Rice cultivated in cadmium (Cd)-polluted acidic paddy soil poses important health risks in China. Mitigating Cd accumulation in rice is of crucial importance for food safety and human health. In this study, using Chuangliangyou 669 as the ratoon rice variety, a field experiment was conducted in paddy fields with severe Cd pollution (Cd concentration > 1.0 mg kg−1). The aim was to explore the impacts of different nitrogen (N) fertilizer levels (N1-180 kg hm−2, N2-153 kg hm−2, N3-126 kg hm−2) and planting densities (D1-20 cm × 20 cm, D2-16.7...
