摘　　要：[目的]研究氟节胺、多效唑对常用绿篱植物红叶石楠生长发育的影响,以寻求最优矮化处理方式。[方法]以不同浓度氟节胺以及氟节胺、多效唑复合药剂对红叶石楠进行叶面喷施处理。[方法]25%氟节胺500倍液+400 mg/L多效唑抑制红叶石楠生长的效果最好,其次是25%氟节胺750倍液+400 mg/L多效唑,这2组处理之间差异不显著。除修剪后立即使用25%氟节胺150倍液与300倍液进行喷雾这2组处理之外,其余各组处理与对照差异显著,对红叶石楠均有一定的抑制效果。[结论]综合抑制效果、药剂持续期及用药成本,25%氟节胺500倍液+400 mg/L多效唑复合药剂在绿篱修剪后5 d进行叶面喷施对绿篱红叶石楠的抑制效果最好。[Objective]The aim was to study the effects of flubenzamide and paclobutrazol on growth and development of the hedgerow plant Photinia×fraseri Dress,and explore the best dwarfing methods.[Mothod]Photinia×fraseri Dress was treated with different concentrations of fluorobenzamide and a combination of fluorobenzamide and paclobutrazol by spraying their leaves.[Result]The results showed that 25%fluorbenzamide 500 times solution+400 mg/L paclobutrazol has the best effect on inhibiting the growth of Photinia×fraseri Dress,followed by 25%fluorbenzamide 750 times+400 mg/L paclobutrazol.The difference between the two treatments is not significant.Except for spraying with 25%sulfametamine 150 times solution and 300 times solution immediately after trimming,the treatments of the other groups are significantly different from the control,and they have a certain inhibitory effect on Photinia×fraseri Dress.[Conclusion]Combining the inhibitory effect,the duration of the medicament and the cost of the medication,the 25%flubetamine 500 times solution+400 mg/L paclobutrazol compound medicament was sprayed on the leaf surface 5 days after the hedgerow was trimmed to have the best inhibitory effect on the Photinia×fraseri Dress.
