Abstract: In order to offer the feasible substrate formula for the transplanted container-raised stocks of Larix principis-rupprechtii in Saihanba forestry centre, seven substrates being made of humus soil, turfy soil, livestock wastes and yellow soil et.al were analyzed. The effects of the different substrate formula to seedling growth were studied by the method of multiple comparisons. The results showed that different substrate, different composition had the remarkable difference on the basal diameter, height, height-diameter ratio, fresh weight and dry weight of Larix principis-rupprechtii seedlings. The optimum substrate formula in Saihanba forestry centre for Larix principis-rupprechtii cultivation is the ratio of 30∶15∶4∶1 for humus:pig and goat wastes: Superphosphate: Ferrous sulfate.
