摘要： 为探明超甜玉米各器官中氮、磷、钾、钙、镁、硫等营养元素元素变化规律和累积量情况，采集不同生育期的玉米样品进行分析。研究结果表明，1、甜玉米吸收各种养分的大小顺序为N>K>P>Ca>S>Mg。2、不同器官养分含量有差异，果实含氮、磷、镁、硫为各部位最高值；叶片钙含量最高；茎部钾含量最高。3、叶片磷、钾、镁含量与全株变化较为一致；茎中氮和钙含量与全株较为一致。4、甜玉米氮、钾、钙的比例随生长的不同而变化，成熟时N:P:K:Ca:Mg:S=1:0.11:0.90:0.09:0.05:0.06。

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.
