The pruning method of the trunk sparse layer tree from the first to the first year

The purpose of pruning in this period is to cultivate the main branches of the third and fourth layers. The culture method is the same as that in the fifth to sixth years, and the distance between layers can be appropriately smaller, about 60 centimeters. At the same time, one or two lateral branches are cultivated for the first and second layers of main branches, and the cultivation of lateral branches is the same as that of happy ones. With the growth of the tree, the amount of jujube loaded on the central leading trunk increases, so it no longer extends upward, changes and droops during natural growth, generally does not need to be cut off manually, and it is no longer necessary to artificially increase the upright branches of the culture center. In order to facilitate ventilation and light transmission, 8 years later for the natural formation period, the natural formation period to about 15 years, the formation of a complete natural happy tree.
