[目的]筛选出适宜阿勒泰地区种植的青贮玉米品种。[方法]2013年在阿勒泰地区挑选5个青贮玉米品种,进行田间品比试验,比较各品种生育期、主要农艺性状和产量。[结果]参试玉米品种的生育天数为113~134 d,除新饲玉12号生育天数为134 d、新贵1号生育天数为125 d外,其余3个品种生育天数相差不大;参试玉米品种株高从高到低依次为新饲玉12号、隆牧1号、新贵1号、新青1号、SC704;参试玉米品种产量由高到低依次为新饲玉12号、隆牧1号、新贵1号、新青1号、SC704;新饲玉12号、隆牧1号以及新贵1号产量均在100 500 kg/hm~2以上。[结论]隆牧1号品种适应性较强,产量较高,表现较好,适宜在阿勒泰地区大面积推广。
[Objective] The research aimed to screen silage maize varieties suitable for planting in Altay region. [Method] In 2013, 5 silage maize varieties were selected in the Altay region. The field ratio tests were conducted to compare the growth stages, major agronomic traits and yield of each variety. [Result] The days of reproductive growth of the tested maize varieties ranged from 113 days to 134 days. Except for the days of birth of Xinjiangyu 12 was 134 days and the days of birth of Xingui 1 were 125 days, the days of reproductive development of the other three cultivars were similar. The plant height of maize varieties from high to low were Xinjueyu 12, Longmu 1, Xingui 1, Xinqing 1, SC704. The yield of the tested maize varieties descended from Xinjueyu 12, No. 1, No 1, Xinqing No.1, SC704; the yield of Xinjiaoyu No. 12, Longmu No.1 and No 1 were above 100 500 kg / hm ~ 2. [Conclusion] Longmu 1 had better adaptability, higher yield and good performance, which was suitable for large area popularization in Altay region.
