At present, the price of fertilizers in various parts of the country has increased and the cost of agriculture has increased. Such as self-made fertilizer, can greatly reduce costs. The self-made raw materials for the chemical fertilizers are extensive, the method is simple, economical and practical, and its fertilizer effect is no less than chemical fertilizers. Here are some self-manufacturing methods for high-efficiency indigenous chemical fertilizers: 1. 50 kg of fresh ammonia in soil, 50 g of soybean powder, and 5 kg of cooked gypsum powder. Sealed at 25 degrees Celsius for 3 days. ammonia. 2, 50 kg of soil ammonium sulfate urine, 5 kg of plaster, 25 kg of water, mixing and stirring, closed 10 days after application, fertilizer effect is equivalent to ammonium sulfate. 3, soil fertilizer first smash the superphosphate sifted, and then according to 100 kg of superphosphate on 120-150 kg of human urine after mixing, piled into a cone, with 3 cm thick mud tightly sealed, stacked 7 Days, they can be used, ideal fertilizer effect. Be careful not to stack low to prevent flooding. This kind of soil Compound Fertilizer can be used as base fertilizer, top dressing and seed fertilizer. The base fertilizer can be mixed with manure fertilizer and soil miscellaneous fertilizer; when it is used as a seed fertilizer, it should not be in contact with the seeds to prevent affecting germination. When dressing fertilizer, it can be used as a trench or kansch, and 1 cm away from the root of the crop to prevent burning seedlings. strict. 4, potassium dihydrogen phosphate superphosphate and hot water according to the ratio of 2:5, stir and let stand 48 hours, filter spare; planting ash and hot water according to the ratio of 6:15 stir and let stand for about 10 minutes, after filtration The two filtered solutions are then mixed to prepare a crude solution containing potassium dihydrogen phosphate. The effect is the same as that of potassium dihydrogen phosphate. 5, soil ammonia-nitrogen-phosphorus compound fertilizer with animal bone processing bone powder, is an important delayed fertilizer, generally as the base fertilizer, there are points of bone meal and bone meal. The bone meal is a powder obtained by simply steaming the bone and removing some of the fat. The powder contains 2 to 6% of nitrogen and 15 to 28% of phosphorus pentoxide. It is a high spatula nitrogen-phosphorus compound fertilizer, mature bone meal (also known as defatted bone meal) is the bone after solvent extraction of fat, and then crushed by high-temperature cooking, which contains 1.5 to 5 nitrogen, containing phosphorus pentoxide 16 - 25%, its fertilizer efficiency is also high.
