摘要
西方牧冰草５个品种和羊草在内蒙古西部地区旱作条件下的建植水平均受播种当年降水条件的影响。干旱年份播种，幼苗存活率低，建植水平差。降水量接近或高于平年年份播种，西方牧冰草和羊草均可获得较好的建植效果，其中西方牧冰草品种Ｒｏｓａｎａ和Ａｒｒｉｂａ显著优于当地羊草。
The successful establishment of Pascopyrum smithii and Leymus chinensis depend on the precipitation of the seeding year in the arid and semi-arid areas of Inner Mongolia. Six entries (five cultivars of Pascopyrum smithii and one native collection of Leymus chinen-sis)Showed low seeding vigors and poor stands when seeded in the drought year at three locations ,but all of them established successfully when seeded in the year received rainfall as normal at Huhhot location , where two cultivars of Pascopyrum smithii,Rosana and Arriba established significantly better than native collection of Leymus chi-nensis.
