What are the characteristics of Parthenocissus
In a reinforced and concrete city, there is always a touch of green winding up the walls, outlining the outline of the building with natural brushstrokes. What kind of survival wisdom does this creeper, known as the "wall magician", hide? Let us reveal the mystery of vertical greening through its unique structure and ecological value. The evolutionary miracle of the natural engineer's suction cup structure climbing on the wall The sucker-like structure at the end of the tendrils is the unique weapon of the creeper. Each suction cup can generate an adsorption force of about 1.3kg. These natural suction cups secrete special mucus, form a molecular bond with the wall, and can grow steadily even on glass curtain walls. The complex vascular bundle network inside the sucker can be seen under the microscope, achieving efficient transport of water and nutrients. The survival philosophy of environmental adaptation ranges from extreme temperatures of minus 25 ° C to 40 ° C, from acidic soil with a pH of 4.0 to alkaline lime walls, the creeper has shown amazing adaptability. The cuticle of its leaves can be three times as thick as ordinary plants. The root system can secrete organic acids to dissolve minerals, and nutrients can also be obtained in building gaps. The three-dimensional builder of the ecosystem, the expert on microclimate regulation. The 10㎡ creeper wall can lower the room temperature by 3-5 ° C in summer, which is equivalent to the continuous operation of three air conditioners. The dense leaves form an air filter layer, with an adsorption efficiency of 1.2 g/㎡·day for PM2.5, and the noise reduction effect is equivalent to a 30-cm solid brick wall. The vine network of the biodiversity shelter provides a habitat for 38 species of insects and 12 species of birds. The annual accumulation of litter reaches 0.8 kg/㎡, forming a unique vertical decomposition system. The case of Beijing Siheyuan shows that the number of organisms on the walls covered by creeper has increased fourfold. What are the characteristics of the green art of urban space creeper
From the blue bricks and black tiles of ancient Jiangnan towns to the glass curtain walls of modern buildings, the creeper uses the changing color spectrum of the four seasons to interpret the aesthetics of space. The goose yellow sprouts in spring, the emerald curtains in midsummer, the red makeup in late autumn, and the iron wire and silver hooks in winter form a breathing architectural coat.
This ancient climbing plant is returning to modern cities with the dual attitude of technology and aesthetics. It not only reshapes the temperature of buildings, but also inspires us that ecological wisdom is often hidden in the simplest laws of nature. When buildings and plants form a symbiotic system, the cold walls have the rhythm of life.
