The method of jujube stem determination

The drying methods of jujube trees are cleaning and cutting drying. ⑴ dry cleaning method: remove the secondary branches and low developmental branches from the trunk every year, the dry height is no more than 1/3 of the tree height, and finally leave a dry height of 1 meter. It is suitable for varieties with weak tree potential, medium branching ability, open tree shape and easy shaping and pruning. ⑵ truncation method: first determine the plastic band of the first layer of main branches cultivated at 4 to 5 segments above the fixed stem height, cut off the above part, leave 1 to 2 nodes at the base of the secondary branches in the plastic band, and remove all the lower ones. The secondary branches in the plastic belt are heavily cut, so that the main branches are drawn from the secondary branches as much as possible, and the opening of the main branches is enlarged, which is beneficial to the early formation of young trees.
