摘要
我国水资源先天不足,农田基础设施建设和节水农业技术推广直接影响国家粮食生产格局和产能,系统总结现阶段全国节水农业发展成效和形势挑战,对支撑粮食增产和服务农业强国建设意义重大。近年来,我国节水农业发展成效显著,但随着粮食生产重心向我国北方转移,提升农业用水效率已成为缓解水粮矛盾的主攻方向。文章围绕我国水浇地、旱地和水田,聚焦用水效率和作物单产提升双目标,提出政策建议,以期为节水农业绿色高质量发展提供有力支撑。
China faces the reality of insufficient water resources,thus the construction of farmland infrastructure and the promotion of water-saving agricultural technoly directly afftect the national grain production pattern and capacity.The systematic summary of the current achievements and challenges faced by water-saving agriculture development play an significance role of serving the grain yield increase and building up strength in agriculture.In recent years,the development of water-saving agriculture in China has achieved significant results.However,with the shift of the focus of grain production to the north of China,improving agricultural water use efficiency has become the main direction to alleviate the contradiction between water and grain.This article focuses on the dual goals of water efficiency and crop yield improvement in irrigated land,dry land,and paddy fields in China,and proposes policy suggestions to provide strong support for the green and high-quality development of water-saving agriculture.
