对于平顶松的枝条修剪该如何是好
- 2019-01-11-

       平顶松的枝条,按性质可分为营养枝和开花枝。营养枝以营养生长为主,就是一般意义上的枝条.是苗木修剪的主要对象。依其生长情况可分为生长枝、徒长枝和短弱枝。充实的生长枝可成为苗木的骨干枝,钩成树身和树冠。生长枝也可培育成开花枝。

       徒长枝与生长枝相比,生长旺盛,节间长,芽较小,叶形大而薄,组织疏松,在生长过程中会与生长枝争夺养分与水分,影响生长枝的正常生长,所以在平顶松松基地进行修剪时要及时剪去。但徒长枝有时也因可替代主枝缺损,填补树冠空缺或作为老树的更新复壮而加以保留。

       短弱枝多生长在树冠内、阳光不足的部位,或枝条下端。短弱枝外形细弱短小,叶亦小、过多时应适当剪除疏去。
