Application of microbial preparation for quickly decomposing cattle faeces

Abstract

The invention discloses a microbial preparation of quickly decomposing cattle faeces as well as a preparation method and an application of the microbial preparation, and relates to a microbial preparation capable of decomposing cattle faeces as well as a preparation method and application of the microbial preparation. The invention aims to solve the problem that in the existing decomposing and fermenting process of cattle faeces, the manure is quick to warm, the degradative rate for cellulose is low, the decomposing degree is not high and the fermenting period is long. The microbial preparation is prepared from long thorned chaetomium, trichoderma koningii, chaetomium torulosum Bainier, Trichoderma viride and cryytococcus neoformans. The preparation method comprises the following steps: I, inoculating a strain on a culture medium; II, preparing a skimmed milk emulsion, inoculating after sterilization and producing a leavening agent on a table; III, carrying out quick freezing on the leavening agent and freezing and drying to obtain the freeze-drying culture powder; and IV, proportioning the freeze-drying culture powder according to weight part to prepare the microbial preparation after uniformly mixing. By fermenting cattle faeces with the microbial preparation, the microbial preparation is quick to warm, and can improve the degree of cellulose degradation and the degree of decomposition of organic fertilizer products and shorten the fermenting period.

Description

technical field

[0001] The invention relates to a microbial preparation capable of decomposing beef cattle manure, a preparation method and application thereof. Background technique

[0002] In recent years, my country's beef cattle breeding industry has developed rapidly, but a large amount of feces and sewage have been produced, which not only affects the sustainable development of related industries, but also causes serious rural environmental pollution and endangers human health. At present, domestic and foreign manure treatment methods tend to produce organic fertilizers, and the main processes include direct drying, natural composting and microbial inoculant fermentation. Cow dung contains 14.5% organic matter, nitrogen (N) 0.30-0.45%, phosphorus (P 2 o 5 )0.15-0.25%, potassium (K 2 O) 0.10-0.15%. Compared with other livestock, the organic matter and nutrient content in cow dung is the lowest among all kinds of livestock. At the same time, the texture is fine and de...
