Huxiang's natural calendar 丨 Jinghong glance ⑱ A very calm tree

On Monday, September 19, 2022

After many changes in sea, land, glaciers, and cold and cold, there are very few plants that can survive from ancient times, and people are used to calling them live fossils. In China, the famous living fossils include Shuikou, Silver Shan, Ginkgo, etc.

In recent years, a tall tree has been discovered in Mangshan, Hunan, and was called a horseshoe because of his seed -cut surface like horseshoe. Studies have found that horseshoe is also a kind of living fossil plant, which is very similar to a fossil plant in the Chinese and Sino -Singaporean stories in Europe.

Horseshoe has been included in the "Red List of Endangered Species of the World Nature Conservation Alliance", which is a near -dangerous plant. People try their best to cultivate, but the horseshoe is not concerned, and the seed production is very low. Attentive people will find that although the flower stems of horseshoe bloom a lot, they are very small.

Even if the seeds are born, the germination rate is very low. The seeds of horseshoe have the characteristics of dormancy. They can only germinate for two years, and during the dormant process, animals will eat and rot. The germination rate is only about 10%. Even if the seedlings are smoothly germinated, the growth of seedlings is very slow and the survival rate is low.

Even if it grows into a saplings, the horseshoe is sinking than the plants around. 10 years of horseshoe ginseng diameter is only about 5 cm; 30 years of chest diameter is about 18 cm and the tree is 6 meters high; in 130 years, it can become a tall tree with a diameter of about 45 cm and about 20 meters high.
