Weed brewing method uses semi-dry weeds and fine dry soil, human waste mix. When tanning, first spread a layer of 7-10 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 is re-sealed once and then applied for 15 to 20 days. Straw brewing method uses sun-dried straw, wheat straw and other crop stalks with fine dry soil and human and animal dung in a ratio of 6:3:1. The crop straw was drenched with water 1 day before the planting, and it was piled up with fine dry soil and human feces and accumulated about 1.5 meters high and then sealed with pond mud. After 25 to 30 days, turn and seal again, and apply it after 15 to 20 days. Fertilizer brewing method uses chemical fertilizer, fecal urine fertilizer, and fine dry soil in proportion to blending. The specific method is to take 25 kg of calcium phosphate, 25 kg of ammonium sulfate, 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. The piles are compacted and sealed with a plastic film and can be applied for 25 to 30 days. High-temperature tanning method uses pigs, cows, sheep and other livestock manure and turf or fresh weeds in a ratio of 2:1, adds appropriate amount of water and mixes well, then piles them into piles, and seals them with plastic film. After 20 to 25 days, Can be applied. The method of producing urine by manure and urine pooling puts livestock and poultry manure into a closed manure septic tank and directly performs full fermentation, 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. The biogas pooling method uses biogas digesters to ferment high-quality organic manure in high-temperature anaerobic conditions. This method can fully ferment feces and kill more than 95% of bacteria and pests in the feces.
