山西省野生黄精资源调查

Investigation on the Resources of Wild Polygonatum sibiricum Red in Shanxi

目的调查山西省野生黄精分布状况及资源特点。方法采取资料收集、野外调查和实地走访等方法对山西省野生黄精资源进行收集整理分析。结果野生黄精资源全面覆盖山西省11个市,遍布50个县,吕梁和运城分布县域较多;海拔分布差异较大,344~2500 m均有涉及,主要集中在1100~2300 m;生长环境以草丛、山坡阴处、林下和灌木丛为主;叶片、果实和根茎形态存在差异:晋南部地区黄精叶、果整体比晋北地区偏大。其中,朔州叶长和叶宽均值最小,运城果实呈“圆球”形,大同果实偏“矮胖”,太原果实偏“瘦高”。结论山西省野生黄精资源集中分布在晋中和晋南地区,受地域影响,黄精之间形态特征存在较大差异,其潜在开发和利用价值较高。

Objective To investigate the distribution status and resource characteristics of wild Polygonatum sibiricum Red in Shanxi.Methods Data collection,field survey and field visits were used to collect and analyze wild Polygonatum sibiricum Red resources in Shanxi.Results The wild Polygonatum sibiricum Red resources covered 11 cities and 50 counties in Shanxi,with more counties in Lyuliang,Jincheng and Yuncheng.The altitudinal distribution varied widely,from 344-2500 m,mainly in 1100-2300 m.The habitats were mainly grasses,shady places on mountain slopes,forest understory and bushes,with a few in rare places such as mountain tops,cliff bottoms and valleys.The leaves,fruits and rhizomes.There are differences in leaf,fruit and rootstock morphology,Shuozhou has the smallest leaf length and width.Yuncheng has“round ball”shaped fruits,Datong has“short and fat”fruits and Taiyuan has“thin and tall”fruits.Conclusion The morphological characteristics of wild Polygonatum sibiricum Red resources in Shanxi,which are concentrated in Jinzhong and south of Shanxi Province,are greatly different from each other due to the influence of regional Cyperus rotundus,and its potential development and utilization value need to be studied.
