摘　　要：为优化多花黄精人工栽培模式,评价多花黄精品质,采用田间栽培试验,比较分析了不同栽培模式下土壤养分、多花黄精生物量分配;依据中国药典黄精检测方法,评价不同栽培模式多花黄精品质。结果表明,限耕容器栽培的土壤改良较好,多花黄精生长量较大,黄精多糖含量高,为10.0%;起垄栽培黄精多糖含量为9.4%。相关性分析结果:根系数量、长度与多花黄精根茎直径、鲜重呈显著正相关,在一定范围内,土壤pH值、全磷和全钾含量与黄精多糖含量呈线性正相关。研究表明:与起垄栽培相比,限耕容器栽培的多花黄精产量高10%,黄精多糖高6%,是人工种植较好的选择。This study aimed to optimize the cultivation for Polygonatum cyrtonema Hua.The soil nutrients and the plant biomass distribution under different cultivation methods were compared and analyzed in the field.Quality of the cultivated plants was evaluated using the methods stipulated in the Chinese pharmacopoeia.The results indicated that the root-restricting tillage in a confined container allowed a remarkable soil amelioration as well as a high plant polysaccharide content at 10.0%in comparison to the ridge cultivation at 9.4%.The number and length of roots per plant significantly correlated with the diameter and fresh weight of the rhizomes on a plant.Within a certain range,the pH,total phosphorus and total potassium of the soil linearly correlated with the plant polysaccharides.It appeared that the root-restricting container cultivation could increase the yield by 10%and the polysaccharide by 6%on P.cyrtonema over the ridge-cultivation.
