不同种植密度对不出林生长和产量的影响

【目的】研究不同栽培密度对不出林（犃狉犱犻狊犻犪犼犪狆狅狀犻犮犪）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.

Effects of Different Plantation Densities on the Growth and Yield of Ardisia japonica

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 density 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 diameter,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,underground 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.
