Compound bacterium agent for treating green wastes of gardens as well as preparation method and application of compound bacterium agent

Abstract

The invention provides a compound bacterium agent for treating green wastes of gardens as well as a preparation method and application of the compound bacterium agent. The compound bacterium agent isprepared from phanerochaete chrysosporium, trichoderma viride, geotrichum candidum, candida utilis, saccharomyces cerevisiae, bacillus mucilaginosus, bacillus subtilis, lactobacillus plantarum, streptococcus thermophiles and azotobacter chroococcum. When the compound bacterium agent provided by the invention is used for treating the green wastes of the gardens, a carbon-nitrogen ratio and a carbon-phosphorus ratio are adjusted, without the need of adding any auxiliary material; a whole compost fermentation process can be finished through only independently adding the compound bacterium agent,so that the treatment cost of the green wastes of the gardens is effectively saved and a treatment technology is simplified. Microorganisms in the compound bacterium agent can be rapidly and greatly reproduced in a fermentation process, and rapid temperature raising and ageing of compost are promoted; the treatment time of the green wastes of the gardens is shortened and the compound bacterium agent is suitable for treating the green wastes of the gardens in practice.

Description

technical field [0001] The invention relates to the fields of biotechnology and environmental protection, in particular to a composite bacterial agent for treating garden green waste and its preparation method and application. Background technique [0002] Garden green waste can also be called green plant waste, garden organic waste or garden plant waste, which mainly comes from the natural fall of street trees, lawns, parks, etc. Grass, dead branches, fallen leaves, etc. [0003] At present, the most important treatment methods for garden green waste are incineration or landfill, and only a small amount is used to produce organic fertilizers and return to the soil. Landfill and incineration are easy to form secondary pollution and cause waste of limited land resources. Garden green waste is rich in organic matter. Composting and fermenting garden green waste can convert garden waste into bio-organic fertilizer through composting, which has obvious advantages compared with...

AI Technical Summary

Problems solved by technology

However, the composition of garden green waste is complex, and it is quite different from other organic waste such as agricultural waste and animal waste. It contains a large amount of difficult-to-degrade components such as cellulose, lignin and hemicellulose. Takes a long time and doesn't work well

The currently reported garden green waste composting bacteria agents need additional supplementary materials to adjust the C / N ratio, pH, and the need to adjust the aerobic state to promote compost maturity. The treatment process is complicated and the treatment cost is high. Therefore, it is urgent It is necessary to develop a garden green waste treatment bacterial agent that can be used for efficient composting of garden green waste and does not need to add auxiliary materials during the composting process
