摘要
目的 :了解土壤中无机元素对茅苍术道地性的影响。方法 :对不同产地茅苍术根茎及生长地土壤中15种无机元素含量进行测定 ,所得数据用SPSS10 .0软件进行分析比较。结果 :发现道地产区茅苍术药材中镍的平均含量高于其他茅苍术的 3倍以上 ,其对钙的吸收有富集作用 ;相关系数分析表明茅苍术及土壤中无机元素元素的含量不相关。结论 :茅苍术主要是通过主动吸收调控药材中无机元素的含量 ;同时发现茅苍术对铁和铬、铁和汞、汞和铬、砷和铅及钴和锶的吸收积累有很好的协同作用。
Objective: To study the influence of inorganic elements in soil on the geolism of Atractylodes lancea. Method : The concentrations of 15 kinds of inorganic elements of regional A. lancea and their correspondingly soils were determined,and the data were analysed with the SPSS10.0 software. Result: The mean concentration of Ni in geoherbs of A. lancea was 3 times higher than that in the non geoherbs. The accumulation of Ca is high in geoberbs. There is no relationship between the concentrations of inorganic elements in A. lancea and those in their corresponding soil. Conclusion: A. lancea adjusts the concentration of inorganic elements mainly by active absorption, and there are good relationship between the accumulation of Fe and Cr, Fe and Hg, Hg and Cr, As and Pb, Co and Sr.
