Embodiment 1

[0031] (1) Weigh 100 parts of liquid culture medium, 10 parts of protective agent and 2 parts of composite bacterial agent, put the protective agent and composite bacterial agent into the liquid medium and mix well to obtain a decomposing agent with degrading cellulose and deodorizing functions.

[0032] (2) Add the decomposing agent to the cow dung, adjust the water content to 60%, stir evenly, and pile it up for composting; the amount of the decomposing agent is 2% of the weight of the cow dung.

[0033] (3) Measure and record the temperature of the pile at ten o'clock in the morning every day. Place one 500mL beaker each containing boric acid and polyvinyl alcohol phosphoric acid on the top of the pile and in front, back, left, and right of the pile, and replace the solution every 24 hours. Use 2% boric acid to absorb ammonia, use polyvinyl ammonium phosphate to absorb hydrogen sulfide, stack for 30 days, and post-ripen for 10-15 days.

[0034] The liquid culture medium sol...

Embodiment 2

[0038] The method is the same as in Example 1, except that in step (1), 80 parts of liquid medium, 15 parts of protective agent and 4 parts of composite bacterial agent are taken.

Embodiment 3

[0040]The method is the same as in Example 1, except that 100 parts of liquid culture medium, 8 parts of protective agent and 3 parts of composite bacterial agent are taken in step (1).

Abstract

The invention relates to the technical field of agricultural compost, and particularly discloses a decomposition agent with functions of degrading cellulose and deodorizing as well as a preparation method and application of the decomposition agent. The decomposition agent comprises 80-100 parts of a liquid culture medium, 5-15 parts of a protective agent and 1-4 parts of a compound bacterium preparation. A solvent of the liquid culture medium is water, and the liquid culture medium comprises 5-9 g / L of glucose, 0.5-0.8 g / L of monopotassium phosphate, 0.3-0.5 g / L of zinc sulfate, 0.6-1.0 g / L of dipotassium phosphate, 0.3-0.5 g / L of sodium chloride, 0.1-0.3 g / L of ammonium chloride, 0.1-0.3 g / L of sodium nitrate, 0.2-0.5 g / L of yeast powder and 5-8 g / L of corn steep liquor. The decomposition agent with the cellulose degradation and deodorization functions has the effect of remarkably increasing the fermentation speed in the high-temperature stage, the degradation efficiency of cellulose, ammonia gas and hydrogen sulfide can be remarkably improved, the composting quality is improved, and the effect is better than that of a commercially available decomposition agent.

Description

technical field [0001] The invention relates to the technical field of agricultural composting, in particular to a decomposing agent with the function of degrading cellulose and deodorizing as well as its preparation method and application. Background technique [0002] The rapid development of the livestock and poultry industry has led to a large amount of livestock and poultry manure produced in my country every year. Unreasonable accumulation of manure will bring negative effects on the health of humans and animals. These organic wastes contain a large amount of medium and micronutrient elements necessary for crop growth. A very good source of organic matter, which helps to increase the sustainable productivity of the soil. High-temperature composting is the most convenient and cost-effective way to recycle these agricultural and animal husbandry wastes. Composting is a humification process in which bacteria and their by-product enzymes mineralize and decompose organic ma...
