摘　　要：通过3因素3水平正交试验设计L9(34)研究了不同生根促进剂(R)、不同生根促进剂浓度(T)及插穗不同基部下切口型(Y)对土沉香扦插育苗生根率、生根数的影响差异,研究了不同基质(E)对土沉香扦插育苗的影响差异。结果表明:使用ABT-1#(R1)+750×10-6(T3)+双削面(Y3),即R1T3Y3组合效果最佳,平均成活率达89.1%、平均单株生根数达9.9条;4种不同基质扦插对比试验中以红壤:珍珠岩=1∶1(E4)最佳,平均生根率达到90.3%。Influence differences of different rooting accelerators （R）, different concentrations of rooting accelerators （T） and cutting-surface types of different base of cuttings （Y） on rooting rate ＆ rooting number of Aquilaria sinen- sis were studied through 3-factors 3-levels orthogonal experimental design L9 （34 ）. Influence differences of different substrates on cutting seedlings of Aquilaria sinensis were studied. ResuLt shows that： using combination of ABT-1 # （R1） ＋750 X 10-6 （Ta） ＋ double-cutting-side （Ya）, that is,R1Ta Ys, can reach the optimal result. The average survival rate are 89.1%,and the average per plant rooting being 9.9;the optimal substrate is red soil ： perlite = 1 ： 1 （E4） among four different kinds of substrates ;the average rooting rate reach 90.3%.
