Compound bacterium agent and method for accelerating fast maturity by inoculating compound bacterium agent to compost

Abstract

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.

Description

technical field [0001] The invention relates to the composting treatment technology of agricultural waste, in particular to a compound bacterial agent and a method for inoculating it in compost to promote rapid decomposition. Background technique [0002] As a large agricultural country, my country has become the country with the largest output of agricultural waste in the world. According to incomplete statistics, the annual production of livestock and poultry manure is about 2.6 billion tons, and crop straw is about 700 million tons, far exceeding industrial and domestic wastewater. total emissions. If these agricultural wastes are not treated scientifically, not only can they not be used as a resource, but on the contrary, these solid wastes contain a large number of pathogenic bacteria, which will cause serious pollution to the environment due to the strong stench produced by the rotting wastes. Composting is the most commonly used effective method for harmless and resou...

Problems solved by technology

And from a large number of reports about compost inoculation at present, it can be seen that most of the microorganisms inoculated belong to mesophilic microbial agents. Microorganisms will die quickly during the high temperature period, so after a short high temperature period, there will be a cooling period, and the composting time is still long, and the composting is not complete, and it is difficult to achieve the expected composting effect
