2. Vegetative growth period: on the basis of fixed stem and seedlings, the crown is mainly cultivated by shaping, and the main branches and auxiliary branches are continuously cultivated in the first 1 and second years after planting, with lateral branches, so that the tree body is compact and lush. Cultivate shoots 3 ~ 4 times a year, form a crown as soon as possible, and remove buds in time.
3. Growth and fruiting period: continue to cultivate the crown and bear appropriate fruits. Promote new shoots 2 ~ 3 times a year, so that the branches are evenly arranged and a compact crown is formed as soon as possible. The middle and upper parts of plants do not bear fruit or bear little fruit during the day, and pruning is mainly based on bud wiping and shoot control.
4. Full fruiting period: the height of the tree is generally controlled below 250cm, the crown is wide, the periphery is concave and convex, the branches grow healthily, the thickness of the green leaf layer should be above 100cm, and the ventilation is transparent, resulting in a three-dimensional effect. Control the intersection between rows, and the crown coverage rate is 75% ~ 85%. Pruning suitable trees, deleting secrets and keeping sparse, removing the weak and keeping strong; Cut and stay, cut outside and stay inside; Cut down more trees and plant more flowers, and cut down less trees and plant less.
