Abstract: In order to control the desertification in Qinghai province,a comparative variety trial on Roegneria grandiglumis,a recently domesticated grass species,and three local forage grass species(Agropyron cristatum,Elymus breviaristatus cv.Tongde,Roegneria pauciflora cv.Tongde)exhibiting high quality in Tongde area was conducted.The growth performance,yield and nutritional quality of the four tested grass species were determined.The results showed that the Roegneria pauciflora cv.Tongde had the highest crude fat content,plant height and fresh grass yield and had lower crude fiber content;the highest crude protein content was observed in Agropyron cristatum;the Roegneria grandiglumis had the medium crude fat content and had higher crude fiber content than the other three grass species.The combined data indicate that the Roegneria grandiglumis has higher grass yield and better growth performance in sandy land,and it can be used as a grass species for ecological management.
