The invention discloses a compound bacterium agent and a method for accelerating fast maturity by inoculating compound bacterium agent to
compost. The method comprises the steps of: performing enlargement cultivation respectively on high-temperature microbial strains such as
Geobacillus,
Bacillus licheniformis, two
trichoderma,
actinomyces and the like which are screened from the matured
compost, and combining the strains in certain proportion into the compound bacterium agent. The compound bacterium agent is inoculated to the
compost in certain proportion, the compost is moved into a
fermentation tank for aerated aerobic
fermentation, and the compost maturity is completed. Compared with the control compost, the inoculated compost of the scheme of the invention reaches the high temperature period one week earlier than the control compost, and the high temperature period lasts for 14 days so as to be beneficial to the
decomposition and humification of organic matters of the compost; and the inoculated compost is thoroughly decomposed about twenty days later. Through test, most of the
weed seeds, ascarid eggs and colibacillus in the compost are dead, the
humic acid content is 25 g / kg higher than that of the control compost, the humification coefficient is more than 1.9, the decomposed finished product is black brown and odourless, and has excellent stability, harmless and minimized quality, apparently environmental and
economic benefits.
