A method is described by which the effect of chelated Fe can be compared with the effect of ionic Fe in nutrient solution cultures over a prolonged period of time. Plants are grown in two solutions in succession: the one containing all nutrient elements except Fe, the other one containing the Fe compound together with Ca(NO(3))(2). In experiments with soybeans (Glycine maxima (L.) Merr.) and with corn (Zea mays L.) it was shown that a 7-day cycle with the ratio of 4 days nutrient solution to 3 days Fe solution resulted in growth and Fe nutrition similar to plants grown with a normal nutrient solution.
本文描述了一种方法，通过该方法可以在较长时间内比较螯合铁与离子铁在营养液培养中的效果。植物先后在两种溶液中生长：一种溶液含有除铁以外的所有营养元素，另一种溶液含有铁化合物以及硝酸钙[Ca(NO₃)₂]。在大豆（Glycine maxima (L.) Merr.）和玉米（Zea mays L.）的实验中表明，以4天营养液与3天铁溶液的比例进行7天循环，其生长和铁营养状况与用正常营养液培养的植物相似。
