What is the hardest tree in China?

At present, there is no exact measurement of the tallest tree in China, but it is generally believed that the Wangtian tree in Xishuangbanna, Yunnan Province is the highest tree species in China, and the Wangtian tree is also called the "Qingtian Tree", which is about 40-60 meters high, because it grows straight and straight, and the height is much higher than other trees, so it has the reputation of "giant in the forest" and "beauty prince in the forest".

The growth habits of the Wangtian tree.

The seeds of the tree are not easy to collect, and their seeds fall to the ground, where they germinate or decay quickly, and usually grow in moist valleys, slopes, hills, and lime mountain forests.

It was discovered in 1975 by a forestry expedition from Yunnan Province, China, in the forests of Xishuangbanna, and is now found in Yunnan, Guangxi, and some tropical rainforests in Southeast Asia.

At present, the Tropical Botanical Garden of the Kunming Institute of Botany, Chinese Academy of Sciences has cultivated the Wangtian tree, and a nature reserve has also been established in the production area of southern Yunnan.

In the tropical jungle of Xishuangbanna, Yunnan Province, China, a kind of giant tree was found in the 70s, its beautiful posture, towering and straight trunk, standing tall and tall on top of ten thousand trees, making people unable to look up to see its top, and even the sensitive altimeter is useless here Therefore, people call it the Wangtian tree The local Dai people call it"Umbrella tree"｡

Wangtian trees can generally be about 60 meters high People have measured and analyzed a tree, and found that the Wangtian tree grows quite fast, a 70-year-old Wangtian tree, is more than 50 meters high Some are even as high as 80 meters, the diameter at breast height is generally about 130 centimeters, and the maximum can be 300 centimeters These giant trees that are rare in the world, one by one towering in the upper layer of the valley rainforest, are generally more than 20 meters higher than the second layer of trees, and they really have the momentum of going straight to the nine skies and piercing the blue sky!

Wangtian tree belongs to the dipterocarp family, Liu'an belongs to this family, there are 11 members, most of them live in Southeast Asia Wangtian tree only grows in Yunnan, China, is a rare tree species that is a specialty of our country Wangtian tree is tall and straight, the leaves are alternate, there are pinnate veins, and the yellow flowers are arranged in panicles, exuding bursts of fragrance Its fruit is hard Wangtian tree generally grows in 700-1000 meters of valley rainforest and mountain rainforest, forming an independent community type, showing a peculiar natural landscape Therefore, Academics regard it as a symbol tree species of the tropical rainforest

Wangtian tree material is excellent, rapid growth, high productivity, the trunk volume of a Wangtian tree can reach cubic meters, the average annual growth of a single tree is 2-3 times that of other tree species in the same forest, so it is a good tree species worthy of promotion At the same time, its wood is rich in gums, flowers contain spice oils, and many other unknown components, which need to be further analyzed and utilized

Because the Wangtian tree has such high scientific and economic value, and its distribution range is extremely narrow, it is listed as a first-class protected plant in China

There is also a very close one in the Wangtian tree"Twin brothers"It is actually a variant of the Wangtian Tree, which was also discovered in Guangxi in the 70s The shape of the Optimus Tree is extremely similar to its brother, and it is also extremely tall, often reaching 60-65 meters, and the height under the branches is more than 30 meters Its material is hard and corrosion-resistant, and the planing surface is smooth and clean, the texture is beautiful, and it has extremely high economic value and scientific research value The Optimus Tree is only found to grow in the Langgang Nature Reserve in Guangxi, so it is also strictly protected

What is the tallest tree in the world?

<> largest tree in China is in Yingjiang County.

Copper wall off the old knife.

Next to the village. Its tree is extremely large, and dozens of people can't hold it. Its trunk is covered with blocky root systems, such as mountains, canyons, thousands of ravines, and bunches of aerial roots are thrown from the tree poles, like giant pythons.

Dig your head deep into the dirt, as if to suck all the moisture out of the ground.

A tree can also be defined as a tree made up of root nodes and a number of subtrees. A tree is made up of a set and a relationship defined on that set.

The elements in the collection are called the nodes of the tree, and the relationships defined are called parent-child relationships. Parent-child relationships establish a hierarchy between the nodes of a tree. There is a node in this hierarchy that has a special status, and this node is called the root node of the tree, or the root of the tree.

3. The production area of iron birch is not wide, mainly distributed in the southern part of North Korea and Vietnam, and the border area of North Korea and China, as well as the coastal area of southern Russia. Stool tracks.
