Rapid livestock manure composting method

Abstract

The invention provides a rapid livestock manure composting method. At present, the resource utilization of agricultural wastes such as livestock manure and straw is a difficult problem, straw incineration and disorderly manure discharge cause serious environmental pollution and resource waste, and the utilization rate is only about 20%. The method provided by the invention comprises the followingsteps: taking fresh cow dung as a composting material and crushed corn straw as a conditioning material, and adding white-rot fungi, bacilli, earthworms and biochar to compost for performing auxiliarycomposting, wherein the addition amount of the crushed corn straw is 2% of the quality of the dried cow dung, the length of the corn straw is 2-3cm, and 10 adult earthworms are added to per cubic meter of compost; adding a bacterial agent in the late stage of high temperature, and taking wheat bran as an inoculation matrix, wherein the bacterial agent is prepared from white-rot fungi, bacilli, wheat bran and water in a ratio of 1:1:10:10; and applying 50g of bacterial agent to per kg of compost, wherein the addition amount of the biochar is 5% of the quality of the dried cow dung. The methodprovided by the invention is applied to rapid livestock manure composting.

Description

Technical field: [0001] The invention relates to a method for rapid composting of animal manure. Background technique: [0002] At present, the utilization of agricultural waste resources such as livestock manure and straw is a difficult problem. Straw incineration and disorderly discharge of manure have caused serious environmental pollution and waste of resources, and the utilization rate is only about 20%. Composting is a common method for treating solid manure. This method can effectively improve the utilization rate of agricultural waste organic matter, and the nutrients in the manure after composting are more conducive to the absorption and utilization of plants. However, the current manure of animal husbandry usually contains many harmful substances such as antibiotics and heavy metals, and the use of traditional compost cannot achieve the goal of completely harmless; and the traditional compost takes a long time to decompose and has a low degree of decomposing. At th...

Problems solved by technology

[0003] At present, research on composting mainly focuses on the composting mode, the proportion of composting conditioning materials, and adding bacteria, biochar, earthworms and other substances to compost to maintain nitrogen and promote decay, and remove antibiotics. However, for adding earthworms, microbial agents, There is no report on the comprehensive research of biochar interaction combination on harmless composting of livestock manure, nitrogen retention and promotion of decay
