摘　　要：为了提高稻田施肥效率,在四川冬水田开展了不同施肥水平对再生稻产量以及地上部植株中氮、磷、钾元素积累影响的试验。基于前期科研成果,我们研发出冬水田杂交中稻-再生稻高产高效节肥技术。结果表明,与目前广泛应用的杂交中稻-再生稻高产施肥技术相比,在保持相近产量水平下,新研发的施肥技术可节省肥料用量3.70~8.70 kg/667 m^(2),减少施肥次数3次,节省施肥人工费68.0~75.0元/667 m^(2)。此技术为四川冬水田区域再生稻高产高效施肥提供了坚实的技术支撑。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 m^(2),reduce fertilization frequency by 3 times,and save fertilization labor costs of 68.0-75.0 yuan/667 m^(2).This technology provides technical support for high-yield and efficient fertilization of ratoon rice in winter paddy field areas in Sichuan Province.
