| 摘 要： | 研究旨在明确稻麦轮作下秸秆还田对土壤基础养分的影响。以稻麦轮作系统为研究对象,采用Meta分析方法定量研究了土壤基础养分对秸秆还田的响应及其影响因素。结果表明,短期内(<2年)秸秆还田能够显著提升土壤有机碳和活性有机碳的含量,其中活性有机碳对秸秆还田的响应程度要高于总有机碳。低秸秆还田量(RS <3750 kg hm^-2和WS <3000 kg hm^-2)对土壤基础养分的提升效果不显著,而全量秸秆还田(RS 3000~6000 kg hm^-2和WS 3750~7000 kg hm^-2)能够显著提升土壤速效磷、有机碳和活性有机碳的含量。对于不同耕作措施而言,旋耕或翻耕措施均可以显著提升土壤有机碳的含量;此外,旋耕显著提高全氮和活性有机碳的含量,翻耕显著提高土壤速效磷和速效钾的含量。稻麦轮作下秸秆全量还田配合旋耕或者翻耕措施能够增加土壤基础养分含量,达到土壤地力培育的效果。
