摘　　要：试验设肥料(A)与密度(B)两因素五水平研究了不同施肥水平和种植密度对优良玉米品种双玉919产量的影响。结果表明,肥料和密度对双玉919的产量均有显著影响,且肥料和密度互作效应显著。其最佳栽培模式为追施氮肥337.5 kg/hm2,种植密度6.00万株/hm2,平均单产也最高,达到14 843.20 kg/hm2。The factors of fertilizer（A） and density（B） were designed with five levels in this experiment. The results indicated that fertilizer and density had obvious effects on the agronomic characteristics and yield of Shuangyu 919. When the fertilizer was 337.5 kg N/hm2 and the density was 60 000 plants/hm2,the agronomic characteristics were the best and the yield was the highest（14 843.20 kg/hm2）.
