Propagation method of ginkgo tree 1
For ginkgo trees, the simplest propagation method is cutting propagation. Select robust branches from ginkgo trees, preferably about 0.5 ~ 2 cm in diameter, and then cut them into 20 ~ 30 cm long. Soak the lower ends of branches in rooting solution 1 ~ 2 days, then cut them into the soil, and then water them until they take root.
2, sowing and breeding
On how to breed ginkgo trees, you can also choose to sow and breed. Ginkgo seeds collected in autumn are soaked in clear water to accelerate germination. Then sow the seeds with small germs into the soil, cover them with 3-4 cm soil, compact them, and water them to soak the soil. Generally, seedlings can emerge in about half a month.
3, ramet propagation
In fact, ginkgo trees with more buds are also propagated by individual plants, but this is mainly for ginkgo trees with 10 ~ 20 years old. Clean up the soil around the roots of ginkgo trees in spring, then cut off the tillers and pay attention to the fibrous roots on them, then treat the wounds, dry them and cultivate them in the soil.
4. Grafting propagation
Ginkgo trees can also be grafted and propagated from May to August every year, but it should be noted that grafting is not allowed in hot and rainy days, and it should be avoided at noon on sunny days. Select a suitable cutting, cut it, keep 2 ~ 3 buds and 1 ~ 2 petioles on it, then soak its lower end in water, and then graft it on the prepared 2 ~ 3-year-old rootstock. After aligning the incision, tie it tightly with film, and then water it for maintenance, and the grafting is successful.
