| 摘 要： | 以本育9号、平安18、丰禾10号、四单19为试验材料,研究了不同氮素用量对春玉米品质的影响。结果表明：春玉米蛋白质含量随着氮素用量的增加而增加,蛋白质含量在不施氮肥与施氮处理间达到极显著差异,施纯氮200kg.hm-2是提高春玉米淀粉含量的最佳施氮量,氮肥不足或过量施氮均降低春玉米淀粉含量。氮素用量对春玉米脂肪的影响因不同品种而异。

| Abstract: | Taking Benyu No.9,Pingan18,Fenghe No.10 and Sidan19 as materials,the effect of nitrogen application on quality of spring maize was studied.The results showed that protein content increased with the increasing of nitrogen application.The difference of protein content between applying nitrogen treatment and no nitrogen treatment was very significant.The optimal nitrogen application to improve starch content of maize was 200 kg·hm-2,higher or lower both could decrease the starch content.The effect of nitrogen application on fat was different because of varieties. |
