摘　　要：研究了珍珠岩、蛭石、河沙、菜园土、腐殖营养土等不同基质配比、不同生长素调节剂(IBA、IAA、NAA)及其浓度、生长调节剂与多效唑(PP333)混合使用对扶桑插条生根的影响。结果表明:河沙+腐殖营养土等体积混合的基质对生根的效果最好;IBA处理的生根效果较好,其中以IBA 150mg/L处理的生根率最高,为93.67%;IAA的处理中,以低浓度50mg/L的生根率最高,为90.67%;较高浓度NAA的处理平均生根数较多,但生根率较低。用含PP33320mg/L与IAA 50mg/L或与IBA 150mg/L的混合液处理均能提高扶桑插条的生根效果。The effects of perlite, vermiculite, sand, garden soil, humus nutrition soil different substrates, different auxins （IBA,IAA,NAA） and their concentrations,mixture of auxins and padobutrazol（PP333） on the rooting of cuttings of Hibiscus rosa-sinensis L. were studied. The results showed that the equal volume mixture of sand and humic nutrition soil had the best effect on the rooting. IBA was better for the rooting,in which the rooting rate of the treatment with IBA 150 mg/L was the highest and was 93. 67% ; The low concentration of 50 mg/L achieved the highest rooting rate of 90. 67% in treatments with IAA;The average number of roots was bigger in the treatments with higher concentrations of NAA, but the rooting rate was lower. The mixtures containing PP333 20 mg/L with IAA 50 mg/L or with IBA 150 mg/L could enhance the rooting effect of cuttings of Hibiscus rosa-sinensis L..
