1. Re-application of fruit-picking fertilizer: before and after the Beginning of Winter to Lesser Snow (November), combined with soil improvement and hole expansion, fruit-picking fertilizer was re-applied to restore tree potential as soon as possible, promote flower bud differentiation and accumulate nutrients for the fruit of the second year. When expanding the hole, each plant applies 15 jin of bio-organic fertilizer, 0.5 jin of phosphate fertilizer and an appropriate amount of nitrogen fertilizer. According to the actual growth of the tree, 0.5% potassium dihydrogen phosphate can be used as external topdressing fertilizer and 0.2% boric acid can be sprayed once to facilitate flower bud differentiation.

After spring shoot germination, 0.5% potassium dihydrogen phosphate and 0.3% urea can be used for extra-root topdressing (spraying) to promote the development of robust branches and flowers. 0.3% urea and 0.5% potassium dihydrogen phosphate can be used for external topdressing in early and middle March, respectively.

3. Stable fruit fertilizer: fertilizer can be applied according to the growth of the tree from April to May. Compound fertilizer is applied to each plant by 1.5 jin. After mid-April, 0.5% potassium dihydrogen phosphate is applied outside the root. After blooming, 0.5% magnesium sulfate and 300ppm anti-falling element are sprayed respectively after flowering.
