Decomposition agent for soybean straw processing

Abstract

The invention discloses a decomposition agent for soybean straw processing. The decomposition agent is prepared from the following raw materials in parts by weight: 0.3-0.7 part of carbonized hair, 0.3-0.8 part of a Bordeaux mixture, 0.8-1.5 parts of thermophilic sporotrichum, 0.5-2 parts of alkyl naphthalene sulfonic acid, 0.3-0.7 part of bacillus licheniformis, 0.3-0.8 part of acid resistant cellulase, 0.8-1.5 parts of acetic acid, 0.5-1.5 parts of azotobacter chroococcum, 0.5-1 part of spore suspension, 0.7-1.5 parts of acrylic emulsion and 0.2-0.7 part of trichosporon mucoides. The decomposition agent and a fermentation process thereof disclosed by the invention have the advantages that the nitrogen loss is less, and ammoniacal odor in the fermentation workshop is not pungent; the pH value does not exceed 8.5 after fermentation completion; the fermentation temperature of a compost bottom layer is high in the fermentation process and can reach 45 DEG C or higher, the highest composttemperature can reach 80 DEG C, evaporation of water is facilitated, and the fertilizer drying speed is increased. The humus accumulation degree in the fermentation process is high; and the organic fertilizer made by utilizing the organic decomposition agent disclosed by the invention has the characteristics of high germination rate and the like.

Description

technical field [0001] The invention relates to the related technical field of soybean straw reuse, in particular to a decomposing agent for soybean straw processing. Background technique [0002] Crop straw is a huge resource with the characteristics of large quantity, variety and wide distribution. According to statistics, the annual output of straw in my country is about 700 million tons, but the utilization efficiency of straw is extremely low, and most of the straw is incinerated and disposed of, causing serious environmental pollution and waste of resources. [0003] At present, straw is mostly used in agriculture by returning it directly to the field. However, due to the slow decomposition rate of straw returning to the field in cold soil and the decrease in soil temperature, which affects the growth of crops, the proportion of straw returning to the field has always been relatively low. Returning straw to the field through composting is undoubtedly the best way to s...

Problems solved by technology

[0005] However, the time required for natural composting is relatively long, and the utilization rate of straw is low. Therefore, it is urgent to develop an efficient microbial compound agent to improve the decomposing speed and decomposing rate of straw.
