摘　　要：以当地玉米高产品种先玉1619为试验材料进行田间试验,设计4个硒浓度处理,并以清水为对照(S 0),研究在大喇叭口期叶面喷施亚硒酸钠对玉米籽粒产量、品质及硒含量的影响。结果表明,随着叶面喷施硒浓度增加,玉米产量、籽粒淀粉、粗脂肪和蛋白质含量先升高后降低,以叶面喷施35 g/hm^(2)处理最高,分别较S 0显著提高36%、12%、27%、9%;玉米籽粒硒含量逐渐升高,以叶面喷施45 g/hm^(2)处理最高,较S 0显著提高405%。综合分析玉米产量、品质及玉米籽粒硒含量,叶面喷施硒最佳浓度为35 g/hm^(2),可达到富硒玉米标准,且产量较高。A field experiment was conducted using the local high-yielding maize variety Xianyu1619 as the experimental material,and four selenium concentration treatments were designed,and the water was used as the control(S 0)to study the effects of foliar spraying of sodium selenite on maize grain yield,quality and selenium content in grains at the big flared stage.The results showed that with the increase of foliar spraying selenium concentration,the yield of maize and contents of starch,crude fat and protein in maize grain increased first and then decreased,and the foliar spraying 35 g/hm^(2) treatment was the highest,which significantly increased by 36%,12%,27%and 9%compared with the control,respectively.Selenium content in maize grains increased gradually,and 45 g/hm^(2) treatment was the highest,which was significantly increased by 405%compared with control.Based on the comprehensive analysis of maize yield,quality and selenium content in maize kernels,the optimal concentration of selenium sprayed on the leaf surface was 35 g/hm^(2),which could meet the standard of Se-rich maize and achieve higher yield.
