| 摘 要： | 红松分杈是红松内在生理因素和外部环境条件共同作用的结果。复层红松混交林和阴坡人工红松林红松分杈率较低。单层红松林高密度，能有效地降低红松多杈株率。红松杈干是主梢受害枯死或断折后，经侧枝的激烈竞争和顶端的驱使下逐渐形成的。

| Abstract: | The forking of Korean pine is caused by both the internal physiological factors and external environmental conditions. The forking ratios of multi-stratum Korean pine mixed forests and north slope Korean pine plantations are the lowest, and single stratum Korean pine forests with high densities can effectively decrease the proportion of forked trees. The fork arm is gradually formed by the fierce rivalry and apical dominance of lateral branches after the main gib is damaged to wither or break. |
