通过田间灌水试验和调查资料的分析表明,河西走廊大部分山水灌区水量浪费最多的环节在田间,田间水量浪费最多的地块是条田,因此灌区水资源利用的潜力重点也在田间。挖掘这种潜力:1.要搞好田间工程配套,即渠系、建筑物、田间渠、沟、畦、埂、条田平整配套,为块灌改畦灌创造基础条件。2.采取比较合理的田间工程布置形式。实行畦灌。文中推荐了五种条田田间工程的布置方案。3.在灌区管理、水量调配,节水技术政策等方面采取综合措施,建立全面的节水灌溉体系。
Through field irrigation experiments and survey data analysis shows that most of the Hexi Corridor water irrigation most of the links in the field, the most wasteful fields of land is a strip of land, the irrigated area of ?? the potential of water resources are also the focus of the field. To tap this potential: 1. To improve the supporting field projects, that is, the canal system, buildings, field drainage, ditch, 畦, 埂, field formation supporting facilities for irrigation and irrigation to create the basic conditions. 2. To take a more reasonable form of field engineering layout. Implementation of irrigation. The article recommended five fields of field layout of the project. 3. Take integrated measures in the aspects of irrigation area management, water allocation and water saving technologies and policies, and establish a comprehensive water-saving irrigation system.
