Due to the small population of C. migao , effects of different treatments on cutting propagation were researched to increase and develop the resources by using the cutting of C. migao as the test materials， including different parts of branches (upper, middle and lower), different media (vermiculite, sand, perlite, sand + perlite ) and different types (IBA, ABT-1,GGR-6) and different concentrations of hormone treatments. The results showed that rooting rate in pearlite substrate was 65.56%, which is the optimal matrix. The types and concentration of plant growth regulator had a significant effect on rooting, and the rooting rate could reach 63.33% when the C. migao was soaked in 30 mg/L GGR 6 for 4 h. The rooting effects in descending order were the lower parts, the middle parts and the upper parts of branches.
