Abstract

The invention provides an agricultural straw waste aerobic zymophyte combined fungus bag which comprises trichoderma koningii, aspergillus oryzae, bacillus subtilis and streptomyces griseorubens, the ratio of the trichoderma koningii to the aspergillus oryzae to the bacillus subtilis to the streptomyces griseorubens is (4-15): (3-12): (2-8): (5-10) in terms of CFU, and the number of colonies contained in any zymophyte in the combined fungus bag is not lower than 5 * 10 < 9 > CFU / g. By applying the combined fungus bag provided by the invention, the temperature of a straw pile body can be increased, the synthesis and degradation of substances in the pile body can be enhanced, the fermentation time can be effectively shortened, the loss of total nitrogen in the pile body can be reduced, the nutrient level in a decomposed pile material can be increased, and the fertility of straw compost can be maintained.

Description

technical field [0001] The invention belongs to the technical field of agricultural solid waste treatment, and relates to a combined bacterial bag of aerobic fermentation bacteria of agricultural straw waste. Background technique [0002] Crop straw is a by-product of agricultural production and an important biological resource. However, in addition to returning straw directly to the field, using it as fuel, and using it as feed, a large amount of straw is burned or accumulated in the field without any means of disposal, which not only wastes resources, but also pollutes the environment. Composting is an effective way to deal with these wastes, but because straw is mainly composed of lignin, cellulose, hemicellulose, etc., the traditional composting time is long, which is not conducive to the preservation and utilization of nutrients. Therefore, reasonable inoculation of exogenous microorganisms after treatment of straw is beneficial to shorten the fermentation time, reduce...
