Method for preparing microorganism-decomposing agent used for producing biological organic fertilizer by livestock and poultry manure fermentation

Abstract

The invention belongs to preparation for microorganism-decomposing agents, and in particular discloses a method for preparing a microorganism-decomposing agent used for producing a biological organic fertilizer by livestock and poultry manure fermentation. The method comprises the following steps of: respectively inoculating Saccharomyces cerevisiae AS1.2414 and Saccharomyces cerevisiae AS1.1854 into a culture medium which contains a carbon source, a nitrogen source and nutrient substances for fermentation; inoculating Rhodopseudomonas palustris AS 1.2349 into a culture medium which contains nutrient substances for fermentation; and mixing saccharomyces cerevisiae fermentation liquor, rhodopseudomonas palustris fermentation liquor and rhodopseudomonas palustris fermentation liquor according to a volume ratio of 50:25:25, and taking a mixture of rice bran and bran as a carrier to adsorb the mixed fermentation liquor so as to prepare a solid decomposing agent. The method solves the problems of the quality and the speed of composting influenced by the relatively low composting speed in the composting process of the prior art, and has the advantages of effectively reducing the composting time, improving the compost maturity and the production efficiency, and the like.

Description

technical field [0001] The invention belongs to the preparation of a microbial decomposing agent, in particular to a preparation method of a microbial decomposing agent used for fermenting livestock and poultry manure to produce bio-organic fertilizer. Background technique [0002] With the rapid development of my country's animal husbandry industry, a large number of livestock and poultry waste has also increased sharply. The country produces about 2.7 billion tons of livestock and poultry manure every year. Livestock and poultry manure is rich in nutrients needed by crops, but it also contains a lot of heavy metals , pest eggs and other harmful substances, so they cannot be directly used. Composting treatment is a harmless treatment method commonly used. The stability and maturity of compost are important basis for evaluating the quality and safe use of compost, but there is no The more effective special compost decomposing agent leads to a slower decomposing speed during th...

Livestock and poultry manure is rich in nutrients needed by crops, but it also contains a lot of heavy metals , pest eggs and other harmful substances, so they cannot be directly used. Composting treatment is a harmless treatment method commonly used. The stability and maturity of compost are important basis for evaluating the quality and safe use of compost, but there is no The more effective special compost decomposing agent leads to a slower decomposing speed during the composting process, which affects the quality and speed of compost decomposing
