Low-temperature compost inoculant and preparation and application of low-temperature compost inoculant

Abstract

The invention provides a low-temperature compost inoculant which comprises pichia pastoris VT-21 with the cell concentration ranging from 1.0*108 cfu/mL to 5.0*109 cfu/mL, bacillus psychrphilus H H with the cell concentration ranging from 1.0*108 cfu/mL to 5.0*109 cfu/mL, pseudomonas spp. B5-16 with the cell concentration ranging from 5.0*108 cfu/mL to 1.0 *1010 cfu/mL and pseudomonas spp. B6-15 with the cell concentration ranging from 5.0*108 cfu/mL to 1.0 *1010 cfu/mL. According to the low-temperature compost inoculants, through optimum combination of bacteria, culturing and matching according to suitable active units are conducted, the obtained inoculant is large in total variable bacteria number, high in biological activity, good in synergistic effect, capable of enabling organic material compost to rise in temperature quickly in a low-temperature region, and compost products are stable in quality and high in fertilizer efficiency.

Description

technical field [0001] The invention belongs to the field of biochemistry, and in particular relates to a microbial composition, its preparation and application. Background technique [0002] At present, there are mainly nitrogen-fixing bacteria, phosphorus-solubilizing bacteria, potassium-solubilizing bacteria, lignocellulose-decomposing bacteria, and compound microbial bacteria agents at home and abroad. Among them, compound microbial bacterial agents have become an important direction of development at home and abroad in recent years due to their many components, strong adaptability to the environment, and relatively stable effects. Representative products include enzyme bacteria and EM bacteria from Japan, and PSB bacteria from Taiwan. Enzyme bacteria are composed of bacteria, actinomycetes, yeasts, and filamentous bacteria. After application, they can rapidly multiply and spread in the soil. Some microorganisms co-exist with the roots to form mycorrhiza, increase the ab...

Problems solved by technology

In the composting process, temperature is one of the important factors affecting the composting efficiency and the quality of composting products. In low-temperature areas, the ambient temperature is low, and the growth, metabolism and reproduction of high-temperature or medium-temperature microorganisms are limited by low temperature, which makes microorganisms harmful to solid waste in compost materials. Degradation is severely restricted, thereby prolonging the composting cycle, reducing composting efficiency, increasing production costs, and affecting the quality of composting products

[0003] Although some units in our country have successively launched compound microbial preparations with different combinations, the products for composting in low-temperature areas are relatively rare, and in the process of screening and cultivating low-temperature microorganisms, there is a lack of basic theoretical guidance and mature low-temperature bacteria production technology. The complex culture and fermentation process of bacteria and the interaction between various bacteria groups and their mechanism are relatively unfamiliar, resulting in low and unstable product quality, which affects its effect during use
