Do these trees have special functions even though they are still tall and tall in the water all day long?

Recently, A Quan sent a photo of a spring outing on the East Lake to Mr. Squirrel, which was supposed to show the legendary Canon Green (it is said that Canon camera shot plants without saying, bring its own Canon Green). Squirrel Jun was suddenly attracted by the pond fir tree behind him. Handsome! Soaked in the water is also a good-looking watch, this tree must talk about, so there is today's article.

The place with Cunninghamia lanceolata always shows the beauty of the primeval forest and exudes the smell of moist rosin all the time. It's like crossing to Jurassic Park for fear that a few jaw dragons will sneak up on you from behind the tree. It is said that Chi Sequoia is really witty and capable, and their tree shadows can be seen in swamps and wetlands. And standing in the water all the year round, aren't you afraid to make your feet swollen?

Chi Sequoia has its own wonder: missing is the pain that can breathe, and the root of knee is the root that can breathe!

With regard to the water station of Cryptomeria fortunei, it is still green, and it is about to lead to its special function. Here we would like to introduce a concept, knee root plant. Yes, our sequoia is such a plant, and thanks to this special root system, it can thrive. The so-called knee root is also a kind of respiratory root, which is also classified as a kind of abnormal root in the classification of plant roots. It is like the breathing root hanging from the branches of a banyan tree, except that the knee root of the pond fir grows in a different position. At present, plants with knee roots are rare, and the most typical ones are Cryptomeria fortunei, Cryptomeria fortunei and Pinus elliottii.

Knee roots are most common in plant roots growing in moist swamps. Because of the humid environment and poor air, the plants are caught in asphyxiation panic, and the water from the swamp flows slowly from the roots, which seems to be extremely negative, but it is a disaster for plants. Submerged in the water will lead to serious lack of oxygen in the roots.

So the knee root plant, in order to avoid the death of the root system, the root, which is in full contact with water, makes a physiological stress response. The root grows a number of reverse cells in order to let the root grow to the surface of the water. Other tree species are constantly deep down the root, and they try to grow vertically up until they come out of the water and breathe fresh air.

The knee root is very interesting, with various shapes, some like bamboo shoots unearthed, some like stalactites formed by karst caves, and some crying and laughing like Buddha's feet. Most of the knee roots are dark brown and brown-red, and their internal structure is very ingenious, with many well-developed airways, conveying air all the time, ensuring the breathing of plants, maintaining life, and storing and transporting nutrients to ensure growth.

The cider trees in these places are scenic all the year round, but you don't know it yet!

The big wild goose pond is warm in spring, and the fir sees the egret.

The Dayantang Reservoir in Chengxing Village, Ketan Town, Lujiang County, Anhui Province, has planted more than 20,000 cedars in the Dayantang Reservoir, so that the ecological environment of the water forest has been restored, and birds gather and play in the dense fir forest, showing a scene of ecological harmony. Sequoia sprouted egrets inhabit and breed. The scenery must be very beautiful. I will go again next year.

Summer tour Mountain General, Chi Sequoia accompany plank road

Nanjing Mountain General Scenic spot can proudly call itself "Nanjing Jiuzhaigou" and "the first scene of Jinling". The most unique scenery is Shanqiao twists and turns, clear water and forest. Tall and straight fir trees have sprung up on the surface of the lake. The water is calm and clear as a mirror, and the fir trees are planted upside down in heaven.

It is cold in autumn in Dalian Lake, and the pond fir makes light and shadow.

Dalian Lake National Wetland Park is located near Qingpu Xicen and Liantang. The fir is in the water, the water is mixed with wood, the tree is in the water, and the scenery on the shore attracts eyeballs. The morning light is shining at the top of the tree and the dizzy bouncing mirror in the water.

Winter memories of Bamboo Town, Chi Shan Opera Ducks

Bamboo Town, a small town northwest of Liuhe in Nanjing, bordering Lai'an County, Anhui Province, is a newly developed 10,000 mu forest park with lots of peach trees, chestnut and rape. What must not be missed in winter is a piece of cedar in Zhimaling scenic spot reservoir, where there are few people, patches of sequoia stand in the water, and ducks swim in the water.

Recently, Mr. Squirrel envied his friends in the south very much. A few days ago, Ah Quan said, "Mr. Squirrel, look at the moss all over the ground, and the grass is sprouting!" And look at the green space downstairs. Spring blossoms have begun a new round of peach and apricot plum silly season in the south, while the petals of the northern plum blossom have just been swept away; when the southern partners began to swim the sea of rape flowers, the northern primrose braided; now the southern tulip hyacinth competition ushered in countless people stop, the northern mountain peach just white treetops.

Welcome to follow the plant fans, the Squirrel is still here to enjoy the flowers and plants with you!
