山楂的结果母枝除按长度分为5厘米以下短结果母枝、5～15厘米中结果母枝和15厘米以上长结果母枝三类外,尚可依山楂自身特点区分为交替结果的具顶芽(叶芽或混合芽)的结果母枝和连续结果的无顶芽的结果母枝。5厘米以下的结果母枝结果能力差,多分布于内膛,5厘米以上的结果母枝、连续性结果母枝结果能力好,多分布于树冠外围。山楂以5厘米以下短结果母枝为主,一般占单株结果母枝总数50％以上。山楂结果母枝的发生与树势密切相关,增强树势可提高单株结果母枝总数、5厘米以上结果母枝和连续结果母枝数量;而5厘米以下结果母枝和交替性结果母枝相应减少。
Hawthorn results in addition to the mother tree by length divided into 5 cm below the short fruiting branches, 5 to 15 cm in the results of the mother and 15 cm longer than the mother of the three branches, but also according to their own characteristics of hawthorn can be divided into alternating results with Results of the terminal buds (leaf buds or mixed buds) The result of the parental shoots and the continuous shoots of the non-terminal buds. 5 cm below the result of poor performance of the parent branch, and more distributed in the bore, 5 cm above the results of the parent branch, the result of continuity of the parent results are good, and more distributed in the crown periphery. Hawthorn to 5 centimeters below the main result of the short main branches, generally accounted for more than 50% of the total number of single branches. The occurrence of hawthorn parent is closely related to the tree vigor. Increasing the tree vigor can increase the total number of fruit trees per plant, the number of fruit trees more than 5 cm and the number of continuous fruit trees, while the number of fruit trees and alternate fruit trees below 5 cm Reduce accordingly.
