Abstract:

Production performance traits of ‘Teifeata’, ‘Siriver’ and ‘Verko’ varieties of alfalfa(Medicago sativa)and Ganzi varieties of Elymus (Elymus dahuricus)in the alpine pastoral areas of northwestern Sichuan were investigated and observed during 2004-2009 in field plots. Alfalfa plant had high yield in the region for 5 consecutive years. The fresh yield and hay yield of alfalfa had significant difference from that of Elymus (P <0.01). Therefore, alfalfa is worth planting in the area.

Key words: Alpine Pastoral Area, Alfalfa, Elymus dahuricus

摘要：

为了探讨紫花苜蓿(Medicago sativa)与披碱草(Elymus dahuricus)在川西北高寒牧区生产性能,采用田间小区试验的方法,对‘特瑞’、 ‘四季绿’、‘威可’3个紫花苜蓿和‘甘孜’披碱草连续6年(2004-2009)进行产草量测定。结果表明:紫花苜蓿在该地区种植产量高,连续5年(当年除外),其鲜草产量和干草产量分别与披碱草年度鲜草、干草产量有极显著差异(P <0.01),因此,值得在本区推广种植紫花苜蓿。
