Question 1: What are the characteristics of trees? Generally speaking:

1. Trees can adjust the climate and maintain ecological balance. Through photosynthesis, trees suck in carbon dioxide and exhale oxygen, making the air clean and fresh. One acre of forest gives off enough oxygen for 65 people to breathe.

2. Trees can prevent wind and fix sand, conserve water and soil, and absorb all kinds of dust. One mu of forest can absorb 2-6 tons of dust a year.

3. Woods can reduce noise pollution. A 4-meter-wide forest belt can reduce noise by 1-15 decibels. Noise pollution has caused great harm to human life, study, work and rest, and can be said to be people's "enemy". Therefore, we should pay more attention to afforestation. Noise can also cause hearing loss, deafness and stupidity, and abnormal heart, blood pressure and nerves in long-term life. Even, it can make people die under the long-term noise. In this way, afforestation can reduce noise by four or five times.

4. The secretion of trees can kill bacteria. There are 34, bacteria per cubic meter of air in the open space, and only 3,4 bacteria in the forest. Planting trees is the obligation of every citizen, and the state has specially designated March 12 as Arbor Day. Afforestation is of great benefit to our study, work and life.

5. Afforestation can purify the air, beautify the environment, green the motherland, etc. It can also make oxygen for people to absorb and breathe in the carbon dioxide exhaled by people. If a large number of trees are not planted, then the oxygen on the earth will be difficult to meet the needs of human beings and various creatures.

question 2: what are the characteristics of any tree? There are many kinds of trees with many characteristics, some are flowering, some are fruiting, and some are used as building materials ......

Question 3: What are the characteristics of big trees? Big trees are flourishing, which can provide shelter for birds, absorb a lot of carbon dioxide, release a lot of oxygen, protect soil and prevent soil erosion.

Question 4: What tree has what characteristics? Lantern tree

This is a deciduous shrub of Ericaceae. Growing in the central part of China. It is only 2-6 meters high. Every summer, there are more than a dozen meat-red bell-shaped flowers hanging on both sides of its branches, so it is also called bell-shaped flowers. The fruit of the lantern tree ripens in October, oval and brown. Interestingly, its peduncle hangs down and its apex bends up, so the fruit is upright. From a distance, it seems that the branches are full of small lanterns, hence the name. The lantern tree is not only beautiful in flowers and fruits, but also leaves turn deep red in autumn, which is not like maple leaves, but better than maple leaves. Therefore, it is a very promising garden ornamental tree

Badminton tree

In some mountainous areas in central and southwest China, there is a small low tree growing. Whenever the fruit is ripe in October, from a distance, every tree is full of fruits that look like badminton, and people call it badminton tree. Badminton tree belongs to Santalaceae. Although it is only 1-3 meters high, it is flourishing. Its fruit is only about 1 cm in diameter, but each fruit has four bracts 3-4 cm long at the top, which looks like badminton. It is said that its fruit is edible. Badminton tree is also a semi-parasitic plant, and part of its roots are parasitic on the roots of pine and fir plants. Part of the nutrients it needs for its own life is obtained by absorbing the nutrients of these plants.

Question 5: What are the characteristics of big trees? Trees with DBH ≥25px or shrubs with tree height ≥4m are called big trees.

Transplanting characteristics of big trees:

1) Tree species in villages and mountains: Most trees are transplanted from mountains and villages. Most of these tree species are seedlings which germinate by seeds. The taproot is developed, and the capillary root is far away from the tree body. Transplanting causes great damage to the root system, which is not conducive to survival. Especially the trees on the mountain are not conducive to carrying soil balls, and it is more difficult to survive and the mortality rate is higher.

2) Tree species for urban renewal: In order to expand green space, roads and demolish urban villages, the original trees are planted in other places. These tree species generally have a high survival rate.

the maintenance of happy forest makes it easier to transplant big trees.

question 6: the characteristics of a big tree are five points: tall, tall, leafy, deeply rooted, growing for a long time, big shade, thick stem, many fruits, pity, confidence and arrogance. Selfless, strong, calm the wind and sand. Proud, guards, rings. Smooth

Question 7: What other trees do you know? What are their characteristics? Characteristics of Cinnamomum camphora

Cinnamomum camphora can green the environment and beautify life, and it can benefit human beings.

Cinnamomum camphora not only can prevent insects and moth, but also has many irreplaceable effects. Ancient physicians in China have long studied and practiced the medicinal use of Cinnamomum camphora. Li Shizhen, a master of Chinese herbal medicine in China, recorded 1,892 kinds of medicines in his life, and among the more than 1, prescriptions he collected, there were records about the medicinal use of Cinnamomum camphora. If you use camphor tree wood to decoct soup, you can "bathe beriberi and itch"; Using camphor wood as wooden slippers can remove beriberi; "Hand and foot gout: cold pain like a tiger bite." "Use a bucket of camphor wood chips, a stone in the rushing water, fry it extremely and boil it, and put it on the bucket by heat." Li Shizhen's record has been extremely consulted and widely used for more than 5 years.

Maybe you like the tall and straight pine trees, maybe you like the ginkgo tree, the birthday star of the Millennium, but I like the common camphor trees on the roadside, because they accompany me to school in the morning light and send me home in the sunset light.

Cinnamomum camphora is an extremely precious tree species. Because Cinnamomum camphora has strong cold tolerance, fast growth, dust absorption and strong resistance to air pollution, it is almost always Cinnamomum camphora on the roadside.

In spring, when the east wind blows, camphor trees will sprout new tender leaves. At the beginning, it was just hairy buds, showing a little light green. Within a few days, the tender leaves were all exposed from the bud. At first, it was just two opposite light green leaflets, and a little one occupied the top of the branches of the tree. The new leaves grow up and the old leaves begin to fall off. If there is wind, large tracts of leaves will be like snowflakes, drawing an arc in the air and falling to the ground. At the end of the day, there will be a thick layer of fallen leaves under the tree.

My good friend Chun said that there are several big camphor trees in her house. After I heard about them, I went to watch them with some good friends.

pure camphor tree is not tall, but it is very strong. Flourishing leaves, dense leaves are bright green, and the approximate oval green leaves are deep and light in color: vermilion, light green, dark green, It's very beautiful. After a closer look, I found that the leaves seemed to be covered with a layer of wax, which was really like a handicraft carved by amber or jade. At noon, the sun was strong, and the shiny leaves shook my eyes.

I picked a leaf and rubbed it gently, and a thick natural fragrance came to my nose, which made me feel refreshed. I gently picked a few camphor leaves and put them in the book as bookmarks, so that not only the book would be filled with a faint fragrance, but also the book would not be easily eaten by insects. Because camphor tree itself has an insect-repellent aroma, and this aroma can be maintained for a long time, even if the leaves wither, its aroma remains unchanged, as long as it exists for one day, insects are afraid of it for one day.

Peach trees, pear trees and other trees will bloom, and camphor trees are not included. The flowering period of camphor trees here is usually around April and May, and the flowers of camphor trees are very small and arranged in panicles. Although it is not as beautiful as peach blossom and as beautiful as peony, it deeply attracts me. A string of yellow-green flowers are quietly dotted among the leaves, emitting a faint fragrance. A gust of wind blows, and a pleasant fragrance suddenly gets into the nostrils, making people feel refreshed and relaxed. The flowers of Cinnamomum camphora not only attracted me deeply, but also attracted swarms of bees and butterflies. They danced among the flowers, which was really lively!

In July and August, the clusters of beautiful flowers turn into clusters of light green fruits. When the spherical fruits are ripe,

they will turn into dark purple, and sometimes even attract some birds to scurry around the trees, scrambling to peck, and occasionally make a pleasant call, which constitutes a "bird pecking map".

On the day of the month, the camphor trees on the way to school sent me out early to welcome me back late. Before I knew it, I was about to graduate from primary school, and the colorful childhood was slowly fading away in their images of falling leaves and green branches.
