摘　　要：为了筛选出能够替代德美亚1号或与其搭配种植的品种,从而避免由于种植品种单一而产生的病害等问题,通过大垄双行栽培技术对8个参试品种综合性状进行了筛选研究。结果表明:德美亚2号的产量是参试品种中唯一一个超过对照德美亚1号的品种,产量为10 056.3kg·hm-2,比对照高3.34%,植株紧凑,抗倒伏,生育期比对照短6d,其它品种产量均未超过对照。In order to screen a maize variety to replace or collocate planting with Demeya 1,and avoid diseases caused by single variety, comprehensive traits of eight varieties by cultivation technique of double rows sowing with big ridge were screened. The results showed that yield of Demeya 2 was 10 056.3 kg·hm^-2 and more than Demeya 1 over 3.34% ,it had compact plant,lodging resistance,and its growth period was shorter than that of Demeya 1 for 6 days. The yield of other varieties was inferior to Demeya 1.
