Abstract

The invention discloses a compound microbial agent for resourceful treatment of vegetable residues as well as a preparation method and application of the compound microbial agent. The compound microbial agent is prepared from bacillus bh1 bacterial liquid, bacillus bh2 bacterial liquid, bacillus bh3 bacterial liquid, bacillus cereus bacterial liquid and gordonia bacterial liquid, wherein the effective viable bacteria contents of the bacillus bh1 bacterial liquid, the bacillus bh2 bacterial liquid, the bacillus bh3 bacterial liquid and the bacillus cereus bacterial liquid are all greater than or equal to 10<10>CFU / ml; and the effective viable bacteria content of the Gordonia bacteria liquid is greater than or equal to 10<9>CFU / ml. The compound microbial agent provided by the invention can increase the composting speed of straw, and increase the maturation degree and the recycling rate of resources.

Description

technical field [0001] The invention belongs to the technical field of microbial fermentation, and in particular relates to a compound bacterial agent used for recycling vegetable residues and its preparation method and application. Background technique [0002] At present, a large number of vegetable residues are produced every day in vegetable greenhouses, farmers' markets, etc. Greenhouse growers and vendors mostly pile them up in the fields, let them rot, or throw them into trash cans, and finally transport them to garbage dumps for landfill landfill. Improper disposal of vegetable residues has caused serious pollution to the rural and urban environments. Due to the variety, quantity and weight of vegetable residues produced every day, the cost of external transportation and landfill processing is increased. [0003] In fact, vegetable residues contain a certain amount of carbon, nitrogen, phosphorus, potassium, calcium and other elements, and are rich in organic matte...
