Aspergillus niger H active decomposition accelerator with bacteriostasis function and preparation method thereof

Abstract

The invention relates to an Aspergillus niger H active decomposition accelerator with a bacteriostasis function and a preparation method thereof. The decomposition accelerator is prepared from autonomously separated, mutagenic Aspergillus niger H strain with multi-zymogram and a high enzyme activity. The Aspergillus niger H strain is preserved at China General Microbiological Culture Collection Center(CGMCC), the address is: NO.1 Yard No.3, West Beichen Road, Chaoyang District, Beijing, China, zip code is: 100101, the accession number is CGMCC No. 7465, and the preservation date is April 12, 2013. The decomposition accelerator not only can decompose organic materials such as straws, livestock and poultry faeces and the like, but also can inhibit soil-borne pathogens. The preparation method for the decomposition accelerator is low in cost and suitable for being popularized by means of a plurality of cheap agricultural-and-sideline products. The Aspergillus niger H active decomposition accelerator with the bacteriostasis function and the preparation method thereof are suitable for middle and small-sized enterprises and peasants to recycle wastes locally, and are safety and non-poisonous, and accord with development demands of ecological agriculture and sustainable agriculture.

Description

technical field [0001] The invention belongs to the application technology of microorganisms in agriculture, and mainly relates to an active decomposing agent with antibacterial function and a preparation method thereof. Background technique [0002] my country can produce more than 500 million tons of crop straw every year, while the production of livestock and poultry manure is as high as 3-4 billion tons. Using straw and livestock and poultry manure to make fertilizer can not only reduce pollution, but also turn waste into treasure. The traditional composting method to process livestock and poultry manure and straw requires a long cycle and requires a large composting space, and the volatilized methane and ammonia gas will cause secondary pollution to the environment; in recent years, the country has vigorously promoted straw decomposing agents to promote direct return of straw to the field . For this reason, various straw decomposing agents have been developed in variou...

Problems solved by technology

[0003] With the rapid development of facility agriculture, continuous cropping and large-scale use of chemical fertilizers and pesticides lead to unbalanced soil nutrients, soil acidification, compaction, and frequent occurrence of soil-borne diseases, which seriously restrict the sustainable development of facility production.
