摘　　要：在吉林省湿润冷凉区,以12个玉米品种为试验材料,在不同种植区域比较品种产量高低。结果表明,2 750℃.d积温区平地供试品种以良玉11、先玉335、吉单550的产量最高,分别为13 364.0 kg/hm2、13 217.7kg/hm2和12 726.7 kg/hm2,与其他5个供试品种平均产量水平达到极显著水平。2 750℃.d积温区坡地供试品种以良玉11、先玉335的产量最高,分别为9 652.0 kg/hm2、9 565.3 kg/hm2,与其他5个供试品种平均产量水平达到极显著水平。2 600℃.d积温区平地供试品种以吉单27、科泰199的产量最高,分别为11 746.0kg/hm2、11 645.0 kg/hm2,与其他2个供试品种平均产量水平达到极显著水平。试验明确不同种植区域适宜玉米品种,为该区域玉米高产、稳产、优质、高效的栽培技术,提供科学依据。The yield of twelve maize varieties in cold-humid region of Jilin province was compared.The results showed that on flat land under accumulated temperature of 2 750℃the yield of ’Liangyu11’,’Xianyu 335’,’Jidan 550’ was 13 364.0 kg/hm2,13 217.7 kg/hm2 and 12 726.7 kg/hm2 respectively,which was extremely significant higher than that of the other five varieties.On slope land under accumulated temperature of 2 750℃,the yield of ’Liangyu 11’,’Xianyu 335’ was 9 652.0 kg/hm2 and 9 565.3 kg/ hm2 respectively,which was extremely significant higher than that of the other five varieties.On flat land under accumulated temperature of 2 600℃,the yield of ’Jidan 27’,’Ketai 199’ was 11 746.0 kg/hm2 and 11645.0 kg/hm2 respectively,which was extremely significant higher than that of the other two varieties.The suitable varieties for different plant area were screened in the experiment,which provide scientific basis for high yield,stable yield,high quality,efficient cultivation technique of maize in cold-humid region.
