Abstract: The experiment of applying infiltrating irrigation system was conducted in a sandy land. At the sametime, the method of furrow irrigation and flood irrigation were used to compare with that of infiltrating irrigation. Through autonomous monitoring and controlling to water dynamics, the results proved that the method of infiltrating irrigation can directly provide water as well as fertilizer to plant roots area, also reduce water evaporation, and then maintain good soil water condition.

Key words: Sandy land, Infiltrating irrigation, Autonomous monitoring and controlling
