Embodiment 1

[0023] Choose 8 broiler chicken farms, add the additives described in 1‰ in the litter, and the thickness of the litter is 30-40cm. The litter is piled up. After 3 days, the temperature rises to about 75°C. After 3 days, the temperature begins to drop. When it drops to When the temperature is around 26°C, spread out the litter and serve chickens.

[0024] After the last batch of broilers are released, the litter is piled up again. After 3 days, the temperature rises to about 75°C, and after maintaining for 3 days, the temperature begins to drop. When the temperature drops to about 26°C, spread the litter, and the chickens can be loaded, and the thickness of the litter can be observed. It directly reflects the degradation degree of chicken manure. as follows figure 1 shown.

[0025] Depend on figure 1 It can be seen that during the 496 days of using the additive process, the chicken manure on the breeding site did not increase in any way, and was completely degraded on site....

Embodiment 2

[0027] Take about 6 tons of meat duck feces, add 1‰ of the additives according to the volume of the feces, pile up more than 70cm, and after 6 days, the temperature will rise to about 75°C, keep it for 7 days, and stir once; after 6 days, the temperature will rise to about 75°C, and keep it for 7 days , stir once. In such a cycle, the amount of feces will become less and less until the remaining amount does not exceed 100 kg, and it will be buried deeply.

[0028] Depend on figure 2 It can be seen that after 5 cycles of using the additive process, 6 tons of meat duck manure was degraded to less than 100 kg.

Abstract

The invention provides a compound microorganism additive and application thereof to degradation of poultry excrement. The compound microorganism additive comprises the following components: denitrifying bacteria with content being no less than 5*10<6>/g; white aspergillus with content being no less than 8*10<10>/g; and bacillus subtilis with content being no less than 4*10<6>/g. The additive provided by the invention uses the denitrifying bacteria and the white aspergillus as main components and can convert proteins in the poultry excrement into nitrogen which is discharged; at the same time, a carbon source in the poultry excrement can be converted into energy which is released, so as to achieve the goal of degrading the poultry excrement; and since design strains in the formula are nontoxic and do not influence the growth of poultry, the compound microorganism additive can be used on breeding sites. Compared with similar additives, the compound microorganism additive has the advantages of high safety, high efficiency, good specificity, less dosage and the like; and when the additive is used on the breeding sites for degrading the poultry excrement, the goal of zero excrement discharge on the poultry breeding sites can be achieved.

Description

technical field [0001] The invention belongs to the technical field of breeding, relates to management on the breeding site, in particular to a compound microbial additive and its application in degrading poultry manure. Background technique [0002] The digestive tract of poultry is short, and most of the nutrients are excreted from the body, causing secondary pollution to the environment; fresh poultry manure accumulates on the breeding site, leading to the spread of pathogenic bacteria. With the improvement of national laws and regulations, the treatment of manure at the breeding site is becoming more and more important. [0003] In poultry manure, the protein content is high, which is the main source of ammonia and hydrogen sulfide in the breeding site; the fiber in the manure is the main part of the structure, accounting for more than 80% of the volume of the dried manure; in addition, the pathogenic bacteria in the manure are important source of pollution.
