Abstract: The surface water of paddy field,river around paddy field and aquatic organisms were detected in the area where rice-duck integrated farming had been implemented widely.The results showed that the EC,COD and T-N of the surface water of paddy field were generally higher than that of water in paddy field with traditional farming.Drainage from paddy field in symbiotic period of rice and ducks easily leads to water pollution.Therefore,water management should be well performed to prevent water pollution in surrounding areas.
