The row spacing of ginkgo trees is 2-3× 4m. Cylindrical or sparsely layered trunk. The height of grafted seedlings is 80 cm. After cylindrical growth, choose a strong branch as the extension branch of the middle trunk, the second bud branch is cored or thinned, and the other branches are not cut, and slowly released. In the second year, the extension branches of the middle trunk were also cut by 80 cm to promote branching and control competitive branches, while other branches were not cut and released slowly to form fruiting branches. In the third year, the middle trunk extension branch is still cut 80 cm, and the lower biennial branch is slowly read. At this point, the cylinder has been formed, so that the height of the tree is 3 meters and the branches are 2.5 meters. Retract and prune the long branches beyond the range of branch spreading. As a result, the branches with a thickness of more than 3 cm will be retracted and updated in time, maintaining the cylindrical tree structure, ensuring the reasonable group structure and sufficient illumination in the whole garden, which is conducive to high and stable yield.

Ginkgo tree has strong dryness, cylindrical shaping conforms to nature, forming quickly and bearing early fruit. The pruning technology of apple trees can be used for reference for thinning and pruning.
