摘　　要：试验以无芒雀麦为对照,对缘毛雀麦9708、9701两个品系在开花期、种子成熟期的牧草产量、茎叶比及营养成分进行了比较,结果表明:2个品系的鲜草产量、干草产量均高于对照,9708品系的鲜草产量和干草产量高于9701品系;9708品系的粗蛋白质含量、粗纤维含量低于对照,茎叶比高于对照;9701品系的粗蛋白质含量高于对照,粗纤维含量、茎叶比低于对照;综合分析,2个品系的品质随着生育期的延续逐渐下降,但均优于对照。The ratio of stem to leaf, grass yield and nutrition component of 9701 and 9708 lines of Bromus ciliatus L. cv. Xilinguole at flowering stage, maturing stage and post fruiting vegetative stage were compared, Bromus inermis Leyss cv. Carlton was used as the control. The results showed that： the fresh and dry grass yield of two lines were higher than the control ,the fresh and dry grass yield of 9708 lines were higher than 9701 lines at flowering and maturing stage ;the crude protein （CP）content of 9708 lines was lower than control at flowering and maturing stage and was higher than control at fruiting vegetative stage; crude fat （CF） content of 9708 lines was lower than control ; the ratio of stem to leaf was higher than control at three phonological phases;CP content of 9701 lines was higher than control and CF content, ratio of stem to leaf were lower than control at three phonological phases. The synthetic analyses showed the quality of two lines gradually decreased with growth developing and the grass quality were better than control.
