摘　　要：采用正交实验设计,研究生长调节剂种类、生长调节剂浓度、处理时间、扦插基质、插穗类型对战骨扦插的影响。结果表明:插穗类型对成活率和扦插苗叶片数有极显著影响,对株高有显著影响;生长调节剂种类对叶片数有显著影响;综合考虑,扦插时应采用以下组合:150mg/L的吲哚乙酸(IAA),处理8h,扦插基质为沙,插穗粗度1.5cm,可取得较好的效果。By orthogonal design,effect of hormone type,hormone concentration,soaking time,matrix type and cutting type on cuttage Premna fulva Craib were studied.The results showed that cuttings type had significant effect on leaf and survival rate,had effect on stem length,hormone type,and had effect on leaf also.Five factors had no evident efect on nummber of root and root length.The treatment of 1.5cm stem treated with 150mg/L IAA for 8h,sand as substrate,was optimum for survival rate of Premna fulva Craib.
