| 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18 000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; 15 cm根茎长度处理下的巫山淫羊藿分枝数明显高于其它组; 5 cm深度处理有利于巫山淫羊藿叶生长,20 cm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。 |

| Abstract: |
| 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 1 800 plants per hectare treatment. It developed more branches with 15 cm rhizome length of E.wushanense than other groups. And while the cultivation in 20 cm depth promoted the stem growth,the leaf growth were accelerated under 5 cm 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. |
