摘　　要：以4年生‘奥斯特’北美冬青为试材,研究了不同基质组合、不同促根剂种类和浓度、不同穗条老嫩程度、插穗长度对北美冬青嫩枝扦插繁殖生根的影响。结果表明:不同基质组合、穗条老嫩程度、插穗长度的处理均对北美冬青嫩枝扦插生根有显著影响,其合适处理组合为穗条长3 cm,带1叶的极嫩枝,基部用1 000 mg/L的NAA速蘸2 s,扦插于草炭土∶珍珠岩∶蛭石体积比为3∶5∶2的基质,扦插成苗率最高。With 4 years old Ilex verticillata ‘ Oosterwijk’ as the test material,influences of different matrix composition,types and concentration of rooting regulators,different cutting types,different cutting length on softwood cutting propagation of ‘ Oosterwijk’ had been investigated.The results indicated that different matrix composition,cutting types and cutting length influenced on softwood cutting propagation significantly.Softwood of 4 years old,3 cm long,with one leaf should be taken as propagator for regenerating Ⅰ.verticillata.The base of cuttings should be treated with 1 000 mg/L NAA rooting regulator in 2 seconds,then the cuttings should be put in the matrix with peat soil∶ perlite∶ vermiculite （volume rate） =3∶ 5∶ 2.This treatment led to high cutting survival rate.
