摘　　要：为提高挪威槭扦插育苗成活率,以挪威槭缤纷秋色当年生嫩枝为插穗,采用L9(34)正交试验设计方法,研究了扦插基质(A)、激素种类(B)、激素浓度(C)、插穗类型(D)4种因素对挪威槭系列品种生根效果的影响。结果表明:4种因素对缤纷秋色扦插综合生根效果的影响表现分别为D>A>B>C。最佳处理组合为A2B1C2D3,即选择下部的枝条作插穗,在浓度为300 mg·L^-1的激素NAA中速蘸10 s,扦插于基质草炭∶珍珠岩1∶1中生根效果最佳。In order to improve the survival rate of Acer platanoides cutting,taking the experiment was conducted with the twigs branches of Acer truncatum×A.platanoides‘Warrenred’as materials.The effects of 4 factors including rooting substrates(A),hormone type(B),hormone concentration(C)and cuttings type(D)on the rooting effect of Acer platanoides series were studied through orthogonal design of L9(34),and the optimal combination of 4 factors was screened.The results showed that,the synthetic effect of 4 factors on rooting process of Acer truncatum×A.platanoides‘Warrenred’was D>A>B>C.Acer truncatum×A.platanoides‘Warrenred’:the optimum treatment was A2B1C2D3,that was,selecting the lower branches as the cuttings,which was quickly dipped in NAA 300 mg·L^-1 for 10 s and planted in peat∶perlite1∶1,the rooting effect was best.
