中文摘要	于20002004年，采用小区试验法研究了来源于中国、美国和加拿大的23个禾本科牧草材料在内蒙古高原锡林郭勒盟苏尼特右旗小针茅荒漠草原的适应性、产草量和营养价值。结果表明：内蒙沙芦草、沙生冰草、沙芦草、蒙古冰草新品系、新麦草P2、新麦草P3和错行新麦草的越冬率大于80G，生产性能好，根量大，水平根幅大，垂直入土深，粗蛋白含量高，可作为荒漠草原地区推广种植的优质牧草。
英文摘要	Introduced forage species may be necessary to improve forage production and stabilize the soils of desert steppe.From 2000 　to 2004,23 perennial gramineous forage varieties and materials from the United States,Canada,and China were evaluated by plot experiments with random design on their adaptation,productivity,and forage quality in Stipa klemenzii Roshev.desert steppe in Suniteyou Banner,Xilinguole League,Inner Mongolia Autonomous Region,P.R.China.10 m2 plot was employed with 5 replicates for each variety.The results show that the overwinter survival rates of Agropyron mongolicum Keng cv.’Neimeng’,A.desertorum(Fisch.) Schult.,A.mongolicum Keng (a native species),A.mongomicum Keng.(a new strain),Psathyrostachys juncea(Fisch.) Nevski cv.’swift’,P.juncea(Fisch.) Nevski(P3),and P.juncea(Fisch.) Nevski cv.’Bozoisky’ were above 80%.Those grasses had higher forage yields and higher crude protein contents than others and produced more root biomass that were distributed to a greater depth and spread over a wider horizontal distribution.The adaptability,high productivity,and high quality of those grasses would make them suitable for more extensive use in the desert steppe area.
