Embodiment 1
[0018] The following is a detailed configuration process and application process through the implementation of use cases
[0019] Artificial soil for roof greening planting S. japonica: 15% of fermented sludge, 15% of desulfurized gypsum, 30% of perlite, 30% of straw, and 10% of cinder soil. The sludge from Tianjin Jizhuangzi Sewage Treatment Plant was transported, fermented and decomposed, and then air-dried to a water content of about 10%. The desulfurized gypsum was from the No. 1 Thermal Power Plant, and air-dried to a water content of 15%. The perlite was purchased from Xiqing Industrial Park, with a particle size of 2mm -5mm, the straw is the corn straw purchased from Ninghe County, the length is 8cm after drying and crushing, and the cinder is collected from the residential area, and the above materials are mixed according to the mass ratio, and the mixture is evenly mixed. Roof greening must be laid with waterproof layer, water-proof layer, and water storage layer acco...
