The latest course of grafting techniques and methods of Osmanthus fragrans

Sweet-scented osmanthus is a kind of Oleaceae in China, sweet-scented osmanthus is mainly used for greening construction, followed by sweet-scented osmanthus can also be used for tea, wine, pastry and so on, has a certain edible value. Finally, the osmanthus twigs of some sweet-scented osmanthus flowers such as cinnamon and cinnamon are also commonly used in traditional Chinese medicine. At present, there are many planting methods for sweet-scented osmanthus trees, such as seed propagation, cutting propagation, striping propagation, and grafting propagation. Today, what the editor wants to share with you is the grafting propagation technology of sweet-scented osmanthus. Let's learn it together.

1. Rootstock selection

When using grafting to propagate sweet-scented osmanthus trees, the selection of rootstocks is very important. Not all rootstocks are suitable for grafting sweet-scented osmanthus trees, so we have to choose suitable rootstocks, such as privet trees, ash trees, fimbria trees, holly trees, water wax trees and so on. The selection of these rootstocks is more beneficial to the growth of sweet-scented osmanthus branches after grafting, and to a certain extent, although the growth cycle is shorter, enter the flowering stage earlier.

2. Scion selection

Scion is the choice of sweet-scented osmanthus branches, in general, we only need to choose sweet-scented osmanthus branches with no diseases and insect pests, more robust, pure varieties and more flowering varieties. Secondly, the sweet-scented osmanthus branches used for scion should be fully grown or two-year-old branches, so that the selected scion can heal more quickly with the rootstock and grow new branches.

3. Grafting method

Osmanthus osmanthus grafting also needs to choose the right time, usually in March to May and October each year, when the survival rate of grafting will be higher. When grafting, we need to choose the appropriate scion according to the thickness of the rootstock, and choose the appropriate grafting method, which is bud grafting, tongue grafting, bud grafting, splicing grafting, split grafting or hypodermic grafting. The thinner rootstocks can generally use one or two-year-old scions to do tongue grafting, cutting, embedded bud grafting and lean grafting; thinner rootstocks can use annual scions for bud grafting; finally, thicker rootstocks can be used for split grafting and subcutaneous grafting. When grafting, align the interface of the rootstock and scion, and wrap the interface tightly with plastic film or plastic film.

4. Management after grafting

In order to promote the healing ability of grafted seedlings, we need to check whether there is air leakage near the interface, so as not to affect the healing of rootstocks and scions. If we are using bud grafting, then we need to cut off some of the rootstocks on the interface and keep about one centimeter. If you rely on grafting, after the rootstock and scion are healed, cut off the bottom of the scion ring in time, and finally grow for another month or so, disconnect the mother plant from the scion and wipe off the new buds, and so on when new branches and leaves finally grow, then the bound plastic film can be untied.

The grafting technology of sweet-scented osmanthus trees is basically like this. in fact, the grafting methods of many seedlings are not much different, the most important thing is the selection of rootstocks and scions, the second is the correct grafting method, and finally the management technology is in place. in this way, the survival rate of grafting is very high. This is the end of what the editor is going to explain to you today. If you have anything else you want to know, you can leave a message for the editor.
