Problems solved by technology

In the prior art, composting technology is generally used to ferment sheep manure, and the composting temperature can reach above 60°C to inactivate most pathogens and microorganisms, but it is difficult to eliminate pathogens and thermophilic harmful bacteria with spore structure. In addition, the composting process During the process, long-term ventilation and repeated turning are required, which can easily lead to contamination by bacteria. The bacteria, thermophilic pathogens and their metabolites not only inhibit the fermentation of beneficial microorganisms, but also result in incomplete decomposition of sheep manure and incomplete release of nutrients. It also hinders the ...

Embodiment 1

[0025] Step 1: Add corn stalk powder with a water content of ≤20% to fresh sheep manure, and adjust the dry matter content of the mixture to 30-35%;

[0026] Step 2: Grind until the particle size of the mixture is 40 mesh, and mix in 6%wt special additives, and then use 160uW / cm 2 Intensity of ultraviolet radiation for 20 minutes to obtain the fermentation substrate;

[0027] Wherein, the special additive includes the following components in parts by weight:

[0028]

[0029] Step 3: Inoculate bifidobacterium, yeast, propionibacterium, and lactobacillus in the wort medium at a weight ratio of 1:2:1.5:1.9, train them for 10 days at 36°C under nitrogen, and then concentrate Refining to obtain a microbial starter, adding 10%wt microbial starter to the fermentation substrate, stirring at a rate of 90r / min for 30min, compacting, and using a silage wrapper and a polyethylene film to wrap the film tightly, and the packing density is 700kg / m 3 , to obtain a cylindrical ana...

Abstract

The invention discloses a sheep manure wrapping technology. The sheep manure wrapping technology comprise the following steps of step 1, adding auxiliary materials into fresh sheep manure, and adjusting the content of dry mater in the mixture to 30 to 35%; step 2, crushing the mixture, adding 6 to 10wt% of special additive, and radiating for 20 to 30min by ultraviolet ray with intensity of 160 to200muW/cm<2>; step 3, mixing with 10 to 15wt% of microorganism fermenting agent, pressing, and packaging with a film, wherein the pressing density is 799kg/m3>; step 4, fermenting and granulating at the temperature of 30 to 38 DEG C, wherein the special additive comprises the following components in parts by weight: 15 to 23 parts of humic acid, 30 to 40 parts of molasses, 8 to 12 parts of methylfumarate, 10 to 18 parts of calcium peroxide, 0.5 to 2 parts of methoxy-5-nitrophenol sodium salt, and 4 to 11 parts of polyaspartic acid. The sheep manure wrapping technology has the advantages thatthe pollution by impurity bacteria is effectively avoided, the damaged cambia cells of plant are recovered, the conversion rate of sheep manure is improved, and the nutrients are more thoroughly released.

Description

technical field [0001] The invention belongs to the technical field of agricultural organic fertilizer production, and in particular relates to a sheep manure wrapping technology. Background technique [0002] Sheep manure contains 24-27% organic matter, 0.7-0.8% nitrogen (N), 0.45-0.6% phosphorus (P 2 o 5 ), 0.4-0.5% potassium (K 2 O), the fertility is obviously higher than that of other livestock manure, and the manure is finer, so it can be used as a high-quality organic fertilizer. In the prior art, composting technology is generally used to ferment sheep manure, and the composting temperature can reach above 60°C to inactivate most pathogens and microorganisms, but it is difficult to eliminate pathogens and thermophilic harmful bacteria with spore structure. In addition, the composting process During the process, long-term ventilation and repeated turning are required, which can easily lead to contamination by bacteria. The bacteria, thermophilic pathogens and their ...
