The irrigation with low pressure pipeline is an effective water saving irrigation technique,with the characteristics of water and energy saving,occupying less land,using less labor,being easily operated and popularized,so it is widely used in plain region of well irrigation districts in China.

The basic condition for agriculture will be changed dramatically with the development of irrigation techniques and then cause the development of tillage system.

The irrigation with low pressure pipeline is an effective water-saving irrigation technique,with the characteristics of water and energy saving,occupied less land and less labors,easy operation and popularization,so it is widely used in plain region of well irrigation districts in China.

This paper expounds the urgency of the water-saving irrigation, and briefly introduces each kind of water-saving techniques (mainly including the spray irrigation, microperfusion irrigation, drip irrigation, ditch permeability-reducing technique, low-pressure water transmission technique, etc.
