1, sparsely populated. Sweet cherry is a light tree species. In order to ensure that the entire tree is airy and light-transmitting, some of the overlapping main branches or main branches that are not close to the main trunk that are not covered with space should be removed as soon as possible, and the main branches cannot be filled with space. Stand upright, lateral branches, appropriate short cuts, promote new branches, and form new branches.
2, pull the branches topping. For branches and branches with poor softening effect, the autumn branches are better than spring and summer branches, which can make all the buds develop well and reduce the erect branches. In order to ensure that the branches are substantial, picking up the hearts before and after is conducive to safe wintering.
3, loose soil fertilization. Fertilizer applied fruit tree fertilizer + potassium sulfate and new high fat film. 0.3% potassium dihydrogen phosphate was added for each spraying to protect the late leaves. In late October, the base fertilizer, human excreta + cow dung (or chicken manure) + sand was mixed and piled. After each 50 kilograms, it was applied 1.5 meters away from the trunk. Apply proper amount of water after each fertilization. After fertilizing and watering in the autumn, when the soil is not sticky, the whole garden will be commonly ploughed once to improve the permeability of the soil and be conducive to root growth.
