Preparation method and application of a compost low-temperature composite fermentation bacterial agent

Abstract

The invention provides a method for preparing a compost low-temperature composite fermentation bacterial agent, comprising steps: S1, taking the number of effective viable bacteria > 1 × 10 8 CFU / mL of Arthrobacter tobacco ZL‑1 bacterial liquid, Brevibacterium cold-tolerant ZL‑2 bacterial liquid, and Helispiribacter hersii ZL‑3 bacterial liquid are mixed in a volume ratio of 1:1:1 to obtain a fermented liquid; S2, step The fermented liquid obtained in S1 is mixed evenly with the corn cob powder according to the mass ratio of 2:1, and dried until the water content is ≤25%, and the compost low-temperature composite fermentation bacterial agent is obtained. The compost low-temperature composite fermentation bacterial agent prepared by the invention can be applied to the composting of fresh feces in autumn and winter, and solves the problem of environmental pollution caused by the difficulty in starting fermentation of the compost in a cold environment and the accumulation of a large amount of feces. In an environment of 5-10°C, the compost with the low-temperature compound fermentation bacteria agent added to the compost body heats up quickly and has a high temperature. It enters a high-temperature period on the 3rd to 4th day and lasts for 8-10 days. The highest temperature is 76.2°C, which has reached the level of composting in my country. harmless standard.

Description

technical field [0001] The technical field of agricultural biology of the present invention, more specifically, relates to a preparation method and application of a compost low-temperature composite fermentation bacterial agent. Background technique [0002] Composting technology is a resource utilization method of livestock and poultry manure with low cost, strong operability and low biological risk. Using this technology, organic matter can be biodegraded under the action of microorganisms, and the high temperature generated by its vigorous activities can kill pathogenic microorganisms and other harmful substances, and finally form a safe and green organic fertilizer. However, composting is easily affected by ambient temperature, especially in Xinjiang and Northeast China. Due to the large temperature difference between day and night and the low temperature for a long time, a large amount of manure cannot be fermented effectively, which brings great challenges to the appli...

Problems solved by technology

However, composting is easily affected by ambient temperature, especially in Xinjiang and Northeast China. Due to the large temperature difference between day and night and the low temperature for a long time, a large amount of manure cannot be fermented effectively, which brings great challenges to the application of composting technology.

[0003] At present, in order to solve the problem of starting and stabilizing the heat preservation of compost in winter, the method of inputting hot steam and hot water, or directly laying heating devices to control and increase the temperature of compost, but these methods are expensive and consume electricity and energy, are not long-term solution
