摘要
通过 2 1个多年生禾草三年的田间观察 ,从越冬性和产草量上衡量 ,上繁草以中华羊茅、垂穗披碱草、多叶老芒麦、紫野麦草较好 ;下繁草以西北羊茅、毛稃羊茅、冷地早熟禾、紫羊茅 (同德 )、星星草为好。但多叶老芒麦、紫野麦草种子成熟差 ,只能低海拔区 (如同德 )繁殖种源调进。
The comparative test of twenty one species of perennial grass introduced into alpine cold pasture showed that in herbage yield and winter hardiness.Festuca sinensis Keng.Elymus nutans Griseb,Elymus sibiricus L.,Hordeum violaceum Boiss.et were better in top grass,Festuca ry loviana Rererd,Festuca kirilovii Steud,Poa crymophila Keng,Festuca rubra L.and Puccineuia tenuflora Seribn et in bottom grass were better.But Elymus nutans Griseb,Hordeum violaceum Boiss, were not good in ripeness of seeds,therefore,they could be planted an produced seeds in low altitude place. \ \
