Abstract: Through 4 factor 2 horizontal orthogonal test design, the research was conducted on different root growth promoters (A), different densities (B) differentvegetal periods (C) and cuttings with different diameters (D) and the influenceon cutting root growth (E). The result indicated that root growth promoter touse ABT-1# (A1) + the density to use 600mg/kg (B2) + cutting growth period with 12 months (C2) + cutting diameters with 1.0~1.3cm (D1), namely A1B2C2D1 combination is best. The high cutting growth rate is achieved, reaching 86.7%. The comparative test of the container cuttings with 8 different types oflight media shows that the proportion of pent soil, sawdust, bark and red subsoie is 3∶3∶3∶1(E0) which proves to be the best. Cutting root growth rate ishigh with large numbers of roots.

Key words: Dalbergia odorifera Chen, net container with light media, cuttage, root growth rate
