Specific method and production process of sheep dung fermentation organic fertilizer
The following is to explain some small details of organic manure fermentation of sheep manure, chicken manure and other livestock manure, using the organic fertilizer production line to produce high-quality fertilizer, to provide strong fertilizer effect for crop production.
1. Temperature control. The best fermentation temperature of animal manure should be 15 ℃ ~ 35 ℃. If it is fermented in winter, indoor or greenhouse is recommended. If it is outdoor, it is recommended to build a temporary fermentation house with plastic film, and the material can be removed after heating.
2. Material mixing. Adding bacteria to dilute according to the proportion, using wheat bran, corn flour, rice bran, etc. without water dilution, feces accounted for the main proportion of fermentation materials.
3. Moisture control. According to the situation after mixing, add water or materials appropriately to control the water content at 40% - 45%. The standard is that there is water between fingers but no dripping.
4.The size of the material pile. The fermentation raw materials are directly piled on the ground, and the fermentation pile should not be too small. A pile with a height of 1.5 meters to 2 meters, a width of 2 meters, and a length of 2 to 4 meters is better for fermentation. The top can be covered with plastic cloth, etc., without sealing, for fermentation. During the fermentation process, the pile should be turned over at an appropriate time, and water should be added or reduced according to the temperature, usually twice. Industrial production of organic fertilizer adopts trough fermentation.
5. Color. When the material is no longer heated, loose and dark brown, the fermentation is completed.
After fermented by bio organic fertilizer and processed by fertilizer granulator, sheep manure has better fertilizer efficiency, safer and more convenient use, and can also improve the utilization rate of chemical fertilizer. Organic fertilizer production line can not only process sheep manure, organic fertilizer, chicken manure, pig manure, cow manure and other livestock manure can be made into organic fertilizer, the fermentation method is basically the same.
Finally, we should remind everyone that no matter what material is used to ferment organic fertilizer, we should grasp the moisture content, otherwise we will fail. High efficiency compound fertilizer can be obtained by deep processing of decomposed organic matter in fertilizer production line.
