Embodiment 1

[0032] A method for harmlessly producing organic fertilizer from livestock and poultry manure, comprising the following steps:

[0033] Step 1. Evenly sprinkle the fermented microbial strains on the fresh pig manure in the cesspool of the pig farm with a water content greater than 70%, without stirring; wherein, during the sprinkling process, control the mass ratio of the fresh livestock and poultry manure and the fermented microbial strains The ratio is 1000:1, and the frequency of sprinkling is once every 2 days.

[0034] Step 2. The first day of fermenting microbial strains is recorded as the first day. After 1 to 2 days of fermentation, use a dry-wet separator to dehydrate and adjust the water content of livestock and poultry manure to 50% to 60%, and complete the pretreatment. Obtain pretreated pig manure.

[0035] Step 3: Transport the pretreated pig manure obtained in step 2 to a fermentation tank, and add 20% of the pretreated pig manure as an auxiliary material to ad...

Embodiment 2

[0038] A method for harmlessly producing organic fertilizer from livestock and poultry manure, comprising the following steps:

[0039] Step 1. Evenly sprinkle the fermented microbial strains on the fresh cow manure in the cesspool of the cattle farm with a water content of 50% to 70%, without stirring; wherein, during the sprinkling process, control the fresh livestock and poultry manure and the fermented microbial strains The mass ratio is 1000:2, and the frequency of sprinkling is once every 3 to 4 days.

[0040] Step 2. The first day is recorded as the first day when the microbial strains are sprinkled for the first time. After 3 to 4 days of fermentation, the water content of livestock and poultry manure is adjusted to 50% by adding auxiliary materials, and the pretreatment is completed to obtain the pretreated cow dung.

[0041] Step 3, transporting the pretreated cow manure obtained in step 2 to the fermentation tank, and adding 10% of the pretreated pig manure as an a...

Embodiment 3

[0044] The test of the organic fertilizer produced in Embodiment 1 using cabbage and cauliflower in Ducheng Town, Huangzhou District, Huanggang City

[0045] Test conditions:

[0046] Test crops: head cabbage, cauliflower.

[0047] Organic fertilizer for testing: the organic fertilizer produced in Example 1. Specification 40kg / bag, content of organic matter ≥ 57%,

[0048] NPK≥5.6%, moisture 22%.

[0049] Test treatment plan:

[0050] ① Control (apply 30kg of compound fertilizer per mu, 15kg for bottom application and topdressing).

[0051] ② Control + base application of organic fertilizer 50kg / mu;

[0052] ③ Control + base application of organic fertilizer 100kg / mu.

[0053] Experimental results: the average yield of cabbage and cauliflower plots was analyzed by variance, and the difference between treatments was extremely significant. The yield of cabbage with 50kg of organic fertilizer increased by 114kg / mu, 3.4% compared with the control; the yield of cabbage with 100...

Abstract

The invention provides a method for producing an organic fertilizer from livestock manure in a harmless manner. The method comprises the processes of pretreatment and fermentation, wherein the pretreatment process comprises the following steps: firstly, spreading fermentative strains on fresh livestock manure, and controlling the mass ratio of the fresh livestock manure to fermentative strains to be 1000: (1-3) once every 2-6 days; secondly, fermenting for 1-7 days and adjusting the water content to complete the pretreatment process. The technical problems of the technology for producing organic fertilizer from fresh livestock mature in the prior art that the fermentation time is long, the plant is odorous and the environmental pollution is easily caused are solved. According to the method for producing organic fertilizer from livestock manure in a harmless manner, fresh livestock mature is directly subjected to fermentation pretreatment in advance to be partially fermented, so that odor produced by mature and environmental pollution can be greatly reduced; the scattered fermentative microbial strains do not need to be stirred; after pretreatment, secondary fermentation is carried out on the strains, therefore, the fermentation speed is improved, and the time cost is reduced; the addition times and the dosage of the stains can be reduced by more than half, and the cost is reduced; after the organic fertilizer is applied to crops, an obvious yield-increasing effect is achieved.

Description

technical field [0001] The invention relates to the technical field of organic fertilizers, in particular to a method for harmlessly producing organic fertilizers from livestock and poultry manure and the organic fertilizers. Background technique [0002] In the traditional harmless treatment of livestock and poultry manure and the production of organic fertilizers, fresh manure is first loaded and transported to the production factory. In the fermentation tank of the factory, each batch of manure must be mixed with auxiliary materials, added bacteria, fermented, and turned over. Stacking, decomposing and other methods. This method has six major defects: one is that the fresh feces just discharged have a high water content, which is extremely inconvenient for loading, transportation, and unloading; Loading, transportation, and unloading are laborious and mechanically troublesome, and the expenses are high; the fourth is to simply separate dry and wet, and each batch of fece...
