Ginkgo autumn grafting

Grafting time in the fall autumn season Ginkgo biloba from mid-August to mid-September is appropriate, specific time around the country can be flexible according to different climates. Scion selection should be based on the local Ginkgo biloba species that have begun to produce results, collected at the time the shoots stop growing and the shoots are lignified. Scion scissoring should be a well-developed freshman year. To prevent the scion from losing water, remove the leaves immediately after cutting. If budding is used, leave the petiole when removing the leaf; if using the grafting method, leave no petiole. The branches are best grafted with the harvest. When grafting in the field, it should be placed in a washbasin or cask with a little water and covered with a damp cloth to follow. Grafting methods Ginkgo biloba autumn joints are mainly used splicing or tongue connection. The level of anvil cut off by the wall connection method should be determined according to the length of the scion, and the height of the rootstock that is generally retained is 2 times the length of the scion. Scions can leave 3 - 4 buds. A knife is used to cut a knife in the middle of the rootstock. The depth is determined by the thickness of the scion, and the thickness is shallow and shallow. At the lower end of the scion, each knife is cut to make it into a wedge shape. The wooden layer in the middle of two noodles should be slightly thicker and one side slightly thinner. The noodles should be smooth and smooth. Then the scion is inserted from the rootstock rind, so that the rootstock closely matches the formation layer of the scion, and finally tied with a tie material. The length of the scion and the height of the cut stock were the same as those of the splicing method. The diameter of the rootstock and scion should be equal, if not equal, the diameter of the scion should be smaller than the diameter of the rootstock. Cut 3cm to 4cm long bevels from the scion and rootstock, and cut 1cm to 2cm from the inclined surface at 2/3 to make them tongue-shaped and embed each other. If the thickness of the scion and rootstock is the same, both sides form a layer. Alignment, such as a bit thicker rootstock, can be aligned, and finally banding. After the management, the temperature of grafting in autumn is higher. As long as suitable humidity is maintained, management measures such as weeding and fertilization can be performed in time, the interface can be quickly healed, and scions can sprout. But after the buds in the spring of the following year, they can be untied. China Agricultural Network Editor
