Indirect underground trickle irrigation system

The invention relates to an indirect underground trickle irrigation system which comprises a water source and a water transmitting pipe (2), wherein a water outlet (4) is arranged on the water transmitting pipe (2). The indirect underground trickle irrigation system is characterized in that the lower part of the water source is provided with a water nozzle (7) with a control switch (6); the watertransmitting pipe (2) is connected with the water source by the water nozzle (7), and an irrigator (3) is embedded into the soil below the water outlet (4) on the water transmitting pipe (2). The system prevents soil evaporation loss among crops and improves the utilization ratio of water; the water transmitting pipe is positioned above the earth surface, thereby preventing the blockage of a rootsystem; and the invention has simple structure and convenient use, management and maintenance, saves labor, can dissolve fertilizer into water to carry out fertilizer water irrigation and improve theutilization efficiency of fertilizer, is particularly suitable for the viscous soil with worse water permeable ability in a drought and water lacking area and has better effect on an orchard and vegetables of a sunlight green house and a big house.
