摘　　要：采用火焰原子吸收光谱法测定不同品种和不同产地大葱中无机元素K、Ca、Na、Mg、Fe、Mn、Zn、Cu、Cr和Cd。结果表明:不同品种和不同产地大葱中所含无机元素差异较大,这为高营养育种和强化营养栽培提供了重要参考依据。该方法的加标回收率为96.74%—107.20%,相对标准偏差(RSD)在0.44%—2.67%之间,具有良好的准确度和精密度。The amounts of elements K,Ca,Na,Mg,Fe,Mn,Zn,Cu,Cr and Cd in welsh onion of different cultivars and areas were determined by flame atomic absorption spectrometry.There is obvious differences of the inorganic elements in welsh onion of different cultivations and areas,which will provide important bases for breeding of high nutrient and growing of intensive nutrient.The recovery rates obtained by standard addition method are 96.74%—107.20%,and the relative standard deviations are 0.44%—2.67%.The method is accurate and quick.
