摘要
合肥市近郊菜园生产的１３种蔬菜中，矿质营养元素含量水平是Ｃａ＞Ｍｇ＞Ｆｅ＞Ｚｎ＞Ｍｎ＞Ｃｕ。营养元素含量变动范围大致为：Ｃａ、Ｍｇ１．０～１０．０ｇ·ｋｇ－１，Ｆｅ７０～２５０μｇ．ｇ－１，Ｍｎ１５～１８０μｇ·ｇ－１，Ｚｎ３０～１２０μｇ·ｇ－１，Ｃｕ１０～３０μｇ·ｇ－１。矿质营养元素含量丰富的蔬菜有苋菜、蕹菜、芹菜、菠菜等。叶茎类蔬菜矿质元素含量高于果菜类蔬菜，不同蔬菜的含量差异达５～７倍甚至２０倍以上，而同种蔬菜不同样品之间含量差异多在１倍以内。
Thirteen kinds of vegetables (contained 117 samples) around Hefei city were investigated.The concentration of mineral nutrients in the vegetables showed Ca>Mg>Fe>Zn>Mn>Cu,which were 1 6～10 0 g kg -1 for Ca and Mg,70～250 μg·g -1 for Fe,15～180 μg·g -1 for Mn,30～120 μg·g -1 for Zn and 10～30 μg·g -1 for Cu.The content of leaf and stem vegetable species is higher than that of fruit vegetable species.The mineral concentration varied greatly (5～7 times) among different vegetable species while had little change between individule plant of the same species.
