| 英文摘要 | A sustainable strategy for cadmium (Cd)-contaminated farmland was developed using a rape-rice-rice rotation system. This method combines early maturing and high Cd-accumulating rape variety with low Cd-accumulating rice varieties and alkaline Si-rich fertilizer. Field experiments compared different planting patterns: single-season rice (SR), oilseed rape-rice rotation (OR), rice-rice rotation (RR), modified oilseed rape-rice rotation (MOR), and integrated threecrop rotation (MORR). MORR significantly reduced Cd content in rice grains, boost total crop yield, and enhanced soil Cd removal. It achieved a comprehensive evaluation index of 0.99, safe crop production over three seasons, a soil Cd removal rate of 87.338 g/ha/yr, and economic benefits of 34,915 CNY & sdot;ha- 1. Simulations based on the Cd input-output balance showed MORR cleaned soil Cd below standards in 12 years, outperforming the 15 years required by the Sedum alfredii and peanut rotation (SP). MORR minimized health risks from Cd exposure, balancing safe production, soil remediation, and farmer income, offering a viable solution for sustainable use of Cd-contaminated farmland. |
