摘要：在贫瘠低丘上对刚果１２号桉进行不同肥料配合和不同用量的施肥试验，结果表明，ＮＰＫ、ＮＫ、ＮＰ和ＰＫ配合施用的能极显著地促进刚果１２号桉的生长，５年生时蓄积比对照分别增加１９．４０，１８．４５，１６．４０，１５．０５ｍ３／ｈｍ２，Ｎ、Ｐ、Ｋ肥单施的蓄积比对照分别增加５．３０，５．２５，４．８０ｍ３／ｈｍ２；肥料的配合施用极显著地优于Ｎ、Ｐ、Ｋ单施；材积的增长量随施肥量的增加而增加。
Different amounts and fertilizers were applied to the trees of Eucalyptus ABL 12 on poor low hilly land. The results showed that NPK, NK, NP and PK increased the tree growth of E . ABL 12 significantly and stand volumes of the 4 treatments were 19.40, 18.45, 16.40 and 15.05 m 3/hm 2 more than the control respectively. The another 3 treatments applied with N, P and K were 5.30, 5.25 and 4.80 m 3/hm 2 more than the control. This indicated that compound fertilizers were much better than fertilizers with single element. Stand volume was increased while the amount of fertilizers applied increased.
