| 摘 要： | 土壤微生物生物量在土壤生态系统中具有非常重要的作用。大量的试验研究表明 ,土壤微生物生物量是植物营养元素的一个重要的源与库 ,生物量对土壤养分的调控作用 ,已经成为土壤培肥、耕作制度改革和作物栽培实践中的重要理论依据之一。自从Jenkinson提出了测定土壤微生物量的原理和概念以来 ,Jenkinson和 Powlson提出了测定微生物生物量的方法16] ,Van De Werf和 Verstraete提出了土壤微生物生物量可以分为全微生物量和活动微生物量10 ] ,Anderson和 Domsch提出了生物量与生物活性中细菌与真菌的比例为 2 2 /78% 8]。虽然生物量的研…

| Abstract: | 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. |
