Fa Tong, that is, French plane tree, also known as hanging suzuki, shinaomu, pure land tree. It is a deciduous tree of the family Suzukiaceae. The leaves of the Paulownia are thick and green, and they are mostly used as street trees. In the heat of summer, the rich canopy of the tree is like a parasol, sheltering the sun, evaporating water vapor, increasing humidity and reducing heat, cooling and dispelling heat, making the environment cool and elegant, and reducing the pain of pedestrian heat. Some places call it the "sweat removal tree", which is worthy of its name.
It is native to North America, southeastern Europe and western Asia, India, and the Himalayas. Mainland introduction has a long history. Now the main varieties introduced in the mainland are French plane tree (also known as three-ball hanging suzuki, the fruit order is actually 3~6 in a bunch), British sycamore (also known as two-ball hanging suzuki, fruit balls are usually 2 in a bunch, occasionally single or 3 in a bunch) American sycamore (also known as a ball of sycamore, fruit balls are often single, occasionally two in a string) three. It is common for people to see that most of the trees on the streets have short branches and broad canopies and are cup-shaped. This is the result of manual refurbishment. It is a tall, majestic tree that can reach a height of up to 5 meters. In adolescence, the tree is ovate and conical.
It is not only an excellent street tree, but also an ideal tree for purifying the air, blocking noise, and greening the factory area. Paulownia has large leaves, hairy backs, a broad canopy, and a strong ability to retain dust. For example, the Paulownia forest belt with a width of 20 meters, a height of 15 meters and a closure degree of 0.9 can block dust by 35~60%; The Paulownia forest 200~250 meters away from the pollution source can absorb 3.5~4 grams of dust per square meter of leaf area. The anti-noise effect of Fatong is also quite good. It also has a strong absorption capacity for harmful gases such as sulfur dioxide, hydrogen fluoride, chlorine, and lead vapor.
Because it can adapt to various soil conditions, it is resistant to drought and barrenness, and resistant to water and humidity, and is suitable for planting and utilization under urban conditions. Therefore, it has become a beautiful street tree and garden tree recognized all over the world. It is popular all over the world and has long been known as the "King of Street Trees".
