摘　　要：以13个不同玉米杂交种品种为材料,做低氮处理,以正常施氮为对照,随机区组设计,3次重复。对低氮条件下的穗长、穗粗、轴粗、秃尖、穗行数、行粒数、穗粒数、百粒重、含水量、出籽率等10个农艺性状进行测定,研究结果表明,农大1902、C-344×340/137、威玉1号在低施氮肥条件下也能够获得较高的产量;低氮条件下秃尖、含水量和出籽率是决定玉米杂交种产量的关键因素。13 different maize hybrid varieties were used as materials and treated with low nitrogen,and normal nitrogen application was used as control.The design of random block was performed with 3 replicates.Ten agronomic traits including panicle length,panicle diameter,shaft diameter,bald tip,row number of panicle,row number of grains per panicle,number of grains per panicle,100-grain weight,water content and seed yield were determined under low nitrogen condition.The results showed that Nongda 1902,C-344×340/137 and Weiyu 1 could also obtain higher yield under the condition of low nitrogen application.Bald tip,water content and seed yield were the key factors to determine the yield of maize hybrid under low nitrogen condition.
