The first time is mainly fast-acting nitrogen fertilizer, and the second application is NPK compound fertilizer or fruit tree special fertilizer.

(4) foliage: flowering spraying 03% urea, 01% and 0 2% borax, 0.2% ~ 04% phosphoric acid dihydrogen.... Potassium mixture has a good effect on increasing production.

(5) Fertilization method: The vertical roots of cherries are not developed, and the roots are distributed shallowly in the soil, but the horizontal roots are developed.
