technical field

The utility model belongs to the technical field of roof greening, in particular to a roof three-dimensional vegetation water storage and planting device.

Background technique

The roof area is about 20% to 25% of the urban area. Within the limited urban space, roof greening can increase the coverage of urban green space, adjust the indoor temperature of the top floor, and improve the living environment. At present, roof greening is mostly realized by paving functional layers such as waterproof layer, root-resistance layer (water-permeable layer), and planting layer from bottom to top. The planting layer is basically paved and filled according to the standard of equal thickness. Different plant species have different plant heights exposed to the ground and root depths buried in the soil. The planting layer of equal thickness does not take into account the differences in soil thickness requirements for the normal growth of different plants: on the one hand, the soil layer is shallow, and the nutrient reserves and underground space are only suitable for shallow-rooted plants, and the supply of soil and fertilizer for the normal growth of deep-rooted plants is insufficient. Furthermore, the constructed vegetation community is monotonous, which is not conducive to the long-term stability and succession of the planting environment, and the landscape is poor; As far as plants are concerned, the excess soil and fertilizer resources will increase the construction cost and bring unnecessary load burden to the building structure.

In addition, with the proposal of the sponge city and the guidance of national policies, collecting natural rainfall and applying it to roof greening will definitely be favored by all walks of life.
