Weed production method: Use semi-dry weeds and fine dry soil, human waste mix. When tanning, first spread a layer of 7 to 10 cm thick pond mud or fine soil on the ground, then spread a layer of semi-dry weeds, sprinkling a small amount of human excrement, and then cover 7 to 10 cm thick fine dry Soil, piled up in layers of about 1.5 meters and sealed with pond mud. After 30 to 35 days, it was re-sealed once and then applied after 15 to 20 days. Straw production method: Dry straw, wheat straw and other crop stalks were mixed with fine dry soil and human and animal manure in a ratio of 6:3:1. The crop straws were soaked with water 1 day before the last planting, and they were piled up with fine dry soil and human feces and piled about 1.5 meters high and then sealed with pond mud. After 25 to 30 days, seal once by flipping and apply after 15 to 20 days. Chemical fertilizer production method: Use chemical fertilizer, manure fertilizer, and fine dry soil in proportion to mix. The specific method is to take 25 kg of calcium phosphate, 25 kg of sulfuric acid, 1.25 kg of zinc sulfate, 7.5 kg of potassium chloride, 500 kg of human waste (or 250 kg of pig manure), and 1000 kg of fine dry soil. Piles are compacted and sealed with a plastic film and applied for 25 to 30 days. High temperature product method: With pigs, cows and sheep and other livestock manure and turf or fresh weeds in accordance with the ratio of 2:1, add enough water and mix well after piled into a pile, sealed with a plastic film tamper, after 20 to 25 days can be applied. Septic tank production method: The livestock and poultry manure is put into a closed septic tank directly and fully fermented, which can prevent the ammonia in the open storage and fermentation due to wind and rain from evaporating and the manure cannot be fully fermented.
