Example Embodiment

[0020] Example 1

[0021] A green roof substrate, the main composition of the substrate is: 35% biogas residue, 8% vermiculite, 30% plant fiber, 22% acrylamide-acrylate copolymer cross-linked product, and 5% earthworms.

[0022] Furthermore, the plant fiber is a powdery solid mixed with reed stem, platycodon, and rice husk.

[0023] Moreover, the water content of the substrate is 40%, the organic matter content is 25%, the total nutrient content is 3%, and the pH value is 7.4.

[0024] In addition, the method for using the roof greening substrate is to mix the components uniformly in proportion, spread the substrate on the greening planting area of ​​the roof, lightly compact after spreading, plant green plants, and water .

Abstract

The invention provides a roof greening substrate. The roof greening substrate is characterized in that the substrate is mainly composed of biogas residues, vermiculite, plant fibers, acrylamide-acrylate copolymer crosslinking matter and earthworms. The roof greening substrate is loose, high in water content, sufficient in nutrient and suitable for roof plant growth, and the pH value is neural.

Description

technical field [0001] The invention relates to a substrate for greening, in particular to a roof greening substrate and a use method. Background technique [0002] With the process of large-scale urbanization, the scale of cities continues to expand and the urban population continues to increase. Buildings are getting taller and denser, forming a large number of "urban deserts". However, the area of ​​green land, which plays a role in regulating the urban ecological environment, is gradually decreasing, which eventually leads to the deterioration of the ecological environment, and many environmental problems such as the "urban heat island effect", "greenhouse effect", and air pollution have emerged. One of the trends in the development of architecture now is to coordinate the architecture with the natural environment and introduce more green space into the building space. Roof greening technology has this feature. [0003] Roof greening is a special form of greening. It is...
