摘　　要：对3.5年生的大花序桉纯林、大花序桉+红椎混交林、大花序桉+火力楠混交林、红椎纯林和火力楠纯林的生长量进行分析。结果显示:混交模式下,大花序桉、红椎、火力楠的胸径、树高均高于纯林模式下相应树种,相比纯林中相应树种分别提高1.90%和11.96%、36.17%和4.26%、12.73%和2.27%。其中以大花序桉+红椎(9:3)和大花序桉+火力楠(8:2)的配置模式效果最好。The growth of 3.5-year-old plantations of pure Eucalyptus cloeziana,mixed E.cloeziana and Castanopsis hystrix,mixed E.cloeziana and Michelia macclurei,pure C.hystrix and pure M.macclurei were analyzed.Results showed that the DBH and height of E.cloeziana,C.hystrix and M.macclurei in mixed plantations were obviously higher than those of the same species grown in pure forests,with increases of 1.9%and 12.0%,36.2%and 4.3%,12.7%and 2.3%respectively.The ratio of 9:3 for E.cloeziana and C.hystrix and 8:2 for E.cloeziana and M.macclurei proved to be the optimal mixtures for growth.
