北京市密云区河南寨镇的小麦种植户发现,通过引进配套时针式喷灌机、半固定喷灌设备等高效灌溉设备,他们终于解决了农田高效节水灌溉的问题。先进设备的投入使用,不仅节省了大量人工,还比漫灌节水3?5成,真正做到了节水增产、节本增效。节水灌溉是指达到节水规范标准的灌溉方式,高于此标准的节水灌溉方式,称为高效节水灌溉。根据灌水器灌溉方式不同和地表是否产生径流,高效节水灌溉分为两大类:一类
Wheat growers in Henan Zhaizhen, Miyun District, Beijing found that they finally solved the problem of efficient water-saving irrigation in farmland by introducing efficient irrigation equipment such as hourglass sprinklers and semi-fixed sprinkler irrigation equipment. Into the use of advanced equipment, not only saved a lot of manpower, but also more than flood irrigation water 3? 5 into, truly save water and increase efficiency of the section. Water-saving irrigation refers to the standard of water-saving irrigation methods, higher than this standard water-saving irrigation methods, known as efficient water-saving irrigation. According to different irrigation methods and whether the ground surface runoff, water-efficient irrigation is divided into two categories: a
