摘要 To select the optimal varieties and planting modes of forage sorghum and Sorghum*Sudan grass in Liupan Mountain dry farming area of Ningxia,a two-factor randomized block design with 5 varieties and 3 planting modes was conducted.The results showed that the plant height of Super Sugar was increased by 22.58%and the stem diameter of Sorghum 3701 was 33.49%higher than that of local sorghum.The leaf number of Sorghum 3701 and Sorghum*Sudan grass CFSH30 were 12.24%and 18.42% higher than that of local sorghum,respectively.The leaf length of Sorghum 3701,CFSH30,Super Sugar and 3901 of Sorghum*Sudan grass were 37.14%、54.29%、35.78%and 24.08% higher than that of local sorghum,respectively.The leaf width of Sorghum 3701 was 17.50%higher than that of local sorghum.The leaf area of Sorghum 3701 and Sorghum*Sudan grass CFSH30 were increased by 58.64%and 23.03%,respectively,compared with local sorghum.The fresh yield of Super Sugar was increased by 54.20%compared with local sorghum.In conclusion,forage Sorghum 3701,Sorghum*Sudan grass CFSH30 and Super Sugar had optimal performance compared with other varieties,which can be considered as the primary varieties for adjusting and optimizing high-quality forage grass in Liupan Mountain dry farming area of Ningxia.The main agronomic characters and production performance of the mulch-covered hole sowing method were better than those of the traditional sowing and drilling.
