Three methods for quick-impact compound soil
The earth-based compound fertilizer is rich in nitrogen, phosphorus and potassium, which not only has significant fertilizer effect, but also has no pollution and residue, and can effectively improve the soil-inlaid structure and improve product quality. In the following, the method of composting of several compound fertilizers will be summarized and explored from the actual production and introduced to farmers' friends. Three-element quick-acting compound fertilizer was prepared to take 5.5 kg of caustic soda, 7.5 kg of caustic soda water, 1.6 kg of bovine bone powder and beef bone water, 3.6 kg of old nitrate water, 55 kg of nitrate-cooled water and 24 kg of smoked soil. First pour caustic water into a large iron pan, then pour boiled bone water and old salt water, heat the wok, boil the bovine bone powder, cold salt, and caustic soda into the pan. When the cooked product is in a sticky porridge, it is re-entered into the fumigated soil, and it is continuously and uniformly stirred in the pan. When the mixture in the pan is pulverized into a powder, the pan can be cleaned until it is naturally cooled and put into use. The “Summer Hefei†produced according to the above method is rich in N, P, and K, and its fertilizer efficiency is very high. 15 kg of seedlings (50 kg of irrigated or alkali can be used) can receive good results in 5-7 days. It is suitable for crop dressing. . Formulate "5-in-1" quick-release compound fertilizer (1) raw material processing, and convert the plant ash and soft water (river water and pond water) into a pot at a ratio of 1:10 (weight ratio of grass ash and soft water) and filter the impurities to obtain Alkaline water solution; bovine bone powder and soft water are boiled in a ratio of 1:7 (weight ratio of bovine bone powder to soft water) and boiled to remove impurities and obtain the filtrate; the ratio is 1:3 (by weight of salt and water) Prepared as a saline solution; Placing the plaster in a high-temperature calcined stove, remove and break it into a white powder. (2) Manufacturing method. Put 30% alkaline aqueous solution in the pot first, and after boiling, 13% bovine bone water, 25% salt solution, and 2O% gypsum powder are poured into the pot together (while pouring down and stirring), boil About 10-15 minutes later, you can pour the mixed solution boiled in the pot into the pail, and then pour the quick lime with the mixed solution (the quick lime can be piled on the cement floor) until the quick lime is powdery. . (3) Use and effect. According to the above method, 23 kg of “five-in-one†compound fertilizer can be produced for every 50 kg of mixed raw materials, and the contents of nitrogen, iodine, and potassium are respectively 28%, 0.5%, and 30%, which can be used as base fertilizer and top dressing. Preparation of ammonium phosphate quick-release compound fertilizer (1) spare materials. 5 kg of feces, chicken and sheep droppings 10 kg, 5 kg of human urine, superphosphate 3 kg, 0.2% -0.5% sulfuric acid. (2) Production method: Take 5 kg of large feces, and pour it into a large iron pan. Add 0.2% to 0.5% of acid (sulfuric acid, nitric acid, etc.) to make it suitable for soaking and fermentation. About 4 to 5 hours later, 5 kg of human urine, 10 kg of chicken and sheep droppings were thoroughly mixed and poured into a pot, and 3 kg of superphosphate was added to the pot. Then, the iron pan is heated and boiled, and the boiled rice must be stirred in the pan with boiling water until cooked. The phosphorus hinge compound fertilizer produced by the above method is rich in nitrogen and is suitable for crop topdressing. China Agricultural Network Editor
