Platanus acerifolia is a new tree species introduced to China from the United States more than 0/00 years ago. Now it is planted all over China, especially in Shanghai, Nanjing, Xuzhou and Suqian. Platanus acerifolia likes warm and humid, grows very fast and has lush leaves, which can purify the air environment. It is a kind of tree planted beside rural and urban roads, which can not only shade the sun, but also purify the air and beautify the road. Platanus acerifolia is suitable to grow in a slightly acidic soil environment with good drainage system, and it is easy to cause yellowing of leaves when growing in acidic soil. Its root system is underdeveloped and it is easily blown down by strong winds. Its ability of gas evolution is very strong, and its leaves can absorb toxic and harmful gases and dust in the air. Because of its high height, fast growth and good feeding, it has been widely planted on both sides of roads in recent years.
