摘　　要：测定和比较了3种栽培方式(栽培密度、栽培根茎长度和栽培深度)下巫山淫羊藿叶长、株高、分枝数和花蕾数等生理生长指标,探寻巫山淫羊藿最适生长条件和生长投资策略,为药用淫羊藿人工栽培提供理论基础和实验依据。结果表明:在每平方米18000株的栽培密度下,植株各项生理指标均显著优于其它密度处理;15cm根茎长度处理下的巫山淫羊藿分枝数明显高于其它组;5cm深度处理有利于巫山淫羊藿叶生长,20cm深度处理有利于巫山淫羊藿茎生长。进一步分析表明:栽培密度和栽培根茎长度对巫山淫羊藿营养生长影响较大;栽培深度对植株的营养生长和生殖生长影响都较大。To explore the optimum growth conditions of Epimedium wushanense , the influences of three culturing modes （ planting density , rhizome length , planting depth ） growth of E.wushanense were compared.The experiments were conducted to investigate the plant height , leaf length , branch number , flower buds number and other physiological index.The results indicated that plant density obviously affected the E.wushanense ’ s growth and it was affected significantly under 1 800plants per hectare treatment.It developed more branches with 15cm rhizome length of E. wushanensethan other groups.And while the cultivation in 20cm depth promoted the stem growth , the leaf growth were accelerated under 5cm depth condiction.Further analysis showed that planting density and rhizome length had significant influence on vegetative growth of E.wushanense , and planting depth affected both vegetative growth and reproductive growth of E.Wushanense.
