After fertilization, the soil is covered and watered.
Plastic trimming. Summer cherry pruning should be carried out immediately after fruit picking. The main technical measures include sparse branching, topping, twisting, pulling branches, etc. The summer pruning weakens the competitive branch forces, adjusts the ventilation and light transmission level in the canopy, increases the amount of branches and nutrient storage, prevents the result from moving outward, and promotes flower bud differentiation. The tree-cut wound is coated with a callus anti-corrosion film to form an anti-corrosion film quickly, which closes the wound and heals quickly. Anti-virus intrusion, spread of anti-corrosion disease, prevention of rainwater pollution, and prevention of cracking of large wounds.
Branching. It is mainly carried out after fruit picking. For some tree trees with poor canopy closure and poor ventilation conditions, the main reason is to remove the dense branches and solve the wind and light conditions in the canopy; for the erect strong branches that seriously affect the wind and light conditions inside the crown To be removed from the base; the backbone branches and perennial branches of the canopy should also be removed from the base.

Control of large cherry pests: red, white spider, peach leaf miner, and red-necked beetle are common pests. The corresponding pesticide should be used in time, and the new high-fat film spray can shield the insects from smell, inhibit the replication of the bacteria, and reduce their resistance. And the amount of medicine used to improve the effect of pesticides
