Abstract: The L9 (34) orthogonal design was applied to test the effects of afforestation method, slope position and canopy density with 3 levels for each treatment on the growth of Piper kadsura seedling under forest. The results showed that: afforestation method, slope position and canopy density have significant influence on biomass fresh weight, the total vine length and the number of primary branches; afforestation method has a significant on the main stem base diameter; primary and secondary factors were afforestation method, canopy density and slope position on promoting biomass fresh weight, the total vine length and the number of primary branches; the optimal combination of promoting biomass fresh weight, the total length of vine, the number of primary branches and the main stem base diameter of P. kadsura are light matrix container seedling planting, downslope, canopy density 0.5—0.7.
