  • 摘要: 本文旨在研究长期不同施肥处理对南方黄泥田团聚体有机碳固持及其组分分配的影响, 为合理培肥及土壤碳库管理提供依据。基于始于1983年的在黄泥田进行的长期定位试验, 选择不施肥(CK)、单施化肥(NPK)、化肥+牛粪(NPKM)与化肥+全量稻秸还田(NPKS) 4个处理, 采集第36年各处理耕层土壤样品并分析各粒级团聚体有机碳固持及其组分变化。结果表明, 黄泥田耕层土壤以大团聚体(>2 mm)和中间团聚体(0.25~2 mm)为主, NPKM与NPKS处理的土壤大团聚体质量比重分别比CK显著增加22.0和15.5个百分点(P<0.05)。与CK相比, NPKM与NPKS处理中大团聚体对有机碳固持贡献率分别提高25.0和19.3个百分点(P<0.05)。施肥处理的大团聚体内轻组有机碳(LF-C)含量较CK显著增加, 其中NPKS处理后大团聚体中LF-C含量较CK增加32.3% (P<0.05)。大团聚体有机碳含量以及该团聚体内的LF-C含量与水稻产量和有机碳投入量都呈极显著正相关(P<0.01)。以上结果表明, 配施牛粪或秸秆还田有利于增加黄泥田大团聚体比例及其有机碳含量, 进而提高有机碳固持贡献率, 尤其是配施牛粪, 而且有机无机肥配施有利于提高大团聚体内轻组有机碳含量与固持贡献, 秸秆还田更为明显, 可为南方黄泥田施肥管理提供依据。
