AI Technical Summary

Problems solved by technology

Because chickens have a short digestive tract and a special excretion mode of combining feces and urine, resulting in thick excrement, rich nutrients, and high nitrogen content, some studies have shown that NH in chicken manure fermentation liquid 4 + -N is 15 times that of cow manure, 4 times that of pig manure, and the inherent flora in chicken manure is also different from that of other livestock manures, and there is no high-efficiency compound microorganism for reducing ammonia release during chicken manure composting fermentation Bacteria

Embodiment 1

[0023] Example 1 Domestication, isolation, purification, screening and identification of Pantoea agglomerans HAAS-1, anaerobic bacillus nubihalogenes HAAS-2 and Enterobacter aerogenes HAAS-3

[0024] 1. Domestication, isolation and purification of strains

[0025] 1. Domestication of strains

[0026] In a large-scale chicken farm in Jiangxia District, Wuhan City, which has harmless treatment equipment for chicken manure trough composting, 50ml of fresh chicken manure and fermented materials in different composting periods (heating period, high temperature period and decomposing period) were collected. After mixing the samples, take 30ml and place them in a closed environment with high ammonia gas concentration to acclimatize the microorganisms in the samples, and the acclimatization period is 15 days. During the acclimatization process, the samples were turned daily, and the humidity of the samples was maintained by water addition.

Abstract

The invention provides a compound microbial agent for reducing ammonia gas release in chicken manure composting and a preparation method and application thereof, and belongs to the technical field ofmicroorganisms. The compound microbial agent consists of Pantoea agglomerans HAAS-1, Anoxybacillus rupiensis HAAS-2 and Enterobacter aerogenes HAAS-3. The compound microbial agent can effectively reduce the ammonia gas yield in the chicken manure composting process, and when the compound microbial agent is added in an amount of 2.5% of the composting material weight, the total release amount of ammonia gas can be reduced by 65% or above in the first 15 days of composting fermentation; and the compound microbial agent is used for ammonia gas removal of the chicken manure compost, and is simpleto use, low in cost and free from secondary pollution.

Description

technical field [0001] The invention belongs to the technical field of microorganisms, and in particular relates to a composite microbial bacterial agent for reducing the ammonia gas produced in chicken manure composting and a preparation method thereof. Background technique [0002] With the continuous improvement of the scale and facilities of my country's animal husbandry, the scale of livestock and poultry breeding has gradually expanded. Therefore, the centralized treatment and resource utilization of livestock and poultry manure has become a problem faced by livestock and poultry farming. During the aerobic composting of livestock and poultry manure, a large amount of odor is produced, which affects the life and health of the surrounding residents. It is currently a hot spot of complaints from livestock breeding enterprises. Because the physiological structure of birds is different from that of mammals, they have the characteristics of short digestive tract, low utiliz...
