Based on the application of basal fertilizer and germinating fertilizer in the early stage, the fruit-producing fertilizer was applied in early July, and the phosphorus and potassium fertilizers were the main components. Generally, 0.5 to 1 kg of diammonium phosphate and 0.5 to 1 kg of potassium sulfate were applied to each tree. From August to September, the application of swelled fruit fertilizer, 0.5 to 1 kg of diammonium phosphate and 0.75 to 1 kg of potassium sulfate per plant was preferred. In the early stage, no basal garden fertilizer was applied, and biological bacterial fertilizer could still be applied in this period. While applying the root dressing, the roots are fertilized according to the tree vigor, that is, foliar spray fertilizer, potassium monohydrogen phosphate and other micro-fertilizers can be sprayed, and calcium fertilizer is added at the same time to prevent cracking.
