Sheep dung can be used as fertilizer for crops and flowers. However, sheep dung can only be applied to farmland after it is fermented to obtain sheep dung organic fertilizer. Because sheep dung contains coliform, nematode and other bacteria and pests that are directly applied to farmland, which will lead to the spread of diseases and pests, crop disease, and also cause the phenomenon of burning roots and seedlings. Therefore, sheep dung needs to be fermented to be safer.
The fermentation process of sheep manure organic fertilizer: first, dry the cow manure to control its moisture content below 85%, and then add straw powder, the proportion of which is 7:3, so that the carbon ratio of raw material (cow manure) and auxiliary material (straw powder) is controlled at 23~28, and the water content is controlled at 52%~68%. Finally, add organic fertilizer fermentation and ripening agent.
After the raw materials, auxiliary materials and bacterial agents are mixed and stirred, they can be piled up for fermentation. The requirements for piling up are to pile the mixture on the fermentation ground into trapezoidal stacks with a width of 1.8 meters to 3 meters at the bottom, a width of 0.8 meters to 1 meters at the top, and a height of 1 meters to 1.5 meters. The spacing between the stacks is 0.5 meters. After stacking, the temperature will rise to more than 60 ℃ within 24~48 hours, and the stacking will start after maintaining the temperature for 48 hours. You can also build a fermentation tank 50 meters long and 4 meters wide, and build multiple tanks. The mixture shall be stacked and laid flat in the fermentation tank, and then the organic fertilizer equipment fermentation tipper shall be used for tipping, and the tipping depth can reach 0.7m-1m. Mechanically turn the pile evenly and thoroughly, and turn the low-layer special materials into the middle and upper part of the pile to fully decompose. After the first overturning, it will be overturned every day.
Sheep manure organic fertilizer is applied to farmland, which is rich in organic matter. This kind of biological fertilizer is needed for planting greenhouse vegetable crops. It not only has the advantages of good fertilizer efficiency, safe and convenient use, but also has the advantages of disease resistance, growth promotion, fertility and other advantages.
