摘    要:[目的] 通过对天津蓟县山区8个代表区域的土壤以及常用重点药材根际土壤中无机元素[铁、锰、铜、锌、钾、钙、镁、铅、镉(Fe、Mn、Cu、Zn、K、Ca、Mg、Pb、Cd)]的含量测定,分析与评价土壤背景质量,为天津野生中药扩大种植奠定基础。[方法] 电热板湿法消解,火焰原子吸收光谱法测定Fe、Mn、Cu、Zn、K、Ca、Mg的含量,石墨炉原子吸收光谱法测定Pb、Cd的含量。[结果] 8个区域自然土壤样品中大量元素Fe、K、Ca、Mg的含量较多,Cu、Zn、Pb的含量水平相当。重金属元素Cu、Zn、Pb的含量均未超出标准,1个区域中Cd的含量稍有超标,但尚未对生态环境造成影响。药用植物根际土壤无机元素水平与蓟县山区自然土壤相当。[结论] 天津蓟县土壤无机元素含量适中,均达到自然背景水平,土壤整体质量较优。

关 键 词:蓟县土壤  药用植物  无机元素  含量测定

Abstract:[Objective] Analyze and evaluate the soil quality, through the determination of the contents of the inorganic elements (Fe, Mn, Cu, Zn, K, Ca, Mg, Pb, Cd) from eight representive areas in Tianjin Jixian county and rhizosphere soil samples of major frequently-used medical materials. Try to lay the foundation of plantation of Tianjin wild traditional Chinese medicine. [Methods] Contents of Fe, Mn, Cu, Zn, K, Ca, Mg were carried out by flame atomic absorption spectrophotometry. Pb, Cd were carried out by furance atomic absorption spectrophotometry and electric heating wet digestion. [Results] There were many contents among Fe, K, Ca, Mg which were major elements and the contents of Cu, Zn, Pb were the same level, through the determination of eight natural soil samples. The contents of Cd slightly exceeded the standard in one area, but did not impact on the ecological environment and the contents of Cu, Zn, Pb, did not exceed the standard, through the determination of contents of heavy metal elements. The inorganic contents level from the rhizosphere soil samples of medical materials were correspond to the level of natural areas of Jixian. [Conclusion] It is moderate for the contents of soil inorganic elements and reach to the natural level in Tianjin Jixian and the overall soil quality is good.
Keywords:soil of Jixian  medical material  inorganic element  determination of content
