In Guizhou subtropical evergreen broadleaf forest , the tall and upright Nanmu can always attract people's attention. It is national second-class protected plant and is one of the top woods. The ancients called nanmu "gold among woods", nanmu, camphor, zira, and sandalwood were called "four famous woods", and nanmu ranks first. Nanmu "water cannot soak, and ants cannot cave". The ancients often used Nanmu to make coffins or plaques. Nanmu must also be used as the "branch materials" of royal palaces and important buildings.
Nanmu Forest
0 The seeds of Nanmu will depend on the power of the wind or the transport of birds and animals to be scattered among the grass. When Nanmu was born, it grew very slowly. In the face of weeds, this future "branch" is bullied, and the invasion of insects, or damage caused by birds and beasts, may kill it. The seedlings of nanmu cannot grab the sun, rain and dew. They live hard, but they know how to endure and how to exchange time for for space.
The life of nanmu seedlings is tenacious enough to know how to hide their strength and keep a low profile. It takes advantage of the time difference between weeds and grow and grow, and strives to grow taller through the gaps of weeds. It is not in a hurry to open its canopy, because opening the umbrella-shaped canopy too early will affect its height. It desperately expands its vessels when it is rainy and shrinks to preserve moisture when it is dry. Therefore, the annual rings of Nanmu have different shapes. The ancients said: "The most beautiful nanmu may form the mountains and rivers of people facing the sun." Nanmu faithfully wrote the pain and joy of his growth in the annual rings.
When the nanmu grows tall enough, its domineering aura is revealed. After the nanmu trees standing side by side formed a forest, they opened their canopy, like big umbrellas covering the sky and the sun. When the canopy is completely closed, the sunshine and rain of the weeds under the forest are taken away, and the weeds that have bullied them in the past are gradually eliminated.
Birds of a feather flock together. When nanmu grows into a landscape in subtropical evergreen broad-leaved forests, the species that can be compared with them are the tall tan tree , qinggang oak , qinggang, fine leaf green hill, etc. They stand on the top of the mountains in Guizhou, eat wind and drink dew, share weal and woe with the mountains and rivers, and have the spirit of the heroes in the world who are the only ones.
Nanmu is very picky about the growth environment. Its growth environment should be warm and humid, with annual precipitation between 1400 mm and 1600 mm, and the temperature should be between 0℃ and 38℃.
An ancient nanmu tree in Siyetun Nature Reserve, Sinan, Guizhou has a bust of 8.92 meters, a canopy of 16 meters, a height of 45 meters, and a age of over 1,300 years old. It is called " Nanmuwang ". Around this "Nanmu King", there are more than 150,000 wild Nanmu trees, mainly concentrated in the two townships of Qinggangpo and Yangjiaao. Sinan has thus become the "Nanmu Town".
