Pig-chicken excrement fermenting compound bacteria, preparation method and method of utilizing compound bacteria to ferment and prepare organic fertilizer

Abstract

The invention discloses pig-chicken excrement fermenting compound bacteria, a preparation method and a method of utilizing the compound bacteria to ferment and prepare an organic fertilizer. The fermenting compound bacteria comprise the following raw material bacteria: bacillus subtilis, bacillus licheniformis, bacillus coagulans, bacillus megatherium and trichoderma viride. The method for preparing the organic fertilizer comprises the following steps: mixing pig-chicken excrement with crushed straws, adding the fermenting compound bacteria to the mixture according to a dosage of 1-2 Kg per ton, mixing uniformly, the moisture being 50-65 wt%, stacking the mixed raw materials, keeping the temperature at 55-65 DEG C to conduct fermentation, two days after the fermentation, turning the stacked materials for the first time, and then turning the materials once every one or two days, keeping the moisture at 50-65 wt% during the fermentation phase, and after fermentation, obtaining the organic fertilizer with a moisture content of 20-30 wt%. The pig-chicken excrement fermenting compound bacteria disclosed by the invention can be used for fermenting the pig and chicken excrement; compared to the prior art, the method for preparing the organic fertilizer is low in productive investment and production cost, convenient to use, free of odor, and good in the fermentation and decomposing effect.

Description

technical field [0001] The invention relates to the technical field of microbial fermentation, in particular to a compound bacterium for fermenting pig and chicken manure to prepare organic fertilizer and its fermentation technology. Background technique [0002] Pig (chicken) manure should be a good farmyard manure and a high-quality organic fertilizer resource for fertilizing and improving soil. However, if fresh pig (chicken) manure is directly applied, negative effects such as crop root damage, burnt seedlings, disease, and weed damage will inevitably occur. If according to the existing natural stacking and retting fermentation treatment, there are the following disadvantages: one is that the stacking retting time is long (4-6 months), and the effect is poor; the other is that long-term stacking not only occupies the site, but also pollutes the surrounding environment; The third is that the fermented feces of natural composting and retting are rotten and wet, have a hug...
