| Abstract: | Xilin Gol League is the main distribution area of the typical grassland in China,and is also an im- portant production base of green animal husbandry products. The paper studied the development status of sown grassland in Xinlin Gol League through the data collection and a field survey of 26 sample plots with 8 forage species and mono and mixed sowing. The highest yield of forage species with mono cultivation was Medicago sa-tiva ,which produced the hay of 4 730 kg/hm^2 in Zhenglan Banner,the highest yield of mixed cultivation was Medicago sativa with Elyrnus sibiricus, the hay is 6 663 kg/hm^2 in southwest of Xiwu Banner. Moreover, the paper presented the policy recommendations and measures for sown grassland development, which is useful for the further scientifically planning of the sown grassland development. |
