Speaking of Nanjing, the most impressive is the trees in Nanjing. Whether it's flowering or not, it's hard to forget. On the wide road, there are tall Wutong, cedar, ginkgo trees. The green promenade has been built, and my favorite love is the tall Indus tree.
A tall and tall Wutong tree stands at the gate of our school. The trunk is so thick and straight that the tree top is so high. It is like a PLA uncle standing guard for us, defending our beautiful campus. I walk past it every day when I go to school or after school. It gives me a sense of security.
When the spring girl came, the phoenix tree began to sprout. Under the sweet spring rain, the buds gradually grew into green leaves. As if they had seen a small head from the trunk, they were struggling to see the beauty of the spring. A wild profusion of vegetation packed closely layer upon layer of leaves in the summer. The leaves of the large fan clusters are dense and dense. There is no gap left in the trees. The leaves of the green trees are like a big green umbrella, bringing us cool summer. The students like to enjoy the cool, chat and play under the tree very much. A gust of wind blowing, leaves issued a "rustle" sound, like singing to us.
When autumn came, the phoenix tree began to shed its leaves, and the bright, green leaves gradually darkened, turned dark green first, and then turned from dark green to yellow. When the wind blows, the leaves whirl and dance gracefully. The fallen leaves become very fragile. When you touch them with your hand, they break into small pieces.
Winter came, and the leaves of the trees fell, and the Wutong tree became bare branches, but still stood in the cold wind. After a winter snow, snowflakes fell on the Indus tree, which was like putting snowy white clothes on the Indus tree, and dressing up the bare tree of trees as a guard standing on the snow.
Look, this is my love of phoenix tree. Phoenix tree I walked into the school, on my left is a row of tall, thick, Indus trees. These sycamore trees are like a sentinel, and like giant mushrooms, like an umbrella.
In spring, the phoenix trees grow new leaves, as if there is a new life trembling on every tender yellow leaf.
In summer, the leaves of the parasol trees are stacked on top of another cluster, without a gap. The sun is shining on the leaves. Look at those leaves. They are enjoying the sunshine!
In autumn, the leaves began to turn yellow, as if aunts' hair turned yellow gradually. From time to time fell a few leaves, these fallen leaves like butterflies in the air, like swallows in the air.
In winter, the leaves of Chinese parasol trees fall fiercely. Take another look at the blanket with a thick layer of leaves on the ground.
How tall the plane Wutong tree is, oh! It left a deep impression on me! Wutong Wutong, I believe you are not strangers. There are so many tall and big Wutong trees near my house.
Their leaves grow particularly neat, bark gray green live gray white, and particularly lush, dense layers. Whenever spring is always green and green, it draws out new branches and grows bright yellow flowers. It seems to bring us joy of spring; in summer, the sun is shining on its leaves as if it shines on gold, which makes people feel so beautiful and so energetic. Wutong, some of the parasol leaves are green, but obviously not as green as they used to be. They had already turned yellow, and even fell to the ground; winter came, and the wind grandfather came, and they all began to dance, and soon all the leaves were gone, leaving only the thick trunk. But I love it very much in spring, summer, autumn and winter.
The longevity of Wutong tree is generally over 100 years. Flowering period is from 4 to May. The head is inflorescence, and the male flower has 4 - 8 pistils. The female flower has 6 separate carpels, and its fruit ripening period is from 9 to October. The value of Chinese parasol tree is very high. It not only beautifies the environment, purify the air, but also has its seeds edible, it can also extract oil, and it can also be used for medicinal purposes. It has the functions of referencing flavor, Gan, Ping, non-toxic, functional tonifying qi and nourishing yin, improving eyesight and smoothing liver, black hair, and clearing away heat and detoxicating effect.
After listening to my introduction, you probably know something about the external characteristics or value of Chinese parasol tree. Well, you also try to observe the parasol tree beside you. The trees arranged in a crisscross pattern of tall trees. They don't know how much hot sun they have experienced. Welcome to wechat: www 4hw for more knowledge. How many blows of wind, rain, snow and frost finally stand on both sides of the street.
As the bell rang for the new year, spring girl came to the world with a hint of coolness. She gave the green to the phoenix tree, which made the Indus tree bare and bare. The tender bud comes to the world again, and presents the most brilliant smile to the world.
In the hot summer, the warm spring was sent away, and the branches and leaves of the Indus tree grew luxuriant. At this time, the broad road, immediately turned into a cool path. Nearby residents often carry a small chair, sit under the Wutong tree, chat without any problem, as if they want to spit their troubles out in this comfortable environment.
When the autumn wind sweeps the fallen leaves, soon the dark green leaves gradually turn yellow, turn yellow, and finally fall down due to dryness. People often find that the wind blows the withered and yellow leaves all over the sky, and decorates the bare trunks with extraordinary beauty. At this time, it seems to be telling: I hope the next spring will come soon.
Wutong tree, you bring people cool, you bring beauty to the streets, you add beauty to the world! Phoenix tree, today I will introduce the phoenix tree.
Chinese parasol tree, the Chinese parasol tree, is a plant of the genus Indus China. It is also known as the Chinese pine tree and tung tree. It is also a large deciduous tree, usually up to 15 meters tall, with straight trunk and smooth green bark. It is native to China. It is cultivated in North and South provinces. It is also a common street tree and garden ornamental tree. What we call the French plane is actually a species of sycamore.
The leaves of sycamore tree are very similar to maple leaves. The leaves of Wutong trees will change color. In spring, the leaves are green; in autumn, the leaves turn yellow. Why? It turned out that in summer, the leaf worked very hard, but when the weather turned cold, it stopped working. The nutrients produced by the leaves are not sent to the branches and trunks, but deposited in the leaves. The chlorophyll of the leaves will also be destroyed, which will be mixed with the nutrients left in the leaves or the withered tea brown, so as to become a variety of beautiful colors. All the leaves contain green chlorophyll. The trees use chlorophyll to capture light energy and store the light energy in the form of sugar and other chemicals with the help of other substances in the leaves. In addition to chlorophyll, many leaves also contain yellow, orange, red and other pigments. Although these pigments can not carry out photosynthesis like chlorophyll, some of them can transfer the captured light energy to chlorophyll. In spring and summer, the content of chlorophyll in the leaves is much more abundant than other pigments, so the leaves show the green color of chlorophyll, but can not see the color of other pigments. When autumn comes, the days shorten and the nights lengthen, which makes the trees begin to fall. Before falling leaves, trees no longer produce a lot of chlorophyll as they do in spring and summer, and existing pigments, such as chlorophyll, gradually decompose. In this way, with the gradual reduction of chlorophyll content, the colors of other pigments will gradually appear on the leaves, so the leaves will show yellow, red and other colors.
The value of Chinese parasol tree is also great. Phoenix tree is an ornamental tree cultivated in the garden. The wood is light and soft, which is a good material for making wooden boxes and musical instruments. Fried seeds can be used as edible or pressed oil, and the oil is non drying oil. The root bark, stem, leaf, flower, fruit and seed can be used medicinally. It can treat diarrhea, hernia and hair whitening. It has the effect of clearing heat and detoxifying. The fiber of bark is white and can be used for papermaking and rope weaving. Wood flakes can leach mucus, which is called shavings.
Wutong seed is the seed of Wutong tree. Harvest from late autumn to early winter, remove impurities and dry in the sun. The dried seeds are spherical or quasi circular, 6-8 mm in diameter, yellowish brown to dark brown, and the surface shrinks to reticulate. The outer testa is brittle and easy to break, while the inner testa is tough. After removal, there are two thin and large cotyledons close to the endosperm, and the radicle is located at the narrower end. The taste is even and slight. It is better to be big, full, brown and free of impurities. Tao lived in seclusion and said, "there are four kinds of tung trees. Phoenix trees are white and leaves are like Wutong trees, but there are sons and children who are also able to eat fat. Li Shizhen said, "Wutong is everywhere. The tree looks like tung tree, but its skin is green. Its wood grows straight without knots, and its structure is fine and tight. The leaves are small, smooth and pointed. Its flower is thin, falling like a flower. Its pods are about three inches long, five pieces of them are made up, and when they are old, they crack like a dustpan, which is called gaoe. Its sons are attached to the Ligusticum and Hubei, most of them are five or six, few or two or three. The seed is as big as pepper, and its skin is wrinkled. Its son, Ganping, is nontoxic
Wutong tree is like this. Phoenix tree today is Sunday. I do my homework and have nothing to do. I walked out of my house and saw the Wutong tree in front of the door. Wow, the Chinese parasol tree I saw today is quite different from the Indus tree that I saw before. Today, I saw the Wutong tree trunk is really strong. I only hold half of it by myself. I think it will be possible for mother to be able to hold this Indus tree. I'll look at the whole tree. Ah, it's also very tall, almost as tall as a five or six story building. High enough! Its trunk is very rough, and my hand itches, so I rub it against the trunk. The itching on my hand soon stopped. If you look at the tree carefully, there is a bulge here and a dent there. It's very ugly. The bark of the tree is out of the ordinary, and some are like the skin of football, and some are like... The branches of the Chinese parasol tree twists and turns, forming a very large "hand". It seems to be a large umbrella umbrella skeleton, extending to the four sides, where the leaves are just full of gaps, forming a big umbrella, covering up a piece of blue sky, so that the sun can not shoot down to the ground.
In summer, I play games, cool and chat with some children under this big Wutong tree. It's a good place for us to visit! In autumn, we came to pick up some leaves on the ground and picked up some bookmarks.
I love this Indus tree, I love nature!
