对来源于美国、加拿大和中国的4种多年生牧草在宁夏荒漠草原区次生盐碱地的适应性、生产性能和质量进行了比较研究，以筛选适合当地种植的优良牧草。结果表明，披碱草和苇状羊茅的适应性较强，鲜草产量高，分别为577.07 g/m2和391.08 g/m2，极显著高于扁穗冰草和蒙古冰草（P＜0.01），而且品质较好，可作为荒漠草原区次生盐碱地推广种植的优良牧草。扁穗冰草和蒙古冰草在该地区的存活率和产量均较低，需采取保护措施提高苗期存活率，才可在当地大面积种植。
對來源于美國、加拿大和中國的4種多年生牧草在寧夏荒漠草原區次生鹽堿地的適應性、生產性能和質量進行瞭比較研究，以篩選適閤噹地種植的優良牧草。結果錶明，披堿草和葦狀羊茅的適應性較彊，鮮草產量高，分彆為577.07 g/m2和391.08 g/m2，極顯著高于扁穗冰草和矇古冰草（P＜0.01），而且品質較好，可作為荒漠草原區次生鹽堿地推廣種植的優良牧草。扁穗冰草和矇古冰草在該地區的存活率和產量均較低，需採取保護措施提高苗期存活率，纔可在噹地大麵積種植。

Four kinds of perennial grasses from America,Canada and China,comparative studies among their adapt-ability,productive performance and quality in secondary saline-alkali land of desert steppe zone in Ningxia were undertak-en to select fine forages that suitable for local cultivation.The results showed that:Elymus nutans and Festuca arundinacea had stronger adaptability,the yield of fresh grass were 577.07 g/m2 and 391.08 g/m2,which were significantly higher than that of Agropyron cristatum and Agropyron mongolicum Keng (P < 0.01),and they had better quality what made them adapt for planting in secondary saline-alkali land of desert steppe zone.The survival rates and yield of Agropyron cristatum and Agropyron mongolicum Keng were lower in the region,so we should take some measures to improve seedling survival before a large area of planting in the locality.
