为探索川南冬水田水稻增产节支新模式，从利用冬水田季节性休耕自养特性出发，结合当前适用先进技术、生产利用情况和年度循环特点，以轻简高效为目标，研究出水稻开厢免耕节水强化栽培技术体系，取得了每667 m2增收稻谷100 kg、节约生产成本100元的良好效果，为川南地区水稻高效种植提供了实践示范和技术支持。

 In order to explore a simple and efficient rice production model in winter fallow field, ridge-bed, no tillage and water saving cultivation techniques under rice intensification system was developed based on the production status and annual circulation features in southern Sichuan. The results showed that it can increase rice yield of 100 kg and save cost of 100 yuan per 667 m2, and it provided a practical demonstration and technical support for efficient cultivation of rice in southern Sichuan.
