Embodiment 1

[0024] Such as figure 1 Shown, a kind of preparation method of the composting compound fermentation bacterial agent that promotes putrefaction, this method uses native bacteria, Bacillus stearothermophilus (Bacillus stearothermophilus) respectively, wherein this strain of Bacillus stearothermophilus is purchased from China Ordinary Microorganisms Preservation Management Center , the deposit number is CGMCC1.1866, after the following cultivation steps:

[0025] The first step: the solid indigenous bacterial agent is obtained through the collection and expansion of indigenous bacteria;

[0026] The second step: making the solid bacterial agent of Bacillus stearothermophilus through the solid slant culture of Bacillus stearothermophilus, expanded culture, and aerated culture in a fermenter;

[0027] The third step: mixing the solid indigenous bacterial agent prepared above with the solid bacterial agent of Bacillus stearothermophilus in a weight ratio of 2:1 to prepare a composi...

Embodiment 2

[0034] Such as figure 1 Shown, a kind of preparation method of promoting putrefaction composting compound fermentation bacterial agent, this method uses native bacterium, thermophilic Bacillus stearothermophilus (Bacillus stearothermophilus) respectively, through following cultivation steps:

[0035] The first step: the solid indigenous bacterial agent is obtained through the collection and expansion of indigenous bacteria;

[0036] The second step: making the solid bacterial agent of Bacillus stearothermophilus through the solid slant culture of Bacillus stearothermophilus, expanded culture, and aerated culture in a fermenter;

[0037]The third step: mixing the solid indigenous bacterial agent prepared above with the solid bacterial agent of Bacillus stearothermophilus in a weight ratio of 3:1 to prepare a composite fermentation bacterial agent for promoting decay and composting.

[0038] The collection of the native bacteria is to take 2.5kg of raw rice and put it into a cl...

Embodiment 3

[0044] Such as figure 1 Shown, a kind of preparation method of promoting putrefaction composting compound fermentation bacterial agent, this method uses native bacterium, thermophilic Bacillus stearothermophilus (Bacillus stearothermophilus) respectively, through following cultivation steps:

[0045] The first step: the solid indigenous bacterial agent is obtained through the collection and expansion of indigenous bacteria;

Abstract

The invention relates to a preparing method of microbial inoculants and discloses a preparing method of decomposition promoting and composting compound fermentation inoculants. The preparing method of decomposition promoting and composting compound fermentation inoculants includes: collecting indigenous bacteria, culturing the indigenous bacteria in enlarge cultivation mode, culturing the solid inclined surface of bacillus stearothermophilus, culturing the bacillus stearothermophilus in enlarge cultivation mode, culturing the bacillus stearothermophilus in a fermentation tank in aerobic culture mode, mixing the obtained solid indigenous bacteria inoculants and the obtained bacillus stearothermophilus solid inoculants in weight percent of (2-3):1 to prepare the decomposition promoting and composting compound fermentation inoculants. The obtained decomposition promoting and composting compound fermentation inoculants are fertilized in composting substrate at the early stage, can fast improve pile temperature and reduce pile PH value, shortens pile fermentation earlier-stage time, promotes substrate microorganism movement, leads composts to enter the high temperature stage in the shortest time, achieves fast thorough decomposition through thermophilic bacteria movement and oxygen filling in stacked piles, and accordingly improves composting quality.

Description

technical field [0001] The invention relates to a preparation method of a microbial bacterial agent, in particular to a preparation method of a decay-promoting composting compound fermentation bacterial agent. Background technique [0002] With the development of industry and agriculture, the amount of urban sludge, garbage, and livestock and poultry manure is increasing day by day, and some solid wastes seriously endanger the ecological environment and human health. However, from the perspective of resource utilization, these solid wastes are mainly organic matter, and contain a certain amount of nutrients such as nitrogen, phosphorus, potassium, calcium, magnesium, sulfur and various trace elements. After treatment, they can become good agricultural fertilizers. . Since composting is a biological process, the microbial populations that play a key role in the degradation of organic matter are different at different stages of the composting process, and the various paramete...
