Abstract: Potato needs considerable amount of water during its growth.We did experiments on different irrigation methods to compare per Chinese acre water absorption efficiency and economic uutcome.The results showed that production per Chinese acre of dripping irrigation is 61.7% higher than that of spray irrigation and 22.4% higher than that of duct irrigation,Unit area water absorption efficiency and economic outcome:dtipping is 7% and 7% hivhvr than snrav 5% and 22.6% higher than duet.

Key words: Dripping irrigation, Spray irrigation, Ductirrigation, Potato, Productioa, Water absorption efficiency
