A tree-planting system on a roof is provided to store water temporarily and drain water quickly by using volcanic stone and to control moisture in soil by using a soil protection sheet. A tree-planting system on a roof comprises a root protection film(4), a root protection film protection sheet(6), a water draining/storing plate(8), a soil protection sheet(9), a soil layer(10), and an air pipe(28). The air pipe is buried under the soil layer to let water on the surface be drained easily and feed outside air to soil. The water draining/storing plate has a copper layer to prevent roots of plants from growing to a slab(2). The air pipe has a plurality of holes and the soil protection sheet is provided to the inner peripheral surface of the soil protection pipe. The soil protection sheet is a non-woven fabric. |
