Nanjing is a famous green city. The reason why it can be so is that it owes all the credit to the plane trees.
The plane tree is a deciduous tree, up to 35 meters high. There are rows of sycamore trees on both sides of our street. They have broad crowns and strong trunks. Leaves are large and can also be clipped into books to make bookmarks. They are truncated or near-cordate at the base. Spherical inflorescences usually have two clusters, which resemble hanging bells. Flowers are about 4 mm long, male flowers have 4-8 stamens and female flowers have 6 segregated carpels. When spring comes, we will see a lot of wool fall from the tree, that is the fruit of the sycamore tree.
Ficus Tree is an important garden greening tree species in China, which can be planted on lawns, residential areas and streets. It not only has strong resistance to sulfur dioxide, but also can be used for greening in factories and mines. The value of plane trees is not small. It can be used to make musical instruments and furniture; seeds can be edible and oil can be squeezed; bark fibers can be used as paper-making raw materials; leaves, flowers, fruits and roots can be used as medicine, which has the function of clearing heat and detoxification.
When the hot summer leaves the warm spring, the leaves and branches of the sycamore trees gradually flourish, and these trees Nestle together, almost covering half the sky. At this time, the broad road immediately turned into a shady path. Nearby residents often come to the community with a small chair under the sycamore tree, sitting under the tree to chat about everything, as if they want to spit out their troubles quickly in this comfortable environment.
Autumn has come, and there are numerous deciduous leaves outside. The plane tree is no exception. When I see those fallen leaves, I will think of one of the most famous poems: "Wutong knows autumn all over the world from a fallen leaf of Wutong", which means that the world has entered a cool autumn.
Wutong tree, it is so dedicated. Every day, it is the first to usher in the dawn and the last to send away the night. When the earth is asleep, they are still like loyal guards, always guarding both sides of the road. Like a city cleaner, it absorbs the exhaust gas from factories and automobiles all day long, spits out fresh oxygen, and does its duty and duty to beautify the city; plane tree, it is so selfless. It would rather be exposed to the sun than shade for us; it would rather be exposed to the rain for us. It is not afraid of the severe cold and heat, and has no desire for people, but contributes its whole body and mind and strength to people. Wutong tree is really a characteristic of Nanjing!
