对峦大杉扦插繁殖的生根及生长能力与插穗类型、激素种类、激素质量分数、插穗长度、采穗部位、穗条年龄、留叶数量和扦插基质等相关因素进行研究。结果表明：①插穗扦插后84 d产生不定根。峦大杉为皮部生根类型的树种。②采用1年生已木质化的不具顶芽的1级侧枝为插穗，在100 mg*kg－1的ABT生根粉中浸泡4 h，插穗长度12 cm，扦插前去掉下半部2／3针叶，黄心土为扦插基质的扦插繁殖技术，有利于插穗的生根及生长，是扦插繁殖峦大杉的最优组合。表7参6

The interrelation among the rooting and growth ability of Cunninghamia konishii and the type of cuttings，the types and concentration of root growth helping matters，cutting length，cutting place，cutting foliage，and cutting medium were studied．The results showed that cuttings，belonging to bark rooting tree species，sprouted roots at 84 d after cuttage．The following cuttage measures could promote rooting and growing of cutting woods：1-year lignified first king shoots with 12 cm，pruned away foliage under two third of height of coppice shoots and infused with 100 mg*kg－1 concentration of ABT for 4 h before cuttage，wereplanted on yellow soil．
