摘要: Appropriate field management strategies are essential for improving crop productivity and promoting agricultural sustainability in saline-alkaline soils. To explore the potential of synergistic soil improvement and optimal crop management for agricultural production, this study evaluated crop yield, resource utilization, and soil quality in a field experiment with monoculture spring maize cultivation in a coastal saline soil region from 2015 to 2019. Compared with farmers' practices, improved soil management (gypsum/cattle manure), crop management (variety/density), and a combination of both (ISCM) significantly decreased the sodium content, sodium removal rate, and pH by 51.5-60.2, 9.5-35.2, and 9.9 %, respectively, which increased soil organic carbon and total nitrogen by 31.9 and 22.2 %, respectively. Overall, ISCM was the most prominent in processing. As a result, ISCM increased yield and partial factor productivity of nitrogen by 37.2 and 94.5 %, respectively, and reduced N fertilizer use by 28.6 %. Therefore, soil-crop management, particularly the ISCM strategy, can successfully improve the saline soil environment, increase agricultural productivity, and achieve sustainability under intensive farming practices on saline land.
