Effects of Compound Planting of Forage Soybean and Silage Corn on Yield and Quality of Mixed Feed
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 high-yield and high-quality forage crops in this area.
