Planting device with water storage function

The invention discloses a planting device with a water storage function. The planting device comprises a tank. An opening is formed in the upper end of the tank, and at least one vertical partition plate is arranged in the tank and is lower than the opening in the upper end of the tank; the tank is divided into at least two spaces by the partition plates, and each space is used as a primary planting chamber or a primary water storage chamber; vertical water partition plates are arranged in the primary planting chambers or the primary water storage chambers, and water seepage chambers are arranged among the water partition plates and the partition plates and are used for being filled with soil; the bottoms of the primary water storage chambers are communicated with the bottoms of the water seepage chambers; cover plates are arranged on the primary water storage chambers. The planting device has the advantages that water can be stored in the primary water storage chambers, at least one plant can be planted in each primary planting chamber, side roots of all the plants can absorb moisture or nutrients from the water seepage chambers, and accordingly the planting device can assist the roots of the plants to meet growth requirements of all the plants; the planting device has the water storage function and can be used in places with shortage of water, and accordingly the purpose of greening drought regions can be achieved.
