摘　　要：[目的]探讨优良的八角筋扦插技术。[方法]以多年生八角筋枝条为试材,研究以不留叶、留半片叶、留1片叶3种不同叶片处理方式,以及珍珠岩、营养土、泥炭3种不同基质对八角筋扦插成活的影响。[结果]不同叶片处理方式和扦插基质可影响八角筋的生根率、生根数、根长和新叶生长量。留叶量的不同处理方式中以不留叶的处理方式最佳,其生根率为93%,平均根长为67.29 mm;不同栽培基质以泥炭的效果最佳,其生根率达93%,平均根长为95.40 mm。[结论]生产中建议选用泥炭作为基质,采取不留叶扦插,以达到更好的扦插效果。[Objective]To explore the excellent cutting technology of Acanthus montanus.[Method]The effects of three different treatments on cutting survival of Acanthus montanus cuttings,including leaving no leaves,leaving half a leaf and leaving one leaf,and using perlite,nutritive soil and peat substrates were studied.[Result]The results showed that rooting rate,rooting number,root length and growth of new leaves were significantly affected by different leaf treatments and cutting substrates.The results of cutting experiment showed that the cutting method without leaves was the best,the rooting rate was 93% and the average root length was 67.29 mm.The results of cutting experiments on different substrates showed that peat was the best substrate,the rooting rate was 93% and the average root length was 95.40 mm.[Conclusion]It is recommended to use peat as the substrate in production,and the cutting effect is best without leaving leaves.
