The results showed that under severe saline-alkali conditions, the carbon-to-nitrogen ratio, ammonium nitrogen, and available phosphorus content in <0.25 mm aggregates significantly decreased (P<0.05). Similarly, nitrate nitrogen and ammonium nitrogen content in 1-2 mm aggregates were also significantly lower under high salinity stress (P<0.05). The geometric mean diameter and mean weight diameter of aggregates significantly reduced in severe saline-alkali conditions compared to moderate conditions (P<0.05), while the proportion of 1-2 mm aggregates increased with increasing salinity. Correlation analysis revealed that salinity was significantly negatively correlated with total carbon and total nitrogen across all aggregate sizes (P<0.01), and significantly positively correlated with the carbon-to-nitrogen ratio (P<0.01). Under high saline-alkali conditions, available phosphorus, ammonium nitrogen, nitrate nitrogen, and aggregate stability indicators were all significantly negatively correlated with salt content (P<0.01). In conclusion, the degree of saline-alkali stress significantly influenced the physicochemical properties and structural stability of soil aggregates, with high salinity potentially leading to nutrient loss and structural degradation., authors=CHEN Shi-yang1,2, CHE Ya-juan1,2, LI Jing-jing1,2, authorsList=CHEN Shi-yang, CHE Ya-juan, LI Jing-jing, authorCompany=1 College of Grassland

articleAbstract=为探究黄河三角洲滨海盐碱地不同盐碱梯度下土壤团聚体的理化性质、稳定性及其关系,本研究采用野外采样与室内分析相结合的方法,测定了不同盐碱梯度下土壤团聚体的养分含量、粒径分布及稳定性指标。结果表明:重度盐碱梯度下,<0.25 mm团聚体中碳氮比、铵态氮和速效磷含量显著降低(P<0.05);1~2 mm团聚体中硝态氮和铵态氮含量也显著下降(P<0.05)。团聚体几何平均直径和平均重量直径在重度盐碱条件下显著低于中度盐碱条件(P<0.05),而1~2 mm团聚体比例随盐碱梯度上升而增加。相关分析表明,含盐量与各粒径团聚体全碳、全氮极显著负相关(P<0.01),与碳氮比极显著正相关(P<0.01);高盐碱条件下,速效磷、铵态氮、硝态氮及团聚体稳定性指标均与盐分呈显著负相关(P<0.01)。综上所述,盐碱程度显著影响土壤团聚体的理化特性与结构稳定性,高盐碱条件可能导致团聚体养分流失和结构劣化。, authors=陈施洋1,2, 车亚娟1,2,

To investigate the physicochemical properties and stability of soil aggregates and their relationships under different saline-alkali gradients in the coastal saline-alkali land of the Yellow River Delta, this study combined field sampling with laboratory analysis to determine the nutrient content, particle size distribution, and stability indicators of soil aggregates across varying gradients. The results showed that under severe saline-alkali conditions, the carbon-to-nitrogen ratio, ammonium nitrogen, and available phosphorus content in <0.25 mm aggregates significantly decreased (P<0.05). Similarly, nitrate nitrogen and ammonium nitrogen content in 1-2 mm aggregates were also significantly lower under high salinity stress (P<0.05). The geometric mean diameter and mean weight diameter of aggregates significantly reduced in severe saline-alkali conditions compared to moderate conditions (P<0.05), while the proportion of 1-2 mm aggregates increased with increasing salinity. Correlation analysis revealed that salinity was significantly negatively correlated with total carbon and total nitrogen across all aggregate sizes (P<0.01), and significantly positively correlated with the carbon-to-nitrogen ratio (P<0.01). Under high saline-alkali conditions, available phosphorus, ammonium nitrogen, nitrate nitrogen, and aggregate stability indicators were all significantly negatively correlated with salt content (P<0.01). In conclusion, the degree of saline-alkali stress significantly influenced the physicochemical properties and structural stability of soil aggregates, with high salinity potentially leading to nutrient loss and structural degradation.
