| 摘 要： | 根据18 a的长期定位试验, 探讨不同施肥处理对关中（土娄）土土壤有机碳、导水率、体积质量、总孔隙度、田间持水量和团聚体的影响.结果表明,与对照相比,各施肥处理的田间持水量和总孔隙度均有不同程度提高,土壤体积质量均下降,有机肥和化肥的配合施用效果较好;长期配合施用不同有机物与化肥均有利于提高土壤的持水能力;施用有机肥处理比对照饱和导水率显著增加;长期施用不同有机物配施化肥可以改善土壤的团聚结构,秸秆还田对非水稳性团粒结构的形成有良好作用;长期施用化肥则对土壤团聚体稳定性有一定的负面影响.

| Abstract: | Based on 18-year long-term experiment,this article investigated the impacts of different fertilization regimes on soil organic carbon content,hydraulic conductivity,volumic mass,total porosity and soil aggregate on Lou soil in Guanzhong Plain of Shaanxi,China.The fertilization treatments included control without fertilization(CK),a single application of chemical fertilizer(NPK),single organic manure(M),application of organic manure + chemical fertilizer(MNPK) and application of organic straw + chemical fert... |
