How to graft sweet-scented osmanthus trees? Please guide the grafting of sweet-scented osmanthus, among which the grafting method is commonly used, which is often used in potted sweet-scented osmanthus in China. Its advantages are: long time for grafting, easy to survive, fast forming and early flowering. Now the key points of sweet-scented osmanthus grafting technology are introduced as follows: first, cultivate rootstock. The rootstock species used for grafting sweet-scented osmanthus include privet, tassel tree and so on. The rootstocks for grafting should be 2-3-year-old seedlings with a diameter of more than 1 cm or 2-3-year-old branches on perennial trees with robust growth, free from disease and insect pests. Second, choose scion. Osmanthus fragrans have Jin Gui, Yin Gui, Dan Gui, Siji Gui and other varieties. First of all, sweet-scented osmanthus varieties can be selected according to their preferences and resource conditions, and then 2-3-year-old branches with strong growth, full development, no diseases and insect pests and moderate size can be selected as scions. Third, grafting method. (1) move the scion close to the rootstock. The branches of sweet-scented osmanthus selected as scions can be close to the branches of rootstocks by means of support, cushion, frame, hanging, binding and so on. Then determine the suitable grafting position of rootstock and scion, and fix the position. (2) cut the bevel of the interface. The interface bevel was cut at the grafting site between the rootstock and the scion. The slope is oval in shape, with a length of 3 cm ~ 5 cm, and the depth of the slope is generally no more than half of the thickness of the branch. (3) cutting anvil. After the grafting and binding is completed, cut off the branches of the rootstock 1 cm above the interface. (4) removing cuteness. After grafting, if the branches germinate below the interface of the rootstock, it should be erased in time. From 31 to 35 days after grafting, the scion was cut off from the interface and separated from the mother. (5) Survival check. From 3 to 5 days after cutting grafting, the scion branches and leaves grow normally and survive; if the leaves wilt and curl, that is, they do not survive, they should be re-grafted. After the grafting survived, the branches grow fast, and the binding rope is easy to be embedded in the bark to affect the growth, so the binding rope should be loosened in time.
