(1) Select a small crown. In the past, the big crown (thinning, crossing and drying) was rare in production, and it was replaced by the middle crown (thinning small crown, improved spindle, free spindle, etc.). ) and small crown (slender spindle, trunk, etc. ).

(2) Pay attention to canopy illumination and remove excessive branches. Now it has turned to the stage of "quality" benefit, and it needs good ventilation and light transmission conditions to produce high-quality fruits. The past close planting system has not adapted to the current market situation. Therefore, crown control and shaping has become a pruning task for many years to come, changing dense planting crown into light-sparse crown, changing high-yield crown into medium-high-yield crown and changing high crown into short crown.

(3) Pay attention to pruning in four seasons, especially in summer. On the basis of pruning in winter, we should pull branches and carve branches in spring, girdle, girdle and twist cores in summer, and pull branches and thin branches in autumn, so as to minimize the pruning amount of trees, change waste branches into branches, change long branches into short branches and change leaf buds into flower buds, and promote the transformation of trees to early fruiting, high yield and high quality.

(4) Pruning technology is changing from focusing on short cutting to "the strong will pull, the weak will shrink, the dense will be sparse, and the cutting will be less", from complexity to simplification, and the tree structure is changing from multi-backbone branches to less backbone branches, and from multi-level to less-level. The technique of balancing tree potential and branch potential commonly used in pruning is used less and less, and more is to shrink branches. This makes the pruning technology clear at a glance, easy to understand and learn, and easy to popularize and popularize.

(5) From simple manual pruning to the combination of manual, mechanical and chemical regulation.
