摘　　要：2018年在内蒙古农业大学牧草试验地进行了草原3号杂花苜蓿(Medicago varia Martin. cv. Caoyuan No. 3)的大田扦插试验。扦插成活率及生长状况的分析对比结果表明:现蕾期为适宜的扦插时期,选取主枝中段,制成一叶茎枝插穗为最佳的技术条件,扦插成活率及生长状况表现最优,30 d成活率可达76.7%,60 d平均新枝高31.70 cm、平均地上生物量2.40 g。In 2018,the field cutting experiment of Medicago varia Martin. cv. Caoyuan No. 3 was carried out in the forage grass test site of Inner Mongolia Agricultural University in Hohhot. The results indicated that the budding period was a suitable cutting stage,and the best technical condition was to select the middle section of the main branch to make one-leaf stem and branch cuttings. The survival rate and growth status of the cuttings were the best. The 30 d survival rate could reach 76. 7%,the 60 d average new branch height was 31. 70 cm,and the average aboveground biomass was 2. 40 g.
