However, the underlying mechanisms driving improvements in soil quality and ecological functionality remain insufficiently understood. In this study, we adopted a synergistic remediation approach that integrated multiple switchgrass (<i>Panicum virgatum</i> L.) cultivars with a coal-based soil amendment to enhance saline-alkali land. A field experiment was conducted using five switchgrass varieties (YM-1, YM-2, YM-3, YM-4, and YM-5), each receiving a uniform application of the coal-based soil conditioner at 10 t ha^-1. A traditional control group was not included in this study, as the experimental design focused on direct comparisons between varieties.
