Cultivation method of Lagerstroemia indica

1, ground planting: 1 1 After defoliation, planting in March of the following year. When planting, leave the trunk 100~ 130 cm high and cut off the upper part. After the new spring bamboo shoots grow, choose 3~4 main branches with suitable angles and let them blossom.

2. Potting: Using the seedlings of old branches in the past is a good way to quickly cultivate bonsai. Because the branches of Lagerstroemia indica are soft, potted Lagerstroemia indica can be properly climbed and bound. Generally, when the spring shoots stop growing and the branches tend to be semi-lignified, they are coiled and drawn with thin brown ropes to make bonsai in various postures. Low-grade trees for roads or gardens

As far as greening function is concerned, Lagerstroemia indica is a single tree species used as street trees. There are even fewer characteristic tree species such as Lagerstroemia indica, which not only meets the basic requirements of street trees for shading, dust retention, noise reduction and absorption of toxic gases, but also has beautiful tree posture and gorgeous colors. Therefore, Lagerstroemia indica as a street tree will have a broad market for technical development and promotion (there have been successful cases of small street trees in the United States). However, street trees have certain requirements for trunk height (generally, the lowest branch height is more than 2.0m above the ground), while Lagerstroemia indica usually has low branching points, strong lateral bud germination and relatively weak trunk polarity, so the technical difficulty to be solved as a street tree is to cultivate trunk. The author recommends the following three methods to solve this problem: a. Short cutting off strong buds or changing heads; B. dry cutting method; C. repeatedly cut short the side branches to promote the central trunk.

Garden solitary tree

The single planting of trees is mainly to show the physical beauty of trees, and can be independently landscaped for viewing. As an exclusive tree species, it is generally required to have a beautiful tree shape, a tall or strange trunk shape and a long life. The biggest advantage of Lagerstroemia indica as an ornamental tree species lies in its stretched posture, lush foliage and lush flowers; However, the main problem is how to achieve the "Qiao Hua", which needs to work hard on the stem shape and crown shape to fully reflect its ornamental value.

Landscape tree

The landscape trees we are talking about here have a wide meaning: they refer to all garden trees that are applied to roadsides, pools, mounds, corridors, front and back houses, or matched with rock buildings, or scattered in groups of 30 to 50 trees in some small scenic spots, thus forming a natural and interesting layout. Most of them have unique ornamental characteristics in branches, flowers, fruits, leaf color or leaf shape, which can be well coordinated with the surrounding environment in garden application and create beautiful scenery. When Lagerstroemia indica is used as a landscape tree, we should fully consider the differences of application places in order to choose different styles to match it. Here we recommend several kinds, such as cup-shaped, happy-shaped, cluster-shaped, combined group plants, pavilions, vases, flower baskets, archways, animals and even geometric shapes.

Bonsai modeling tree

Bonsai is not only a potted plant confined to indoor viewing, but also applied to parks, botanical gardens, squares and even residential areas for various sketches. Lagerstroemia indica has been a very good bonsai tree material since ancient times, and it is one of the "eighteen bachelors" in pile scenery; Among the eight traditional schools of pile scenery, Huizhou School and Sichuan School are widely used. To sum up, it has various shapes, such as bending, cross-bending, bending-dry, dry-type, twisting-type, screen-type and Youlong-type. Therefore, another important garden landscape use of Lagerstroemia indica can also be equipped with various pile landscape shapes in a suitable environment to achieve a rich, simple, elegant and finishing touch effect. Lagerstroemia indica has strong anti-pollution ability and can resist toxic gases such as sulfur dioxide, hydrogen fluoride and chlorine, so it is also an ideal flower for beautifying the environment in industrial and mining areas and residential areas. Li Shizhen also recorded in Compendium of Materia Medica that the bark, wood, flowers, seeds and leaves of Lagerstroemia indica can be used as medicine. The roots, leaves and skins of Lagerstroemia indica have the effects of clearing away heat and toxic materials, promoting blood circulation and stopping bleeding.
