| 摘 要： | 研究了不同施肥处理对６ ａ 生尾叶桉单株材积、年轮宽度、密度的影响规律，结果表明：从髓心向外，６ ａ 生尾叶桉年轮宽度呈逐渐减小趋势，基本密度呈逐渐上升趋势；施肥处理可以显著加快６ ａ 生尾叶桉的生长速度，提高尾叶桉的生长量；而造林当年施肥不仅加快尾叶桉当年的生长速度，对后期生长也有较好的促进作用；各施肥处理与对照材木片密度无显著差异。

| Abstract: | In order to investigate the effects of fertilization treatments on wood quality of Eucalyptus urophylla ,this paper deals with volume,growth ring width and gravity of 6 year old E. urophylla .The results are as follows:(1)Growth ring width increases gradually and basic gravity decreases gradually with the increase of growth ring age.(2)Fertilization treatments may significantly promote the growth of 6 years old E. urophylla ;while fertilization treatments of first year not only promote the growth of that year,but also have positive effects on the later growth.(3)Fertilization treatments have no significant effect on average gravity. |
