Problems solved by technology

In recent years, my country's livestock and poultry waste treatment and resource utilization have achieved some results, but there are still many practical difficulties in fully realizing the energy and fertilizer utilization of livestock and poultry manure
At present, making organic fertilizer from livestock and poultry manure through aerobic fermentation is one of the main ways of resource utilization of livestock and poultry manure, but the composition of livestock and poultry manure is complex, including protein, fat, organic acid, cellulose, semi Composed of cellulose and inorganic salts and other components, currently relying on a single bacterial species or a simple combination of complex bacterial flora is not fully degraded and the speed is slow

Embodiment 1

[0066] Embodiment 1: Degradation effect of single bacterium and compound bacterium to chicken manure

[0067] Weigh a certain amount of chicken manure and place it in a 250ml conical flask, absorb the equal amount of each bacterial solution into the conical flask, and mix evenly, put it in a 55 degree incubator for cultivation, after 15 days, dry the sample and weigh it to Chicken manure without inoculation was used as a control, and the degradation rate of chicken manure was calculated by weight loss method.

[0068] results and analysis

[0069] The effects of different bacterial flora combinations on the degradation of chicken manure were as follows: figure 1 shown. Among all the treatments, the chicken manure degradation rate of the combined bacteria (NJAU-ND8+B5) was the highest at 24.12%, the chicken manure degradation rate of B5 was 17.66%, the chicken manure degradation rate of NJAU-ND8 was 11.77%, and the blank treated chicken manure degradation rate was 17.66%. Th...

Embodiment 2

[0071] Embodiment 2: Degradation effect of single bacterium and complex bacterium to pig manure

[0072] Chicken manure is replaced by pig manure, and all the other operating steps are the same as in Example 1.

[0073] results and analysis

[0074] The effects of different bacterial flora combinations on the degradation of pig manure are as follows: figure 2 shown. Among all the treatments, the combined bacteria (NJAU-ND8+B5) had the highest degradation rate of 22.41%, the degradation efficiency of the single bacteria B5 was 11.37%, the degradation efficiency of the single bacteria NJAU-ND8 was 9.77%, and the degradation rate of the blank treatment was the lowest. was 3.57%. Compared with the blank treatment, the single-bacteria B5 treatment and the single-bacteria NJAU-ND8 treatment, the combined bacteria (NJAU-ND8+B5) had a significant improvement in the degradation effect of pig manure, which increased by 18.84%, 11.05% and 12.64% respectively .

Embodiment 3

[0076] Embodiment 3: Degradation effect of single bacterium and compound bacterium to sheep manure

[0077] Replace the chicken manure with sheep manure, and the rest of the operation steps are the same as in Case 1.

[0078] results and analysis

[0079] The effects of different bacterial flora combinations on the degradation of sheep manure are as follows: image 3 shown. Among all the treatments, the combined bacteria (NJAU-ND8+B5) had the highest degradation rate of 34.12%, the degradation efficiency of the single bacteria B5 was 27.66%, the degradation efficiency of the single bacteria NJAU-ND8 was 21.77%, and the degradation rate of the blank treatment was the lowest. was 7.09%. Compared with the blank treatment, the single-bacteria B5 treatment and the single-bacteria NJAU-ND8 treatment, the combined bacteria (NJAU-ND8+B5) had a significant improvement in the degradation effect of sheep manure, which increased by 27.03%, 6.46% and 12.35% respectively .

Abstract

The invention discloses a high-temperature-resistant livestock and poultry manure degradation complex microbial inoculant and application thereof. The invention aims to further improve the compostingeffect of livestock and poultry breeding manure, the complex microbial inoculant containing Bacillus sp. Bacteria NJAU-ND8 and Bacillus stearothermophilus is developed, and the complex microbial inoculant provides the complex microbial resource and the technical support for the livestock and poultry breeding manure. The application of the complex microbial inoculant is to accelerate degradation oflivestock and poultry breeding excrement. When the complex microbial inoculant is used for degrading the chicken manure, the degradation rate of the chicken manure reaches 24.12% after half a month,and the degradation effect is better than that of single bacteria and blank treatment; after the pig manure is degraded for half a month, the degradation rate of the pig manure reaches 22.41 percent and is better than that of single bacteria and blank treatment; after the sheep manure is degraded for half a month, the degradation rate of the sheep manure reaches 34.12 percent and is better than that of single bacteria and blank treatment.

Description

technical field [0001] The invention relates to the field of agricultural microorganisms, in particular to a high-temperature-resistant compound bacterial agent for degrading livestock and poultry manure and its application. Background technique [0002] At present, the national annual production of livestock and poultry manure is about 3.8 billion tons. Large-scale livestock and poultry manure is a huge organic matter and nutrient resource, but if it is not handled properly, it will have a serious negative impact on the environment and residents' lives. According to the 2010 Bulletin of the First National Survey of Pollution Sources, the chemical oxygen demand discharged by the livestock and poultry farming industry reached 12.6826 million tons, accounting for 96% of the total emissions from agricultural sources; the discharge of total nitrogen and total phosphorus was 1.0248 million tons and 160,400 tons, accounting for 38% and 56% of the total emissions from agricultural...
