The selection of slope greening plants is an important part of slope greening engineering, which directly affects the greening effect, ecological function, and slope stability. The following is a detailed introduction to slope greening plants: 1. Principles for selecting slope greening plants
1. Adaptability: Choose plants that are suitable for the local climate and soil conditions to ensure that they can grow normally and achieve a green effect.
2. Growth rate: Priority should be given to plants that grow rapidly in order to cover slopes in a short period of time and reduce soil erosion.
3. Root characteristics: Choosing plants with developed root systems and strong soil consolidation ability can help enhance the stability of slopes.
4. Ecological benefits: Consider the ecological benefits of plants, such as improving air quality, increasing biodiversity, etc.
5. Economic cost: On the premise of ensuring the greening effect, choose plants with lower cost, easy planting and management. 2、 Common slope greening plants
#1. Herbal plants
Dogtooth Root: It has strong adaptability to the environment, simple cultivation, and low planting cost, making it an excellent lawn grass.
Tall fescue: With strong adaptability, drought and cold resistance, it is a commonly used grass species for slope greening.
Large leaved grass: grows rapidly, has good coverage effect, and is suitable for slope greening.
Baixicao: tolerant to drought and poverty, grows rapidly, and can effectively prevent soil erosion.
Knot grass: It has strong resistance to stress and trampling.
#2. Shrubs
Purple locust: With a well-developed root system, it is tolerant to drought, cold, and poor soil conditions, making it an excellent plant for soil stabilization and slope protection.
Sea buckthorn: It has strong adaptability, drought resistance, wind and sand resistance, and can grow in harsh environments.
Lemon strips: cold resistant, drought resistant, high temperature resistant, can prevent wind and fix sand.
Lespedeza: It has a wide adaptability, can improve soil, and maintain water and soil.
Purple leaved Berberis: With strong adaptability and beautiful leaf color, it can be used for slope beautification.
#3. Trees
Robinia pseudoacacia: Strong adaptability, well-developed root system, and good soil stabilization function.
Cypress: drought resistant and cold resistant, with low soil requirements, able to grow on barren slopes.
Masson pine: tolerant to drought and barrenness, it is a common species for slope protection.
Ailanthus altissima: grows rapidly, has strong adaptability, and can adapt to dry slope environments. 3、 Planting methods of slope greening plants
1. Cage planting: Using cement fixed cages to plant vegetation, suitable for steep slopes.
2. Desktop planting: Building steps on the slope and planting vegetation on the steps, suitable for slopes with gentle slopes.
3. Bag planting: Plants are planted in bags, and then the bags are stacked on a slope to form a plant wall, suitable for various slopes.
4. Surface planting: directly planting plants on the slope, which can be planted as a whole or in combination with multiple plants to form a colorful effect. 4、 Suggestions for the combination of slope greening plants
1. According to the slope conditions, for slopes with poor stability, poor soil, and steep slopes, more herbaceous plants and shrubs should be selected; For slopes with good stability, optimal soil conditions, and gentle slopes, the proportion of trees can be appropriately increased.
2. Pay attention to ecological functions: When matching plants, attention should be paid to their ecological functions, such as soil stabilization and slope protection, improving air quality, etc.
3. Considering landscape effect: While ensuring the greening effect, the ornamental value of plants can be considered to form a distinctive slope greening landscape.
The selection of slope greening plants should comprehensively consider multiple factors, including adaptability, growth rate, root characteristics, ecological benefits, and economic costs. Meanwhile, reasonable planting methods and matching suggestions are also key to achieving slope greening effects.
