Embodiment Construction

[0018] In conjunction with the accompanying drawings, the preferred technical solution of the present invention to solve the technical difficulties such as long production cycle of traditional compost, low compost maturity, difficult operation in low temperature environment and poor product quality will be further explained:

[0019] The composite bacterial agent of the present invention mainly includes several ready-made strains of Trichoderma reesei, Aspergillus oryzae, Bacillus subtilis and Mucor, and strains are blended in different proportions by weight, and the ratio of blending is 1:1:1:1, 1:1:2:2, 2:2:1:1, etc., add the prepared compound bacterial agent to the aerobic composting pile of livestock and poultry manure and corn straw shavings, and follow the traditional aerobic composting operation process. .

[0020] The main operating process of the present invention is:

[0021] Chop the corn stalks to a length of 2-3cm, remove the impurities in the manure of livestock...

Abstract

The invention mainly relates to preparation and application of complex microbial inoculants, and is mainly applied to research of technologies of quick fermentation, low-temperature-resistant running and nutrient loss of aerobic composting. The preparation is started from weak links of technological research of a composting technology of the livestock and poultry excrement, development of compost microbial agents serves as a sally port, preparation and application of exogenous microbial agents in a composting technology are deeply researched through a scientific research means, actual scientific achievements are obtained, and efficient complex microbial inoculants suitable for composting of the livestock and poultry excrement are obtained finally. By the complex microbial inoculants, a livestock excrement composting process can be optimized, composting efficiency is improved, and ripe composting degree and quality of composting products are improved; and particularly, the complex microbial inoculants can still function in a low-temperature environment at the temperature below 20 DEG C.

Description

technical field [0001] The invention relates to the preparation of a high-efficiency and fast-fermenting livestock and poultry feces aerobic composting composite bacterial agent, which is mainly used in the research of rapid fermentation of aerobic composting, anti-low temperature operation and nutrient loss technology, and belongs to the field of agricultural bio-organic fertilizers. Background technique [0002] At present, the comprehensive production capacity of my country's livestock and poultry breeding industry has been greatly improved, the supply of products is sufficient, and the annual output continues to rise. With the rapid development of intensive breeding mode, the concentrated production of livestock and poultry waste is also increasing, polluting air and water bodies, causing environmental degradation, and occupying a large amount of land, resulting in waste of land resources. Obviously, the increase of breeding scale is positively correlated with the amount...
