Abstract: 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, number 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.
