| 摘 要： | 为探讨秸秆和沼肥同步翻埋还田对秸秆腐解的影响规律,在室温条件下,105 d试验周期内,采用网袋法模拟翻埋还田,系统研究添加沼肥和自来水对秸秆腐解的影响,以及添加沼肥后不同土壤类型和不同秸秆长度对秸秆腐解过程各主要参数的影响规律。结果表明,沼肥对秸秆腐解具有显著的促进作用,添加自来水组的秸秆降解率为33.61%,而添加沼肥组的秸秆降解率则达到42.37%;配施沼肥后,秸秆的降解主要集中在前70 d,试验结束时各试验组的秸秆降解率均高于42%,秸秆长度20 mm试验组的秸秆降解率高于10 mm秸秆,试验结束时20 mm试验组的秸秆降解率达到52%;秸秆长度对半纤维素的降解影响较明显,而土壤类型则对纤维素和木质素降解具有较显著的影响。
