Description

A fermentation cylinder for sheep excrement is fermented fast

Technical Field

The utility model belongs to the technical field of sheep excrement fermentation technique and specifically relates to a fermentation cylinder for quick fermentation of sheep excrement.

Background

Sheep is a ruminant, and has little drinking water, so the excrement is dry and fine, the excrement discharge amount is also little, and sheep manure and urine are thermal fertilizers between horse manure and cow manure and urine. The sheep manure contains rich nutrients, not only is easy to decompose available nutrients which can be absorbed and utilized by crops, but also has slow-acting nutrients which are not easy to decompose, and is a good fertilizer combining the fertilizer efficiency and the fertilizer efficiency. The sheep manure contains 24-27% of organic matter, 0.7-0.8% of nitrogen, 0.45-0.6% of phosphorus, 0.3-0.6% of potassium, 5% of organic matter, 1.3-1.4% of nitrogen, very little phosphorus and very rich potassium, and the content of phosphorus is as high as 2.1-2.3%. Therefore, sheep manure is widely used as a waste material.

However, the conventional fermentation of sheep manure is as follows:

the first method comprises the following steps: firstly, uniformly mixing 5-10 times of rice bran (or corn flour, wheat bran, unite bran, straw powder and the like), 0.5 times of brown sugar and a forest culture starter to prepare a strain mixture, and then uniformly mixing the strain mixture with fermentation materials (various animal wastes, crop straws, sludge, organic wastes and the like), stacking and fermenting;

and the second method comprises the following steps: activation before use: fermenting agent, brown sugar and water are mixed according to the proportion of 1: 1: 20, the activation is carried out for about 3 to 8 hours, during which the mixture is preferably stirred sufficiently at regular intervals. Then adding proper water, uniformly sprinkling and mixing. Then the activating solution is evenly mixed with corn flour or bran and the like, and then the mixture is evenly mixed with the materials.

In addition, the above two modes must satisfy the following three conditions:

firstly, moisture adjustment: the water content is controlled to be 50-60%, the material is held by hands to be agglomerated without water drops, and the material is scattered when the hands are loosened.

Secondly, stacking and stacking: the one-time stacking is not less than 3 square, the stacking height is 0.8-1.5 m, when the ambient temperature is below 15 ℃, the covering is covered by a film or a straw curtain, and when the internal temperature is raised to 25 ℃, the covering is uncovered. The stack begins to overturn when the temperature rises to 60 ℃, and needs to overturn for many times every day if the temperature of the stack exceeds 65 ℃. The height is not less than 80cm, and the ambient temperature is preferably above 15 ℃. In winter, the production should be managed to raise the temperature for fermentation.

Third, the mark of maturity: the heap temperature is reduced, the materials are loose, the original odor of the materials is avoided, the materials have slight ammonia odor, and white hypha is generated in the heap.

Although the above methods can achieve sheep manure fermentation, they also have the following problems:

firstly, the stockpile fermentation is in large-area contact with air, the fermentation time is longer, and generally, the fermentation time is 50 days or more;

secondly, the fermentation speed is low, so that the occupied area in the fermentation process is large, and the rapid production is not facilitated;

thirdly, the stacking time is long, the soil needs to be turned over for many times, a large amount of malodorous gas is generated, and secondary air pollution is generated;

therefore, a sheep manure fermentation tank with a simple structure and high fermentation efficiency and a fermentation method thereof are urgently needed.
