Abstract
为筛选出适宜在陇东地区种植的青贮玉米品种,试验探究了 13个青贮玉米品种的农艺性状及草产量,以筛选出草产量高、适应性好的青贮玉米品种,从而为青贮玉米在陇东地区的示范推广提供科技支撑.结果表明,参试青贮玉米品种的鲜草产量以大京九26最高,为109.50 t/hm2,且与其他青贮玉米品种差异显著(P<0.05),其次为西蒙青贮707、禾玉9566、金凯711,其鲜草产量分别为103.95 t/hm2、97.20 t/hm2、97.05 t/hm2,禾玉9566和金凯711的鲜草产量差异不显著(P>0.05);干草产量以金凯711最高,为40.80 t/hm2,其次为西蒙青贮707、大京九26、禾玉9566,其干草产量分别为38.70 t/hm2、37.80 t/hm2、34.35 t/hm2,西蒙青贮707和大京九26的干草产量差异不显著(P>0.05).试验表明,13个参试青贮玉米品种中,大京九26和金凯711最适宜在陇东地区推广种植.
