1. Picking fruit fertilizer: It is generally applied before budding after defoliation, and can be used in combination with cultivating tillage soil in the winter clear garden. The amount of fertilizer is about 60% of the whole year. Mainly organic fertilizer, with a small amount of inorganic fertilizer. Each can be applied to 100-200 kg of farmyard manure, 15 kg of plant ash, 10-20 kg of human urine, 4 kg of superphosphate and 0.5 kg of urea. Ditch the groove at the outer edge of the canopy, depth 25-40 cm, timely cover after fertilization. 2. Fertilizer before flowering: Generally applied before spring germination, the fertilizing amount accounts for about 20% of the whole year. Nitrogen fertilizer is the main fertilizer. Applying phosphorus and potassium fertilizers, using furrows or acupuncture, deep furrows or hole depths of 15-20 cm. , Nitrogen fertilizer 0.1-1.5 kg, potassium 0.5-1 kg, phosphorus 0.25-0.75 kg. 3. Steady fruit fertilizer: Before and after the summer heat application, the fertilizer amount accounts for about 20% of the whole year, and the available nitrogen fertilizer is used in combination with the phosphorus and potassium fertilizers. The plant applies 0.5-1.5 kg of nitrogen fertilizer, 0.5-1 kg of potassium fertilizer and 0.25-0.75 kg of phosphate fertilizer. 4. Extra-root fertilizer: In the growing season of persimmon trees, spraying spraying with 0.5% urea, 200 times phosphorus fertilizer with potassium dihydrogen or photosynthetic fertilizer, etc., for foliar fertilizer application 3-4 times.
