| 摘 要： | 对宁夏中宁县、平罗县两地枸杞中铜、锌、锰、锗、硒、砷等6种微量元素的含量进行了测定，用聚类分析方法对元素含量的综合指标进行了考查和比较研究，结果表明，根据微量元素含量的测定结果，运用聚类分析法能准确快速地区别两地的枸杞，为枸杞道地性质量标准的制定提供了理论依据。

| Abstract: | The contents of Cu, Zn, Mn, Ge, Se and As in wolfberry from Zhongning and Pingluo of Ningxia were determined by AAE in this paper, and made examination and comparative research on the comprehensive index of element contents by cluster analysis. The results showed that the wolfberry of two fields can be distinguished fast and accurately. It would provide the theoretical basis for the establishment of wolfberry quality standard in zonality. |
