How can we use pig manure to ferment organic fertilizer?
The production of organic fertilizer can make a large number of microorganisms in the soil multiply. There are various enzymes secreted by animal digestive tract and produced by microorganisms in the organic fertilizer of pig manure. These substances can improve the enzyme activity of the soil when applied to the soil.
How can we use pig manure to ferment organic fertilizer?
1. Early stage fermentation: organic manure production is necessary to build a 3 m wide × 50 m long fermentation tank (which can ferment more than 200 tons of raw materials), or one machine with multiple tanks, and then pile the raw materials (feces, biogas residue, straw) in the fermentation tank, mix 1 kg of decomposing agent with 20 kg of water in the raw material pile, 1 kg of decomposing agent can ferment 1 t of raw materials, mix them according to the comparison of raw materials, the temperature is about 0 ℃, the fermentation cycle is 7-10 days, and toss once every 2 days, It can be completely decomposed.
2. After fermentation, the raw materials of organic fertilizer are crushed by a semi wet material crusher, screened by a roller screening fertilizer production machine, and the coarse materials are screened out for further fermentation. The fine materials are granulated. The appearance of the particles is more beautiful and the granulation rate is higher.
3. After fermentation, the materials (moisture content is 35%) are mixed by blender, and then dried by organic fertilizer granulator, then dried by organic fertilizer dryer, cooled by cooler, screened by roller screening machine, unqualified products are returned to fertilizer production line, qualified products can be coated with calcium, magnesium, sulfur and other trace elements by coating machine, powder flapping machine, and can be produced by bin through packaging machine Products.
