摘要：

通过3年的耕作和秸秆条带还田试验,研究了行间旋耕秸秆还田(T1S1)、行间翻耕秸秆还田(T2S1)、行间旋耕秸秆不还田(T1S2)和行间翻耕秸秆不还田(T2S2)四种耕作措施对土壤团聚体及有机碳分布的影响。结果表明:秸秆还田处理提高了0～40 cm土层团聚体平均重量直径(MWD)、>2 mm和0.25～2 mm大团聚体含量及有机碳贡献率,相应地减少了<0.053 mm黏砂粒含量及其有机碳贡献率,提高了0～40 cm土层总有机碳含量及各粒级团聚体有机碳含量;秸秆还田条件下,旋耕处理0～40 cm土层团聚体MWD和团聚体有机碳贡献率均高于翻耕处理,但各土层总有机碳含量及各粒级团聚体有机碳含量均略低于翻耕处理;行间旋耕秸秆还田显著提高了各土层大团聚体和微团聚体含量、MWD及其有机碳贡献率,与其它处理相比明显改善了土壤结构。
