Aerial courtyard sponge cultivation system

The invention discloses an aerial courtyard sponge cultivation system which comprises a waterproof layer at the bottom, a water storage layer above the waterproof layer, a root separation layer above the water storage layer, a plurality of soil matrix layers above the root separation layer, permeation increasing water lifting pieces arranged in the soil matrix layers, and the bottoms of the permeation increasing water lifting pieces communicated with the water storage layer. Rainwater runoff collection and rapid infiltration, bottom water storage and supply, vegetation layer purification and drainage adjustment are integrated, rapid water seepage and drainage in rainy days can be achieved, and water is lifted for plant growth in sunny days; water supply from the bottom is mainly used for water ascending, surface soil hardening caused by water descending due to spray irrigation and drip irrigation can be effectively avoided, the water storage layer is provided with an automatic water supplementing device, long
