Abstract: To elucidate law of nutrient and accumulation changes of super sweet corn, The samples were analyzed in fixed time. The nutrient characters of super sweet corn were studies. The results showed that order of amount of various nutrients in the sweet corn was N>K>P>Ca>S>Mg;. Nutrient contents changed with growth stages and different organ, the contains of N、P、Mg、S in fruit were largest，the contains of Ca in leaf was largest, the contains of K in stem was largest; the contains of P, K, Mg in leaf were consistent relatively with total; the contains of N、Ca in stem were consistent relatively with total; The ratio of N、K、Ca was changed with growth stages; N：P：K：Mg：S=1:0.10:1.41:0.10:0.05:0.06in mature stages.
