Embodiment Construction

[0011] Below in conjunction with embodiment the present invention will be further described.

[0012] A kind of grafting propagation technique of American red leaf crape myrtle, comprises the following steps:

[0013] 1) Select the rootstock: the grafting time is from late May to early June every year, and choose dwarf crape myrtle with a ground diameter of 1 to 3 cm in 1 to 2 years and a well-growing main branch as the root stock;

[0014] 2) Clipping the scion: Select the semi-lignified branches of the American red leaf crape myrtle that are well developed and full of axillary buds, and avoid high temperature and rainy weather. Branches should be harvested and harvested at any time, and those that cannot be completed on the same day should be refrigerated;

[0015] 3) The scion is combined with the rootstock: at a place where the rootstock is about 15 cm above the ground, cut off the branches that are roughly the same diameter as the scion or slightly thicker in step (2), a...
