摘要
在相同立地条件下对广西钦州地区5年生的5个桉树无性系进行生长对比试验,结果表明:5个无性系在树高、胸径、蓄积量生长方面差异均达到显著水平;广林韦赤桉(Eucalyptus wetarensis×E.camaldulensis)3号和广林柳窿桉(E.saligna×E.exserta)9号蓄积量占有较大的优势;无性系生长表现由好到差依次为:广林韦赤桉3号>广林柳窿桉9号>广林巨尾桉(E.grandis×E.urophylla)9号>广林柳窿桉1号>广林巨尾桉5号。
Study on the growth comparison among five 5-year-old Eucalyptus clones in the same site conditions was conducted in Qinzhou Region of Guangxi.The result showed that there were significant differences in tree height,DBH and the volume among 5 Eucalyptus clones.In terms of tree volume,E.wetarensis×E.camaldulensis NO.3 and E.saligna×E.exserta NO.9 were better than GL-9.The growth performance of 5 Eucalyptus clones was as follows： E.wetarensis×E.camaldulensis NO.3 E.saligna×E.exserta NO.9E.grandis×E.urophylla GL-9E.wetarensis×E.camaldulensis NO.1E.grandis×E.urophylla GL-5.
