| 摘 要： | 以刚果１２号桉元性系组培苗为材料，进行４种不同密度和４种不同施肥处理双因素试验，３年生结果表明：不同密度和施肥措施对刚果１２号桉生长有极显著影响，密度效应和施肥效应互作用显著；密度效应较施肥效应大，其方差分量前者约为后者的９倍；密度越大，单株材积越小，但单位面积蓄积越大；不同施肥处理以添加钾肥的明显有利于林木生长。

| Abstract: | The effect of various silviculture treatments on growth were examined at the clonal plantation of Eucalyptus ABL 12. Four different spacings and four fertilizer ratios at two levels were designed for experiment and the result in 3 years showed that the growth was significant response to different spacings and fertilizer ratios. Clear interaction was found between spacing and fertilizer ratio. Spacing effect on growth was greater than that of fertilizer ratio. The more density, the more volume per unit area, the less volume per tree. Fertilizing treatment by the addition of potassium was most favourable for trees growing. |
