摘　　要： 龙牙楤木幼树的树高、高生长和地径,与根系处理、栽植密度和施肥关系密切.GGR溶液可促进龙牙楤木新根的萌发和不定芽的形成,促进其高生长和地径生长;适宜的初植密度可增加龙牙楤木幼龄林早期产量,2株/穴是营造经济林高产较合理的密度;合理施肥可以促进龙牙楤木幼树高生长和地径生长,尿素15g/株+磷酸二铵10g/株+氯化钾6g/株的氮磷钾混合施肥效果比较理想. Aralia elatatree height,height growth and diameter and root treatment,planting density,fertilization is closely related to.GGR solution can promote the Aralia elata germination and adventitious bud formation,promote its high growth and diameter growth,the suitable planting density can increase the early yield of Aralia elata plantation,2plants/hole is to create economic yield more reasonable forest density;rational fertilization can promote seedling height and stem growth.15g/plant of urea＋ diammonium phosphate 10g/plant＋potassium chloride 6g/plant mixed application of nitrogen,phosphorus and potassium is ideal.
