摘　　要：通过试验研究不同生根促进剂及扦插基质对桂花扦插生根率的影响差异;研究了不同时间对桂花扦插生根率的影响差异。结果表明：桂花扦插以ABT-1^#500 mg·kg^-1＋100%红心土生根率最高,平均生根率达90.3%;生根长,平均生根长达11.3 cm;Effects of different rooting accelerators and cutting substrates on rooting rate of Osmanthus fiagrans were studied. Effects of different time on rooting rate were also studied. The results show that the rooting rate of cuttages of Osmanthus fiagrans is the highest by ABT - 1500 mg·kg^-1 ＋ 100% red subsoil and the average rooting rate reaches 90.3% ; the rooting is in long length, and the average rooting reaches 11.3 cm; the rooting rate of cutting in different time was highest from Aug. to June.
