摘　　要：为了给塞罕坝林区华北落叶松移植容器育苗提供适宜的基质配比方案,在塞罕坝机械林场第三乡林场苗圃内,以阔叶腐殖土、草炭土、牲畜粪肥、黄土等做基质原材料,对其7种配比的育苗结果进行了筛选。通过多重比较,研究不同配比基质对苗木生长的影响。结果表明:不同基质对华北落叶松移植容器苗的地径存在显著性差异,对苗高、茎根比、鲜重和干重之间的影响差异达极显著水平。在塞罕坝林区培育华北落叶松移植容器苗,基质配比以阔叶腐殖土60%、猪羊厮肥30%、过磷酸钙8%、硫酸亚铁2%为最佳。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.
