近年来在北方井灌区发展起来的低压管道输水灌溉工程,能有效地节水节能。针对低压管道灌溉工程中的管材问题,中国农科院农田灌溉研究所研制成功了可用于灌溉排水的双壁波纹塑料管新型管材。
In recent years, the development of low-pressure pipeline irrigation and drainage projects in northern well irrigation areas can effectively save water and energy. Aiming at the pipe problem in low-pressure pipeline irrigation project, the Institute of Farmland Irrigation of Chinese Academy of Agricultural Sciences successfully developed a new type of double-wall corrugated plastic pipe which can be used for irrigation and drainage.
