Efficient decomposing agent for reutilizing corn stalks

Abstract

The invention discloses an efficient decomposing agent for reutilizing corn stalks. The efficient decomposing agent comprises, by weight, 0.2-0.8 part of plant growth promoting bacteria, 10-18 parts of a sucrose solution, 0.3-0.7 part of white rot fungi, 0.6-1.2 parts of Bacillus subtilis, 0.8-1.5 parts of Thermophilic sporotrichum, 0.3-0.7 part of Bacillus licheniformis, 0.5-1.5 parts of Azotobacter chroococcum, 0.2-0.7 part of cellulolytic enzyme and 0.7-1.5 parts of an Aspergillus niger agent. The decomposing agent and its fermentation technology thereof have the advantages of small nitrogen loss and non-pungent ammonia smell in a fermentation workshop; the pH value after fermentation ends is not more than 8.5; the fermentation temperature of the bottom layer of a compost in the fermentation process is high, and can reach 45 DEG C or above, and the highest temperature of the compost can reach 80 DEG C, so water evaporation is benefited, and the fertilizer drying speed is accelerated; the humus accumulation degree in the fermentation process is high, and the content of humic acid generally exceeds 15%; and an organic fertilizer produced by using the organic material decomposing agent is used in seed germination test, so the germination rate is high, and can reach 95%.

Description

technical field [0001] The invention relates to the related technical field of corn stalk processing and utilization, in particular to a high-efficiency decomposing agent for corn stalk reuse. 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 und...

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.
