摘　　要：试验旨在筛选出适宜双城地区种植的青贮玉米品种。试验对17个玉米品种的生育期、农艺性状、产量和营养品质进行比较,采用灰色关联分析法对不同品种青贮玉米的综合表现进行量化评价。结果显示,17个玉米品种中青贮奥邦m99株高和茎粗较优,分别为354.9 cm、2.58 cm;天育108绿叶占比为88.57%,与金刚29、大奥7000、m9898、先玉1483、天农九、垦沃9905、金岭青贮418、翔玉998、铁源24无显著差异(P>0.05),显著高于其他7个品种(P<0.05)。鲜草产量在60 t/hm^(2)以上,干物质产量超过20 t/hm^(2)的品种有铁源24、金博士825、先玉1483、天农九、m9898、金刚29。除青贮金谷玉2124和青贮奥邦m99外,其他15个品种的淀粉含量均大于28.00%DM,达到国家一级标准,品种间差异不显著(P>0.05)。金博士825的中性洗涤纤维含量最低,为44.27%DM;天农九酸性洗涤纤维含量最低,为24.07%DM;青贮金谷玉2124的粗蛋白含量最高,为9.32%DM。金博士825、铁源24灰色关联分析的综合评分靠前。研究表明,金博士825、铁源24综合生产性能较好,适宜在双城地区作为优质青贮玉米品种推广种植。The purpose of this study was to screen out silage maize varieties suitable for planting in Shuangcheng area.The experiment compared investigating the growth period,agronomic traits,yield,and nutritional quality of 17 silage maize varieties,and their comprehensive performance data were quantitatively evaluated using grey correlation analysis.The results showed that among the 17 maize varieties,the silage Aobang m99 had the best plant height and stem diameter,which were 354.9 cm and 2.58 cm,respectively.The green leaf ratio of Tianyu 108 was 88.57%,which was not significantly different from that of Jingang 29,Daao 7000,m9898,Xianyu 1483,Tiannongjiu,Kenwo 9905,Jinlingqingzhu 418,Xiangyu 998,and Tieyuan 24(P>0.05),but significantly higher than that of the other seven varieties(P<0.05).The silage yield was more than 60 t/hm^(2) and the dry matter yield more than 20 t/hm^(2) were Tieyuan 24,Jinboshi 825,Xianyu 1483,Tiannongjiu,m9898,and Jinggang 29.Except for silage Jinguyu 2124 and silage Aobang m99,the starch content of the other 15 varieties was greater than 28.00%DM,which reached the national first-class standard,and the difference between the varieties was not significant(P>0.05).The neutral detergent fiber content of Jinboshi 825 was the lowest,which was 44.27%DM.The lowest acid detergent fiber was Tiannongjiu(24.07%DM).The variety with the highest whole plant crude protein content was Jinguyu silage 2124(9.32%DM).Jinboshi 825 and Tieyuan 24 had high comprehensive scores in grey correlation analysis.The study indicates that Jinboshi 825 and Tieyuan 24 have good comprehensive production performance and are suitable for promoting and planting as high-quality silage maize varieties in the Shuangcheng area.
