What is the difference between native Lagerstroemia indica and grafted Lagerstroemia indica?

Grafting methods include cutting (cutting part) and budding (trunk part). Cutting is carried out in early spring, when the buds have not germinated, but the juice has begun to flow out. The method is to cut off the upper part horizontally, and cut about 3 cm longitudinally on one side, with a little xylem to expose the cambium; Cut one end of the scion into an oblique shape of about 2 cm, obliquely cut a knife on the back of the scion, insert the rootstock, align with the cambium, and then tie it. Bud grafting is carried out in the growing season, and T-bud grafting is commonly used. Select the plump lateral buds in the middle, cut off the leaves, keep the petiole, and cut them into buds with the cortex of the branches, which are about 2 cm long and slightly woody. Then cut the bark of the rootstock into a T-shape, pick up the cortex with a bud grafting knife, insert the bud, and tie it tightly with plastic film tape to expose the bud and petiole. Take off the plastic belt in time after survival. After grafting, seal the grafting site with wet yellow mud, and then cover the grafting site with a layer of moisturizing cover with plastic film to form a small environment with stable temperature and humidity to promote germination as soon as possible.
