Want to pig manure, chicken manure and other organic waste
into qualified organic fertilizer, aerobic fermentation is an essential link, and want to efficient, fast and good fermentation, not that the fermentation of raw materials to the fermentation tank or a pile of flat ground can be, want to scientific and reasonable aerobic fermentation, then in the fermentation process need to pay attention to the following aspects:
1, To ensure that the fermentation of raw materials can have good ventilation and oxygenation, if the fermentation tank is used for fermentation, then in the tank wall below the reasonable arrangement of vents;
2, Compost height and width to be appropriate, flat compost fermentation, the height of the stack should be between 0.8-1.5 meters, the stack width of 2-3 meters, the use of fermentation tank, the height of the pile should not exceed 1.6 meters, the stack is too small is not conducive to warming, the stack is too high is not conducive to the internal fermentation of raw materials;;
3, Fermentation of raw materials to be fresh enough, if the raw materials before fermentation pile too long, in the fermentation need to add fresh manure for regulation;
4, Open-air compost fermentation in the stack surface should be covered with a cover, to avoid the surface air-dry lumps affect the stack ventilation.
