Background

Along with the acceleration of the urbanization process, the urban area is continuously enlarged, the population is rapidly expanded, more and more buildings are built, the land which originally belongs to the plant is occupied, the roof which is lack of the plant is abandoned, and a bald place is desertified, so that the urban space is gradually desertified. A series of activities of human beings, industrial and automobile emission and domestic energy release of residents cause deterioration of ecological environment and serious air pollution, and break through the original ecological balance state, so that the urban heat island effect is formed, and the plants are lost. Therefore, the ecological civilization construction is put into thirteen-five plans in China, namely roof greening is encouraged, the urban heat island effect is slowed down in order to better cope with climate change, and the urban immunity function is improved. People who are environment-friendly realize that the roof greening brings many benefits, can absorb carbon dioxide, emit oxygen, purify air, save energy and reduce consumption, beautify the environment, and our city urgently needs more plants.

At present, the existing roof greening is a thick and flaky structure and comprises a leveling layer, a waterproof layer, a root blocking layer, a drainage part, a water storage layer, a filter layer, a matrix layer, a vegetable layer and other heavy protection guarantees. Moreover, the technical construction period is long and the construction is very complicated. And the purpose of roof greening is to allow more greening to cover the roof, instead of laying thick soil and heavy protection guarantee in a sheet mode for a few plants in the existing roof greening technology, the method is an inverted method, and has the following problems:

(1) cost and maintenance problems for roof greening:

the existing roof greening has higher waterproof safety requirements than the common roof greening, and needs to prevent the penetration of plant roots besides soaking and infiltration, so the quality requirement is high, the natural construction cost is also high, and additional maintenance fees are paid every year.

(2) The bearing problem of roof greening:

the existing roof greening usually adopts a layer of thick soil which is piled in blocks or in whole pieces, and the bearing pressure on the roof is too large.

(3) The uncontrolled root application of roof greening causes waterproofing problems:

the existing roof greening mode cannot effectively control the wild growth of the root system, and uncontrollable things that the root system damages the roof often happen. In case of damage to the building caused by root system, the maintenance is very difficult.

(4) The problem of irrigation of roof greening:

the existing irrigation mode is that water is sprayed on the upper surface and slowly permeates into the upper surface, the surface is wet, the root is wet and not permeable, water is still deficient, the roof is just a place directly irradiated by sunlight, the wet ground surface water is quickly evaporated, the irrigation utilization rate is extremely low, and energy is not saved enough.

(5) The pure investment of roof greening has no profit return mode:

the existing roof greening adopts a planting method of landing to root, is inconvenient to transplant and cannot meet the space requirement of plant growth. Often its growth space is defined by pruning, which is a purely expendable model with investment and no return on profit. There is also a risk of roof damage, resulting in delayed roof greening and insufficient power.

Meanwhile, another mode of the existing roof greening is potted plant planting greening, a planting pot of the greening pot is mostly a simple barrel-shaped container, and a water leakage hole is formed in the bottom of the planting pot. Usually, the water is separately available, and when the water is poured, a pot is needed to be used, which is time-consuming and labor-consuming. Or adopts extensive spraying, causes water source waste and has extremely low utilization rate. Lack of consistency.

Furthermore, another mode of the existing roof greening is seedling planting greening of a root control device, small holes are distributed around the root control device, a user directly waters water into the root control device, the water can directly come out from the small holes of the root control device, the surface of the tree root is wet, the bottom of the tree root is dry, and the defects of time and labor waste and extremely low water source utilization rate exist.
