How do ginkgo trees reproduce?

Ginkgo tree, also known as ginkgo tree, is a rare tree species of Mesozoic era, known as "living fossil". It has high medicinal and ornamental value. Nowadays, wild ginkgo trees only exist in Tianmu Mountain, Zhejiang Province. So how do ginkgo trees reproduce?

I. Propagation techniques of Ginkgo biloba

There are three propagation methods of ginkgo biloba: cutting, splitting and sowing, in which cutting propagation can be divided into old branch cutting and tender branch cutting; split propagation is cultivated by tillering seedlings from the rhizosphere of the mother plant of Ginkgo biloba; sowing propagation is to propagate with the seeds of Ginkgo biloba, which is usually sown in the first and middle of March.

Cutting propagation can be divided into two types: old branch cutting and tender branch cutting. Old branch cuttings are suitable for large growers, while tender branch cuttings are suitable for general families and small units. The general method is to select strong branches, cut them into cuttings 20 to 25 centimeters long, cut diagonally at the bottom, and then insert them into the soil and water after 1 hour in rooting powder water. The best cutting time is before the plant sprouts in spring, and the survival rate can reach 80%.

Ramet propagation is generally selected for 2 ~ 3 years old in spring, separated from the mother plant with roots and planted separately. It can be cultivated in the nursery for 1 year, or it can be planted directly. The method is to clean the soil around the roots of the tree, use a sharp one to cut the tiller from the tree, and then plant it in other places for cultivation and management. this method can generally bear fruit earlier.

Sowing and reproduction involves peeling the seeds harvested in autumn, drying them in the sun, and sowing them in winter or spring. When sowing, put the seeds in a dug ditch or hole with a depth of 3-4 cm, cover it with soil, step on the soil thickly and firmly, and the saplings can grow to about 30 cm after a year, and you can begin to transplant.

II. The main value of Ginkgo biloba

The value of Ginkgo biloba is mainly reflected in medicinal and ornamental aspects. The fruits and leaves of ginkgo biloba can be used as medicine, and their fruits can also be eaten, but eating too much can easily lead to poisoning.

Ginkgo biloba extract has obvious effect on the treatment of coronary heart disease, angina pectoris and hyperlipidemia, besides ginkgo biloba has the effects of anti-hypoxia, anti-fatigue and anti-aging.

Ginkgo biloba has a beautiful tree shape and vigorous physique, with bright green leaves in spring and summer and golden yellow in autumn, which is very beautiful and generous. as a street tree, the golden leaves are numerous and full of autumn. Wang Wei, a poet of the Tang Dynasty, wrote a poem praising: "Ginkgo biloba is planted as a beam, citronella is a Yu, and I don't know the clouds in the east, so I go to live in the rain."

The above is some relevant knowledge about Ginkgo biloba. Every year, the autumn yellow season of Ginkgo biloba attracts a large number of tourists to the areas where ginkgo biloba is planted. "one night cold Frosts Descent, ginkgo yellow all over the city", the beauty of the Golden Avenue all over the city is also very moving.
