Organic material decomposing agent and preparation method thereof

Abstract

The invention provides an organic material decomposing agent and a preparation method thereof. The organic material decomposing agent is mainly prepared by inoculating compound bacterial liquid to a solid culture medium through fermentation, wherein the compound bacterial liquid is prepared from trichoderma harzianum, saccharomyces cerevisiae, lactobacillus plantarum and bacillus subtilis throughmixing after liquid fermentation, and a weight ratio of a trichoderma harzianum liquid fermentation strain to a saccharomyces cerevisiae liquid fermentation strain to a lactobacillus plantarum liquidfermentation strain to a bacillus subtilis liquid fermentation strain is (5 to 15):(15 to 25):(15 to 25):(45 to 60). When the organic material decomposing agent provided by the invention is used for livestock excrement composting, the fermentation temperature can be quickly increased, the highest composting temperature is 75 DEG C, a high-temperature period can last for 10 to 15 days, harmful organisms in livestock excrement can be effectively killed, a large amount of beneficial microorganism and metabolic products which are required by plants can be generated by decomposing organic substances, dewatering and deodorizing can be realized, the composting time can be shortened, and harmless treatment and resource conversion of the livestock excrement can be quickly realized.

Description

technical field [0001] The invention relates to the field of agricultural production, in particular to an organic material decomposing agent and a preparation method thereof. Background technique [0002] my country's current agricultural planting has been using chemical fertilizers for a long time, resulting in a series of planting obstacles such as low soil organic matter content, nutrient imbalance, soil structure damage, compaction, salinization, and the proliferation of diseases and insect pests. And with the abuse of chemical fertilizers and pesticides, pollutants form a vicious circle through the food chain, threatening the safety of human survival. Therefore, my country urgently needs to apply bio-organic fertilizers to improve soil conditions and ensure agricultural planting levels and food safety. [0003] With the rapid development of large-scale and intensive livestock and poultry farming, the production of livestock and poultry manure is also increasing year by...

Problems solved by technology

Currently, less than 30% of the organic wastes in intensive farms are rationally treated, and more than 70% of the wastes are discharged directly into the environment

[0005] The products with the function of decomposing organic matter currently on the market are mainly characterized by decomposing, and the products produced after decomposing materials are not functional; the production process of most products is through compound liquid fermentation of strains, single strain liquid fermentation complex After compounding, it becomes a new product of organic material decomposing agent after simple mixing with the carrier. The production process is complicated, the efficiency is low, the cost is high, the product property is unstable, and the enzyme activity is low.
