Prune thinning: 1. Fruit thinning period: it depends on the fruit stability and tree potential of different varieties. For example, varieties with early maturity, small fruit shape and less physiological fruit drop are carried out about 20 days after flowering; If it is a variety with medium maturity, large fruit shape and serious physiological fruit drop, it can be postponed.

2. Fruit thinning standard: The principle is to leave 1 fruit per 16 leaves, and the spacing between each fruit should be about 7 cm. For example, according to the size of the fruit shape, the number of fruits left in each short fruit branch is determined as follows: small fruit type, 2 fruits left in each fruit branch; Medium fruit type, 1 ~ 2 fruits per branch; Large fruit type, each branch 1 fruit.

3. Fruit thinning method: it can be carried out twice. 1 After fruit thinning, after about 20 days, the second fruit thinning will be carried out to determine the amount of fruit left. The specific operations are as follows: (1) First, thinning pests, deformed fruits and small fruits to keep the fruits with the characteristics of this variety and normal development; (2) Keep the young fruit with lateral growth and drooping on the branches. Because the young fruit growing upward is vulnerable to wind damage, mechanical damage, color difference, bagging difficulties and so on. , it is sparse first; (3) Because the young fruit with long longitudinal diameter expands quickly in the future and is easy to grow into fruit, it is best to keep it.
