摘　　要：3个桉树无性系在相同立地条件下的造林对比试验的研究结果表明,3个桉树无性系在胸径、树高、蓄积量生长方面均存在显著差异,适宜本区发展的无性系为尾巨桉3228和尾巨桉3229,而尾叶桉U6生长较差;从效益分析来看,采用尾巨桉3228和尾巨桉3229造林比尾叶桉U6造林具有明显的优势。Studied on the contrast afforestation experiment of 3 Eucalyptus clones the same site conditions. The results showed that 3 Eucalyptus clones grew well in this area. There were significant discrepancies between the 3 Eucalyptus clones in DBH, height or volume respectively. The best clones suitable for development in this area were E. urophylla x E. grandis 3228 and E. urophylla x E. grandis 3229, the next is E. urophylla U6. From the economic benefits, E. urophylla x E. grandis 3228 and E. urophylla x E. grandis 3229 were obvious super than E. urophylla U6.
