Abstract: in order to apply microelemen fertilize scientifically t, Increase output of super sweet corn, improve quality of super sweet corn .microelemens nutritive characteristics of super sweet corn were studied by way of investigation and analysis of roots, stems and leaves of the super sweet corn plants at different growth stages .The results showed that the nutrient contents of roots, stems and leaves varied with month, that the nutrient of the leaves was in the order of Fe>Zn>Mn>Cu>B, that the nutrient of the root was in the order of Fe>Zn>Mn>Cu>B , that the nutrient of the stems was in the order of Zn>Fe>Mn>Cu>B ,the contents of Cu , Zn in the stems were remarkable relativitywith total , the contents of Fe in the leaves were remarkable relativitywith total, the contents of Mn in the roots were remarkable relativity with total,the contents of Fe,Mn,Cu,Zn,B cganged with growth stages and different organ.
