Method for producing microbial fertilizer by utilizing kitchen waste

Abstract

The invention provides a method for producing a microbial fertilizer by using kitchen waste. The microbial fertilizer contains one selected from the group consisting of Bacillus amyloliquefaciens, Bacillus licheniformis, Bacillus mucilaginosus, Bacillus megatherium, Brevibacillus laterosporus, Bacillus thuringiensis, Bacillus subtilis and Streptomyces microflavus or mixed bacteria of two or more selected from the group. The method for producing the microbial fertilizer comprises the following steps: removing foreign matters in the kitchen waste, heating the kitchen waste, taking out grease, crushing the rest kitchen waste, adding enzyme for enzymolysis, putting the kitchen waste having undergone enzymolysis into a fermentation tank, performing sterilizing, inoculating one or more culturedstrains, performing fermenting with a pure bacterium or mixed bacteria to obtain a single-bacterium liquid microbial fertilizer or a composite-bacteria liquid microbial fertilizer, and adsorbing the liquid bacterial fertilizer with a carrier to obtain the solid microbial fertilizer. The microbial fertilizer is produced by utilizing the kitchen waste, so production cost is remarkably reduced, and the pollution of the kitchen waste to the environment can be effectively reduced.

Description

Technical field

[0001] The invention belongs to the field of biological technology, and relates to a method for producing microbial fertilizer by using kitchen waste. Background technique

[0002] Due to the improvement of water activity, people pay more and more attention to green food. Microbial fertilizer has the functions of improving soil fertility, improving soil structure, stimulating crop growth, and enhancing crop resistance. It is a very promising green fertilizer. One of the main reasons currently restricting the widespread use of microbial fertilizers is the high production cost, which is more expensive than general telephone charges or farmyard manure. Since the production of microbial fertilizers basically uses industrial products such as glucose, sucrose, peptone, and yeast extract as the main medium raw materials, the production cost is high and the price is difficult to reduce. How to effectively replace the existing raw materials for microbial fertilizer produ...
