摘　　要：针对毕节地区缺乏高蛋白质饲草的现实,为筛选出适合该区的优质、高产苜蓿品种,对20个苜蓿品种进行了引种试验,并测定不同苜蓿品种的株高、分枝数、产草量等指标.结果表明:所有参试苜蓿品种在生长速度上存在显著差异(P<0.05);休眠期和刈割期株高最高的均为‘四季旺’,分别为5.1cm和69.7cm;春季生长速度最快的是‘四季旺’,日均增长0.90cm;‘德宝’的分枝数最高,为49枝;干草产量最高的是‘四季旺’,为9.34t/hm2.说明‘四季旺’在毕节地区春季生长中综合表现最好,最适宜在毕节地区推广种植.In order to screen out alfalfa varieties of high quality,high yield in Bijie District,introduction experiments of 20 alfalfa varieties were carried out,and related indexs of plant height,branch number and yield were determined.The results showed that all introduced alfalfa varieties had significant differences in the growth rate（P0.05）.Plant height of ＇Siriver＇ was the highest during the period of dormancy and mowing,respectively 5.1 cm and 69.7 cm.The growth of ＇Siriver＇ was the fastest in the spring,which average daily growth reached 0.90 cm.Branch number of ＇Derby＇ was 49 branches and the yield of ＇Siriver＇ was 9.34 t/hm2.It was suggested that ＇Siriver＇ had better performance in Bijie District.
