长期不同施肥处理土壤胶散复合体的研究表明：施用有机肥后，水散性Ｇ０复合体减少，水稳性Ｇ１、Ｇ２复合体增加；Ｇ０、Ｇ１、Ｇ２各复合体的有机碳含量及其松、稳、紧结合态腐殖质含量均有提高。显示有机肥对改善土壤团聚体、稳定土体结构的重要作用。Ｇ０、Ｇ１、Ｇ２三组复合体的有机碳含量和腐殖质结合状态存在差异。
Long-term different fertilization treatment of soil glue complex showed that: after the application of organic fertilizer, water-soluble G0 complex decreased, water-stable G1, G2 complex increased; G0, G1, G2 of the organic carbon content and its Loose, stable, tightly bound humus content increased. Organic fertilizer to improve soil aggregates, soil structure stability plays an important role. The organic carbon content and humus binding state of G0, G1 and G2 complexes differed.
