It can be made according to local raw materials, such as urban domestic waste and various crop straws, leaves and weeds, melon vines, rice straw, loose shells, peanut shells, sawdust, chaff powder, chaff, fruit residue, dry bagasse, edible fungus residue, distillers grains, brewers grains, sugar residue, vinegar residue, starch residue, cassava residue, citric acid residue, soy sauce residue, monosodium glutamate residue, powder residue, tofu residue, medicine residue, oil residue, (Deep-fried round and flat dough-cake) residue, bran bran, cottonseed meal, moldy feed, sludge, sugar refinery and brewery residue, slaughtering waste, hogwash (hogwash), leftovers, human and animal feces and other wastes.

Fermentation fertilizer operation process:

1. The general dosage of bacterial strains is 0.2% -0.5%.    

2. Raw and auxiliary materials and requirements: main materials: fruit dregs, dry bagasse, edible fungus dregs, distillers grains, brewers grains, sugar dregs, vinegar dregs, starch dregs, cassava dregs, citric acid dregs, soy sauce dregs, monosodium glutamate dregs, powder dregs, tofu dregs, medicine dregs, oil dregs, (Deep-fried round and flat dough-cake) dregs, bran, cotton rapeseed dregs, moldy feed, sludge, sugar refinery brewery dregs, slaughtering leftovers, hogwash (swill) water, leftovers, human and animal feces and other bulk materials. Auxiliary materials: various crop straw, leaves and weeds, melon vines, straw, pine shells, peanut shells, sawdust, husk powder, bran, etc. can be dried, crushed, and high carbon.    

3. Raw and auxiliary material ratio: main material: auxiliary material=5:1-3:1.    

4. The moisture content should be controlled at 60-65%, and the material should be held in a ball by hand just enough to release water.    

5. Mix the bacterial strains, main ingredients, and auxiliary materials evenly as required.    

6. At an ambient temperature of 15 ℃ or above, a minimum of 4 cubic meters of material should be stacked at once, forming a pile with a width of 1.5-2 meters, a height of about 0.6 meters, and an unlimited length. Use a stick to open air holes inside the pile.    

7. When the heap temperature rises to 50 ℃, it begins to tip over once a day. If the heap temperature exceeds 65 ℃, it will tip over again. The temperature should be controlled below 70 ℃, as too high a temperature can affect nutrients.    

8. Maturity symbol: The heap temperature has decreased, the material is loose, there is no original odor of the material, there is a slight ammonia smell, and white mycelium is produced inside the heap. 9. Mature raw fertilizer: directly used to produce commercial organic fertilizers, bio organic fertilizers, organic-inorganic compound fertilizers, bio organic-inorganic compound fertilizers, etc.    

Attention: ① The total moisture content of the fermentation mixture should be controlled between 60-65% depending on the ratio of water content. Both too high and too low are not conducive to fermentation, and too little water leads to slow fermentation; Excessive water can lead to poor ventilation, slow temperature rise, and odor generation. Method for determining whether the moisture is appropriate: Hold a handful of material tightly with your hand, and if there is a watermark in the crevice, it will not drip water and will scatter when it falls to the ground. ② If 1 kilogram of urea or 10 kilograms of superphosphate is added per ton for better fermentation effect.
