| 摘 要： | 在培育森林的实践中,早在19世纪就发现有一些树种对于另一些树种具有选择性的影响,这方面大量的工作是通过叶子、树皮或凋落物等浸出液来进行,而我国则研究甚少,尤其树木间相互影响的研究更少。但是,这种现象却是常见的。如在东北的阔叶红松林中,红松(Pinus koraiensis)常与其他伴生的阔叶树混生一起,不仅生长很好,而且还可以在这些阔叶树林冠下更新成长。相反地,在红松纯林下红松幼苗一般很难维持到10年以上。为了了解这些现象,我们选取我国东北分布最广,经济价值最高的阔叶红松林的

| Abstract: | Tilia amurensis and Fraxinus mandshurica are mainly natural associated tree species in Pinus koraiensis stands, Pinus koraiensis trees often develop into stand under the crown of these broadleaved trees.Therefore, study on the influence of mainly associated tree species on the growth of Pinus koraiensis is very important for understanding the community function of these tree specie and properly selecting associated tree species in building mixed forest of Pinus koraiensis. A lot of pot incubation tests were conducted in this study, in which Pinus koraiensis seedlings were incubated with leaf extracts of Tilia amurensis, Fraxinus mandshurica, Picea koraiensis, Pinus koraiensis or their leaf powder mixed in pot soil. Experimental results showed that leaves of Tilia and Fraxinus broad-leaved species could promot the growth of Pinus koraiensis seedlings obviously in comparison with needles of Pinus koraiensis and Picea koraiensis. For this reason, Tilia and Fraxinus were suggested as important associated tree species in planting Pinus koraiensis coniferous-broadleaved forest. |
