摘　　要：刺龙芽喜肥水,在土壤瘠薄、低湿、庇荫或强光下生长不良,所以,应选择林中土壤肥沃、湿润、排水良好、郁闭度在0.2~0.8的林下栽植刺龙芽。栽植后要及时进行杂草防除、防虫、浇水、修剪整枝、合理追肥、适时采收等一系列管理才能确保刺龙芽健康生长。本试验是在郁闭度0.46、0.65和0.75的杨树林下定植,株距80 cm,行距100 cm刺龙芽幼苗,定植当年调查成活率,第二年调查生长情况,经过调查数据统计分析,总结出杨树林下栽植刺龙芽最佳郁闭度。Aralia Elata likes fertilizer and water,and grow poorly under barren soil,low humidity,shade or strong light.Therefore,it should be planted under the forest with fertile soil,moist,and good drainage,with a canopy density of 0.2~0.8.After planting,a series of management,such as weed control,insect control,watering,pruning,reasonable topdressing and timely harvesting,should be carried out in time to ensure the healthy growth of Aralia Elata.This experiment was planted under poplar forest with canopy density of 0.46,0.65 and 0.75,with plant spacing of 80 cm and row spacing of 100 cm.The survival rate was investigated in the same year and the growth situation was investigated in the second year.After statistical analysis of the investigation data,the best canopy density for planting poplar forest was summarized.
