Types and applications of hedges and green walls

In all kinds of green space, in order to avoid the boring elevation of retaining wall between two highlands with different heights, hedges are often planted in front of retaining wall to beautify the elevation of retaining wall. Let me share with you the types and applications of hedges and green walls. Welcome to read and browse.

I. Types of hedges and green walls

The opaque wind structure of any regular forest belt consists of one or two rows of shrubs or small trees at equal intervals, which are called hedges and green walls.

According to different heights, it can be generally divided into four types: green wall, high hedge, hedge and short hedge.

1. 1 hedges and green walls? The average person's eye height is above 160cm, which can block people's sight and can't see the outside. This kind of hedge is called hedge and tree wall.

1.2 high hedging? Where the height is below 160cm, and the average person's chest height is above 120- 130cm, people can still see through it, but the height is not something that ordinary people can skip. This kind of hedge is called a tall hedge. For example, the new Chang 'an factory in Yubei District of Chongqing uses coral trees as high hedges to divide the space and block people's sight.

1.3 Intermediate hedging? Hedges whose height is below DBH 120cm, but above 50cm, which people have to struggle or jump over, are usually called middle hedges. Hedge is the most commonly used hedge in general garden green space. Plants are often used in the isolation belt of streets in the main city of Chongqing. For example, lilacs are used as middle hedges along the Yangtze River in Yuzhong District, and the effect is very good.

1.4 short hedging? Any hedge whose height is less than 50 cm that people can pass through without difficulty is called a short hedge. This kind of hedge can be seen everywhere on the edge of flower beds and green belts in many parks and urban streets.

Second, the function and ornamental requirements of hedges and green walls

According to the different functions and ornamental requirements of hedges and green walls, hedges in gardens can be divided into evergreen hedges, flower hedges, colored leaf hedges, fruit-viewing hedges, thorn hedges, deciduous hedges and vine hedges.

2. 1 evergreen hedge

In the gardens or houses of institutions, schools and residential quarters, in order to prevent or separate the space quickly, and because tall hedge seedlings can't be obtained at the moment, it is often necessary to establish lattice bamboo fences, wooden fences or steel fences first, and plant lianas at the same time. Climbing the wall has another feature. For example, in order to prevent tennis from flying too far and increase the distance of picking up the ball, steel wire mesh walls are often used to cover it, and this mesh wall also needs climbing plants to beautify it.

2.6 Hedging

In order to increase the defensive function of the hedge and prevent tourists or animals from passing through, sometimes the branches of the hedge are woven into nets or grids.

2.6. 1 Strong germination and regeneration, easy to produce adventitious buds, dense branches and resistant to pruning.

2.6.2 Leaves are small and dense, flowers are small and dense, and fruits are small and numerous, which are easy to transplant and can be propagated in large quantities.

2.6.3 There is a certain growth rate.

Thirdly, the application of hedges and green walls in gardens.

Hedges have the functions of separating space, blocking sight, reducing noise, beautifying the environment and serving as the background of fountains or statues in gardens.

Hedges and green walls are widely used in gardens. According to different requirements, different plants in different places have the following applications.

3. 1 for prevention and closure

For example, ornamental lawns in gardens, foundation planting, fruit tree areas, and conventional ornamental planting areas that tourists cannot enter. , often surrounded by hedges to prevent pedestrians from crossing at will. Hedges can also organize the route of tourists. The impassable areas are fenced with hedges, and those that can pass are cleared.

3.2 Many conventional garden uses

Take the middle fence as the dividing line; Use short hedges as the edges of reading glasses, flower beds and ornamental lawns. Hedges used to decorate horizontal stripes are generally made of Buxus microphylla, Syringa microphylla, Acer truncatum, Holly, Murraya murraya, Buxus macrophylla, conifers and Japanese cypress. Buxus macrophylla and Buxus macrophylla are the most ideal. Because boxwood grows slowly, it is easy to prune, the pattern is not easy to go out of shape, and it is more durable. Ivy can also be used to form a kitchen pattern.

3.3 As a barrier and organizational space

In conventional gardens, tree walls are often used to block the view or separate garden spaces with different functions. Tree walls are used to replace photo walls, shadow walls and fences in buildings. This hedge is best in the form of a high green wall composed of evergreen trees above the line of sight. Usually in natural gardens, local strong contrast is covered by gaps. Children's games or open-air theaters, open-air dance floors, tennis courts and other sports venues are separated from quiet rest areas to shield the line of sight, isolate noise and reduce mutual interference.

3.6 Hedging portfolio production

Hedges are widely used in landscaping, especially as perimeter hedges, with a large scale. If it can be combined with production, it will have great benefits. For example, hedgerows such as Salix psammophila, Sophora japonica and Snow Willow can be woven into baskets after cutting off branches. Those with high aesthetic requirements, such as perfume rose and honeysuckle, have high economic value. In addition, grapes can be used as hedges, gardenia, osmanthus, laurel and so on. And the effect is very good.

Therefore, understanding the types, functional requirements and ornamental requirements of hedges and green walls in urban landscaping will play an effective role in forming hedges and green walls, making extensive use of various plants and enriching the landscape effect of urban greening.
