With increase in organic matter ( OM) , aggregate stability and ALS increased and clay dispersion decreased markedly, which showed that addition in organic matter to salt-affected soils can improve structural characteristics.

• 随有机质含量的增加,土壤团聚体的稳定性显著增加,黏粒的分散性显著降低,阿特伯格极限显著增加,说明增加有机质含量可以显著改善盐化土壤的结构性能。
