In order to improve the efficiency of fertilization in paddy fields, an experiment was conducted in the winter paddy fields in Sichuan Province to investigate the effects of different fertilization methods on the yield of ratoon rice and the accumulation of nitrogen, phosphorus, and potassium in aboveground plant parts. Based on previous research results, we developed a high-yield, high-efficiency, and fertilizer saving application technology for hybrid med-season rice-ratoon rice in winter paddy fields. The results showed that, compared with the currently widely promoted high-yield fertilization method of hybrid med-season rice-ratoon rice, the new technology could save fertilizer usage by 3.70-8.70 kg/667 m2, reduce fertilization frequency by 3 times, and save fertilization labor costs of 68.0-75.0 yuan/667 m2. This technology provides technical support for high-yield and efficient fertilization of ratoon rice in winter paddy field areas in Sichuan Province.
