Preliminary Studies on How to Reduce the Effects of Salinity

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