People in China's agricultural products industry usually use Artemisia annua, Artemisia annua and Artemisia annua as rootstocks with developed rhizomes and vigorous growth, and use chrysanthemum seedlings to be propagated as scions for grafting. The splitting method is as follows: firstly, select the rootstock and scion, and then cut off the rootstock according to the required height, with a flat section and longitudinal cut on the section; Cut a knife on both sides of the lower part of the scion to make the scion wedge-shaped and insert it into the longitudinal incision of the rootstock. However, care must be taken to align the scion with the lateral cambium of the rootstock. The key to the success of the split is to do this and then tie it. Generally, one plant can graft 1-6 or 8 scions, depending on the thickness of the rootstock. After grafting, shade properly to prevent scion from withering and failure. After the scion survives and the incision is completely healed, the binding band can be removed and the small branches and leaves growing on the rootstock can be erased.
