[Explanation] In the beginning of winter, the thousand-year-old ginkgo in Huangsi, Fuquan City, Qiannan Buyi and Miao Autonomous Prefecture, Guizhou Province, ushered in the best viewing period.
The huge ancient ginkgo among the mountains and the golden leaves on the ground has become a unique local scenery, and many tourists come to check in.
Recently, the reporter visited and felt the life miracle of the world's oldest ginkgo tree for more than 5,000 years.
[Explanation] The tree is 50 meters high and the canopy covers more than 600 square meters. 13 people can hold hands to hug it. According to relevant data, this ancient ginkgo tree is more than 5,000 years old and was included in the Guinness Book of World Records in 2001. , Is the most ancient ginkgo tree recorded in writing.
[Explanation] Walking into the world’s oldest ginkgo tree, you can clearly see the scorched part of the tree trunk that has been burnt to black. Due to natural factors such as lightning strikes, the ginkgo has formed a cavity about 3 meters in diameter in the trunk. There are layers of shells left. Although it has been hit so hard, the entire ginkgo tree still grows lush.

Even if it was struck by lightning in this place and lived for 5,000 years, it would feel the magic of life, and then it would feel that its vitality was relatively tenacious.

Its own factor is this tree species. It has a relatively strong adaptability. After this tree species is injured, it is more able to recover and has a relatively strong recovery ability. As long as the remaining part is able to recover, this is a reason for its longevity.
Of course, it is a long-lived tree species genetically. Why we see this tree species planted in many temples is because of its longevity, so this is its own reason.
Another reason must be the environmental conditions, that is, the soil, moisture, climate and other factors that we call the ecological environment. The light and these factors are able to meet the requirements of its growth to the greatest extent, so it must have a long life.
[Explanation] In addition to the self-healing ability of the ginkgo tree and the local climatic conditions, some hanging bumps on the shell of this broken ginkgo tree have become the most critical factor for its continued survival.
Yang Chenghua, a senior engineer at the Guizhou Academy of Forestry Sciences, told reporters that these nodules are called "aerial roots", which are adventitious roots that grow above the ground and are exposed to the air.
They grow roots in the reverse direction from the trunk, providing the possibility of regeneration for ginkgo.

It will produce this "Aerial Root", that is, it will heal faster, and then after this "Aerial Root" is produced, (Aerial Root) first absorbs water from the air and supplies it with the required water. If this "Aerial Root" continues When it finally reaches the ground, it will form a new root system from the ground down. That is to absorb the nutrients in the soil. This is the reason for its longevity and recovery.
[Explanation] Ginkgo is a plant of the Ginkgo family and the genus Ginkgo. It is a dioecious and special plant with the same sexual reproduction method as animals.
In addition to the ornamental and medicinal scientific research value of Ginkgo biloba, the largest and oldest ginkgo tree in the world currently plays a more important role.
[Concurrent] Yang Chenghua, Senior Engineer, Guizhou Academy of Forestry Sciences
In itself, it has broken through our general imagination, at least the life limit of this species. On this basis, this ancient tree plays an important role in studying the local climate environment, this geologically changing environment, and these.
For the survival of human beings, we explore some living environments, it must be meaningful, that is how do you find a good living environment.
This kind of research may have some impact on us now and in the future.
