How to cut crape myrtle? Technological process

The cutting propagation steps of Lagerstroemia indica are as follows:

1, choice of nursery

Sandy soil with deep soil layer, loose soil and leeward is used as nursery land or calcareous soil rich in humus. The width of the nursery is 1.2m, and the length of the nursery varies according to the site. There are 40-50 cm wide paths between nurseries, and drainage ditches are dug. Disinfect the soil before cutting.

2. Cutting treatment

There are two kinds of cuttings of Lagerstroemia indica: hard cuttings and soft cuttings. Hardwood cutting should be carried out from late March to early April. Softwood cuttings are mostly in the first half of June in summer, and they are inserted as soon as they are picked. Cuttings should be annual robust, completely lignified and free from pests and diseases, and hard cuttings in spring should be stored in winter.

Step 3 cut

In order to improve the survival rate of cuttings, cuttings should be soaked in running water 6-8 days before cutting. 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.

4. 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.

Lagerstroemia speciosa likes warm and humid climate, light, a little shade tolerance, fat, especially the deep and fertile sandy loam. It is suitable for being born in a slightly humid place and is also resistant to drought and waterlogging. It is forbidden to plant in places with high groundwater level and low humidity. It is warm, but cold-resistant and has strong germination.

Lagerstroemia indica also has strong anti-pollution ability and strong resistance to sulfur dioxide, hydrogen fluoride and chlorine. ? Semi-shady, like to be born in fertile and humid soil, but also drought-tolerant, calcareous soil and acidic soil grow well.

China, Guangdong, Guangxi, Hunan, Fujian, Jiangxi, Zhejiang, Jiangsu, Hubei, Henan, Hebei, Shandong, Anhui, Shaanxi, Sichuan, Yunnan, Guizhou and Jilin are all planted or cultivated. They are native to Asia and widely cultivated in tropical areas.
