摘　　要：红叶石楠秋季扦插育苗试验结果表明,不同基质、不同生根剂浓度及浸泡时间对红叶石楠扦插生根率具有极显著影响。红叶石楠选用混合基质(黄心土∶粗河沙∶草木灰=1∶1∶1),萘乙酸(NAA)生根剂200 mg/kg浓度浸泡2 h的生根率最高,达96.2%,可在生产中推广应用。Cuttage seedling experiment of Photinia serrulata was carried out in autumn. The results showed that different matrices ,different rooting agent concentrations and different soaking times had significant effect on rooting rate of Photinia serrulata cottage. When using mixed matrix （Huangxin soil：coarse sand：plant ash=1：1：1）,with 200 mg/kg naphthaleneacetic acid （NAA）rooting agent soaking for 2 hours, the rooting rate was highest which amounting to 96.2%. It can be applied in production.
