There were many defaults in subsurface drip irrigation system from home and abroad, these defaults included such as easy to block up in seeping holes, uneven irrigation effect when mini-pipe space between turn larger, unsuitable to use in high slope fields. Aiming at these problems, the authors in this paper have developed a new subsurface drip irrigation block-up protection and water saving system to overcome these defaults. Results indicated that the infiltrating equipment and seeping head which was made from special technics had good properties in block-up protection, even irrigation effect and significantly water saving effects. This newly subsurface drip irrigation system had advantage in lower water pressure requirement, higher water utilization rate and easy to operation.
