2. Nitrogen and phosphorus compound fertilizer. Take 0.5 kg of ammonium bicarbonate and 0.15 kg of potassium chloride. Zinc sulfate 0.025 kg, human excrement 2.5 kg, cow excrement 1 kg (or pig excrement 5 kg), red stone bone powder 20 kg, divided into 5 equal parts, and then spread a layer of red stone bone powder (4 Kg), sprinkle other fertilizers on it, pat it tightly with a wooden board, and then close it with straw or a film cover. After 20-25 days, it will become a nitrogen and phosphorus compound fertilizer.
3. Ammonium phosphate humate. Take 1 kilogram of decomposed biogas residue, add 0.05 kilograms of phosphate rock powder, mix and mix well and pile into a pile, paste a 3-5 cm thick layer of thin mud mixed with cow dung, and then sprinkle with a layer of fine soil, and seal for 40 days It is made into humic acid phosphate fertilizer. Then turn the humic acid phosphate fertilizer into a fine pile, re-pile and paste with thin mud, and then make holes in the pile around the top of the pile, and then pour ammonia water at the ratio of 1 kg of humic acid phosphate fertilizer to 0.05 kg, and use mud The hole is tight. After 8-10 days, it succeeds when there is no smell outside the cave. This compound fertilizer is used as a base fertilizer, and the effect is obvious.
