在阿鲁科尔沁旗地区对引进的高秋眠级紫花苜蓿品种WL440、WL525与正常种植低秋眠级苜蓿品种亮苜进行干草产量、主要性状、品质及相对饲喂价值指标比较评价。结果表明，高秋眠级紫花苜蓿品种WL440、WL525年干草产量分别为11 837、11 445 kg/hm2，较对照品种亮苜分别增产18.67%、14.74%。品质达到《苜蓿干草质量分级》二级苜蓿干草及以上标准。在阿旗地区苜蓿品种WL440、WL525当年产量较为理想，可作为当年丰产品种在当地应用。

The hay yield， main characters， quality and relative feeding value of the introduced high fall- dormancy alfalfa cultivars WL440 and WL525 were compared and evaluated with the normal planting low-fall-rank alfalfa cultivars white clover in Ar Horqin Banner Area. The results showed that the hay yields of WL440 and WL525 alfalfa cultivars were 11 837 and 11 445 kg/hm2， respectively， which were 18.67% and 14.74% higher than that of the control cultivar Liangmu. The quality of alfalfa hay reaches the standard of grade 2 and above in Alfalfa hay quality grading. The yield of alfalfa cultivars WL440 and WL525 in Aqi Horqin Banner Area is more ideal， which can be used as high-yielding cultivars in local area.
