Comprehensive Evaluation of Productivity of 13 Forage Oat Varieties in Ordos Aline-alkali Soil
In this study,13 domestic and foreign forage oat varieties were used as materials for the measurements and analysis of production performance and nutritional quality indices,the evaluation of forage value,and the gray correlation system analysis.The results showed that Qinghai 444 being the tallest,Tianyan No.1 had the largest leaf area and stem diameter,Fuyan No.2 had the largest dry weight/fresh weight ratio,Beiler and Mengyan No.1 had the higher yields.Media had the highest EE content,Qinghai 444 had the highest CP content,Kaimo had the highest WSC content,Mengsiyan No.1 had the lowest NDF and ADF content.The RFV value of Mengsiyan No.1 was the largest,and the feeding value of this variety was the highest.Through the gray correlation analysis ranking of the 13 forage oat varieties was Tianyan No.1＞Beiler＞Qinghai 444＞Kaimo＞Media＞Fuyan No.2＞Surui＞Mengyan No.3＞Muwang＞Mengyan No.1＞Beile No.2＞Mengsiyan No.1＞Taiyangshen.
