Propagation methods of Ginkgo biloba

Ginkgo is a tall tree of the ginkgo family, and its seeds are commonly known as ginkgo, which is a kind of green health food, so ginkgo trees are multiplied in large numbers as cash crops. Today, the editor will introduce the breeding methods of ginkgo trees.

1. Cutting

Cutting is cutting branches from ginkgo trees that have been growing for many years and inserting them into the soil to make the branches take root and sprout in the soil to form a new tree. Cutting is divided into old wood cutting and tender wood cutting. most of the old wood cutting is used to cultivate a large number of trees for a variety of commercial purposes, while the tender wood is used for family personal planting, and we can choose according to our own conditions. Old wood cutting is suitable for spring. Choose the branches that grow well on the big tree and cut them into cuttings of about 20 centimeters. After cutting, rinse them with water and soak them with rooting powder, then insert them into the soil, which will take root and sprout for about a month, and then carry out normal maintenance and management. tender wood cutting is to cut the twigs into the container and change water every 3 days until they grow roots and then move into the soil.

2. Ramet

Ramet propagation is generally used to cultivate the needs of urban greening, because there are more cases of ginkgo trees sprouting, especially trees about 15 years old, the method is to clean up the soil around the roots of the trees, cut the tillers off from the trees with sharper ones, and then plant them in other places for cultivation and management. this method can generally bear fruit earlier.

3. Grafting

Grafting is generally used to produce ginkgo fruits in large quantities, and the grafting time is generally in summer, but it should be noted that grafting can not be carried out at very high temperature, especially at noon, not even on rainy days. The main method is to cut off a leaf on a well-developed branch, leaving only the petiole, wrapping the cut leaves in wet cloth or putting them in water, and it is most appropriate to choose cuttings as grafting objects. After grafting, it is necessary to seal the interface with plastic film and other film cloth, and then carry out normal maintenance and management, which will generally result in 6-7 years.

4. Sowing seeds

Sowing is mainly used for the construction of greening and bonsai. In autumn, the seed is harvested, the seed skin is removed, the seed is dried, and the seed is sown in winter or spring. When sowing, the seed should be placed in a dug ditch or hole with a depth of 3-4 cm. Cover it with soil and trample the soil thickly. After a year, the saplings can grow to about 30 cm, and they can begin to transplant, but the drainage system of the sowing land should be good and can not produce stagnant water. Otherwise, the saplings will be rotten.
