Description

Technical Field

[0001] The invention relates to the technical field of breeding, and in particular to a method for producing biological organic fertilizer based on livestock and poultry excrement. Background Art

[0002] Livestock and poultry farming is one of the important industries in Qiandongnan Prefecture, Guizhou Province. Large-scale livestock and poultry farming will produce a large amount of livestock and poultry manure. In order to achieve environmentally friendly treatment of these manures, enterprises need to spend a lot of money and manpower costs.

[0003] As we all know, manure is also an important source of fertilizer. However, the traditional practice is to spread manure directly on the fields. This method is not suitable for commercial manure-to-fertilizer technology. The manure of livestock and poultry in breeding enterprises will produce a huge amount of manure in a short period of time. How to achieve deodorization, harmless treatment, and conversion into organic fertilizer in a short period of time is an important research direction. Summary of the invention

[0004] In view of the deficiencies of the above related technologies, the present invention proposes a method for producing biological organic fertilizer based on livestock and poultry manure.

[0005] In order to solve the above technical problems, the embodiment of the present invention provides a method for producing biological organic fertilizer based on livestock and poultry manure, comprising the steps of:

[0006] S1, prepare a fermentation bed, evenly spread the sawn wood surface in the barn, then evenly mix the smoke foam and the microbial agent, and evenly spread them on the sawn wood surface;

[0007] S2, material preparation, weighing and dividing the feces to be processed, weighing and dividing the required auxiliary materials, and weighing and dividing the required decay-promoting agents;

[0008] S3, mixing the feces and the auxiliary material to obtain a fermentation product, and then adding a decay-promoting agent to the fermentation product and stirring the mixture evenly;

[0009] S4, stacking and fermenting the stirred fermented material;

[0010] S5, turning the compost during fermentation and adding microbial agents;

[0011] S6, turn the pile again and air dry.

[0012] Preferably, in step S1, the moisture content of the sawn wood surface is lower than 35%.

[0013] Preferably, in step S1:

[0014] The fermentation bed should be turned over once a month. If the moisture content is high, the turning frequency should be increased according to the actual stock volume.

[0015] The fermentation bed will be replaced after half a year and transported to the organic fertilizer plant.

[0016] Preferably, in step S2:

[0017] The water content of the feces is 70%;

[0018] The water content of the auxiliary material is less than 12%;

[0019] Mix a good amount of the decay-accelerating agent, cornmeal and rice straw bran in a ratio of 1:30 and stir evenly.

[0020] Preferably, in step S3, the feces and the auxiliary material are mixed in a ratio of 3:1, and then the treated decay-promoting agent is added to the fermented product and stirred evenly.

[0021] Preferably, in step S3, the moisture content of the stirred fermented material should be controlled at 50%-60%, so that the material can be formed into a ball when held by hand and can be dispersed when released.

[0022] Preferably, in step S4, the height of the fermentation pile is not less than 1 m, and the width and length are not less than 1.5 m.

[0023] Preferably, in step S4, the fermentation time is 24-36 hours.

[0024] Preferably, in step S5, the compost is turned once every 7 days, and the turning is ensured to be uniform, and the microbial agent is added after the compost is turned 3 times.

[0025] Preferably, the method further comprises step S7: detecting the content of heavy metal elements and the content of elements such as N, P, and K in the fermentation product.

[0026] Compared with the prior art, the present invention can decompose livestock and poultry excrement quickly and efficiently, achieving the purpose of deodorization and harmless treatment within a short viewing angle. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] In this embodiment, in the step S1, the moisture content of the sawn wood surface is lower than 35%.

[0042] Furthermore, in step S1: the fermentation bed should be turned over once a month. If the water content is high, the turning frequency should be increased according to the actual stock. For example, pig manure in pig farms usually has a high water content, so the turning frequency should be increased.

[0043] In this embodiment, the fermentation bed is replaced after half a year, and the replaced fermentation bed is transported to the organic fertilizer plant.

[0044] In this embodiment, in step S2:

[0045] The water content of the feces is 70%;

[0046] The moisture content of the auxiliary material is less than 12%, and the auxiliary material can be mushroom residue, stalks, straw, sawdust, etc.;

[0047] Mix a good amount of the decay-promoting agent with cornmeal and rice straw bran in a ratio of 1:30, stir evenly, and obtain a processed decay-promoting agent.

[0048] In this embodiment, in step S3, the feces and the auxiliary material are mixed in a ratio of 3:1, and then the treated decay-promoting agent is added to the fermented product and stirred evenly.

[0049] In the present embodiment, in step S3, the moisture content of the stirred fermented material should be controlled at 50%-60%, so that the material can be formed into a ball when held by hand and can be dispersed when released.

[0050] Preferably, in step S4, the height of the fermentation pile is not less than 1 m, and the width and length are not less than 1.5 m.

[0051] In this embodiment, in step S4, the fermentation time is 24-36 hours, the fermentation temperature can reach above 50 degrees Celsius, and the highest can reach 70 degrees Celsius. The deodorizing effect can be achieved in about three days.

[0052] In this embodiment, in step S5, the compost is turned once every 7 days, and the turning is ensured to be uniform so that the fermented material can fully receive oxygen and the temperature is uniform. After turning the compost 3 times, the microbial agent is added to continue fermentation.

[0053] In this embodiment, step S7 is also included: detecting the content of heavy metal elements in the fermented product and the content of elements such as N, P, and K. If the test is qualified and meets the pollution-free and national organic fertilizer standards, it will be packaged, and if the test is unqualified, it will be returned to the factory for processing.

[0054] Compared with the prior art, the present invention can decompose livestock and poultry excrement quickly and efficiently, achieving the purpose of deodorization and harmless treatment within a short viewing angle.

[0055] like Figure 2 The figures show the test results of various indicators of the organic fertilizer produced by using cow dung as the main ingredient based on the method of this embodiment.

[0056] like Figure 3 Shown is based on Figure 2The organic fertilizer shown is applied to the organic fertilizer experimental project comparison of Pseudostellaria baicalensis planted in Qiandongnan area of ​​Guizhou Province.
