1. Cutting planting: Cut branches from the old ginkgo tree and insert them into the soil, so that the branches can take root and sprout in the soil to form a new tree. Cuttings are suitable for growth in spring and are better for growing on big trees. Cut the good branches into cuttings of about 20 cm. After cutting, rinse them with water and soak them in ABT rooting powder. Then insert it into the soil and it will take root and sprout in about a month. Then carry out normal maintenance and management.

2. Division planting: Division propagation is generally used to cultivate urban greening, because ginkgo trees tend to sprout more often, especially trees that are about 15 years old. The method is to clean the soil around the roots of the trees, use a sharp tool to cut off the tillers from the trees, and then plant them in other places for cultivation and management. This method can generally lead to early fruiting.

3. Grafting and planting: It is generally used to produce ginkgo fruits in large quantities. The general grafting time is in the morning and evening on sunny days in summer. The main method is to cut off a leaf on a well-developed branch, leaving only the petiole. , wrap the interface of the cut leaves with wet cloth or put them into water. It is best to choose cutting seedlings as grafting objects. After grafting, seal the interface with plastic wrap and other film cloth, and then carry out normal maintenance and management. Generally, after 6 -It will bear fruit in 7 years.

4. Sowing and planting: Sowing is mainly used to build greening and bonsai. Harvest the seeds in the fall, remove the seed coats, dry the seeds, and sow them in winter or spring. When sowing, the seeds should be placed in a dug trench or hole with a depth of 3-4 cm, covered with soil, and the soil should be stepped on thickly. After one year, the saplings can grow to about 30 cm, and transplantation can begin. However, the drainage system of the sowing land must be good, and there should be no accumulation of water, otherwise the saplings will rot.
