The “7 advantages†of the starter treatment of chicken manure
The time required for traditional chicken manure fermentation (open air) to reach maturity often takes 1 to 3 months, and the surrounding foul odor is unpleasant. Mosquitoes and flies breed in large numbers, and environmental pollution is very serious. Research at home and abroad shows that the addition of specific microbial flora to chicken manure can effectively promote the degradation of organic matter, accelerate the chicken manure maturity rate, and at the same time help eliminate odoriferous substances and reduce environmental pollution. The main microorganisms that play a key role in the microbial fermentation of chicken manure include bacteria, filamentous fungi, yeast, and actinomycetes, including fibrinolytic bacteria, proteolytic bacteria, yeasts, photosynthetic bacteria, lactic acid bacteria, and deodorizing bacteria. A variety of beneficial microorganisms. Metabolites produced during the growth of these microbes are utilized by each other. In the composting process of chicken manure, the microbial flora is composed of a complex and stable micro-ecology system with excipients and chicken manure, which can quickly ferment chicken manure into fertilizer or feed. The advantages of fecal fermentation in chicken manure fermentation are mainly manifested in the following aspects:
First, start the fermentation quickly. Generally, in the summer, the composting time for composting of chicken manure treated with a microbial starter to achieve an innocuous index is generally about 20 days, and it takes about 60 days for the natural fermentation to reach this target time. Mainly because of the growth and reproduction of microorganisms, the material in the material is fermented and degraded, the time for the compost to reach the high temperature stage is shortened, and the period of high temperature is prolonged. In winter, especially in the north, because the temperature is too low, it is difficult to start the fermentation. Fermentation agent microorganisms can be added to the chicken manure to quickly start chicken manure fermentation.
Second, eliminate pathogenic microorganisms. In the process of microbial manure treatment of chicken manure, the temperature can reach 65 °C ~ 70 °C or even higher, the high temperature not only makes the chicken manure and other materials quickly decomposed, but more importantly it can effectively kill pathogenic microorganisms or viruses among them. The stack temperature of 50°C to 70°C lasts 6 to 7 days for eggs and pathogens. Can achieve a very good lethal effect, such as bird flu virus, 60 °C ~ 70 °C high temperature for a few minutes can cause its death.
Third, remove odors. Adding microbial agents to chicken droppings can effectively remove odorous gases. This is mainly due to the fact that microorganisms can decompose organic substances that do not contain nitrogen and sulfur, such as phenol, carboxylic acid, and formaldehyde, into CO2 and H20; ammonia-containing organic compounds are ammoniated to NH3, and NH3 can be oxidized by nitrifying bacteria to NO2-. Further nitrifying bacteria are oxidized to N03-; sulfur-containing odor substances are decomposed by microorganisms to release H2S, which is oxidized by sulfur-oxidizing bacteria to become sulfuric acid, etc., so that pollutants can be removed.
Fourth, the enzyme activity changes. All biochemical processes in chicken manure accumulation fermentation are carried out with the participation of enzymes. The enzyme activity size reflects the strength of various biochemical processes in organic material composting. Chicken manure composted with microbial inoculants, because the microbial agent contains more microorganisms that produce enzymes such as cellulase, protease, lipase and catalase. Therefore, its various enzyme activities are significantly higher than natural reactors.
Fifth, increase fertilizer efficiency. Microorganisms can decompose the more easily decomposed substances such as starch, lipid compounds, hemicellulose and protein in chicken manure, as well as part of cellulose and a small amount of lignin, some of which are converted into water-soluble carbon and nitrogen compounds, and they are initially used by microorganisms. Some of the carbon and nitrogen sources are gradually decomposed and released as the microorganisms die. Therefore, the water-soluble carbon and nitrogen content in the feces can be increased. Compared with the natural fermentation of chicken manure, various enzymes produced by microbial agents can catalyze the rapid conversion of organic matter into humic state, and the inoculation of microbial compost can produce more humic carbon and nitrogen at the same time. On the other hand, microbial agents can produce some acidic substances, reduce the pH of chicken manure, reduce ammonia volatilization during chicken manure fermentation, maintain more nitrogen, increase fertilizer efficiency, and protect the environment.
Sixth, improve the safety of crops. Uric acid and NH4+-N are the substances that mainly affect the normal growth of crops in chicken manure. Microbial microbial agents can promote the conversion of nitrogenous substances in compost to protein nitrogen and NH3+-N, reduce the accumulation of NH4+-N, and can quickly eliminate or reduce the resulting crops. Growth disorders.
Seven, can be made into roughage of other animals. The dry matter in chicken manure accounts for 31% to 33% of the crude protein, of which more than half is non-protein nitrogen such as uric acid, urea, creatine, ammonia, etc., as well as crude fibers and crude fiber contained in chicken manure itself. Therefore, chicken manure is a good feed for livestock, poultry and fish. However, chicken manure contains parasite eggs and some toxic substances and pathogens. It cannot be directly fed with raw chicken manure. Microbial agents must be added to the chicken manure. High-temperature fermentation can become non-toxic and nutritious feed.
