摘要:

为探究青海不同地区抱茎獐牙菜及其土壤中矿质元素的相关关系,采用微波消解-电感耦合等离子体质谱法(inductively coupled plasma mass spectrometry,ICP-MS)对青海省内7个不同地区野生抱茎獐牙菜及其土壤中K、Ca、Na、Mg、P、Cu、Zn、Fe、Mn、Co、Ni、V、Cr、Se等14种矿质元素的含量进行测定,并进行相关性分析。结果表明:抱茎獐牙菜及其土壤中矿质元素的含量存在较大的差异。抱茎獐牙菜中有17对矿质元素含量存在显著相关性(P<0.05或P<0.01);抱茎獐牙菜对P具有强的富集作用,富集系数为3.17。抱茎獐牙菜与土壤间共有22对矿质元素存在显著或极显著的相关性,其中抱茎獐牙菜中Na、Se与土壤中的K、Ca、Mg、Cu、Fe、Mn、Ni、V、Se存在相关性,K、P与土壤P呈极显著正相关,V与土壤Cr为显著正相关。说明,青海不同地区抱茎獐牙菜中矿质元素含量与其土壤中矿质元素含量具有一定相关性。

Abstract:

The aim of this study is to explore the correlation of mineral elements between Swertia franchetiana H.Smith and soil in different areas of Qinghai.Fourteen mineral elements in the wild Swertia franchetiana H.Smith and soil in 7 regions in Qinghai Province were detected by ICP-MS,including K,Ca,Na,Mg,P,Cu,Zn,Fe,Mn,Co,Ni,V,Cr,Se.The analysis results show that there is a big difference in the content of mineral elements between Swertia franchetiana and soil.17 pairs of mineral elements in Swertia franchetiana were significantly correlated (P<0.05 or P<0.01),and Swertia franchetiana has a strong enrichment effect on P,with an enrichment coefficient of 3.17.Twenty-two pairs of mineral elements between Swertia franchetiana and soil have significant or very significant correlations;among them,there is a correlation between Na and Se in Swertia franchetiana and K,Ca,Mg,Cu,Fe,Mn,Ni,V,Se in soil,K and P of Swertia franchetiana were significantly positively correlated with soil P,and V of Swertia franchetiana was significantly positively correlated with soil Cr.In conclusion,the mineral element content of Swertia franchetiana and soil in different areas of Qinghai have a certain correlation.
