摘要
比较桢楠纯林造林和在桉树林下间种的幼林生长量,结果表明,随着生长期的增加,桢楠的树高和地径增长变化达显著水平以上,但纯林造林的增长幅度远大于桉树林下间种,2年生纯林下坡位桢楠平均树高达203.6cm,平均地径达2.6cm。而桉树林下间种的平均树高只有72cm、平均地径0.7cm。综上表现,桢楠纯林造林比在桉树林下间种生长快。
This paper compares Phoebe zhennan.young forest growth of purebreed planting and interplanting in Eucalyptus.The results showed that with the increase of the growing season,the height and the diameter growth of Phoebe zhennan.were above the significant level.However,the growth rate of pure forest afforestation is much greater than that of interplanting in Eucalyptus,2a downhill trees of purebreed planting average height was 203.6cm,and average ground diameter of them was 2.6cm,by the interplanting in Eucalyptus 2a downhill trees average height was only 72 cm and ground diameter was 0.7cm.The results showed that Phoebe zhennan grouth faster in purebreed planting than interplanting in Eucalyptus.
