| 摘 要： | 依托10 a定位试验研究了秸秆还田对典型砂姜黑土有机矿质复合体中有机质稳定性的影响机制。田间试验设置5个处理:氮磷钾配施下的小麦和玉米秸秆双季还田(WMS+F)、小麦秸秆还田(WS+F)、玉米秸秆还田(MS+F)、非秸秆还田(F)处理,以不施肥模式下的非秸秆还田为对照(CK)。结果显示,铁铝键合态和紧密结合态有机质含量累计占土壤总有机质的88.70%,且三者变化趋势一致,均呈现WS+F≈WMS+F≈MS+FFCK,并与土壤短程有序、有机结合态铁铝氧化物呈显著正相关,但与非晶型铁铝氧化物呈负相关性。秸秆还田显著促进了土壤有机质累积,并受到土壤铁铝键合态有机质的影响,但由于非晶型铁铝氧化物生成速度较慢,限制了土壤有机质的进一步累积。土壤紧密结合态有机质对其全量的贡献明显高于铁铝键合态有机质,相关机制值得进一步研究。
