How is chicken manure fermented?

2, traditional fermentation, then traditional fermentation (open air) often takes 1 ~ 3 months to reach maturity, and the surrounding stench is unpleasant, mosquitoes and flies breed in large numbers, and the environmental pollution is very serious.

The research on rapid fermentation of starter at home and abroad shows that adding specific microbial flora into chicken manure can effectively promote the degradation of organic matter, accelerate the decomposition speed of chicken manure, help eliminate odor substances and reduce environmental pollution.

Bacteria, filamentous fungi, yeasts and actinomycetes are the main microorganisms that play a key role in the microbial inoculum for chicken manure fermentation. , including cellulose decomposing bacteria, protein decomposing bacteria, yeast, photosynthetic bacteria, lactic acid bacteria, deodorizing bacteria and many other beneficial microorganisms.

Metabolites produced during the growth of these bacteria are mutually utilized. In the process of chicken manure compost fermentation, microbial flora and chicken manure form a complex and stable microecosystem, which can quickly ferment chicken manure into fertilizer or feed.

Advantages:

1, enzyme activity changes. All biochemical processes in chicken manure composting are carried out with the participation of enzymes, and the activity of enzymes reflects the intensity of various biochemical processes in organic material composting. Chicken manure compost inoculated with microbial agents contains more microorganisms producing cellulase, protease, lipase and catalase. Therefore, the activities of various enzymes are obviously higher than those of natural compost.

2. Improve fertilizer efficiency. Microorganisms can decompose easily decomposed substances such as starch, lipid compounds, hemicellulose and protein, as well as some cellulose and a small amount of lignin in chicken manure, some of which are converted into water-soluble carbon and nitrogen compounds, while some carbon and nitrogen sources used by microorganisms in the initial stage are gradually decomposed and released with the death of microorganisms.

3. Improve the safety of crops. The main substances that affect the normal growth of crops in chicken manure are uric acid and NH4+-N. Microbial agents can promote the transformation of nitrogen-containing substances in compost to protein nitrogen and NH3+-N, reduce the accumulation of NH4+-N, and quickly eliminate or reduce substances that cause crop growth obstacles.

4. Can it be made into roughage for other animals? . The crude protein in the dry matter of chicken manure accounts for 365,438+0% ~ 33%, of which more than half is non-protein nitrogen such as uric acid, urea, creatine and ammonia, as well as the crude fiber contained in chicken manure itself and a lot of crude fiber in bedding grass. Therefore, chicken manure is a good feed for raising livestock, poultry and fish. However, raw chicken manure contains parasite eggs, some toxic substances and germs, so it cannot be directly fed with raw chicken manure. Chicken manure must be fermented at high temperature by adding microbial agents in order to become non-toxic and nutritious feed.
