摘　　要：以林木生长所需的3种N、P、K大量元素作为肥料养分组成,设计5种不同施肥处理(含对照)对柳窿桉(Eucalyptus saligna×E.exserta)无性系进行施肥试验。通过对试验林8、21、30个月生时的林木生长调查数据分析,结果表明,施肥可显著促进柳窿桉林木树高、胸径、单株材积的生长,但不同施肥量处理的树高生长没表现出显著差异,而不同施肥量处理间的胸径、单株材积生长差异明显,即施肥量大的处理的胸径、单株材积生长效果要显著优于施肥量小的处理。The fertilization experiment which designed five different fertilization treatments（including control treatment） by applying N,P and K as composition of fertilizer nutrient was conducted in Eucalyptus saligna × E.exserta clones of Huaqiao forest farm.The investigation datas on the growth of 8-month-old,21-month-old and 30-month-old plantations were analyzed and the results showed that fertilization significantly increased tree height,DBH and individual volume.The tree height showed no significant difference among the trees treated by different fertilizations.While the differences of DBH and individual volume were significant,which the growth of DBH and individual volume with more fertilization was better than that with less.
