Bioanalysis preparation technique of biological organic fertilizer by chicken manure

Abstract

The invention discloses a bioanalysis preparation technique of a biological organic fertilizer by chicken manure. High-efficient and green chicken mature fermenting biological organic fertilizer is developed through a mixed bacteria aerobiotic two-step fermenting technique, wherein an one-step fermenting flora comprises aspergillus, thermophilic sporotrichum, saccharomycetes, bacillus subtilis, thermophilic heterotrophism ammonia oxidizing bacteria; a two-step aerobiotic fermenting flora comprises EM fungicide, azotobacter chroococcum, and bacillus licheniformis. The technique adopts multi-bacterium mixing fermentation; through combination of metabolic capabilities, the complex metabolism which is hard to complete by single culture is completed; through synergic fermentation between microorganisms, the chicken mature is effectively transformed, the hygienic index reaches the national standard, and the product decomposition and growth promoting index are significantly promoted. The fermenting technique is simple and high-efficient, the deodorization and sterilizing effects are good; besides, the production cost is low, and the technique is easy to carry out industrial scale production.

Description

technical field

[0001] The invention relates to a biological process for preparing bio-organic fertilizers using chicken manure, especially a process for preparing bio-organic fertilizers with good growth-promoting and production-increasing effects by using a variety of probiotics to co-ferment chicken manure and straw. engineering field. Background technique

[0002] With the development of modern animal husbandry, the scale and intensification of poultry farms continue to increase, and the feces produced by large poultry farms seriously pollute the environment. The State Environmental Protection Administration’s 2002 survey on the pollution of large-scale livestock and poultry farming shows that the annual livestock and poultry manure volume in China is about 1.9 billion tons, of which COD (chemical oxygen demand) emissions have reached 71.18 million tons, and the livestock and poultry manure output Both COD and COD emissions far exceed the sum of industrial wastewater an...
