The principle of jujube pruning must be based on the biological characteristics, natural conditions, cultivation measures and economic requirements of jujube. Specifically, we should not only attach importance to the tree structure, but also be tangible and immortal, without demanding form; Plastic surgery is beneficial to early fruiting and high yield; We should not only pay attention to the firm structure of main branches, but also pay attention to the role of temporary branches in the formation and fruiting; To make all kinds of branches have their growth space, make full use of light energy, so as to be dense but not crowded, not shaded from each other, and ventilated and transparent. In a word, jujube pruning must master the principle of "lengthening the backbone branches, shortening the weak branches, cultivating the strong branches and removing the long branches", keep a proper amount of jujube heads, turn them into fruiting unit branches, and maintain a certain fruiting area to achieve the goal of stable and high yield.
