How to fertilize peach trees to get high yield?

How can peach trees be fertilized for high yields? Please give guidance on planting peach trees can refer to the following methods for fertilization: 1. Pre-bud fertilizer. Generally, it is applied 15 days before the beginning of spring, which can not only make up for the problem of insufficient or no fertilization after fruit, but also timely supplement the deficiency of nutrients in peach trees. Generally, urea 0.5kg, potassium chloride 0.3kg and calcium superphosphate 0.2kg are applied to each peach tree, which can be mixed with decomposed human excrement as rhizosphere topdressing. 2. Fertilizer before flowering. Apply nitrogen fertilizer 15~20 days before flowering, 0.5~ 1kg urea and 0.25kg boron fertilizer can be applied to each plant, and attention must be paid to mixed application with farm manure. 3. Peach kernel fertilizer. When the peach kernel is formed, the fertilizer required increases, so fertilizer should be supplemented in time, mainly with total potassium fertilizer, supplemented by nitrogen and phosphorus fertilizer, and mixed application of nitrogen, phosphorus and potassium fertilizer combined with farm manure. Generally, potassium chloride is applied to each peach tree 0.3~0.5kg. 4. Fruit picking fertilizer. 1.5~20 days before fruit picking, fruit expansion speed accelerated, potassium fertilizer can effectively improve the yield and quality of peach. After harvest, nitrogen and phosphorus fertilizer were mainly applied, urea 1.5~ 2 kg and calcium superphosphate 1~ 1.5 kg per 50kg fruit to promote root development and enhance overwintering ability. 5. Foliar fertilizer. Foliar fertilizer can be applied to peach trees within 20 days from leaf opening to defoliation, and foliar fertilizer can also be applied in combination with disease prevention and pest control. Boron, zinc, manganese and potassium fertilizers are better. It should be sprayed in sunny days. The fertilizer types are 0.1%~0.25% boric acid, 0.1% zinc sulfate, 0.25%~0.3% manganese chloride, 0.3%~0.5% potassium dihydrogen sulfate, 0.2%~1% ferrous sulfate. The fertilizer can be appropriately increased in barren land. In addition, peach varieties should be selected large, sweet taste of fine varieties. Peaches do not plant crops, do not leave weeds; pruning density reasonable match, ensure sufficient sunlight, pruning process should run through the whole growth period.
