摘要
鉴于我国水资源紧缺的现状，我国十分重视节水灌溉技术的研究和推广，取得了显著成效。当前适合我国推广应用的节水灌溉工程技术有渠道防渗、低压管道输水、喷灌、微灌、田间地面节水灌溉和简易节水灌溉等。我国目前正在大规模发展节水灌溉，应注意：预先作好充分论证，严格掌握标准；与农业增产技术结合，开发多种水资源；选择优质设备；提高管理水平等。
Water saving irrigation means to use precipitation and irrigation water fully,to reduce the water lost in the irrigation process,and to increase the yield and output value.Since China is short of water resources, close attention is paid to the development and research of water saving technology,and remarkable success has been achieved.There are several water saving irrigation technologies adaptable to our country,such as seepage prevention ditch,low pressure pipeline system,sprinkler system,micro irrigation and other simple water saving irrigation methods.Now China is developing water saving irrigation systems in a wide scope,thus,it is necessary to provide proof in advance,execute the standards strictly,combine water saving irrigation techniques with the technology of improving the yield,exploit various kinds of water resources,select equipment and improve management.
