Animal and plant waste decomposition complex microbial inoculant and bio-organic fertilizer prepared from same

Abstract

The invention discloses an animal and plant waste decomposition complex microbial inoculant and a bio-organic fertilizer prepared from the same, and belongs to the field of bio-organic fertilizers. The microbial inoculant comprises bacillus subtilis, lactic acid bacteria, saccharomyces cerevisiae, trichoderma reesei and aspergillus niger, and by adding the microbial inoculant into animal and plantwaste decomposition fermentation, decomposition of the organic fertilizer can be accelerated, and the fermentation time can be shortened. The animal and plant waste decomposition complex microbial inoculant disclosed by the invention can be quickly propagated in decomposition production activities of the organic fertilizers, so that cellulose, protein and other substances in animal and plant wastes are degraded and decomposed, harmful substances are absorbed or decomposed, odor substances are absorbed or neutralized to achieve a deodorization effect, a certain biological prevention and control function is achieved, and soil physicochemical properties are improved.

Description

technical field [0001] The invention belongs to the field of bio-organic fertilizers, and in particular relates to a compound microbial agent for decomposing animal and plant wastes, a preparation and use method thereof, and a bio-organic fertilizer prepared therefrom. Background technique [0002] With the extensive use of chemical fertilizers, it is a well-known fact that their utilization rate has been continuously reduced. This shows that it is limited to increase crop yield only by increasing the application of chemical fertilizers in large quantities, not to mention a series of problems such as environmental pollution. For this reason, scientists from various countries have been working hard to explore ways to improve the utilization rate of chemical fertilizers to achieve balanced fertilization and rational fertilization to overcome its drawbacks. Microbial fertilizers have a unique role in solving this problem. Therefore, according to the types of crops and soil co...

Problems solved by technology

[0004] At present, domestic microbial agents are developing rapidly, and there are more and more types of bacterial fertilizers on the market. The active bacteria contained in them are different. It is not clear whether there is mutual inhibition between them. If they inhibit each other, the fertilizer efficiency will be reduced.
