摘　　要：西洋参育苗密度效应对1年生苗影响不明显,而对2年生苗影响显著:随着密度的增大,叶面积变小,参茎增长,参根细短;种植密度越大,冠干重,根干重及其经济系数也相应降低。应根据栽培制选定合理密度。It has been found that the effect of planting density is hardly noticeable for one-year-old seedlings, but very apparent for 2-year-old ones. With the increase of planting density, the leaf area gets smaller, stem higher, and root thinner and shorter. The larger the planting density. The smaller the dry weights of canopy and root and the root-canopy ratio. It is thus advocated that rational planting densities be selected according to the proper cultivation systems.
