| 摘 要： | 对浙江雪胆各器官主要金属元素分布及其与土壤养分之间的关系进行了研究,结果表明,1)浙江雪胆原生土壤中Fe元素的含量最高,其次是K元素,Mn和Zn含量较低;2)植物的各器官中,均以K元素含量最高,其次是Ca和Mg,微量元素Fe、Mn和Zn含量均相对较低;3)Fe、Mn和Zn 3种微量元素均以根中含量为最高,Mg和Ca元素均以块茎中较高,K则以叶中最高;4)同一器官元素分布均呈正相关,而不同器官之间的元素分布整体上呈负相关;5)根中Mg、K和Ca均与土壤元素含量整体上呈负相关,块茎中元素均与土壤元素含量均呈正相关,叶中除Fe元素外,其他元素均与土壤元素含量均呈负相关;6)各器官大量元素的富集系数较高。
