High-temperature cow dung decomposition agent and preparation method thereof

Abstract

The invention discloses a high-temperature cow dung decomposition agent which is prepared from cow dung and a compound microbial agent through fermentation and drying, wherein cow dung particles in the high-temperature cow dung decomposition agent are loaded with compound bacteria of bacillus subtilis, bacillus licheniformis, in-situ composting geobacillus toebii, thermomyces lanuginosus and thermobifida fusca. In addition, the living bacteria count is not lower than 48+ / - 100 millions / g, the high-temperature cow dung decomposition agent is 50-650 [mu]m in average particle size, lower than 15% in moisture content and 6.0-8.0 in pH. The compound microbial agent in the decomposition agent generates plenty of cellulase, hemicellulase and protease, so that cow dung is rapidly decomposed into a simple inorganic nitrogen source and a carbon source, further, plant growth is promoted and soil fertility is improved. Fermentation is carried out under the high temperature environment, so that mesophilic plant pathogen growth is inhibited effectively, and cow dung products fermented through the decomposition agent can be directly used as organic fertilizer to be applied to soil.

Description

technical field [0001] The invention relates to a microbial preparation, in particular to a cow dung high-temperature decomposing agent and a preparation method and application thereof. Background technique [0002] As a large animal husbandry country, China produces a large amount of cow dung every year, but the current treatment of cow dung is mainly to pile up and bury it, which not only occupies land, causes serious pollution to groundwater sources and water systems, but also produces unpleasant smells and is easy to breed mosquitoes Flies are the source of disease. Therefore, the efficient centralized treatment of cow dung is an urgent problem to be solved. Cattle mainly eat silage. After digestion in the rumen, the hemicellulose and cellulose in the silage are degraded to a certain extent, but the cow dung still contains some organic substances such as lignocellulose that are difficult to degrade. These substances can be further transformed and utilized into organic ...
