【目的】研究不同栽培密度对不出林（Ardisia japonica ）生长和产量的影响，为不出林人工栽培提供理论依据。【方法】以不出林为材料，研究6种不同栽培密度下不出林的形态、生物量及其分配指标的变化特征。【结果】除平均根长外，不同栽培密度对不出林单株的株高、地径、分株数、叶片数和根数均影响不显著；不出林根冠比和比根长均随栽培密度的增大而显著降低；随着栽培密度的降低，不出林单株地下部分鲜干重、地上部分鲜干重和总鲜干重均显著增大，但每小区总鲜干重显著减小。【结论】10cm×10cm栽培密度的不出林产量最高。

Objective]The aim was to study effects of different plantation densities on growth and yield of Ardisia japonica,a kind of Chinese herbal medicine,find out the suitable densi-ty for the planting of Ardisia japonica,and provide reference for high yield and quality Ardisia japonica plantation.[Methods]the morphological properties,biomass and biomass allocation characteristics of Ardisia japonica planted in six different densities were studied.[Results]The result showed that density didn’t significantly affect the plant height,bisal di-ameter,branch number,leaf number and root number,except the average root length.With the decrease of light intensity,the root mass/crown mass ratio,specific root length,under-ground fresh and dry weight,aboveground fresh and dry weight,and total fresh and dry weight of Ardisia japonica increased significantly,but the total fresh and dry weight of per block decreased significantly.[Conclusion]10cm × 10cm is the optimal planting density for Ardisia japonica .
