What tree species are used for grafting Lagerstroemia indica?

There are several varieties of Lagerstroemia indica, such as Yin Wei, whose flowers are white; Cuiwei, the flowers are blue-purple and lavender; Red, pink, crimson, etc. ; The author grafted several annual or biennial branches with different colors on the same tree, and the survival rate was over 98%. The specific method is: from late February to early March, before the branches of Lagerstroemia indica sprout. When grafting, the well-developed seedlings are selected as rootstocks, and the branches of the required color are used as scions, and the splitting method is adopted. First, the top of the rootstock near the peripheral part is split longitudinally with a knife about 5-8 cm deep, and then the scions of more than two buds with a length of 5-8 cm are cut into wedges and inserted into the split part of the rootstock to align with the cambium. Then wrap the whole spike with plastic film to expose the bud head. This method is used to graft branches of different colors on the same rootstock in layers to form multi-color trees. After 2-3 months of grafting, the membrane can be loosened. At this time, the length of the ear head can reach 50-80 cm. Branches should be cut short in time to avoid being broken by the wind and can be cultivated into thick branches. The survival rate of plants cultivated in this way is very good. crape myrtle

Specific practice: from late February to early March, before the branches of Lagerstroemia indica germinate. When grafting, the well-developed seedlings are selected as rootstocks, and the branches of the required color are used as scions, and the splitting method is adopted. First, chop a knife at the top of the rhizome near the peripheral part, about 5? 8 cm deep, and then take the length of 5? 8 cm scions with more than 2 buds were cut into wedges and inserted into the cracks of rootstock, aligned with the cambium. Then wrap the whole spike with plastic film to expose the bud head. This method is used to graft branches of different colors on the same rootstock in layers to form multi-color trees. Grafting 2? After 3 months, the membrane can be loosened and the length of the ear head can reach 50? 80 cm, the branches should be cut short in time to avoid being broken by the wind, and can be cultivated into thick branches. The survival rate of plants cultivated in this way is very good. The author summed up the following conclusions from years of practice: among the five propagation methods, the color of seedlings cultivated by the latter four methods maintained the excellent performance of scions. However, there are many buds and branches produced by plant cutting and division, which need to be removed in time. If you need to practice to become a senior 3? For 6-meter trees, the seedlings propagated by sowing method are better, and the side branches produced are obviously reduced, but the colors of seedlings propagated by sowing method are easy to vary.
