英文摘要	Soil salinization is an important factor contributing to the deterioration of soil environment and low crop yield in arable land. In this study, the effects of five fulvic acid applications (0 (CK), 150 (T1), 300 (T2), 450 (T3), and 600 (T4) kg center dot ha(-1)) on soil physicochemical properties, humus content of each component, and cotton (Xinluzao No. 82) growth were investigated. It was confirmed that fulvic acid improved soil water-stable macroaggregates, moisture distribution, and desalinization. 0-20 cm soil relative desalinization rate was significantly increased by 2-11.75%. The pH value decreased by 0.09-0.21. The soil organic matter content was significantly increased compared to CK (p < 0.05), with 7.5-26.93% increase in organic matter content in 0-20 cm soil layer. Soil humification was increased to different degrees, with the most significant increase in humic carbon content in T3 treatment (p < 0.05). There was a significant increase in leaf area index (LAI), stem diameter, and plant height of cotton (p < 0.05). Cotton yield increased by 3.64-8.36% compared to CK (p < 0.05). Correlation analysis showed that cotton yield was significantly correlated with the soil textures of saline soils. The best improvement was achieved with 450 kg center dot ha(-1) fulvic acid. The results of this study can provide a theoretical basis for the improvement of saline soils in arid zones to enhance crop growth and yield.
