滴水灌溉技术,简称滴灌。是利用一套低压管道系统(通常使用塑料管)把水或溶于水中的化肥液体一滴一滴地、均匀地而又缓慢地滴入作物根部附近,使作物主要根系活动区的土壤经常保持在适宜于作物生长的最优含水状态的一种先进灌水技术。滴灌的前身是古老的地下灌水技术。随着现代塑料工业的发展,大约在五十年代末,六十年代初,滴灌才形成了一门独立的灌水技术。它既保持了地下灌溉那种浸润作物根层土壤的优点,又具有地面灌溉和喷灌都不能代替的特点,归纳起来滴灌具有如下优
Drip irrigation technology, referred to as drip irrigation. Is to use a low-pressure piping system (usually plastic pipe) to drip water or water-soluble fertilizer liquid drop by drop, uniformly and slowly around the crop roots so that the soil in the main root activity area of the crop is often maintained in a suitable An advanced irrigation technique for optimum watery crop growth. Drip irrigation is the predecessor of the ancient underground irrigation technology. With the development of the modern plastic industry, drip irrigation formed an independent irrigation technology around the late fifties and early sixties. It not only maintains the advantages of subsurface soils infiltrating the root soil, but also has the characteristics of surface irrigation and sprinkling irrigation can not be replaced by the following drip irrigation has the following advantages
