摘要
随着全球气候变化和水资源短缺问题日益加剧,提升农业用水效率已成为全球关注的焦点。综述了节水灌溉技术的发展及其应用,包括滴灌、喷灌、微喷灌和膜下滴灌技术,分析了这些技术的原理、优缺点及适用性,通过富平县旱地小麦节水灌溉、上海市高效节水灌溉建设和贺州市龟石灌区的应用案例,进一步验证了节水灌溉技术的显著综合效益,并对未来节水灌溉技术的发展方向进行了展望,强调了智能化灌溉系统和新型材料应用的重要性,以及政策支持和技术推广的必要性。
As global climate change and water resource shortages intensify,improving the efficiency of agricultural water use has become a major global focus.This paper reviewed the development and application of water-saving irrigation technologies,such as drip irrigation,sprinkler irrigation,micro-sprinkler irrigation and subsurface drip irrigation.The principles,advantages,disadvantages and applicability of these technologies were analyzed.Case studies on water-saving irrigation for dryland wheat in Fuping County,high-efficiency water-saving irrigation in Shanghai and the application case of the Guishi irrigation district in Hezhou City further validated the comprehensive benefits of water-saving irrigation technology.Finally,the paper proposed future development directions for water-saving irrigation technologies,emphasizing the importance of intelligent irrigation systems and the application of new materials,and the necessity of policy support and technology promotion.
