| 摘 要： | 为了控制青海省的沙化面积,选择新驯化的草种——大颖草,在青海省同德地区与当地品质较好的3种牧草进行品种比较试验,并对这4种牧草(扁穗冰草、同德短芒披碱草、同德贫花鹅观草、大颖草)的生长性能、草产量及牧草营养品质进行了测定。结果表明,同德贫花鹅观草粗脂肪含量最高,粗纤维含量较低,株高最高,鲜草产量最高;扁穗冰草粗蛋白含量最高;大颖草粗脂肪含量居中,粗纤维含量较其他3种牧草高。综上所述,大颖草草产量较高,在沙地能较好地生长,其作为生态治理草种具有较大的实用意义。

Comparative Variety Trial on Roegneria grandiglumis and Other Herbages in Tongde Area of Qinghai Province |
| |
| 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. |
