摘要： Most of the phosphorus (P) input from feed ends up accumulating in the pond water or sediment, ultimately harming the environment. Rice demonstrates remarkable bioremediation potential. However, the mechanisms by which long-term rice impacts the sediment P cycle in aquaculture environments remain unclear. This study investigated the effects of a six-year rice-fish co-culture on sediment resuspension-driven P release, P speciation, and removal efficiency in intensive aquaculture. Our results indicated that the rice-fish co-culture (RF) system enhanced the P utilization efficiency by 128.36% while decreasing P residue in water and sediment by 77.42% and 34.62%, compared to the monoculture (F) system. The RF system reduced labile P pool (H2O-IP, NaHCO3-IP) contents, leading to a 74.89% and 82.20% reduction in sediment resuspension and P release rates, respectively. Concurrently, stable P pool (NaOH-IP, NaOH-OP) contents increased by 14.21% and 52.99%. Microbial mineralization in the 5-10 cm layer was enhanced, with acid phosphatase activity and relative abundance of functional gene phoC increasing by 19.69% and 327.61%. Our results showed that the six-year RF system enhanced sediment P cycling, reducing P release risk and improving P utilization. These findings inform eco-efficient aquaculture optimization, with future research needing isotope tracing and metagenomics to explore microbial roles.
