江淮地区常年稻-麦轮作面积4,500多万亩、占全国的2/3,年产粮4,000万吨以上,长期以来为保障国家口粮安全作出了重要贡献.然而江淮稻、麦传统生产中普遍存在资源利用不充分,季节间分配不合理,灾害频发;周年秸秆机械化还田耕作、播种质量差,生产肥水药投入大等问题,造成丰产增效抗逆难以兼顾,特别是小麦产量低、品质差,诱发冬季弃耕,直接威胁区域粮食生产和农民增收,甚至影响国家口粮安全生产.在国家重点研发计划“粮食丰产增效科技创新”重点专项的支持下,安徽省农业科学院稻麦创新团队结合安徽粮食多元种植制度与特点,针对江淮不同区域不同种植制度下粮食周年丰产增效技术要求,在淮北-沿淮、江淮中部、沿江-江南三大粮食主产区,开展了主要粮食作物周年丰产增效技术模式创新、优化集成与示范应用,创建了江淮稻-麦周年丰产高效抗逆栽培技术模式并成功应用.
