Fecal deodorizing microorganism combining bacteria and method for producing organic fertilizer using same

Abstract

The invention discloses fecal deodorizing microorganism combining bacteria and a method for producing an organic fertilizer using same. The combining bacteria comprise the following components: Mucor circinelloides (Mucor Circinelloides), Bacillus pumilus (Bacillus Pumilus), and Stenotrophomonas maltophilia (Stenotrophomonas maltophilia), the number ratio of which is 1:0.9-1.2:0.9-1.2. The manure and straws are used as raw materials, and the microorganism combining bacteria are fermented to produce the organic fertilizer. In the process of producing the organic fertilizer by the method, the odor generation can be obviously reduced in the compositing process, and the method has simple process, low cost and easy promotion.

Description

technical field [0001] The invention relates to the technical field of using combined bacteria to produce organic fertilizers, in particular to a feces deodorizing microbial combined bacteria and a method for producing organic fertilizers. Background technique [0002] With the increasing market demand for livestock and poultry products, large-scale and intensive farms have developed rapidly. According to relevant statistics, China's large-scale pig farms with more than 500 pigs annually account for 7.7% of the total pig farms, and broiler and laying hen farms with an annual stock of 2,000 pigs account for 48% and 44% of the total pig farms respectively. The proportion of intensive breeding industry in the total agricultural output value is increasing, and the livestock and poultry waste it discharges is also increasing. According to the survey conducted by the State Environmental Protection Administration in 2000 on 23 provinces and cities with concentrated large-scale bree...

Problems solved by technology

Composting is an effective way to deal with the recycling, reduction, and harmless utilization of livestock and poultry manure, but the traditional composting treatment method mainly uses the indigenous microorganisms in the composting raw materials to degrade organic pollutants, and the number of indigenous microorganisms in the initial stage of composting It takes a certain amount of time to reproduce, and the decomposition speed of various microorganisms is very different. Therefore, traditional compost often has problems such as long fermentation time, odor and low fertilizer efficiency.
