摘要
非工程节水措施是提高农田水分利用效率的重要措施之一 ,通过对北方地区各三级区非工程节水措施的调查统计 ,分析了保墒节水措施、节水栽培措施、化学调控措施、节水灌溉管理措施和非工程节水综合措施 5大类 15项非工程节水措施的节水机理、效果 。
Non-engineering water-saving strategy is one of the important measures improving agricultural water use efficiency. The mechanisms and effects of five types and fifteen items of water-saving measures, such as soil moisture retaining, cultivation, chemical modulation, management and non-engineering, are analyzed through investigation and statistics of non-engineering strategy of the third-level regions in northern China. The water-saving potentials of the measures are put forward.
