摘  要:
针对史密斯桉造林密度与施肥模式进行了研究,对试验地设置3种造林密度作主区,4种施肥模式作副区。对17个月生史密斯桉的试验调查进行分析,结果表明:造林密度对树高生长量的影响差异不显著,而对胸径影响差异显著,适宜密度为2 000株·hm-2。施肥对史密斯桉幼树树高、胸径生长的影响极显著,不同的施肥模式对史密斯桉幼林生长的效果是:桉树专用肥>复混肥+微肥>复混肥+磷肥+微肥>复混肥+磷肥。

摘  要:
To examine the effects of plantation density and fertilizer composition on growth of Eucalyptus smithii, three plantation densities were trialed as main effects with four fertilizer compositions applied as secondary treatments in sub-plots. Growth of the trial was assessed at age 17 months after planting. Plantation density had no significant effect on tree height, but did have a significant effect on DBH with the optimum density for this trait being 2000 trees per hectare. The composition of applied fertilizer had highly significant effects on both height and DBH of young trees, with the growth ranked by fertilizer composition being as follows: Eucalyptus special fertilizer > compound plus trace element fertilizer > compound plus phosphate plus trace element fertilizer > compound plus phosphate fertilizer.
