PROBLEM TO BE SOLVED: To provide an automatic water-sprinkling system, storing rain water or tap water for planting trees on the roof top, wall surface and roof of a building and effectively utilizing the stored water without wasting. SOLUTION: This automatic water-sprinkling system is provided by installing a water storage chamber 1A in an upper vessel of the water storage tank 1 for storing the rain water or tap water and a detached chamber 1B in a lower vessel of the same, joining an aqueduct 3 with the detached chamber (1B) for introducing water into the detached chamber 1B, joining a water-supplying tube 4 installed with a water-absorbing material 5 absorbing water by a capillary action with the aqueduct 3, and making so that the water in the water storage chamber 1A flows into the detached chamber 1B from an opening part 1b formed at the bottom surface of the water storage chamber 1A by the consequence that the amount of water vaporized from the water absorbing material 5 is introduced from the inside of the detached chamber 1B to the inside of the aqueduct 3 and the inside of the detached chamber 1B becomes a negative pressure by the amount of the introduced water.
