分别测量与分析了红豆树立木的胸径、树高、枝下高、胸高心材比率、枝粗系数、树干通直度系数、枝下高系数等13个性状特征及其变异程度,及各主要性状间相关关系进行了探讨。结果表明,材积生长与胸径、冠长、Ⅰ级侧枝粗度、树高、枝角、通直度呈极显著正相关,与枝下高呈显著相关。红豆树材用性优树选择因子的重要性序列为:胸径、枝下高、树高和胸高心材比率;枝下高与通直度可择其一作优树选择的评价指标;枝粗系数可作为红豆树干材的形质控制指标。
Thirteen traits such as DBH, height of tree, height of branch, ratio of heartwood to heartwood, coefficient of branch thickness, trunk straightness coefficient and branch height coefficient were measured and analyzed. And the main characters The correlation between them is discussed. The results showed that there was a significant positive correlation between volume growth and DBH, crown length, grade Ⅰ collateral roughness, tree height, branch angle and straightness, and significant correlation with volume. The order of the importance of the selection factors for the superiority tree selection of red bean is as follows: the diameter of the breast, the height of the branch, the ratio of the tree height and the height of the heartwood; the index of branch height and straightness can be selected as the evaluation index of superior tree selection; As a red bean trunk shape control index.
