Description

TECHNICAL FIELD

[0001] The utility model relates to a three -dimensional greening technical field, concretely is a kind of inclined roof three -dimensional greening system. BACKGROUND

[0002] City three-dimensional greening is one of important and effective ways to improve city ecological environment and enrich city greening landscape. With the increasing shortage of urban land resources, three-dimensional greening uses the wall surface of building, inclined roof, wall and bridge and other various carriers, which not only greatly improves the appearance of city, but also effectively improves the ecological environment of city. However, the three-dimensional greening technology in China still faces a series of challenges in application and development process.

[0003] The widely used pot group type modular planting mode is suitable for inclined roof and other flat slope greening, but it is not suitable for slope inclined roof and plant wall applications. This is mainly because the fixation and soil properties of pot group have high requirements for the adaptability of inclined slope and vertical surface. In the pot group type three-dimensional greening, the soil carrier usually adopts a non-water permeable box design. The original intention of this design is to meet the specific needs of water permeability of plant layer. However, this non-water permeable design also has significant drawbacks: because the three-dimensional soil cannot effectively penetrate water downward like natural ground soil, it often causes water retention in the soil after rain or irrigation, which causes plant root rot and poor growth. This not only seriously affects the survival rate and growth period of plants, but also increases the maintenance and management cost of three-dimensional greening. Therefore, it is urgent to develop a new type of three-dimensional greening technology that can adapt to the special requirements of inclined slope, inclined roof and vertical greening wall, and solve the plant growth problems caused by improper water management in traditional soil carrier, so as to improve the survival rate of plants, reduce maintenance cost, further promote the application of three-dimensional greening, and realize the coexistence of efficiency and beauty of city greening.
