摘　　要：2016—2017在陕西关中东部引黄灌区富平县流曲镇藏村试验基地,选择主推和主栽夏玉米品种8个进行适应性筛选试验,并在筛选基础上选择郑单958、浚单20和陕单609 3个品种进行8个密度试验和示范.结果表明:陕单609、浚单20和榆单9号丰产性较好,较对照品种郑单958增产显著,其增产幅度不同年型之间差异显著,2016年增产1.7%~3.1%,2017年增产8.7%~17.6%.综合抗性好,适合关中东部引黄灌区种植.不同密度对产量影响显著.密度不超过90 000株/hm^2时,密度由低到高,产量增加,密度超过90 000株/hm^2时,随密度增加,产量降低.郑单958和陕单609高产的适宜密度为82 500株/hm^2~97 500株/hm^2,浚单20高产适宜密度在82 500株/hm^3~90 000株/hm^2.In 2016-2017,8 main summer maize varieties were selected for adaptive screening in the pilot base of Tibet village,Liuqu town,Fuping county,the Yellow River irrigated area in the eastern district of Guanzhong in Shaanxi province. Three varieties were selected on the basis of screening： Zhengdan 958,Xundan 20 and Shandan 609 for 8 density test and demonstration. The results showed that Shandan 609,Xundan 20 and Yudan 9 had higher yield than that of Zhengdan 958,and the yield of different varieties was significantly different,which increased by 1. 7% - 3. 1% in 2016 and increase of 8. 7% - 17. 6% in 2017. The comprehensive resistance is better,and they are suitable for planting in the Yellow River irrigated area in the eastern district of Guanzhong. Different density has a significant impact on the yield. The yield is increased when the density is less than 90 000 plants/hm2. When the density exceeds90 000 plants/hm2,the yield decreases as the density increase. The suitable density of Zhengdan 958 and Shandan 609 for the purpose of high yield is 82 500 plants/hm2～ 97 500 plants/hm2; while the suitable density of Xundan 20 is 82 500 plants/hm2～ 90 000 plants/hm2.
