Most hyperaccumulator and economic crops do not grow year-round, leading to limited remediation efficiency. Implementing year-round rotation patterns with known and potential hyperaccumulators or economic crops can improve remediation efficiency. This study evaluated the remediation efficiency and agricultural safety of 10 winter crops and 12 summer crops in field-scale trials. Sedum alfredii Hance (SA) and Cichorium intybus L. (CI) exhibited the highest cadmium (Cd) accumulation among winter crops, reducing soil Cd content by 12.1% and 10.4%, respectively. Helianthus annuus Linn. (HA) was the...
