Pruning is one of the important measures for jujube cultivation. Practice has proved that pruning has the following advantages: (1) For young trees, pruning can give full play to the growth advantages of the head extension branches of jujube trees, rapidly expand the crown, form a strong skeleton (including main branches, lateral branches and central branches), and equip with reasonable branches to lay a good foundation for high yield of big trees.

(2) For fruiting trees, pruning can ventilate the tree body, maximize the use of light energy, fully carry out photosynthesis, increase nutrient accumulation, adjust the contradiction between growth and fruiting, and improve the fruit setting rate; By pruning, the bearing base branches are evenly distributed, and the role of stable and high yield of jujube fruit is fully exerted, so as to achieve the goal of high yield.

(3) For the old trees, the old branches are removed by retraction and pruning, and new fruiting branches are added to rejuvenate the old trees and prolong the fruiting period.

(4) By pruning and cutting off branches of diseases and pests, diseases and pests can be reduced.
