The high-fertilizer land plots analyzed the absorption of nitrogen, phosphorus, and potassium nutrients and the absorption and utilization of fertilizers according to peanut yields of 500 kilograms per acre. The fertilization ratio was: 14.8 kg of nitrogen per mu, 11 kg of phosphorus, and 16 kg of potassium. It can be used to compose 5,000 kg of high-quality fertilizer, 13 kg of urea or 35 kg of ammonium bicarbonate, 72 kg of superphosphate, 22 kg of potassium sulfate or 18 kg of potassium chloride, or 138 kg of plant ash. The middle fertility plot achieves the goal of 500 kilograms of peanut per acre. The proportion of fertilization is: 27 kilograms of nitrogen per acre, equivalent to 10,000 kilograms of high-quality ring fertilizer, 26 kilograms of urea, or 70 kilograms of ammonium bicarbonate. The amount of other fertilizers is the same. Basal fertilizer is mainly based on organic fertilizers that are decomposed, combined with nitrogen, phosphorus, potassium and other chemical fertilizers. Each acre applies 500-2000 kilograms of quality circle fertilizer, peanut output is 150-200 kilograms; 2500-3000 kilograms of high-quality ring fertilizer is applied per acre, and the production volume is 250-300 kilograms. The poorer the fertility, the more obvious the effect of organic fertilizer, the new whole farmland must apply more organic fertilizer in order to ensure the high yield of the year. Fertilizer top dressing fertilizer: seedlings should be applied before and after the initial flowering, the earlier the better, should be equal to nitrogen, phosphorus and potassium. General use of ammonium sulfate 5-10 kilograms per acre, superphosphate 10-15 kilograms, mixed with 500-1000 kilograms of high-quality ring fertilizer application, or 50-80 kilograms of grass ash, should be mixed with soil or trenching facilities. Flower-needle fertilizer: If the base, Miaofei not enough, it should be based on growing looks, timely application of fertilizer. In addition, according to the characteristics of direct absorption of phosphorus and calcium nutrition in peanuts, young fruit can be topped with 10-20 kilograms of superphosphate and 150-250 kilograms of high-quality ring fertilizer per acre, which can improve phosphorus and calcium nutrition of peanuts. .
