原始语种摘要: Abstract(#br)It is well recognized that soil tillage practice and straw returning treatment redistribute carbon (C) in soil and promote the bacterial biomass and diversity. Yet, to date the relative impact of soil tillage practice and straw returning on C in soil different fractions and bacteria community composition remains to be tested. The objective of this study was to investigate the influence of long-term cultivation practices (no-tillage (NT) and conventional tillage (CT)) and crop straw returning on dissolved organic matter (DOM), aggregate fraction and bacteria community composition in a 12-year-olds rice-rice-rapeseed (RRR) rotation system. The study included four different cultivation methods, i.e. , NT with or without crop straw returning (NT+S and NT-S) and CT with or without...
