Trace elements in two varieties of spinach cultivated in soil with different levels of added iron were determined. Addition of iron to soil decreased potassium, sodium and magnesium contents in spinach markedly (p < 0.05), while the contents of zinc, manganese and copper in spinach were not significantly altered (p > 0.05). Differential behavior of spinach varieties was found in the zinc, manganese and sodium contents.
测定了在添加不同水平铁的土壤中种植的两个菠菜品种中的微量元素。向土壤中添加铁显著降低了菠菜中的钾、钠和镁含量（p < 0.05），而菠菜中锌、锰和铜的含量没有显著变化（p > 0.05）。在锌、锰和钠含量方面发现了菠菜品种的差异行为。
