(1) Pruning period. Jujube pruning is generally divided into winter pruning and summer pruning. Winter pruning can generally be carried out after defoliation and before the next year's sap flow. However, due to the long dormancy time and poor healing ability of jujube trees, pruning in winter should not be carried out too early, and February-March is generally suitable. Summer pruning was carried out from late May to early June, when the growth of jujube head began to slow down.

(2) pruning method. The common pruning methods of jujube trees are thinning, retracting, cutting short, coring and carving.
