摘　　要：[目的]总结紫玉兰嫩枝扦插育苗技术。[方法]研究了生根促进剂浓度、穗条长度和基质对穗条生根的影响。[结果]不同生根促进剂、穗条长度和基质对穗条生根的影响明显，不同生根促进剂浓度和NAA对穗条生根的影响不明显。[结论]用8～10cm长的穗条经1000mg/L ABT1速醮后扦插于1／2蛭石＋1／2珍珠岩的混合基质中生根效果最佳。[ Objective] The purpose was to study the cutting technique of tender branch of Magnolia liliflora. [ Method] The effects of concentrations of rooting reagents, cutting lengths and cutting medium on rooting ability were investigated. [ Result] The rooting reagents, cutting lengths and cutting medium had obvious effect on rooting rate of Magnolia liliflora ,but different concentrations of rooting reagents and NAA had no obvious effect on the rooting rate. [Conclusion] The best combination of factors was as follows：8-10 cm cutting fast treated by ABT1 with 1 000 mg/L and planted in the cutting medium of 1/2 vermiculite and 1/2 perlite.
