摘要：采用多效唑叶面喷施与根部浇灌2个处理方式,叶面喷施500、1 000、2 000mg/L,共5种处理,研究了多效唑对温室盆花月季‘绯扇生长与开花品质的影响。结果表明:叶面喷施1 000mg/L多效唑时,‘绯扇’花发育天数与生长积温增加,可延迟花蕾显色期、张开期,增加盆花张开期生长天数,延长观赏期;缩短植株节间距与枝长,叶色浓绿,降低株高,花径增大,叶片鲜重增加,提高观赏价值;喷施多效唑能够增加盆花月季叶片的叶绿素含量,提高其光合速率与光能利用率,对改善月季‘绯扇鲜花重与花径等品质有重要影响。
By the method of spraying leaves and root rrigation, total five dfferent concentrations, with leave spraying 500,1 000,2 000 mg/L, and irragation 100,200 mg/L, total five treatments to study the effect of paclohutrazol treatment on growth and flower quality of ＇Feishan＇ potted-rose in greenhouse. The results showed that by apraying leaves with paclobutrazol 1 000 mg/L plant height could be suitably controlled through shortening inernod and stem length, green leaves contemporarilly deepened, fresh leave and flower mass increased and flower diameter expanded, although bud turning color stage and flower blooming stage of＇ Feishan＇ were later than control experiment , in turn,its ornamental days were prolonged. Chlorophyll content and leaf photosynthesis rate increased in ＇Feishan＇ by spraying leaves with paclobutrazol 1 000 mg/L were thought to be important to improve its flower value.
