以不同方法在甜玉米上施用硒，对子粒中硒及其他营养物质含量、生长发育、生理指标、产量等进行分析。结果表明,施硒可显著提高甜玉米子粒的硒含量，增幅达20%～1880%；蛋白质、脂肪、淀粉、子粒可溶性糖和茎秆含糖量均有增加趋势；各处理的产量构成因素和生物产量没有较大差异；对光合速率有明显的促进作用，叶绿素含量有所增加。说明施硒不仅能改善甜玉米品质，还具有一定的生理作用。

Analysis of the content of selenium and other nutrients in grain, growth, physiological index and yield with selenium by the different methods on the sweet corn were studied in the paper. The results indicated that, selenium could significantly increase the content of selenium in sweet corn grain and the increased range reached 20% - 1880%. The protein, oil, starch, soluble sugar in the grain and the sugar content of cane had the increasing tendency. Yield construction factors and biomass yield under each treatment were not much difference. Selenium had significant effects on the rate of photosynthesis. The chlorophyll content had increased. The result of the treatment of selenium showed that the selenium not only can improve the quality of sweet corn, but also has certain physiological functions.
