Taking Clerodendrum speciosum as test material, using different concentrations of IBA and NAA mixed solution reproduce cutting experiment was conducted on C. speciosum, comparing the result of September and November, in order to screen out the best concentration combination of improving the C. speciosum cuttage seedling. The results showed that when the concentration of NBA was 50 mg稬-1 and that of IBA was 150 mg稬-1 or 200 mg稬-1 mixed, with this method the rate of survival and rooting was the highest (100% in November). The maximum of average root number and average root length were 9.4 and 4.9 times than that of the control. When the concentration of NBA was 50 mg稬-1 and that of IBA was 150 mg稬-1, the root effective indexes was high in both months, the highest number was 6.42. And then we comprehensively evaluated the effects on rooting of each treatment combination of two months respectively by subordinate function analysis. The results showed that 150 mg稬-1 or 200 mg稬-1 IBA and 50 mg稬-1 NAA mixed solution should be used for the cutting propagation of the C. speciosum in order to achieve the best root quality.
