摘要
目的:研究川党参元素含量特征和影响元素含量的因素。方法:元素含量测定和统计分析相结合。结果:川党参植物元素含量的RSD低于其土壤中相应元素含量的RSD,不同产地川党参植物元素含量的RSD均小于50%。元素在川党参植物体内分布存在差异。结论:川党参对营养元素的吸收与土壤养分含量、状态以及气候条件等因素有关,对元素的吸收存在元素间的协同或拮抗作用。
Objective： To study the characteristics of element contents and the influencing factors in Codonopsis tangshen. Method： The contents of elements were determined and the data was statistically analyzed. Result： The variation coefficients of elements in C. tangshen were lower than those in soil, and variation coefficients of C. tangshen from different habitats were lower than 50%. Conclusion： The absorption of nutritional elements in C. tangshen was related to content and condition of soil nutrients, and climate etc.
