摘要：

为选择适于本地区栽培的高产、优质多年生禾本科牧草，于2014年至2015年在同仁县年都乎乡进行不同多年生禾草的引种试验。结果表明，四种多年生禾草都能适应本地区，但相比之下，在平均草层高度和产量方面多叶老芒麦明显高出其它三种牧草，更适宜在该地区大量种植，可以作为人工草地建设和天然草场改良的优良牧草。

Abstract:

In order to select suitable grass species for local cultivation of high yield and high quality forages, an introduction experiment of 4 different perennial grasses from 2014 to 2015 was conductedin Nianduhu township, Tongren County. The results showed that all the four species of perennial grasses could adapt to the local area. The average height of the grass and forage yield of Siberian wildrye (Elymus sibiricus) ‘Leafy’ was significantly higher than the other three species, Elymus nutans，Poa crymophila，and Festuca sinensis. Thus ‘Leafy’ Siberian wildrye is more suitable for a large area of planting in the region, and it can be used as forage grass for both the artificial grassland and natural grassland improvement.

Key words: Perennial forage grasses, Introduction experiment, Forage yield
