农业是国民经济用水大户,同时,农业用水浪费现象十分严重。用先进的灌溉技术改造农业、武装农业,不仅是发展农业生产的大事,也是关系整个国民经济发展的大事。滴灌是现行灌溉技术中省水效果最大、灌水质量最好的一种新兴的灌溉技术。根据试验,滴灌比地面灌溉省水70—80%;比喷灌省水40%节能60%以上。因此,滴灌已引起人们的高度重视,并正在成为灌溉技术发展的方向。一、燕山滴灌技术的诞生和发展1974年,墨西哥政府向我国赠送了滴灌技术和设备。考虑到这些国外引进的设备造价昂贵不易推广,根据国务院领导的指示和水电部下达的任务,水利水
Agriculture is a major source of water for national economy, meanwhile, waste of agricultural water is very serious. To reform agriculture and arming agriculture with advanced irrigation technologies is not only a major event in the development of agricultural production but also a major event that affects the entire national economy. Drip irrigation is an emerging irrigation technology with the highest water saving effect and the best irrigation quality in current irrigation technology. According to the test, drip irrigation saves 70-80% more water than surface irrigation and 40% more energy-saving than sprinkler irrigation by more than 60%. Therefore, drip irrigation has aroused people’s attention, and is becoming the direction of irrigation technology development. First, Yanshan drip irrigation technology was born and developed In 1974, the Mexican government donated to our country drip irrigation technology and equipment. Taking into account the introduction of these expensive foreign equipment is not easy to promote high-quality, according to the instructions of the State Council and the Ministry of MOH issued the task, water conservancy
