[目的]研究浙贝及土壤中无机元素的含量，探讨根际土与浙贝鳞茎中元素的相关性以及元素对浙贝道地性形成的作用，为浙贝的栽培提供科学理论指导。[方法]采用电感耦合等离子体发射光谱仪（ICP-OES）和微波消解仪测定不同产区、种源和物候期的浙贝及土壤中15种无机元素的含量，并进行聚类、吸收系数和相关性分析。[结果]聚类分析结果表明，浙贝土壤和鳞茎中的元素含量特征主要以产区来划分，说明产区外环境对浙贝母元素吸收的影响大于种源和生长物候期等因子。浙贝鳞茎中重金属元素Pb、Cd的变异系数都较大，微量元素的变异程度比常量元素大。浙贝对P、S、Mg的吸收系数均大于100%为富集元素，而B、Fe、Al等元素的吸收系数均在1%以下为高贫富集元素，说明富含P、S、Mg等元素的土壤可能对浙贝生长有利。相关性分析表明，鳞茎中的B元素与土壤中的B呈现极显著正相关，除此之外，鳞茎中的B与还与土壤中的Ca、Fe、K、Mg、Mn、Zn、Cr等呈极显著正相关；而鳞茎中的Cu、Cd等重金属与土壤中的元素大部分呈显著负相关，说明这些元素之间会相互作用，或促进或拮抗，从而影响植物的生长。[结论]产区环境对浙贝母元素特征的影响效果大于种源及物候期的影响，浙贝鳞茎中元素与土壤中的元素关系复杂，其中鳞茎中的B、Cu、Cd与土壤元素关系密切而复杂，在研究和栽培中值得进一步关注。
[目的]研究浙貝及土壤中無機元素的含量，探討根際土與浙貝鱗莖中元素的相關性以及元素對浙貝道地性形成的作用，為浙貝的栽培提供科學理論指導。[方法]採用電感耦閤等離子體髮射光譜儀（ICP-OES）和微波消解儀測定不同產區、種源和物候期的浙貝及土壤中15種無機元素的含量，併進行聚類、吸收繫數和相關性分析。[結果]聚類分析結果錶明，浙貝土壤和鱗莖中的元素含量特徵主要以產區來劃分，說明產區外環境對浙貝母元素吸收的影響大于種源和生長物候期等因子。浙貝鱗莖中重金屬元素Pb、Cd的變異繫數都較大，微量元素的變異程度比常量元素大。浙貝對P、S、Mg的吸收繫數均大于100%為富集元素，而B、Fe、Al等元素的吸收繫數均在1%以下為高貧富集元素，說明富含P、S、Mg等元素的土壤可能對浙貝生長有利。相關性分析錶明，鱗莖中的B元素與土壤中的B呈現極顯著正相關，除此之外，鱗莖中的B與還與土壤中的Ca、Fe、K、Mg、Mn、Zn、Cr等呈極顯著正相關；而鱗莖中的Cu、Cd等重金屬與土壤中的元素大部分呈顯著負相關，說明這些元素之間會相互作用，或促進或拮抗，從而影響植物的生長。[結論]產區環境對浙貝母元素特徵的影響效果大于種源及物候期的影響，浙貝鱗莖中元素與土壤中的元素關繫複雜，其中鱗莖中的B、Cu、Cd與土壤元素關繫密切而複雜，在研究和栽培中值得進一步關註。

[Objective]To explore the elemental relevance between the rhizosphere soil and the bulbs of Fritillaria Thunbergii as wel as their functions in the geoherblism formation, we detected the content of inorganic elements in bulbs of F. Thunbergii and its rhizosphere soil. [Method] We measured the content of 15 kinds of inorganic elements with inductively coupled plasma optical emission spectrometer(ICP-OES) and microwave digestion system in soil and F. Thunbergii which was col ected from different producing areas, provenances and growth periods and analyzed the data with clustering analysis, absorption coefficient and correlation analysis. [Result] Clustering analysis results showed that elemental content in soil and bulbs was mainly distinguished by producing areas, which indicated the environments rather than provenaces areas and growth periods affected the elements absorbtion of F. thunbergii. The coefficient of varation(CV) of Pb and Cd in bulbs was higher than others ’and the variation of microelement is larger than that of macroelement. P, S and Mg were the enriched elements for their absorption coefficient over 100%, while those of B, Fe and Al below 1%were absorbed less, which indicated that element P, S and Mg enrichening in the soil might be beneficial to the growth of F. thunbergii. The correlation analysis showed that B in soil had a significant positive correlation with that in bulbs. Moreover, element B in bulbs was positive correlated with elements Ca, Fe, K, Mg, Mn, Zn and Cr in the rhizosphere soil, meanwhile Cu and Cd in the bulbs showed negative correlations with most elements in soil. These interactions among elements could final y influence the growth of plants.[Conclusion] The environments of producing areas has more marked effect on elements than that of provenances and phenological period. Some elements such as B, Cu and Cd need further investigation since these elements in F. thunbergii are closely related to those in the rhizosphere soil.
