Abstract
传统水稻生产消耗大量的淡水资源,过量使用农药化肥带来严重的面源污染.通过梳理节水抗旱稻研究进展及近几年多年多点示范数据,指出节水抗旱稻在高产稻田种植可大幅度减少灌溉用水和化肥及农药施用,降低面源污染;在中低产田表现高产稳产.近几年,节水抗旱稻在“玉米改稻”和“棉改稻”上的成功应用,也为当今农业种植结构调整提供了可行的参考方向.推进节水抗旱稻的选育和开发,将有利于粮食安全、生态安全、生产安全.建立标准的审定体系和完善配套栽培技术是节水抗旱稻今后发展中需重点解决的问题.
Rice production consumed a large amount of water resources,pesticides and fertilizers,caused serious non-point source agricultural pollution.Based on the recent research process of WDR and its multi-years demonstration data across multiple sites,this study illustrated that WDR could greatly reduce the consumption of irrigation water,chemical fertilizer and pesticide which caused non-point source pollution in high-yield paddy field.Meanwhile,it could produce high and stable yield in middle-and low-yield field.In recent years,the successful implementations of "rice replace corn" and "rice replace cotton" on WDR cultivation provided a feasible direction for the adjustment of agricultural planting structure.Propelling breeding and development of WDR will be beneficial for food security,ecological security and production safety.The key problems now to be solved for WDR development were corresponding systematic cultivation techniques and normative certification system.
