枝系构型中的化感塑造作用

The Allelopathy in Branching Architectures

同一种树木,长在密林中和长在林外,树形非常不同。通过理论分析提出树冠枝系构型的化感塑造作用,认为枝叶释放挥发性化感物质,抑制叶芽萌发,压弯树干和冠底层侧枝,从而清理树冠内膛、自然修剪侧枝,改善树冠形态,适应林内林外生境,对树冠所在光照空间的利用达到最大化。

The same kind of tree,growing in dense forest and growing outside the forest,has very different shapes.Through theoretical analysis,the allelopathic shaping effect of tree crown branch configuration was proposed.It is believed that the branches and leaves release volatile allelopathic substances,inhibit the germination of leaf buds,and press down the trunk and crown bottom lateral branches,so as to clean the interior of the tree crown,trim the lateral branches naturally,improve the crown form,adapt to the habitat in and out of the forest,and maximize the utilization of the light space where the tree crown is located.
