摘　　要：试验分析了饲草大豆与青贮玉米复合种植对混合饲料产量和品质的影响。选择贵州省印江县某15个小区进行试验,分别设置饲草大豆与青贮玉米带状复合种植模式、饲草大豆与青贮玉米同行复合种植模式和青贮玉米单独种植模式3个处理组,每个处理5次重复。饲草大豆与青贮玉米复合种植模式的鲜草产量、干草产量均显著高于青贮玉米单作产量(P<0.05);带状复合种植模式的缠绕率显著高于同行复合种植模式(P<0.05);带状复合种植模式的饲草中蛋白质含量、干物质消化率和相对饲用价值显著高于同行复合种植和青贮玉米单作模式(P<0.05)。饲草大豆与青贮玉米复合种植能够显著提高混合饲料的产量和品质,且带状复合种植模式效果最佳,这为该地区高产量、高品质的优质饲用农作物种植,提供了技术支持。To analyze the effects of compound planting of forage soybean and silage corn on the yield and quality of mixed feed.A total of 15 plots in Yinjiang County,Guizhou Province were selected for the experiment,and three treatment groups were set up,namely,strip compound planting mode of forage soybean and silage corn,peer compound planting mode of forage soybean and silage corn,and single planting mode of silage corn.Each treatment group was repeated for five times.The yield of fresh grass and hay in the compound planting mode of forage soybean and silage corn was significantly higher than that of silage corn(P<0.05).The winding rate of strip compound planting mode was significantly higher than that of the peer compound planting mode(P<0.05).The protein content,dry matter digestibility and relative forage value of the strip compound planting mode were significantly higher than those of the peer compound planting mode and silage corn monoculture mode(P<0.05).The compound planting of forage soybean and silage corn could significantly improve the yield and quality of mixed feed,and the strip compound planting mode had the best effect,which provided technical support for planting highyield and high-quality forage crops in this area.
