| 摘 要： | 以红锥（Castanopsis hystrix）、米老排（Mytilaria laosensis）2种广西乡土阔叶树种为混交树种,对不同混交模式下桉树与红锥、米老排的林木生长情况进行了分析。研究结果表明：在桉树与米老排（3∶1）混交模式下,桉树树高、胸径生长量明显高于桉树纯林。而混交模式下,红锥生长量增加,而米老排生长量降低。初步认为,混交能促进桉树生长,但最佳混交造林模式因混交树种而异。

| Abstract: | Growth of eucalypt,Castanopsis hystrix and Mytilaria laisensis in different patterns of mixed forests was analyzed using two native broadleaved tree species,C.hystrix and M.laosensis of Guangxi as mixed tree species.The results showed that tree height and DBH of eucalypt from mixed plantations of eucalypt and C.hystrix（3∶1） were significantly greater than that from pure eucalypt plantations.The growth of C.hystrix increased,while that of M.laosensis decreased in the condition of mixed planting.In preliminary conclusion, mixed planting was able to promote the growth of eucalypt,but the optimal pattern of mixed planting depended on mixed tree species. |
