Throughout the long history of the planet, some tree species have been hailed as "living fossils" due to their unique survival and evolutionary processes. These tree species have endured millions of years of wind and rain, witnessed the changes of the earth, and become witnesses of history. Among them, the ginkgo tree is widely regarded as a representative of living fossils because of its unique characteristics and historical background.
1. The origin and distribution of ginkgo
Ginkgo, known as the duck's foot tree or Gongsun tree in ancient times, is a species of the genus Ginkgo biloba in the family Ginkgoaceae. More than 270 million years ago, the ancestors of ginkgo biloba appeared and became one of the higher plants at that time. With the change of geology and climate, most of the ginkgo plants have become extinct and have only been preserved in some parts of China. As a result, Ginkgo biloba is a rare treasure and is regarded as a living fossil of the plant kingdom.
2. The characteristics and value of ginkgo
Ginkgo biloba is a long-lived tree species that can live up to a thousand years. It has a long growth cycle and takes about 20 years to flower and bear fruit. Ginkgo biloba blooms in April every year, but due to its long lifespan, many people may not be able to see it bloom in their lifetime. If the conditions are right, ginkgo biloba will bloom and bear fruit. The round fruit of ginkgo biloba, known as ginkgo seed, is a traditional Chinese medicinal material with high nutritional value and medicinal value.
3. The cultural significance of ginkgo
Ginkgo biloba is not only a precious plant, but also carries a rich cultural connotation. In traditional Chinese culture, ginkgo symbolizes tenacity, composure, and pure feelings. Its flowers and fruits are seen as a symbol of auspiciousness and harmony. Therefore, ginkgo biloba is used as a landscape tree or street tree on many occasions and has become an important part of urban greening.
Fourth, the cultivation and protection of ginkgo
Since Ginkgo biloba is a precious living fossil tree species, its protection and cultivation are particularly important. Currently, many ginkgo trees are grafted and can bear fruit in a relatively short period of time. At the same time, in order to protect the naturally growing ginkgo tree community, relevant institutions have taken a series of measures, such as establishing nature reserves and promoting planting. Through these measures, we are better able to protect and utilize this precious living fossil resource.
5. Summary
As a representative of living fossil tree species, Ginkgo biloba not only has unique biological characteristics and value, but also carries rich cultural connotations. Through the study and conservation of ginkgo, we can better understand the history and evolution of the earth, while providing an example of human harmony with nature.
