NOVELTY - The micro solar powered self-watering ecological floating island comprises a floating body layer, a filter layer, an earth insulation layer, a casing layer, a micro solar powered irrigation system, and plants. The plants are planted in the casing layer. The floating body layer is provided with through holes by a pipeline. A water conveying tube of the micro solar powered irrigation system is connected with the through holes of the floating body layer by the pipeline. The through holes are ventilation holes. The casing layer covers organic humus soil and root of the plant.    USE - The micro solar powered self-watering ecological floating island is useful for removing organic substance, nitrogen and phosphorus in a eutrophic water body.    ADVANTAGE - The micro solar powered self-watering ecological floating island can increase dissolved oxygen concentration in water body, has enhanced self-purification capacity to achieve better water ecological restoration effect, and does not produce second pollution.    DETAILED DESCRIPTION - The micro solar powered self-watering ecological floating island comprises a floating body layer, a filter layer, an earth insulation layer, a casing layer, a micro solar powered irrigation system, and plants. The plants are planted in the casing layer. The floating body layer is provided with through holes by a pipeline. A water conveying tube of the micro solar powered irrigation system is connected with the through holes of the floating body layer by the pipeline. The through holes are ventilation holes. The casing layer covers organic humus soil and root of the plant. The micro solar powered irrigation system comprises a solar energy battery plate, a water pump, a water output tube, and a nozzle. A support frame of the solar energy battery plate is mounted on the floating body layer. The water pump is placed on a bottom of the floating body layer. One end of the water output tube is connected to the water pump, and other end of the water output tube is connected to the nozzle.
