first, the main planting significance of landscaping tree species.
Purifying air
Most of the time, when designing sapling varieties, it will mainly consider its purifying effect on the ambient air. For example, planting varieties such as Lagerstroemia indica, Pu Shu, Pistacia chinensis, etc. is beneficial to our environmental purification, especially when the urban traffic volume is large and the air and exhaust gas are affected, which can purify the air. Plants on both sides of the road mainly consider its adsorption of ash layers. Magnolia grandiflora is very good, and its leaves can adsorb most of the ash layers in the air.
Visual color matching
Color matching will also be taken into account when planting landscaping tree species, which can add a lot of colors and vitality to our lives, especially the colorful plants such as park greening and square greening, which are well matched. Perennial flower bonsai is commonly used, and most varieties are cultivated in greenhouses, which can basically reach the state of full flowers before leaving the garden, and the beautification effect is better.
II. Subdivision of common landscaping tree species
Arbor
Arbor trees can be subdivided into Da Qiao: Pu Shu, Cinnamomum camphora, Ginkgo biloba, Sophora japonica, Pistacia chinensis and Sapindus mukoraiensis. These trees belong to the category with relatively large total volume and height, and are old. Most of the large-scale Da Qiao trees are cultivated mature seedlings, and they have a high survival rate after being transplanted again. There are some flowering trees in Er Qiao, whose total volume and height are medium, and most of them can survive with native seedlings. The varieties are Magnolia grandiflora, Osmanthus fragrans, Lagerstroemia indica, Magnolia grandiflora, Cherry Blossom, Sapindus mukoraiensis, Nanmu, Tenjikukatsura, Begonia pendula and Michelia Lechang, including flowering varieties, evergreen trees and deciduous families. There are hundreds of varieties in Er Qiao, so I won't introduce them all here.
modeling ball games
when most colored-leaf shrubs grow up, we will trim and shape their whole tree shape. Among them, there are many ball shapes, and most colored-leaf modeling ball games are cultivated by pruning from small seedlings. Those whose crown exceeds 2cm need to be cultivated continuously for more than 3 years. Commonly used varieties are: sweet-scented osmanthus ball, photinia rubra ball, Ligustrum microphyllum ball, photinia rubra ball and safflower following wood ball.
bamboos
This kind of landscape bamboo is only used in parks and squares. Compared with the trees and ball plants in front, the amount of bamboo used every year is relatively small, and many communities will plant it, but they are very few. The common varieties are: Qin Si bamboo, which is mostly used in larger parks, and black bamboo, purple bamboo, phoenix bamboo, golden bamboo, arhat bamboo, etc., and the planting range of this kind of bamboo is relatively small.
Shrub seedlings
Basically, in addition to planting only trees on roads that do not need color matching, some roads will plant more colorful plants, such as squares, parks, residential areas, villas and other areas, which are mainly used for hierarchical matching planting in relatively low planting areas. It is characterized by dense branches and leaves, short whole plants and bright colors of leaves. Commonly used varieties are: Ligustrum lucidum, Ligustrum lucidum, Photinia rubra, Anthurium rubrum, Cinnamomum cassia, Mahonia fortunei, Clever Flower, Melaleuca japonica, Illicium verum, Podophyllum, and so on. There are also hundreds of commonly used shrub seedlings, including red leaves, yellow leaves, golden yellow, green and so on.
flowers and lawns
In fact, these two kinds of flowers do not belong to landscaping tree species, but only belong to flowering plants and herbaceous flowers, and the colors and patterns of each kind of flowers are not needed. The seasonal flowers are also different from those of previous years, especially those cultivated in batches in greenhouses. Most varieties can reproduce in four seasons and bring flowers out of the garden. Commonly used varieties are: cuckoo, chrysanthemum, a bunch of red flowers and newspaper. There are relatively few varieties of herbaceous lawns, which can be divided into evergreen and semi-evergreen varieties, including Taiwan Province No.2, mixed lawn, horseshoe, slender lawn, Bermuda, Manila, Prunus mume, Japanese knot and other varieties.
