The aim of this study was to screen the annual forage crop varieties suitable for the autumn idle land of Hebei Province and Inner Mongolia, widen the channel of forage production and supply, and relieve the forage grass shortage problem of animal husbandry in spring and winter. A total of 9 forage grass varieties belonging to Gramineae, Leguminosae and Cruciferae were selected to carry out comparison experiment by using randomized block design. The results showed that the highest grass production was observed in Bayou No.3, followed by Sigu K4697 and Qingzhu 308. The fresh grass yield and hay grass yield of Bayou No.3 were 57 502.50 kg/hm2 and 20 723.50 kg/hm2, respectively. For Shijiazhuang of Hebei Province, the optimal varieties were Bayou No.3, followed by Sigu K4697 and Qingzhu 308. For Bayinnaoer of Inner Mongolia, the optimal varieties were Bayou No.3 followed by Sigu No.5 and the fodder soybean. In this study, the annual forage crop varieties suitable for autumn idle land in Hebei Province and Inner Mongolia were determined, which provides scientific basis for further study.
