Phytoremediation is an essential technique for mines' ecological restoration. Modifiers addition can alleviate the stress of heavy metals to plants and enhanced remediation efficiency. Herein, spent mushroom compost (SMC) and calcium carbonate (CaCO(3)) were added to lead-zinc mine tailings to reveal the mechanism of Macleaya cordata adaptive to heavy metals stress. Pot experiments were conducted in 100% tailing (T), 90% tailing+5% SMC+5% CaCO(3) (T+), and 100% natural soil (NS). The results indicate that SMC and CaCO(3) amendments could improve the structure and fertility of tailings, and pro...
