Complex bacteria inoculant for preparing organic fertilizer from effluents of animal slaughter houses and breeding plants serving as raw materials and preparation method thereof

Abstract

The invention provides a complex bacteria inoculant for preparing an organic fertilizer from effluents of animal slaughter houses and breeding plants serving as raw materials, which has the advantages of effectively deodorizing and enhancing the fertility, and a preparation method thereof. The complex bacteria liquid inoculant is prepared by the following steps of: independently performing liquidfermentation on each single bacterium, namely A, lactobacillus fermentium, B, bacillus laterosporus, C, trichoderma koningii, D, nitrogen-fixing bacteria spores and E, bacillus mucilaginosus; and mixing the bacteria, wherein the final product comprises the living bacteria (including living spores) in percentage by weight: 20 to 50 percent of A, 20 to 50 percent of B, 0 to 20 percent of C, 0 to 20percent of D and 0 to 20 percent E. The liquid inoculant is further processed so as to obtain solid inoculant. The complex inoculant of the invention is specially used for preparing the organic fertilizer from excrements of pig farms (or chicken farms) and wastes of slaughter houses thereof, which serve as basic raw materials, and a small amount of straws, and has an obvious effect of reducing odor of the fertilizer and the field. The complex inoculant combines the functions of improving the disease resistance of plants, promoting growth and improving soil and the fertility of the fertilizer.

Description

technical field [0001] The invention belongs to the application field of agricultural microorganisms, in particular to the professional scope of microbial organic fertilizers. technical background [0002] The extensive use of chemical fertilizers in the agricultural field has seriously damaged human life and the ecological environment. Due to the residue of drugs and the deterioration of soil structure, agriculture has fallen into a serious ecological crisis. Modern biotechnology and biological control technology, with agricultural microbial technology as an important aspect, are effective and important measures to deal with the above crisis, and are also one of the important trends of modern agriculture. [0003] Over the past half a century, especially in the past two decades, in the field of biotechnology, the application of nitrogen-fixing bacteria, phosphorus-solubilizing bacteria, potassium-solubilizing bacteria, and photosynthetic bacteria in agriculture has also ma...

AI Technical Summary

Problems solved by technology

However, the research on the development of bacterial fertilizers that are suitable for specific soil conditions, specific fermentation raw materials, and have specific effects on specialized crops is far from meeting the production requirements.

[0005] There are also many studies on the production of microbial organic fertilizers using animal slaughterhouse and farm effluents as raw materials for the production of bacterial fertilizers, but it is still difficult to achieve ideal results, especially in reducing odor and improving fertility.
