摘　　要：为提高粗叶榕扦插育苗的成活率,开展不同生根促进剂及浓度、扦插基质、穗条基部切口形状及基部径粗对粗叶榕扦插穗条生根效果的影响试验。结果表明:粗叶榕扦插以红壤与珍珠岩1∶1混合为基质,基部径粗为0.9~1.2 mm并用ABT 1号800 mg·kg^-1处理扦插效果最佳,平均生根率达到86.9%、平均生根条数为25.1条,平均生根长度为9.2 cm。In order to improve the cutting survival rate of Ficus hirta Vahl,the experiment was carried out to study the effects of different rooting promoters and concentrations,cutting substrate,base incision shape and base diameter on the rooting effect of cuttings of F.hirta.The results showed that the cutting effect was the best while 50%red soil and 50%perlite,basal diameter of 0.9~1.2 mm and 800 mg·kg^-1 ABT1 were used,with the average rooting rate of 86.9%,the average number of rooting strips of 25.1,and the average rooting length of 9.2 cm.
