Abstract

The invention discloses a composite leavening agent for organic material composting. The composite leavening agent comprises the following raw materials in parts by weight: 1-1.5 parts of a mixed microbial agent and 0.5-1 part of a combined enzyme agent, wherein the mixed microbial agent is a mixture of bacillus cereus, bacillus subtilis, bacillus licheniformis, bacillus megatherium, bacillus circulans, bacillus sphaericus, trichoderma viride, trichoderma reesei and aspergillus niger, and the combined enzyme agent is a mixture of protease, cellulase, glucanase and pectinase. The composite leavening agent can quickly start fermentation, prolong the high-temperature period of compost and accelerate the decomposition speed of organic fertilizer, so the quality of the fertilizer is improved, production cost is reduced, and the problem of pollution of organic wastes is solved.

Description

technical field

[0001] The invention belongs to the technical field of resource utilization, and in particular relates to a composite starter for composting organic materials. Background technique

[0002] The production of organic fertilizer through composting technology can not only treat organic waste such as livestock and poultry manure and domestic garbage, and turn waste into treasure, but also improve the quality of agricultural products, reduce the amount of chemical fertilizer used, improve the soil environment, and reduce environmental pollution.

[0003] Composting technology usually uses specific functional microorganisms to be added to the organic materials to be composted to promote the transformation of organic matter into stable humus under artificial control conditions. This method can increase the nitrogen content of the compost, promote the rapid heating of the compost body, and accelerate the degradation of organic matter, thereby shortening the compost m...

Examples

Embodiment 1

[0024] A composite fermenting agent used for composting organic materials, the raw material components and weight ratios include: 1.5 for microbial mixed bacteria agent and 0.5 for combined enzyme agent. The mixed microorganism agent is a mixture of Bacillus cereus, Bacillus subtilis, Bacillus licheniformis, Bacillus megaterium, Bacillus circulans, Bacillus sphaericus, Trichoderma viride, Trichoderma reesei, Aspergillus niger, between them The weight ratio is the same. The combined enzyme agent is a mixture of 5000U / g protease, 1000U / g cellulase, 3000U / g dextranase, 2000U / g pectinase and 5000U / g lipase. Then mix the microbial mixed bacterial agent and the combined enzyme agent which have been mixed separately to compound the finished product. When used in the decomposition of organic raw materials, the inoculum amount of each bacteria is 0.2% of the weight of the organic raw materials, and the combined enzyme agent is 0.5-1.5%.

Embodiment 2

[0026] The difference with Example 1 is:

[0027] The raw material components and weight ratios of the composite fermentation agent include: 1.2 for the mixed microbial agent and 0.6 for the combined enzyme agent. The combined enzyme agent is a mixture of 4000U / g protease, 2000U / g cellulase, 5000U / g dextranase, 3000U / g pectinase, 7000U / g lipase, and then the mixed microorganisms Agent and combined enzyme agent are mixed to compound the finished product.

Embodiment 3

[0029] The difference with Example 1 is:

[0030] The raw material components and weight ratios of the composite fermentation agent include: 1.5 for the mixed microorganism agent and 0.7 for the combined enzyme agent. The inoculum amount of each strain in the described microbial mixed bacterial agent is 0.3% of organic raw material weight, and described combined enzyme agent is 5000U / g protease, 2000U / g cellulase, 4000U / g dextranase, 3000U / g The mixture of g pectinase and 8000U / g lipase, and then mix the separately mixed microbial mixed bacterial agent and combined enzyme agent to compound the finished product.

[0031] The compound fermentation agent for organic material composting provided by the invention is suitable for composting and fermentation of most organic wastes such as livestock and poultry manure and crop stalks. The specific method of use is to crush and mix the organic waste evenly, adjust the moisture content, add a compound starter, stir evenly, and transpor...
