摘　　要：对涪陵榨菜(茎瘤芥)叶、膨大茎、缩短茎的必需大量元素(N,K,Ca,Mg,P,S)、必需微量元素(Fe,Mn,Cu,Zn,B,Mo)、有益元素(Si,Co,Se,Ni,Sr)分布特征进行分析,结果表明:叶、膨大茎、缩短茎对各元素的吸收与富集具有明显的规律性,如叶、膨大茎、缩短茎中大量元素含量次序均表现出K>N>Ca>Mg,微量元素含量次序均为Fe>Mn>B>Cu>Mo,有益元素含量次序均有Si>Co>Se的特征。在榨菜各器官中,膨大茎中最富集的元素有必需大量元素K,N,P,S,必需微量元素Zn,Cu,必需有益元素Ni,Co,叶主要富集的元素有大量元素Ca,Mg,必需微量元素Fe,Mn,Mo,必需有益元素Sr,Se等。Analysis was made of the essential macro-elements (N, K, Ca, Mg, P and S), trace elements (Fe, Mn, Cu, Zn, B and Mo) and beneficial elements (Si, Co, Se, Ni and Sr) in the leaves, tuber and root of Fuling Zacai (Brassica juncea var. tumida). The contents of the elements in all the three organs studied were in the order of K>N>Ca>Mg, Fe>Mn>B>Cu>Mo, and Si>Co>Se. K, N, P and S, Zn and Cu, and Se and Si were more abundant in the tuber than in other organs. Great enrichment of Ca and Mg, Se and Sr, and Mn, Fe and Mo was observed in the leaves.
