摘　　要：在大田条件下通过正交实验L9(34),研究取穗部位、生长调节剂、生长调节剂浓度、处理时间4个因素对毛梾硬枝扦插的影响。结果表明:生长调节剂的影响极其显著,取穗部位和处理时间的影响显著,处理浓度的影响不显著,各因素的主次效应为生长调节剂>处理时间>取穗部位>处理浓度,在大田条件下该次试验毛梾硬枝扦插最佳组合为:选用枝条中部的插穗,用200mg/L NAA+IBA(1∶1)混合生长调节剂浸泡2h进行试验。Comus wateri hardwood cutting were investigated in field conditions by means of orthogonal test L9 （34 ）, and the effect of the four factors about branches position,plant grow regulators,concentration of plant growth regulator and processing time were studied. The results showed that plant grow regulators had extremely notable effect on rooting index. Branches position and processing time had notable effect on rooting index. However,concentration of plant growth regulator had not remarkable effect on rooting index. The sequence of four factors of effect on rooting index was, plant grow regulators〉processing time〉 branches position〉concentration of plant growth regulator. Plant grow regulators was the main factor on rooting. In this experiment, the best combination of Comus wateri hardwood cutting was using central branch cuttings,soaked two hours in 200 mg/L NAAq-IBA（1 ： 1）.
