•Changes induced by all leaf litter treatments on soil biochemical and bacterial properties are evaluated.•Soil total nitrogen, available NPK, SMBC and SMBN are increased in all leaf litter treatments.•Adding different leaf litter alters the composition of bacterial community.•Adding leaf litter improved the relative abundance of Proteobacterial..•The Bacteroidetes might be helpful to distinguish the impacts of broad and coniferous leaf litter on soil characteristic. Leaf litters play a very significant role in determining soil physicochemical properties and shaping soil microbial communities in forest ecosystems, but their impact on understory wild ginseng soil is unknown. In order to study that, different leaf litters from five tree species ((A) Acer mono. Maxim. var. mono; (B) Pinus densiflora Sieb. et Zucc.; (C) Juglans mandshurica Maxim.; (D) Tilia amurensis Rupr.; (E) Quercus mongolica Fisch. ex Ledeb) were added to Panax ginseng-growing soil. Our results indicated that the physicochemical properties of soil were significantly affected by all the leaf litter treatments. Soil total nitrogen, available NPK, and soil microbial biomass (carbon and nitrogen) significantly (P
