Integrated rice farming combines rice planting with aquaculture or livestock farming to form a benign cycle of farmland ecosystems. This study systematically analyzes the regulatory effects of typical models such as rice-duck, rice-fish, and rice-crab on paddy soil organic matter, nitrogen, phosphorus, and potassium nutrients, and trace elements, explores key mechanisms such as animal manure return to the field, water disturbance, and microbial activity, and verifies the actual effects of integrated farming in improving acidic soil and enhancing fertility stability through practical cases such as Deqing Xingqing Family Farm. At the same time, its green agricultural value is evaluated from the perspectives of reducing weight and pollution, efficient nutrient utilization, and ecosystem services. Studies have shown that integrated rice farming plays a positive role in promoting the dynamic optimization of soil nutrients and improving soil health, providing strong support for the sustainable development of agriculture. Finally, this study proposes suggestions such as strengthening mechanism research and policy support, and promoting regional adaptation models, in order to promote the scientific application and large-scale promotion of integrated rice farming models.
