摘要
农业节水灌溉应做好的工作:采取工程的、农业的和管理的综合节水措施,降低腾发耗水量,提高农作物水分生产率和灌溉水利用系数;流域和灌区要地表水与地下水联合开发利用,统一管理,改变"近水者先用水"的现状,做到水资源均衡配置,可持续利用;井渠结合,排灌统筹,提高水资源利用率,综合防治旱涝盐碱;实行灌排区自主管理制度,实现可持续发展目标;开展科学研究,明确不同地区节水灌溉的发展方向和技术措施。
Agricultural water saving irrigation work： adopt integrate water saving measures of engineering, agriculture and management to decrease evapotranspiration（ET）, increase agricultural water productivity and irrigation water using coefficient; Combing and utilizing surface water and groundwater, unify management, change the status for ＂nearby water who can use water first＂, realize balance collocation for water resources, sustainability use; Connect well and canal, irrigation and drainage, increase water resources utilization efficiency, integrate prevent drought, water logging, salt and alkali, practice irrigation district self management system, realize sustainability goal; Develop scientific research, definitude water saving develop direction and technology measures in different areas.
