Problems solved by technology

At present, compared with natural composting, most of the existing composting fermentation agents can shorten the composting start-up fermentation time, but the high temperature period is too short, the composting cycle is still long

Abstract

The invention discloses a method for stimulating rapid decomposition of organic waste and a special stimulating preparation thereof. The organic waste compost stimulating preparation comprises an independently packaged liquid component A and an independently packaged solid component B; the independently packaged liquid component A is a mixed fermentation bacterial liquid of bacillus subtilis and trichoderma harzianum; the independently packaged solid component B is prepared from the following components in parts by weight: 300 to 600 parts of a phosphate solubilizing bacterium agent, 200 to 600 parts of biochemical fulvic acid raw powder, 300 to 600 parts of charcoal, 0.005 to 0.015 part of a gibberellic acid solid preparation and 0.00001 to 0.01 part of auxin. The mass ratio of the independently packaged liquid component A to the independently packaged solid component B is 1: (1.5-4). The organic waste compost stimulating preparation can quickly increase the compost temperature, prolong the high-temperature period, accelerate the increase of the number of microorganisms in the compost body, promote compost decomposition and shorten the fermentation period.

Description

technical field [0001] The invention belongs to the technical field of resource utilization of organic waste, and in particular relates to a method for stimulating rapid decomposition of organic waste and a special stimulating preparation thereof. Background technique [0002] Fertilization is one of the important ways to recycle organic waste. It takes 15-20 days to fertilize most organic wastes in China to reach the harmless standard, while it usually takes 45-60 days to ferment high-quality organic fertilizers. The long cycle is The main bottleneck of composting technology. The research found that adding caramel, polyethylene glycol, medical stone, waste lime, and traditional Chinese medicine residue can significantly shorten the fermentation cycle. In comparison, the inoculation of microbial decomposing bacteria agent is an effective and economical method. [0003] The key to shortening the composting cycle and achieving a good composting effect in the fertilizer treat...
