【Abstract】 The experimental research was carried out on the campus of Grassland Research Institute, CAAS from 1986～1988. The materials introduced were from Canada, America and China, including three families, 23 genera and 143 species. 84 species came from China and 59 came from abroad. As this research work was finished, there were 106 forages species survived on the experimantal plots. According to the observation, the results obviously showed that the species adapted to meadow grassland were bromegrass (Bromus inermis Leyss Xilingguole), Hybrid bromegrass from Canada, meadow bromegrass from Canada and a rich-leaved Elymus (Elymus sibibrieus L.) from Qinghai Province. Species adapted to typical grassland were wheatgrass (Agropyron cristatum) from USA, Agropyron desertorum from USA and A. cristatum from Canada. Species adapted to uncultivated land of Loess Plateau were Agropyron mongolicum from Animal Science Academy of Inner Mongolia, slender wheatgrass (A. trachycaulum Link) and Russian wildrye (Elymus junceus Fish.) from Canada.更多还原
