摘要
沙棘是阳性树种,通过风、鸟、兽等传播,首先侵入,然后占领地盘,大量萌生形成团块或片状沙棘林,随之从中间开始稀疏死亡,逐渐退出,土壤得到改良肥化,被其他树种侵入代替,再通过风、鸟、兽等传播,侵入新的地点,形成新的沙棘林分,重复以上演替过程。
Hippophae rhamnoides Linn.is heliophilous tree and invades first through wind blowing,birds and animals and then begins to reproduction by cluster shooting followed by dying in the middle of the cluster and being replaced by other invaded plants.Through the process,the soil is improved and new community of Hippophae rhamnoides Linn.will be re-formed.
