Bright, long flowering period, it is an important ornamental flower in summer. Widely used in street greening and garden layout, it is a good tree species for garden greening.

Before cutting, you can put some rooting powder on the bottom of branches. Lagerstroemia indica has low requirements on soil. Cutting soil can be clean river sand, and branches can be inserted into one third of the soil during cutting. After cutting, it is best to put the branches in a ventilated and semi-cool environment for propagation, and water the plants in time during the propagation process.

Lagerstroemia indica grows fast, and its branches can take root in 20 days. When the branches are half a man's height, they can be planted in the soil. The transplanted soil can be mixed with humus soil, garden soil and river sand. Lagerstroemia indica likes to grow in a warm and humid environment, and has high requirements for light. When planting, plants should receive sufficient light.

Cutting propagation method

In order to improve the survival rate of cuttings, 6? The cuttings should be soaked in running water for 8 days. If it is stagnant water, it must be changed every day. When the lower incision appears obviously irregular tumor, it is cut. It can also be soaked in 1% sucrose solution for 24 hours, which can significantly improve the survival rate. Carefully prepare the soil before cutting and apply sufficient base fertilizer to make the soil loose and full of water. First, drill a hole with a tool, insert cuttings along the hole, and then seal the hole tightly. The cutting depth is 2/3 of the cutting length, the plant spacing is10cm, and the row spacing is15cm. After the cuttings are inserted, pour water.

Post-insertion management

After cutting, cover the seedbed with plastic film, seal it with soil, and shade it with sunshade net. It usually takes about three weeks to take root and sprout. After the cuttings take root, the mulch is removed step by step. After cutting, the seedbed should be kept moist, and watered with small water and clear water at seedling stage to make it penetrate the seedbed and avoid flooding. Irrigation 1 time every 3 ~ 5 days. Quick-acting fertilizer should be applied after 40 days of cutting, and the principle of fertilization by stages should be mastered. Regularly weed and loosen the soil artificially. Small seedlings should be shallow and big seedlings should be deep. Generally, the depth of loosening soil is 2 to 4 cm, and then it is increased to 8 to 10 cm. Lagerstroemia indica leaves are often infected with powdery mildew and sooty blotch. 5 Baume sulfur mixture or spraying 70% thiophanate-methyl wettable powder 800 during the growth period? 1000 times solution, 25% triadimefon 800 times solution.
