摘要 为评价内蒙古东部区青贮玉米种植的适应性情况,该研究以先玉335作为对照品种,对引进的10个青贮玉米品种进行品种筛选试验。结果表明:丹玉402、北农青贮3740、京科青贮301、东裕120这4个品种的鲜草产量均高于对照品种,但丹玉402、东裕120收获时乳线未形成,且易倒伏、易感病;京科青贮301株高为291.8 cm,且空秆率超过10%,因而不适宜在当地推广。适合在阿荣旗种植的品种为北农青贮3740,该品种熟期适宜,在产量、抗性以及农艺性状等方面均有较好表现,可优先推广。 To evaluate the adaptability of silage corn planting in eastern Inner Mongolia,Xianyu 335 was taken as a control variety,and 10 silage corn varieties were tested in Arun Banner.The results showed that the fresh yields of Danyu 402,Beinong Silage 3740,Jingke silage 301 and Dongyu 120 were all higher than that of the control.However,Danyu 402 and Dongyu 120 did not form a milk line when harvested,and they were prone to lodging.Jingke Silage 301 was 291.8 centimeters high and had a high empty rod rate which exceeded 10%,so it was not suitable for this region.Beinong Silage 3740 has good performance in terms of growth period,yield,resistance and agronomic traits,so it can be promoted preferentially.
