Echelon circulation inoculation temperature-control compost method

Abstract

The invention relates to a method of temperature controlled compost for echelon circulation inoculation. Among three different stages in the composting process, three different degradation facilitating microbial inocula are added respectively according to composting temperature. In each stage of fermentation and compost, a part of raw materials are taken out to serve as the functional microbial inoculum which is used as composting inoculation next time. Since a new microbial inoculum is unnecessary to be inoculated in each fermentation process, compost cost is obviously reduced and circulation inoculation can effectively overcome the antagonism problem between external connection microorganism and indigenous microorganism, thus fully developing the positive effect of the indigenous microorganism and achieving the effect of accomplishing twice the result with half the effort.

Description

1. Technical field [0001] The invention belongs to the technical field of using microbial fermentation to produce natural fertilizers in agricultural science, and in particular relates to a method for inoculating microorganisms in stages and controlling the temperature of the compost used for composting and fermenting agricultural organic waste. 2. Background technology [0002] my country is a large agricultural country, which produces about 5 billion tons of agricultural waste every year, including livestock and poultry manure, crop stalks, township domestic waste, processing industry waste, etc. The random discarding of these organic wastes not only causes serious environmental problems, It is also a huge waste of resources. [0003] Aerobic composting is the most widely used composting method at present. The traditional aerobic composting method mainly utilizes the natural fermentation of indigenous microorganisms in the composting materials. Various microorganisms act a...

Problems solved by technology

[0007] Since the above-mentioned methods all adopt the one-time input method when adding degrading bacteria or enzyme preparations to compost, there are the following disadvantages in composting one-time input of degrading bacteria or enzyme preparations: as adding a single enzyme preparation or single-function bacteria agent is often only beneficial to composting The degradation of a certain type of substance in the material cannot promote the decomposition of other substances in the pile; when the compound bacterial agent mixed with various microorganisms is used in one-time input method, the pertinence is not strong, and the microbial community after inoculation needs to be in different composts. Self-adjustment of the structure in the first stage will lose a lot of beneficial biological resources, and most of the bacteria with fiber degradation function are some high-temperature or medium-temperature fungi and actinomycetes, which often produce some secondary metabolism that restricts the growth of other bacteria product; the compound enzyme solution is inoculated once, and various enzyme systems often cannot play a role under the optimal reaction conditions, which wastes a lot of additive resources

However, these methods require the use of new bacterial agents or enzyme preparations for each batch fermentation, which increases the cost of composting, and the types and timing of adding bacterial agents or enzyme preparations need to be further studied and improved.
