Selection principles Common highway greening plants With the rapid development of my country's economy and rapid highway construction, highway greening has also become an important measure to improve road landscape and improve the ecological environment. Highway greening can not only beautify the road environment, but also effectively reduce noise and reduce dust., provide drivers and passengers with a comfortable travel experience, which plants should be chosen for highway greening? This article will provide you with a detailed analysis. Selection principle 1. Adaptability: The plants selected should have strong adaptability, be able to grow well in the highway environment, and be tolerant to drought, cold, and salt-alkali.
2. Ecological benefits: Plants should have good ecological benefits, such as sand fixation, wind prevention, dust absorption, noise reduction, etc.
3. Ornamental: Plants should have good ornamental properties, enrich the road landscape and enhance the overall aesthetic feeling.
4. Convenient management: Plants should be easy to manage and reduce maintenance costs. Common highway greening plants 1. Arbors (1) Formosa: It is highly adaptable, drought-tolerant and cold-tolerant, grows rapidly, and has good ornamental and ecological benefits.
(2) Ginkgo biloba: Beautiful tree shape, long life, and strong anti-pollution ability.
(3) White bark pine: The bark is white, the branches and leaves are luxuriant, and it has strong anti-pollution ability.
2. Shrubs (1) Purple-leafed dwarf cherry: The leaves are purplish red and the colors are pink-white, which has high ornamental properties.
(2) Gold-leaf privet: The leaves are golden yellow, resistant to pruning and easy to shape.
(3) Phoebe red-leaf: The leaves are red in color, are resistant to pruning, and have strong anti-pollution ability.
3. Ground cover (1) Ophiopong: Cold-resistant, drought-resistant, grows rapidly, and has good ornamental and ecological benefits.
(2) Iris: Rich in colors, cold and drought-resistant, and has high ornamental properties.
(3) Hemerocallis: Beautiful in color, cold and drought-tolerant, and has strong ecological benefits.
4. Vines (1) Wisteria: Beautiful color, cold and drought-resistant, and has good ornamental and ecological benefits.
(2) Lingxiao: Beautiful color, cold and drought-resistant, and strong anti-pollution ability.
(3) Ivy: It grows rapidly, is cold and drought-resistant, and has high ornamental and ecological benefits.
The selection of highway greening plants should comprehensively consider factors such as adaptability, ecological benefits, ornamental properties and convenience of management. In practical applications, reasonable matching can be made according to specific conditions to create a unique green transportation corridor to improve the effect of highway greening., maintenance management also needs to be strengthened to ensure the healthy growth of plants.
