摘　　要：试验研究3个不同施氮量对11个玉米品种产量的影响。结果表明:桂单0810、兆丰588、桂先365属于高产型品种,在生产中可优先考虑。桂单0810、亚航671耐氮肥,获得高产的最佳施氮量为纯氮345 kg/hm^2;桂先365、桂单1125耐氮肥,获得高产的最佳施氮量有待进一步研究;桂单901、亚航0919、兆丰588对氮肥敏感不耐氮肥,施纯氮138 kg/hm^2最有利于产量的提高;桂单162、亚航670耐肥,稳产性能好;华优168、万川1306不耐氮肥。The test study on the effects of 3 different nitrogen application on yield of 11 maize varieties which were selected and promoted on the production. The results showed that Guidan0810, Zhaofeng588 ,Guixian365 belong to the high yield varieties which are preferred in production .Guidan0810,Yahang671 resistance to nitrogen, the best N application to obtain high yield is 345 kg pure nitrogen/hm2; Guixian365,Guidanl 125 resistance to nitrogen, the best N application to obtain high yield needs further study; Guidan901,Yahang0919 and Zhaofeng588 are sensitive and not resistant to nitrogen, the best N application to obtain high yield is 138 kg pure nitrogen/hm2; Guidan162,Yahang670 resistances fertilizer which have good yield stability; Huayou168, Wanchuan1306 not resistance nitrogen fertilizer.
