When planting peach trees, you can refer to the following fertilization methods:
1. Pre-bud fertilizer. Generally applied 15 days before the Beginning of Spring, this can both make up for insufficient or missed fertilization after fruiting and promptly replenish nutrient deficiencies in the peach tree. Generally, apply 0.5 kg of urea, 0.3 kg of potassium chloride, and 0.2 kg of superphosphate per peach tree, which can be mixed with decomposed human manure and urine and applied as a root-zone topdressing.
2. Pre-flowering fertilizer. Apply 15 to 20 days before flowering, mainly nitrogen fertilizer, with 0.5 to 1 kg of urea and 0.25 kg of boron fertilizer per tree. Be sure to mix it with farmyard manure.
3. Pit-hardening fertilizer. When the pit hardens, the nutrient demand increases, so fertilizer should be supplemented promptly, mainly with full potassium fertilizer, supplemented by nitrogen and phosphorus fertilizer, and applied in combination with farmyard manure. Generally, apply 0.3 to 0.5 kg of potassium chloride per peach tree.
4. Fruit-harvest fertilizer. From 1.5 to 20 days before harvest, the fruit expands more rapidly, and applying potassium fertilizer can effectively increase the yield and quality of peaches. After harvest, mainly apply nitrogen and phosphorus fertilizer; for every 50 kg of fruit, apply about 1.5 to 2 kg of urea and 1 to 1.5 kg of superphosphate to promote strong root development and enhance overwintering ability.
5. Foliar fertilizer. Foliar fertilizer can be applied to peach trees from after leaf expansion until within 20 days before leaf fall, and can also be applied together with disease and pest control. Boron, zinc, manganese, and potassium fertilizers are preferable. Spray on sunny days. Fertilizer types include 0.1% to 0.25% boric acid, 0.1% zinc sulfate, 0.25% to 0.3% manganese chloride, 0.3% to 0.5% potassium dihydrogen sulfate, and 0.2% to 1% ferrous sulfate; on barren land, the amount can be appropriately increased.
In addition, choose excellent peach varieties with large fruit and sweet flavor. Do not plant crops under peach trees, and do not leave weeds; when pruning, balance density reasonably to ensure sufficient sunlight, and pruning should continue throughout the entire growing period.
