(1) The pruning of young trees can promote the growth of 2-3 strong branches in the nursery, and can also be reshaped after planting. Plastic surgery will be completed in three years, with minimal pruning. By means of core removal, pulling, bracing and hanging, the sugar orange tree is cultivated into a natural round-headed tree with a stem height of about 30 cm and 3-4 main branches, and each main branch has 2-3 auxiliary main branches, with distinct layers and full crown.
(2) The first fruit tree pruning is combined with shaping, with light pruning as the main method. Cut off the branches of diseases and pests and dead branches, erase the summer shoots, release the autumn shoots, pay attention to cultivating the fruiting mother branches, and keep a proper amount of fruiting branches and vegetative branches every year, which can not only bear fruit, but also continue to expand the crown. With the growth of tree age, the pruning amount will increase step by step. Cut the fruit branches short, and the flowers will fall. For trees that bear fruit for the first time, the top of the crown often draws large and upright branches to compete with each other. Measures should be taken for trees with different growth conditions: thinning strong branches with strong trees and thinning strong branches with straight branches with similar growth conditions to prevent the crown from being strong and weak. The early fruit trees have strong growth potential, easy to produce a large number of summer shoots and serious fruit drop. For trees with strong growth potential, the summer shoots should be erased or removed to ensure fruit and promote production.
(3) Pruning of fruit trees The vegetative growth and reproductive growth of fruit trees tend to be basically balanced, and fruits can be produced inside and outside the crown and up and down. Pruning should update the branches in time, cultivate the fruiting mother branches, keep the proper proportion of vegetative branches and fruiting branches, and prolong the life of high yield as much as possible. Cultivating stout spring shoots and promoting fruiting mother branches are the key to high yield of sugar orange.
(4) Renewal and pruning of aged trees: according to the degree of aging, rotation renewal and pruning, dominant renewal and pruning and main branch renewal and pruning are adopted.
