1. Bud thinning: Prune the branch buds in spring and remove part of the terminal buds.

2. Thinning branches: Thinning branches is a very important method. Removing densely growing branches, cutting off cross branches and overlapping branches can reduce nutrient consumption and increase light transmission.

3. Short cutting: During the dormant period in winter, branches should be cut short.

Key points for pruning and watering cherry trees:

1. Water before flowering. Before germination and flowering, water enough to expand leaves, Water requirements for flowering. Watering this time can lower the ground temperature, extend the flowering period, and sometimes avoid the damage of late frost.

2. Watering during the hard-core stage should be carried out 10--15 days after the flowers fall. At this time, large cherries grow most vigorously and are most sensitive to water supply. Lack of water will cause a large number of yellow fruits with softened cores. Watering will reduce the number of yellow fruits by an average of 38.7% compared with those without watering.

3. Water before harvesting. Watering once 10--15 days before harvesting will have a great impact on the yield and quality of large cherries. This is the period of rapid fruit expansion. If the fruit is short of water and stunted, not only will the yield be low, but the quality will be poor. Watering before harvest increases yield by 20-30% compared with no watering, but watering too late will delay the harvest period.

4. Post-harvest watering, flower bud differentiation is concentrated after the fruit is harvested. In order to restore the tree body and ensure normal flower bud differentiation, top dressing and watering should be carried out. It is better to use less water to wet the soil this time. Afterwards, short-term dry weather is conducive to the formation of flower buds.

5. Seal frozen water. After applying base fertilizer in October, water should be poured immediately to enhance the tree's ability to survive the winter.
