摘　　要：采用不同基质、不同药剂、不同浓度水平及不同季节对海南粗榧进行扦插生根试验．结果表明，海南粗榧半木栓化枝条可扦插成活；最佳的扦插基质为椰糠；IBA为生根的最好药剂，浓度以1500mg／L最理想；秋季扦插比春季成活率高；侧枝扦插生根率较直生枝高，且发根快．In this Paper, the experimental results of the cuttage and root - growing of Cephalotaxus mannii Hook.f. were reported. It showed that: 1) the half-phellemation branches of Cephatotaxus mannii Hook.f. could survive through cuttage; 2) the best cutting medium was the broken coir;3) the best medicament was IBA and the most suitable density 1500 mg/L for the root-growing; 4) the survival rate of the cutting woods in autumn was higher than that of them in spring; 5) the root-growing rate of the lateral branches was higher than that of the upright branches, and in comparision with the latter, the former grew fast.
