saw dust substrate, the residue rate of the saw dust is reduced, and the fertilizer efficiency level of the saw dust is improved. Meanwhile, nitrogen fixation and phosphorus fixation are carried out, and the organic content of soil is improved. The disease and pest resisting capacity of plants is improved, root diseases are avoided, the problems of root-knot nematode, root rot and the like are solved, and photosynthesis can be promoted.

Description

technical field [0001] The invention relates to the field of microbial fermentation, in particular to a microbial organic substrate fermentation raw material and a method for making an organic substrate using the fermentation raw material. Background technique [0002] The safety of agricultural products and the sustainable development of agriculture are prominent issues facing the world, and all countries are increasing policy legislation and investment in capital and technology to deal with them. Excessive use of chemical fertilizers and pesticides has led to soil compaction, reduced fertility, and reduced quality and safety of agricultural products. The wood processing industry has become one of the fastest-growing and promising manufacturing industries in the country, and its growth rate greatly exceeds the average level of the entire manufacturing industry. According to statistics, from 2001 to 2010, the average annual growth rate of the output value of the wood proces...
