摘　　要：Longterm continuous straw mulch no tillage increased soil total and active microbial biomass and activities.Tillage methods influenced soil bacterial and fungal biomass and activities.Conventional tillage increased soil bacterial biomass,but the shapes and distributions of soil bacteria differed insignificantly for different tillage soils.No tillage increased soil total and active hyphal length and biomass.The bacterial and fungal contributions to respiration differed remarkably for tillage method experimental soils.Conventional tillage surface soil layer concentrated largely fungal component,while no tillage soil had much bacterial activities.It showed that soil microbial activity and is not consistent with biomass and its composition in different tillage method soils.
