摘要
为了探索华南地区桉树人工林混交林模式,本研究以大花序桉和闽楠为混交树种,对3种不同混交模式下3.5年生大花序桉和闽楠的林木生长情况与大花序桉、闽楠纯林进行分析和比较。研究表明:一定比例的混交配置模式下大花序桉和闽楠的的生长量均高于纯林模式下相应树种的生长量,其中以大花序桉+闽楠(9:3)的混交模式效果最好,大花序桉+闽楠(2:1)的混交模式效果次之。
In order to explore growth of Eucalyptus in mixed species plantations in southern China,this study examined mixed species plantings of Eucalyptus cloeziana and Phoebe bournei,and analyzed the growth of 3.5 years of trees of these species under three different mixture patterns compared to growth in plantings of pure E.cloeziana and of pure P.bournei.The results showed that the growth of E.cloeziana and P.bournei in a certain mixed proportion was higher than that of the corresponding tree species pure forest patterns,and a mixed pattern of E.cloeziana+P.bournei(9:3)had the best effect,followed by the mixed pattern of E.cloeziana+P.bournei(2:1).
