多年来,民勤县开展了膜下滴灌技术的应用与研究,在石羊河流域重点治理灌区节水改造工程中,共发展大田滴灌22.62万亩,但部分工程项目效益发挥不很理想,降低了人们应用滴灌技术的积极性,增大了滴灌技术的推广难度。造成这种情况的主要原因是农村分散的种植模式不利于滴灌工程系统的使用,人们对应用滴灌技术不习惯、不放心,技术指导不科学,资金缺乏,工程标准不高等。建议民勤县发展和推广使用膜下滴灌技术时,工程规划设计要因地制宜,注重效益,做好滴灌技术的服务和指导工作;统一连片种植高效作物等。
Over the years, Minqin County has carried out the application and research of drip irrigation technology. In the project of water saving improvement in key irrigation areas of Shiyang River Basin, a total of 22.62 million mu of drip irrigation has been developed. However, the efficiency of some projects has not been achieved well and has been reduced The application of drip irrigation technology people’s enthusiasm, increasing the difficulty of popularization of drip irrigation technology. The main reason for this is that the decentralized planting mode in rural areas is not conducive to the use of drip irrigation systems. People are not accustomed to using drip irrigation technology, they are not assured, unscientific technical guidance, lack of funds and poor engineering standards. Proposed to develop and promote the use of drip irrigation technology in Minqin County, project planning and design should be based on local conditions, focus on efficiency, good drip irrigation technology services and guidance; unified contiguous planting of high-performance crops.
