滴灌也叫滴水灌溉,是近年来在国外发展起来的一种新的机械化,自动化的先进灌水技术。滴灌是将有一定压力的水,通过一系列的管道和滴头,把水一滴一滴的灌入作物根区的土壤中,使土壤经常保持最适于作物生长的湿润状态,从而使作物获得丰收。滴灌技术最早是在四十年代末英国用于温室栽培,到1964年以色列才将滴灌用于沙漠地大面积果园获得成功。以后很快在美国、澳大利亚、墨西哥、意大利、新西兰、突尼斯等十多个国家发展滴灌。到1974年世界滴灌面积已发展到85万亩,大多数都首先使
Drip irrigation, also called drip irrigation, is a new mechanized and automated advanced irrigation technology developed in foreign countries in recent years. Drip irrigation is a process of applying pressured water through a series of pipes and drippers to drip water into the soil in the crop root zone so that the soil will always maintain its optimum moisture content for crop growth, . Drip irrigation was first used in greenhouse cultivation in the late 1940s in Israel. By 1964, Israel successfully used drip irrigation in a large area of orchards in the desert. After the rapid development in the United States, Australia, Mexico, Italy, New Zealand, Tunisia, more than 10 countries such as the development of drip irrigation. By 1974, the world’s drip irrigation area has grown to 850,000 mu, most of which are first made
