Ginkgo tree planting: how to graft ginkgo tree?

How are ginkgo trees grafted? Why are ginkgo trees grafted? What are the grafting methods? Please introduce the reasons for the grafting of ginkgo biloba trees: ginkgo biloba is a longevity tree, which not only grows slowly, but also blossoms and bears fruit very late. Generally, the tree begins to blossom and bear fruit after 20 years of age. However, if the grafting technique is adopted, it can blossom and bear fruit in 2-3 years. Detailed operation methods of ginkgo biloba grafting: 1. selection of ginkgo biloba grafting rootstocks: 2-3-year-old seedlings are suitable. Because of many branches and leaves of 2-year-old seedlings, developed roots and rich nutrient storage, the survival rate of grafting is high, and the general survival rate is more than 90%. 2. Selection of ginkgo biloba grafting scion: in the growing season, one-year-old branches were collected from 30-40-year-old fine variety trees as scions. Pick up as far as possible, need long-distance transportation should pay attention to moisturizing, prevent decay, conditional low temperature (3mur5 ℃) storage, can also seal wax moisturizing. Ginkgo biloba is a dioecious plant, so scions should be collected and stored according to different genders. 3. Grafting method of ginkgo biloba: grafting was carried out from late June to early August every year. When grafting, cut off from the new half-lignified part of the rootstock, cut a vertical mouth with a sharp knife in the middle of the cut, and the mouth is 2-3cm long. Under the scion bud 1cm, the cuttings were cut into a 2-3cm wedge, and then cut from the 1cm on the bud to form a single bud bilateral symmetrical wedge-shaped scion. The cut scion is quickly inserted into the cut of the rootstock, so that the smallest side of the two sides is aligned, and the plastic strip is used in time to tie tightly and tightly, so that the bud eyes are exposed. When possible, a plastic bag (caliber 3-4cm, length 10-15cm) can be placed above the scion to prevent a large amount of water evaporation and play a protective role. The best grafting time should be in cloudy days, low temperature and high relative humidity, but not in rainy days. After the grafting survived, the plastic bags should be removed in time. In addition, the female and male plants of grafted seedlings in the nursery should be distinguished. 4. Management of grafted Ginkgo biloba seedlings: the grafted seedlings can grow in the original seedling bed for one year, during which there should be large amount of fertilizer and water, foliar fertilization, timely ploughing and weeding, and speeding up the growth of seedlings. In the spring of the second year after grafting, it was transplanted and planted according to the row spacing of 30cm × 60cm. After 2 years, the seedlings between rows and plants can be carried out to facilitate the cultivation of large seedlings of different specifications. Seedling transplanting can be carried out before and after Frosts Descent. Click for more ginkgo tree planting techniques click to get more flower planting techniques
