摘　　要：以玉米新品种丹玉485为材料,在辽宁不同生态气候区域选择9个点研究该品种的最适宜种植密度。结果表明:综合产量和抗逆等因素,丹玉485在辽东凤城地区合理种植密度为45 000~52 500株/hm^(2),在海城、辽阳、沈阳、铁岭、彰武和兴城等辽南、辽中、辽北及辽西沿海部分地区适宜密度为60 000株/hm^(2)左右,在义县和凌源等辽西内陆地区适宜60 000~67 500株/hm^(2)高密度种植,为丹玉485生产应用提供合理指导意见。Nine different ecological climate areas in Liaoning province were chose to study the most suitable planting density by maize hybrid Danyu 485. Comprehensive consideration of yield and resistance, the results showed that 45 000~52 500 plants/hm^(2) was the reasonable planting density in Fengcheng area, 60 000 plants/hm^(2) in Haicheng, Liaoyang, Shenyang, Tieling, Zhangwu and Xingcheng area were reasonable planting density, while 60 000~67 500 plants/hm^(2) in Yixian and Lingyuan, it provided reasonable guidance for corn production.
