摘要:
以长期定位施肥的设施土壤为材料, 采用土壤有机碳物理分组方法, 研究了长期定位施肥对团聚体内颗粒有机碳(POM C)含量的影响。结果表明, 有机肥和有机无机肥配施处理下的土壤大团聚体内微团聚体之间的粗POM 和单施无机肥处理的粗POM 平均碳含量要比不施肥高6.97 倍和4.85 倍。施肥对细POM C 浓度的影响没有明显规律。长期施用有机肥料或配施无机肥(除AN 处理外)还提高了大团聚体包裹的微团聚体内(intramM)的和游离微团聚体内的(f ree intra-m)POM C 含量, 而无机肥的施用却导致了intra-mM 和free intra-mPOM C 含量下降22.5 %～ 21 .1 %。
