Methods of cultivating robust secondary branches and fruiting mother branches of young trees in summer pruning

First of all, the jujube heads of the central dry jujube and the main side branches were retained, and the rest of the sprouting jujube heads were sprouted as early as possible; the left jujube heads were coring after leaving 4 to 8 secondary branches according to the growth situation. After the jujube head basically stops growing, it is generally carried out from July to August to open the angle. The retention of jujube heads should be well controlled when cutting in summer, generally 4 to 6 2-3-year-old trees and 7-10 4-6-6-year-old trees. When there is a certain amount of branches, armour can be opened to promote the results.
