摘要: 对尾叶桉(Eucalyptus urophulla)与马占相思(Acacia mangium)不同混交处理3a生林分生长调查结果表明:在相同密度1 727株/hm2时,尾叶桉纯林的平均胸径、树高、单株材积分别为9.27cm,14.50m,0.051 4m3,尾叶桉与马占相思以1∶1.6比例混交,尾叶桉的胸径、树高、单株材积分别为13.50cm,15.97m,0.109 8m3,比纯林高45.6%,10.1%,113.6%; 纯林和混交林林分每公顷蓄积分别为88.83m3和98.00m3,混交林比纯林高10.3%。尾叶桉与马占相思不同混交处理林木胸径、树高、材积生长及径高比均有显著差异。

Abstract: The growth of mixed stand of Eucalyptus urophylla and Acacia mangium with different mixed proportion were investigated in 3 year-old forest.The results showed that in the density of 1727·hm-2,the average DBH,height and single-tree volume were 9.27cm,14.50m,0.0514m3 respectively.And the mixed stand of Eucalyptus urophylla and Acacia mangium has the mixed proportion at 1∶1.6 and the above indexes were 13.50cm,15.97m and 0.1098m3,which increased 45.6%,10.1%,113.6% higher than that of Eucalyptus urophylla pure stand.The mixed stand with 98.00m3/hm2 forest volume was 10.3% higher than the pure stand with 88.83m3/hm2 forest volume.The different mixed treatments have significant difference in the average DBH,height,tree volume and ratio of diameter to height.
