Sheep manure wrapping technology

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 ...

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 normal life activities of crops, causes crop diseases, and reduces crop yields.

[0003] The patent application number is CN201710468172.5, which discloses a microbial organic fertilizer processing technology. Sheep manure, pig manure, horse manure, bacteria and fungi are evenly mixed, stacked, and fermented in three stages, so that the organic matter is relatively fully transformed However, during the three composting stages, the organic fertilizer is fed with non-sterilized air, and the number of overturning reaches 1-3 times a day, so that a large number of harmful bacteria in the air enter the fermentation stack, which is easy to cause organic waste. Large area pollution of fertilizer
