According to different seasons, the pruning of Ginkgo biloba is generally divided into two types: winter pruning and summer pruning. Winter is the main period of pruning ginkgo biloba, which is of great significance for cultivating high-yield trees and improving secondary yield. It is best to mow in early winter or early spring in winter, not in cold season, otherwise the wound will be difficult to heal and prone to freezing injury and physiological drought. Maintenance and pruning once a year, cut off competitive branches, overgrown branches, dead branches, drooping and aging branches, etc. Make more short branches on the branches and take the top back. The pruning amount in summer is not large, so it can be carried out by combining budding, coring, girdling and girdling. The reproductive male ginkgo is shaped by the central leadership, and the skeleton branches with large opening angles are used as far as possible to make the tree more magnificent. Female plants are shaped by the central leadership or several leaders, but the opening angle of skeleton branches should not be too large to avoid being overwhelmed when they grow up. When selecting a new auxiliary branch every year, cut off the lowest auxiliary branch. At the same time, some appropriate arrangements should be made for different tree types. Thinning and pruning are mainly miscellaneous branches. Generally, short and middle branches are used to change the branching angle, and appropriate bud cutting should be reserved. The grafted ginkgo biloba is shaped into a leaderless dry shape during the plastic pruning process. Mainly to prevent its main branches from extending outwards without restriction, and to avoid increasing the load of each main branch with the growth of trees, resulting in excessive burden on grafting parts. Therefore, the short middle section should be selected, and the cutting buds that can fill the gap in the crown should be selected. When there are too many branches, it should be properly sparse.
