1. Young tree pruning: Cut off the side branches in time at the young tree stage to ensure that there are two side branches on each branch.

2. Pruning in growth period: Prune dense branches, horizontal branches and pest branches in time during growth period to reduce nutrient consumption.

3. Pruning after flowering: Most of the flowers are backward, so as to cut off the remaining flowers, so as not to affect the results, and apply fertilizer properly during the fruiting period.

4. Pruning after fruit: cut off the unfruitful branches in time and cut off the branches that are too slender from the base.
