若干引进禾本科牧草的适应性及其评价

The Adaptation and Evaluation of Introduced Perennial Grasses in Xinjiang Aletai Region

2003～2005年在新疆阿勒泰地区草原站对9种禾本科牧草进行了物候期、产草量和适应性研究。结果表明：无芒雀麦、高冰草、披碱草、老芒麦、细茎冰草、中间冰草、粗穗披碱草在适应性、草产量和质量方面表现较好，适宜在该地区大量推广种植，可以作为人工草地建设或天然草场改良的优质牧草。

The experiment was conducted with random plot method from 2003 to 2005, nine grass varieties were evaluated to assess their phenology period, productivity, and adaptation in Xinjiang Aletai region. The result showed that the adaptation, productivity and their quality of Bromus inermisleyss, Thinopyrum ponticum, Elymus dahuricus Turez, Elymus sibiricus L., Elymus dahuricus Turcz, Thinopyrum intermedium and Etymus nutans Griseb were better and make them suitable for planting in Xinjiang Aletai region. They can be planted as artificial grassland or to improve natural grassland.
