摘　　要：大豆青贮与玉米青贮制作青贮饲料在江苏畜牧业发展中日益受到重视。为探究玉米大豆带状种植中适宜的青贮大豆品种,通过76份大豆材料与玉米科华666以2∶2带状复种混收混合青贮与大豆、玉米单种单收单贮的比较,分析大豆开花期、株高和单位面积大豆青贮产量,选择适宜的大豆品种。结果表明,在复种情况下,对大豆开花期影响较小,受遮阴影响,株高均有不同程度的提高,晚开花类型大豆青贮产量明显提升,青贮总产量增加。综上,青贮大豆和青贮玉米的复种混收混合青贮模式既提高了土地利用率,又提高了青贮产量,具有较好的推广利用前景。The production of silage from soybean and maize is increasingly valued in the development of animal husbandry in Jiangsu Province.To explore the suitable silage soybean varieties for maize and soybean strip intercropping,76 soybean materials were compared with corn Kehua 666 in a ratio of 2∶2 strip intercropping mixed silage with soybean and maize single cropping single storage.The flowering period,plant height,and yield per unit area of soybean silage were analyzed,and suitable soybean varieties were selected.The results showed that under intercropping conditions,the flowering period of soybean had a relatively small impact,and the plant height was increased to varying degrees due to the influence of shading.The silage yield of late flowering soybean significantly increased,and the total silage yield significantly increased.In summary,the mixed cropping and harvesting silage model of silage soybean and silage maize not only improves land use efficiency but also increases silage yield,which has good prospects for promotion and utilization.
