Lagerstroemia indica; Grafting time; Grafting method

It is best to graft Lagerstroemia indica in the middle of March-April, when its bud just germinates, or in August-65438+10 of that year. At this time, Lagerstroemia indica is in the growth period, and the grafting survival rate is high.

Lagerstroemia indica grafting method

Bud grafting: when Lagerstroemia indica bud grafting, cut a knife vertically from top to bottom, and then cut a knife at a 30-degree angle from bottom to top. Select buds from scions, cut them, cut them into shield shapes, and stick them to form a layer. Tie it from bottom to top and wait for germination. Cleavage: Cleavage Lagerstroemia indica in early February-March, select stout seedlings and insert them directly from the peripheral tree core, then take scions with 2-3 buds, cut them into wedges, put them at the cleavage place where rootstocks are inserted outside, and wrap them with plastic film.

Matters needing attention in grafting Lagerstroemia indica

Fixation: Lagerstroemia indica fixes the grafted rootstock on the branches of Lagerstroemia indica without displacement. It can graft multiple rootstocks on each branch, which can improve the grafting survival rate. Healing agents or wooden sticks can be used to fix the intra-marital joints, wrap them tightly and fix the residual limbs to prevent shaking. Maintenance: After grafting, in the initial stage of maintenance, it is best to spray water on branches three times a day to reduce water evaporation and keep the substrate moist and breathable. When the temperature rises in summer, shade in time and increase watering. Fertilization is not suitable for curing period.
