Abstract This study was focused on optimizing the conditions of soft-wood cutting for Atractylodes macrocephala Koidz., including the concentration and treatment time of IBA and IBA+ NAA and the proportion of turf to perlite in substrates. L9(34) orthogonal design with three factors and three levels were adopted, and the best combination was chosen after formula analysis, variance analysis, and range analysis. The results showed that both the maximum survival rate and rooting rate were 93.33%. Statistic analysis showed that treatment with IBA (200€mg·L−1) + NAA (100 mg·L−1) for 20 s, turf to perlite ratio of 1∶3 would be the most favorable combination for soft-wood cutting of A. macrocephala.
