摘要
通过选择确定7种桉树品系在永泰县三个不同海拔带,采用随机区组,3个重复设计,运用双因素方差分析方法进行造林对比试验研究。结果认为7种桉树品系在本区表现良好。分析表明不同桉树品系间在胸径、树高、蓄积量生长方面均存在显著差异。不同海拔对桉树的胸径生长无显著影响,但对树高及蓄积量生长影响显著。桉树不同品系与造林地不同海拔的交互作用对胸径生长无显著影响,但对树高、蓄积量生长影响显著;尾赤桉201生长最优,其次是尾园桉184和尾巨桉3229。
Seven varieties of eucalypt selected were introduced at three altitude levels in Yongtai with randomize blocks design contained 3 repeats, and the results of comparative test on their afforestation were analyzed by the methodology of "analysis of dual - factor variance". The results were showed that:the eucalypt introduced were growing well, there were some differences between their DBH, tree height and volume, and different altitude levels showed no apparent effect on eucalypt DBH growth, but marked effect on tree height and volume. The interaction of altitude level and variety also showed the same effect on DBH and tree height and volume. E. urophyllax camaldulensis 201 growth was best, the next was E. urophylla x E. tereticonais 184 and E. urophylla x grandis 3229.
