摘  要：
将磷肥、尿素和桉树专用肥3种肥料分为3个水平,对4个不同初植密度广林9号桉树幼林进行施肥处理。采用方差分析方法分析了不同施肥处理及不同初植密度对桉树幼林生长的影响。结果表明:不同施肥种类及施肥量对广林9号桉幼林生长差异显著,桉树专用肥的影响极显著,尿素影响显著,磷肥影响不显著,其中尿素随施用量的增加对苗木生长存在抑制作用;桉树专用肥随施用量的增加对苗木生长有明显促进作用。不同初植密度的1年生广林9号桉幼林生长差异不显著。

摘  要：
36 treatment combination trials of 3 kinds of fertilizers(urea,phosphate fertilizer and special eucalyptus fertilizer) and 4 planting densities were carried out to identify the different effects on growth of young Eucalyptus GL9 stands with different fertilizers and initial planting densities.The results were as followed: there were significant differences in growth of GL9 young stands between different fertilizers and different fertilizer amounts.Special eucalyptus fertilizer high significantly influenced trees growth,urea significantly influenced trees growth and there was no significant influence by phosphate fertilizer.There was an increasing inhibition on seedling growth with an increasing amount of applied urea.There was an obvious promotion to seedling growth with an increasing amount of applied special eucalyptus fertilizer.There was no significant effect on 1-year-old GL9 trees growth among different initial planting densities.
