The total fertilization period of peanuts was 250-300 kg of organic fertilizer, 8-11 kg of nitrogen fertilizer, 416 kg of phosphate fertilizer, and 7.8 kg of potash fertilizer. Organic fertilizer is used as base fertilizer, and nitrogen and potassium fertilizer are applied to base fertilizer and top dressing twice. Basal fertilizer: 250,300 kilograms of organic manure in Mushi, 9-8 kilograms of ammonium urea, 6.8 kilograms of ammonium phosphate, 6.7 kilograms of potassium chloride, 1.25 kilograms of zinc sulfate per acre in a zinc-deficient soil, and deficient in boron. Per acre can be applied at the end of borax 0.25? 0.5 kg, molybdenum fertilizer can be 0.2? 0.35% ammonium molybdate aqueous solution soaking. Acidic soil can apply 25 to 50 kilograms of lime per acre, and 5 to 7.5 kilograms of gypsum powder per acre of alkaline soil. Dressing fertilizer: If the basal fertilizer is insufficient, the seedling period may be suitable for top dressing. Flowering period to drum grain period should be based on the growing trend of dressing, generally topdressing 8-11 kg of urea, potassium chloride 7-8 kg. After the top dressing, peanuts can be sprayed with a 2% to 3% solution of calcium superphosphate 2-3 times after 7 days and 10 to 10 days. If the growth is weak, 100 to 200 grams of urea can be added. With spraying. Zinc deficiency, boron deficient soil, in the case of basal zinc and boron without applying, can spray 0.1% ~ 0.2% zinc sulfate or borax aqueous solution in the seedling stage to initial flowering period, continuous spraying 2-3 times.
