| 摘 要： | 为高寒地区多年生人工草地建设提供适宜的草种和合理的品种组合、提高人工草地的生态适应性,1998年5月～1999年5月在天祝县金强河甘肃农业大学高山草原试验站进行了多年生禾草引种及混播组合筛选试验,结果表明:多叶老芒麦和冰草产草量高、越冬性好,是高寒地区首选的引种材料;混合播种时,各组合都能获得与单播相近或高于单播的产草量,其中无芒雀麦、多叶老芒麦、冰草和紫羊茅产量均高,且茎叶比较小,是该地区首选的高产优质草群组合。

Study on the Ecological Adaptability of Introduced Perennial Grasses and the Selection of Combinations in Alpine Region |
| |
| Abstract: | In order to find the suitable grass species and their optimum cobinations for artificial grassland development in alpine region, this study was conducted at Alpine Grassland Experimental Station of Gansu Agricultural University from May, 1998 to May , 1999 in Jingqianghe. The results show that the Elymus nutans and Agropyron cristatum are the best among the introduced grass species for perennial artificial grassregion due to their high DM yield and overwinter rate. As for the combinations, DM yields of all combinations are close to, or even higher than the single. The combination of Bromus inermis, Elymus nutans, Agropyron cristatum and Festuca rubra is the best, duetoits high DM yield and low stem/leaf ratio. |
