以毛竹林冠下种植的多花黄精根茎繁殖苗为研究对象,探讨不同海拔梯度(150~300、300~450、450~600、600~800、800~1000、1000~1200 m)对多花黄精生长及多糖含量的影响。结果表明:不同海拔梯度对多花黄精生长影响较为显著,多花黄精的生长量和多糖含量随海拔升高呈逐渐下降趋势,以海拔150~600 m范围内多花黄精的生长量和根茎质量较高,2年生多花黄精的保存率、地径、高度、根茎总产量、根茎多糖含量的平均值分别达91.6%、0.57 cm、62.5 cm、6109.29kg·hm-2、13.5%;选择海拔600 m以下区域范围内的毛竹林冠下种植多花黄精较适宜。研究结果对多花黄精最适栽培区域选择具有一定参考价值。
In order to study the effects of different altitudinal gradients (150-300, 300-450, 450-600, 600-800, 800-1000 and 1000-1200 m) on the growth of polygonatum Growth and polysaccharide content. The results showed that the effects of different altitudinal gradients on the growth of Polygonatum sibiricum were significant. The growth and the content of polysaccharides of Polygonatum sibiricum showed a decreasing trend with the increasing of altitude. The growth of Polygonatum sibiricum and the quality of rhizome The average values of preservation rate, diameter, height, total rhizome yield and polysaccharides content of two-year-old Polygonatum reached 91.6%, 0.57 cm, 62.5 cm and 6109.29 kg · hm-2, respectively, 13.5% Under 600 m below the scope of the crown of bamboo canopy planted Polygonatum more appropriate. The research results have certain reference value for the selection of the best cultivation area of Polygonatum.
