[目的]为了探明库尔勒香梨树冠内各类枝的分布及结构特征,[方法]采用树冠分格法,统计分析每个立方格内各类枝的数量及分布特征。[结果]结果表明:疏散分层形骨干枝总数为97枝,主要分布在下层与中部,开心形的骨干枝总数为94枝,主要分布在下层与中部;疏散分层形一年生枝总数为3920枝,主要分布在中层与外围,开心形一年生枝总数为3183枝,主要分布在中层与外围;疏散分层形的多年生枝总数为2184枝,主要分布在下层与外围,开心形多年生枝总数为1444枝,主要分布在中层与外围。[结论]库尔勒香梨两种树形结构,骨干枝数量与主要分布部位基本相同,一年生枝总数差异明显,但主要分布部位相同,多年生枝数量与主要分布部位均差异明显。
[Objective] The research aimed to find out the distribution and structural characteristics of various branches in the crown of Korla fragrant pear. [Method] The crown branching method was used to statistically analyze the quantity and distribution characteristics of various branches in each cube. [Results] The results showed that the total number of branches with scattered stratified branches was 97, mainly distributed in the lower and middle parts. The total number of the trunk branches with happy heart shape was 94, mainly distributed in the lower and middle parts. The total number of annual branches with scattered stratification was 3920 Branches, mainly distributed in the middle and the periphery, the happy annual number of annual branches of 3183, mainly in the middle and periphery; the number of perennial branches evacuated stratified shape is 2184, mainly distributed in the lower and the periphery, the total number of happy-shaped perennial branches is 1444 branches, mainly in the middle and periphery. [Conclusion] There were two kinds of tree structure of Korla fragrant pear with the same number of branches and branches as the main distribution parts. The total number of branches in one year was obviously different, but the main distribution parts were the same, the number of perennial branches and the main distribution parts were all significantly different.
