A large planter in Guiping City, China, has successfully implemented a new agricultural model, "high-quality rice + high-quality fish," which has resulted in double harvests and income. The model involves cultivating the latest super rice variety and crucian carp, and has yielded significant results, with an average rice yield of 540.6 kg per mu and crucian carp yield of 102.65 kg per mu. The project has been applauded by academic experts for its ecological efficiency and potential to increase income, and plans are underway to expand the demonstration area and promote the model in other regions.
