摘　　要：为筛选适宜云南迪庆高寒地区种植的青贮玉米品种,在香格里拉小中甸镇引入曲晨9号、红单10号、京科青贮932、迪卡625等16个青贮玉米品种,通过田间农艺性状比较和青贮品质分析,应用灰色关联度法综合评价各品种的生产性能。结果表明,迪卡625、振兴508、红单10号的株高较高,平均株高达2 m;鲜草产量较高的是红单10号、曲辰9号、迪卡159、青贮玉米5102,产量分别为68.6、60.5、61.7、63.0 t·hm^(-2);粗蛋白含量较高的是京科青贮932,其次是胜玉2号、迪卡667、禾玉36、青贮玉米5102、迪卡625和禾玉9566。综合各项指标得出,在迪庆香格里拉地区综合表现较好的青贮玉米有京科青贮932、青贮玉米5102、迪卡625、迪卡667,这4个玉米品种穗位高为68.4~85.7 cm,粗蛋白含量为6.62%~8.83%,鲜重为50.1~63 t·hm^(-2),且具有很强的抗病虫能力。To screen silage maize varieties suitable for planting in Diqing Alpine region of Yunnan province, 16 maize silage varieties, including Quchen 9, Hongdan 10, Jingkeqingzhu 932 and Dika 625, were introduced into Xiaozhongdian Town of Shangri-La, and the production performance of each variety was comprehensively evaluated by using grey correlation degree method through field agronomic traits comparison and silage quality analysis. The results showed that the plant height of Dika 625, Zhenxing 508 and Hongdan 10 was higher than 2 m on average, and the fresh grass yield of Hongdan 10, Quchen 9, Dika 159 and Qingzhuyumi 5102 were 68.6, 60.5, 61.7 and 63.0 t·hm^(-2), respectively. Jingkeqingzhu 932 had higher crude protein content, followed by Shengyu 2, Dika 667, Heyu 36, Qingzhuyumi 5102, Dika 625 and Heyu 9566. According to the comprehensive indicators, the silage maize varieties with good comprehensive performance in Diqing Shangri-La area included Jingkeqingzhu 932, Qingzhuyumi 5102, Dica 625 and Dica 667, which had ear height of 68.4-85.7 cm and crude protein content of 6.62%-8.83%. The fresh weight was 50.1-63 t·hm^(-2), and it had strong resistance to disease and insect.
