摘　　要：目的:对染病和健康人参叶中7种营养元素进行测定比较,探讨其变化对减轻、防治病害的意义。方法:将人参叶粉碎后,用凯氏定氮法对氮N进行测定,用紫外分光光度法对磷P进行测定,用空气-乙炔火焰原子吸收光谱法测定钾K、铁Fe、锰Mn、铜Cu、锌Zn。结果:不同发病程度锈腐病人参叶中7种元素有显著的差异(P<0.05),锈腐病发病程度越重,人参叶中铁Fe、锰Mn、铜Cu、锌Zn含量越高,氮N、磷P、钾K的含量降低。Objective： Detrmined 7 nutrients in health and unheahh ginseng leaves, compared the differents of them, discussing the signification of reduce and prevent diseases as while. Methods： Crushed the ginseng leaves, mensurated the content of N by Kjedahl method. Determined phosphorus by UV. Assayed K, Fe, Mn, Cu and Zn by AAS. Results： The differences between ginseng leaves were significant（P 〈 0. 05） . The content of Fe, Mn, Cu and Zn were higher along with serious of the leaves, but N, Pand K were lower.
