摘　　要：微型月季因其小巧的株型,艳丽的花色深受人们的喜爱。本试验将‘花多多’水溶性肥料配制成不同电导率(EC值)的肥水液,通过潮汐灌溉的方式处理微型月季‘红宝石阳台’,并对微型月季进行不同浓度多效唑(PP333)叶面喷施处理,分别测定其各项形态指标、花发育状况和相对叶绿素含量等生理指标。结果表明:EC值=1.5 mS·cm^-1条件下,微型月季的冠幅、分枝数、相对叶绿素含量、花茎粗、花蕾数、花朵数和花径等指标均显著高于其他处理,可作为微型月季生产中的最适EC值;而PP333浓度500 mg·L^-1处理条件下,微型月季的整齐度表现最好,可为微型月季株型调控提供一定依据。Rosa chinensis Minima is popular because its small plant type and bright color.This experiment adopted Hua Duo Duo water-soluble fertilizers with different electrical conductivity(EC values).They were used to treat the'Ruby Terrazza'by tidal irrigation systerm.And PP333 at different concentrations was carried out for the'Ruby Terrazza'.The morphological indexes,flower development status and relative chlorophyll content were determined respectively.The results showed that under the conditions of EC value=1.5 mS·cm-1,the parameters of crown width,branch number,relative chlorophyll content,flower stem diameter,bud number,flower number and flower diameter were significantly higher than those of other treatments.It could be used as the optimal EC value in the production of Rosa chinensis Minima.The uniformity performance was the best after treated by 500 mg·L-1 of PP333,which could provide certain basis for the regulation and control of plant type of Rosa chinensis Minima.
