Complex microbial agent for fast decaying straws to produce organic fertilizer as well as preparation method and application

Abstract

The invention relates to a complex microbial agent mainly used for fast decaying straws to produce an organic fertilizer as well as a preparation method and the application. The complex microbial agent for fast decaying the straws to produce the organic fertilizer is characterized by being prepared from 15-20% of bacillus subtilis, 16-20% of aspergillus niger, 18-22% of trichoderma reesei, 10-15% of white rot fungi, 10-15% of aspergillus oryzae, 5-7% of alkalophilic bacteria, 5-8% of thermophilic cellulose decomposition bacteria and 5-10% brewer's yeast in percentage by mass, as well as an accelerant accounting for 0.01-0.03% of the total mass of the bacillus subtilis, the aspergillus niger, the trichoderma reesei, the white rot fungi, the aspergillus oryzae, the alkalophilic bacteria, the thermophilic cellulose decomposition bacteria and the brewer's yeast. The complex microbial agent is capable of shorting the straw decaying period; the decayed straw is combined with pig manure to produce the organic fertilizer, and therefore, the straws can be utilized effectively and practically.

Description

technical field [0001] The invention relates to a compound microbial agent mainly used in quick-rot rotting of straw to make organic fertilizer, and its preparation and application. Background technique [0002] Since the reform and opening up, my country's industry has developed rapidly, and traditional agriculture has also made great progress in the process of industrial development. However, there are still considerable problems in the current immature modern agriculture. For example, the use of a large amount of pesticides has caused the deterioration of the ecological environment, and the organic matter of a large number of crops has not been effectively utilized. In recent years, as the air quality problem has become more and more prominent, straw burning, as a major pollution source, has gradually become a hot issue that people pay attention to. my country produces about 1.3 billion tons of various straws (wheat, rice, corn, etc.) every year, of which less than 20% ...

Problems solved by technology

Bacteria that secrete cellulolytic enzymes, hemicellulolytic enzymes, lignin decomposing enzymes and other enzymes have low efficiency under natural conditions, due to the limitations of nutrients, temperature, humidity, pH and other factors

Lignin degradation is the main problem in the utilization of straw materials. There are many degradation methods, including physics, chemistry, and biology. But in general, chemical methods have secondary pollution problems, physical methods have low efficiency, and grinding or The cost of blasting is relatively high, and although the biological method is popular at present, it has not been really applied, mainly due to factors such as long processing period and poor actual effect.
