Ginkgo biloba is a living fossil of the plant kingdom, and the earth had ginkgo about 300 million years ago. Later, angiosperms appeared, competition and environmental changes and ginkgo biloba became less and less. Until the fourth season of the glacial movement, most of the ginkgo went extinct. Only in North China, East China, and Central China, because of the cold climate is not greatly affected, the mild climate has preserved this precious ancient plant.
He has certain scientific research results in the study of gymnosperms, ancient plants, paleogeography and glacial climate in the fourth century.
China is the origin of ginkgo, only the Shennongjia Nature Reserve in the world, and the deep valley on the border of Henan and Anhui has a small number of wild or semi-wild ginkgo remains.
I once saw a 995-year-old ginkgo tree in a nature conservation ecological village in Anhui Province.
Wild ginkgo biloba is now listed as a first-class protected plant.
Other areas are cultivated, Hunan, Shenyang, Guangzhou, Guizhou, Yunnan Tengchong have hundreds or thousands of years of old trees.
In the ancient Guanyin Temple in Chang'an District, Tang Taizong Li Shimin hand-planted ginkgo more than 1400 years ago.
Netizens said that Qianzhang Ginkgo is still there today, and I don't see the tree planters back then.
Korea, Japan, Europe and the United States are all cultivated.

Under the fallen leaves of the city,
Ginkgo never lives up to autumn.
Another year of fallen leaves,
Qingqiu is safe and sound.
The flowers are bulbous, dioecious , unisexual, clustered, and internally pollinated.
Seeds, often oval, oval, 2.5~3.5cm long, about 2cm in diameter, divided into outer, middle and inner three skins. Fleshy outer seed coat, yellow or yellow-orange when cooked, smelly of feces.
Small animals such as squirrels, civets and other small animals especially like to eat its seeds.
Ginkgo trees are divided into male and female trees, heterophytes. The leaves are deeply fissured, the large ones are male, the crown is rounded, it does not bear fruit. The leaf lobes are shallow, the small physique is female, the crown is pagoda-shaped, it bears fruit.
The propagation of ginkgo biloba has seeds, cuttings, grafting, ridge splitting, etc. Planting is best carried out from late October to early November, young branch cuttings in summer, and old branch cuttings in March~April. Choose loose soil, fertile soil, like moist, but drainage should be good, do not accumulate water.
Ginkgo grows slowly, but has an extremely long life, and is the old birthday star among trees. Because of its graceful posture, clustered fan-shaped leaves, tender green leaves in early spring, deep blue in midsummer, and golden in autumn, it is a typical autumn leaf species.
Together with cedar, money pine and araucaria, it is ranked as the "world's four largest garden tree species". Together with peonies and orchids, it is known as the "Three Treasures of Chinese Gardens".
It is very ornamental and economical.
Ginkgo biloba is also a Chinese medicinal herb. The leaves, fruits, and bark are all Chinese medicines. Li Shizhen's "Compendium of Materia Medica" records that "ginkgo, thin and thick taste, astringent and reaping, beneficial lung qi, fixed cough, reduce stool", and can kill insects and disinfect, was included in the "Chinese Pharmacopoeia".
Remarks: Although ginkgo biloba is a Chinese medicinal herb, we ordinary people do not understand pharmacology, and should be prescribed by a doctor, not blindly used. It backfired.
On the 18th, the Qianjiang Evening News reported that a Hangzhou aunt ate a pound of white fruit, nausea, vomiting, convulsions, and was admitted to the ICU.
Ginkgo biloba, also known as white fruit, is a dry, ripe seed of the Ginkgo family's Ginkgo family. This fruit contains ginkgolic acid, which contains up to 200 mg. Gloves should be worn when picking up, otherwise there will be contact dermatitis and corrosion of the skin of the hands.
Uncooked white fruits have ginkgo poison, which is converted into hydrocyanic acid in the human body, which is very harmful to the human body.
Do not eat more after processing. In a day, adults should be under ten, children under five, children under three years old should not eat, and the seed coat and germ are peeled when eating.

Ginkgo biloba is in the folk, some people like to use it to soak in water, and it is also dangerous. There is ginkgolic acid in it, which is also toxic.
Because of its long life, ginkgo has an extremely long life and has experienced vicissitudes. The meaning is tenacity and composure, and the flower language is innocence, representing eternal love. Giving it to the elderly has a beautiful meaning of prolonging life. Sandwiched in the book to send lovers, representing eternal love, in the long years, with my company.
Gone to Gu Ma Xiaosheng, I saw the young man Lang back then.
Isn't it? Wait for the flowers to bloom, wait for the leaves to fall, and finally return!
