摘　　要：为探明不同基质对大根报春苣苔(Primulina macrorhiza)叶插繁殖的影响,以大根报春苣苔的全叶片为试验材料,采用正交试验设计,研究泥炭、珍珠岩、蛭石、稻壳炭4种基质对叶片扦插成活率、子株数、新叶总数的影响,并筛选出最优组合。结果表明,在试验的9个处理中,扦插基质以泥炭∶珍珠岩∶蛭石∶稻壳炭为4∶2∶2∶1(体积比)为佳。泥炭对成活率、子株数、新叶总数均有显著影响(P<0.05);珍珠岩对成活率、子株数、新叶总数均无显著影响(P>0.05);蛭石仅对新叶总数有显著影响(P<0.05);稻壳炭仅对子株数有显著影响(P<0.05)。正交分析并推理出,以4种成分为扦插基质时,泥炭、珍珠岩、蛭石和稻壳炭的最佳配比为2∶1∶1∶1(体积比)。In order to find out the effects of different matrix components on cutting propagation of Primulina macrorhiza,taking the whole leaves of P.macrorhiza as experimental materials,orthogonal experimental design was conducted to study the effects of four substrates including peat,perlite,vermiculite and rice husk charcoal on leaf cutting survival rate,number of cotyledons and total number of new leaves,and the optimum combination was selected.The results showed that among the nine treatments,the ratio of peat,perlite,vermiculite,rice husk carbon,for 4∶2∶2∶1(volume ratio)was the best cutting medium.Peat had significant effects on survival rate,number of cotyledons and total number of new leaves(P<0.05);Perlite had no significant effects on survival rate,num⁃ber of cotyledons and total number of new leaves(P>0.05);Vermiculite had significant effects on total number of new leaves only(P<0.05);Rice husk charcoal had significant effects on cotyledons only(P<0.05).Orthogonal analysis showed that the best ratio of peat,perlite,vermiculite and rice husk charcoal was 2∶1∶1∶1(volume ratio)when the four components were used as cutting substrate.
