摘要(Abstract):

目的:测定人工栽培与野生夏枯草土壤及其植株各器官矿质元素含量,以期为该资源保护利用及GAP研究提供理论依据。方法:运用ICP-AES法测定栽培与野生夏枯草各器官及其土壤中磷(P)、钾(K)、钙(Ca)、镁(Mg)、钠(Na)、铁(Fe)、铜(Cu)、锌(Zn)、锰(Mn)、铝(Al)含量,并对测定结果进行分析。结果:栽培与野生夏枯草土壤及其茎、叶、果穗矿质元素含量存在显著差异;P,Cu含量大小顺序为果穗>叶>茎,Mg,Ca,Zn,Fe,Mn,Al元素以叶含量最高,果穗次之,茎最少,K,Na在茎叶中含量较高,其次为果穗;土壤与果穗中Fe元素含量呈极显著相关,与茎及叶呈显著正相关;土壤与果穗、茎及叶中Zn元素含量呈显著正相关;K元素含量在土壤及茎间亦呈显著正相关;栽培与野生品夏枯草各部位对P吸收有富集作用。结论:夏枯草药材与土壤中多数矿质元素含量无直接相关,主要通过选择性吸收调控药材中矿质元素含量。
Objective: The contents of mineral elements in soil and each organ from cultivated and wild Prunella vulgaris were determined in order to provide a theoretical basis for exploitation and protection of wild resources and GAP study.Method: The contents of mineral elements(P,K,Ca,Mg,Na,Fe,Cu,Zn,Mn,Al) in soil and each organ from cultivated and wild P.vulgaris were determined by ICP-AES,and the results were analyzed by correlation analysis.Result: The contents of mineral elements in soil and different organs of P.vulgaris were significant different between cultivated and wild species;the contents of P and Cu ranked in the order of spica>leaf>stem,the order of Mg,Ca,Zn,Fe,Mn,Al from high to low was leaf>spica>stem,the concentrations of K,Na were mainly distributed in leaf and stem,less in spica.A distinctly positive correlation between soil and spica for Fe content,and the relationship between soil and leaf,stem were significant positive correlation,the concentrations of Zn in spica,leaf,stem were positively related to soil,K contents in soil and stem were significant positive correlation.The different organs of cultivated and wild P.vulgaris had a strong tendency to accumulate P.Conclusion: There was no direct relationship between the concentrations of mineral elements in P.vulgaris,and their corresponding soil P.vulgaris adjusts the concentration of mineral elements mainly by active absorption.
