preparation example Construction

[0025] A method for preparing a microbial fermentation composition, specifically: first mix a combined enzyme agent, a microbial mixed bacterial agent, and water according to a required ratio to form a degradation liquid, and then add organic raw materials to the degradation liquid and mix to obtain a mixed material , followed by aerobic fermentation at 25-50°C.

[0026] The temperature of the aerobic fermentation is maintained at 35-45°C.

[0027] During the entire aerobic fermentation process, the air with an oxygen concentration of 10%-20% is continuously introduced from the bottom of the composting reactor.

[0028] The raw material composition of the microbial fermentation composition also includes salt, and the weight ratio of the salt to the organic raw material is 100:1-2;

[0029] The preparation method also includes the step of mixing the salt with the organic raw material according to the required ratio.

[0030] The preparation method also includes a raw material...

Embodiment 1

[0043] A microbial fermentation composition, its raw material composition and weight ratio are: microbial mixed bacterial agent 1, combined enzyme agent 1, organic raw material 100, water 20, salt 1.5, the raw material composition of the microbial mixed bacterial agent is: Bacillus subtilis Bacillus, Bacillus megaterium, Bacillus jelly-like, Bacillus cereus, Bacillus licheniformis, Aspergillus niger and Aspergillus oryzae, the inoculation amount of each bacteria is 0.2% of the organic raw material, and the combined enzyme agent is 8000U / g protease , a mixture of 1000U / g cellulase, 5000U / g dextranase, and 5000U / g pectinase, the organic raw material is soybean meal, peanut meal, rapeseed meal, straw in a weight ratio of 2:1:2:3 Mixed mixture.

[0044] The above fermented composition is used for composting, and its preparation method is as follows: first mix the combined enzyme agent, microbial mixed bacterial agent, water and salt according to the required ratio to form a degrad...

Embodiment 2

[0046] The difference with embodiment 1 is:

[0047] The raw material composition and weight ratio of the fermentation composition are: microbial mixed bacterial agent 1.5, combined enzyme agent 0.5, organic raw material 100, water 10, and the inoculum amount of each bacterial strain in the described microbial mixed bacterial agent is 1.5% of the organic raw material. 0.3%, the combined enzyme agent is a mixture of 5000U / g protease, 1000U / g cellulase, 7000U / g dextranase, and 3000U / g pectinase, and the organic raw materials are soybean meal, peanut meal, straw press The mixture is mixed in a weight ratio of 1:1:2.

[0048] In the preparation method, the temperature of aerobic fermentation is kept at 30-40° C., and the aerobic fermentation time is 10 days.

Abstract

The invention discloses a microorganism fermenting composition. The microorganism fermenting composition is prepared from the following raw materials in parts by weight: 1 to 1.5 parts of microorganism mixed inoculant, 0.5 to 1 part of combined enzyme, 100 parts of organic raw materials and 10 to 20 parts of water. The microorganism fermenting composition is prepared by performing aerobic fermentationon on the raw materials at a temperature of 25 to 50 DEG C, wherein the microorganism mixed inoculant are prepared from bacillus subtilis, bacillus megaterium, bacillus cereus, bacillus licheniformis, aspergillus and aspergillus oryzae; the combined enzyme is a mixture of protease, cellulase, glucanase and pectinase; the organic raw materialsare selected from at least two of soybean meal, peanut meal, vegetable meal and straw. By adopting the microorganism fermenting composition, composting and fertilizing can be realized simultaneously, the fermenting period is short, and the production of odor is prevented.

Description

technical field [0001] The invention belongs to the field of agricultural organic waste treatment, and in particular relates to a microbial fermentation composition which can be used for both composting and feed making and a preparation method thereof. Background technique [0002] Agricultural organic waste is a general term for organic substances discarded by humans in the process of organizing agricultural production. Agricultural organic waste mainly includes plant waste and domestic waste. It is a huge quantity and widely distributed, causing serious pollution hazards, but at the same time it has the characteristics of resource utilization and is a valuable biomass resource. [0003] There are many ways to use agricultural organic waste as a resource, including fertilizer, feed, energy, matrix, and industrial raw materials. Fertilization is the compounding of microorganisms with specific functions and agricultural organic waste, and after harmless treatment, a fertiliz...
