Speaking of lawn, we should be familiar with it. From park greening to stadium application to three-dimensional landscape, there are shadows of artificial turf. Artificial turf plays an indispensable role in urban construction, which has become one of the symbols of civilization of a country and a city. However, the turf we see can be divided into artificial turf and natural turf. In the application of urban environment, they play a role in greening the environment, but also have different characteristics. When artificial turf meets natural turf, its advantages and disadvantages are clear at a glance

1. Requirements for foundation

Natural turf: Before paving, the site must be natural soil, and the procedure is complicated. It needs to loosen the soil, water, fertilize, maintain, etc. to release oxygen, and can absorb toxic gases such as sulfur dioxide, hydrogen fluoride, ammonia, chlorine, etc. to purify the air.

Artificial turf: the site can be paved directly after the hardened foundation is completed, saving construction time and low maintenance costs in the later stage.

2. Service life and maintenance of the site

Natural grass: service life is usually 2— It needs to be updated within 4 years and must be maintained by special personnel. Maintenance needs to be managed by specially-assigned person, which is costly and time-consuming. Due to the weather and competition conditions, turf needs to be maintained, repaired and protected frequently.

Artificial turf: the service life of artificial turf is up to 8— 12 years, no later maintenance costs.

3. Security

Natural grass: It is non-combustible. The soft texture of natural grass makes the surface of the lawn have proper smoothness. The heat generated by friction is within the range of human tolerance, and will not cause harm to human body; The natural lawn has moderate hardness and resilience, and athletes can make various technical actions at will without fear of serious injury due to falling; The natural lawn is composed of green plant lawn grass. The stems and leaves are fine and soft, and will not generate static electricity when the human body rubs against them.

Artificial grass: anti-UV, anti-UV and anti-static solvents are added to the artificial grass during the production process, without any potential safety hazard.

4. Strength serviceability

Natural grass: After a large-scale high-intensity competition, it must be maintained immediately. The natural grass cannot meet the needs of 24-hour high-intensity sports.

Artificial turf: Artificial turf has no use frequency problem and can be used all day long. Compared with natural turf, the advantage of artificial turf in sports characteristics lies in its excellent uniformity and flatness, which can fully avoid the bad condition of the ground caused by climate, maintenance and other factors, thus affecting the competition.

5. Site practicability

Natural grass: after rain, the anti-skid ability is weak, the turf is easy to shovel off, and the stability is poor. Maintenance and inspection are required before use.

Artificial grass: made of acrylic fiber material, with excellent anti-skid performance and improved friction.
