Abstract: Trace irrigation and micro irrigation were compared with conventional drip irrigation. Water-saving effect of these new water-saving irrigation equipment was grasped.Suitable technical parameters，such as work pressure，buried depth and water yield were groped.Its comprehensive performance，such as degree of durability，energy saving and energy consumption，was understood.It could provide basic material for water-saving irrigation equipment update and create different water-saving irrigation mode depending on the requirements of crop.It would facilitate promotion of agricultural technology and improvement of related technologies.
