摘　　要：目的：探究微量元素在亳菊不同部位的分布及富集规律。方法：采用微波消解处理亳菊不同部位及根系附近土壤,通过ICP-MS测定,并采用统计学软件对试验数据进行相关性分析。结果：亳菊不同部位及其土壤中8种微量元素含量存在差异;亳菊不同部位对8种微量元素的富集系数存在明显差异,变化范围为0.0054~0.9205;亳菊花序中Fe与Mg呈显著正相关;亳菊花序与土壤中的Fe呈显著正相关,亳菊枝叶与土壤中的Al、Ba和Mg呈显著正相关。结论：亳菊对微量元素的吸收存在选择性,可以通过改善栽培中的部分环节来提高亳菊的质量。Objective： To explore the contents and enrichment status of the trace elements in Boju by using ICP-MS. Methods：Trace elements of the different parts of Boju and the soil near the roots were determined by microwave digestion-ICP-MS and the correlation of the data obtained was tested by using the statistical software. Results： There were differences among the contents of the eight elements in the different parts of Boju and the soil; there were obvious differences in the enrichment factor of eight elements in the different parts of Boju,which ranged from 0. 0054 to 0. 9205; there was a significant positive correlation between Fe and Mg in the inflorescence and the contents of Fe was positively correlated with the soil; for Al,Ba and Mg,there were significant positive correlations between its soil contents and leaves contents. Conclusion： Boju absorbs the inorganic elements selectively,the yield and quality of Chinese medicinal materials can be improved by improving the cultivation.
