Method for increasing grafting survival rate of twigs of jujube trees

The invention relates to the technical field of cultivation of jujube trees and discloses a method for increasing the grafting survival rate of twigs of the jujube trees. According to the method, development branches of the lignified jujube trees are adopted as scions, the scions are grafted onto hard branches after being subjected to wax sealing treatment, and the junctions between stocks and thescions are covered with mud. By means of the provided method, the survival rate is high, the lignification degree is high, the grafting period is prolonged from the late May to the end of July, and the jujube trees can fruit one year earlier. 本发明涉及枣树栽培技术领域，具体公开种提高枣树嫩枝嫁接成活率的方法，其是用半木质化的枣树发育枝作为接穗，对接穗进行蜡封处理后，嫁接于硬枝上，并在砧木和接穗接口处进行包泥处理。本发明提供的方法成活率高、木质化程度好，将嫁接期从五月下旬延长至7月底，并可使枣树提早年结果。
