摘要： Manganese (Mn2 +) fertilization can competitively inhibit cadmium (Cd) uptake by crops, while the newly formed Mn oxides adsorb bioavailable Cd in the soil, thereby achieving effective remediation of Cd-contaminated soils. However, the potential influence of co-existing nitrate (NO3-) in soils has often been ignored in previous studies. Here, the effects of Mn2+ on wheat Cd accumulation, soil metal fractionation, and microbial community upon NO3- addition were investigated through pot and hydroponic experiments. Counterintuitively, Mn2+ and NO3- addition enhanced Cd accumulation in wheat grains (0.1 %-39.7 %) in a NO3- dosage-dependent manner. NO3- addition weakened the competitive absorption of Mn2+ by lowering soil pH, increasing Cd bioavailability, and promoting the transport of Cd into wheat plants. The competitive advantage of Mn over Cd was further diminished by soil microorganisms, which accelerated Mn2+ oxidation while inhibiting NO3-reduction. Furthermore, higher NO3-levels facilitated co-accumulation of nitrate and cytoplasmic Cd in wheat leaves, which aggravated oxidative stress and further undermined the protective effect of Mn. This study demonstrates that NO3--containing fertilizers weaken the remediation efficiency of Mn-based amendments in Cd-contaminated soils and highlights the need of considering interactions among remediation agents, microbes, and coexisting ions for food safety.
