Abstract:

In order to further understand the characteristics of natural-artificial turf, this research tested some physiological indices of natural-artificial turf after mimic traffic processing, with the control group of natural turf. The result shows that the effects of light traffic on the plasma membrane permeability, chlorophyll content and soluble sugar content of natural-artificial turf are not obvious as those of non-traffic processing, and the changes of SOD activity and MDA content also proved this. However, heavy traffic has tremendous impacts on every aspects of turfgrass growth thus reducing turf quality. In natural-artificial turf system, the natural turfgrass is protected by the artificial turfgrass and the stability of the turf is strengthened so that the changes of every physiological index are smaller. But in group A2, due to the over density of artificial turfgrass, the growth of natural turfgrass is affected so that the visual quality of the turf is poor. The protection of artificial turfgrass is not obvious in group A8 compared with the control group A0. However, in group A4 and group A6, the turf is less impacted by traffic and the protection is very obvious thus greatly improving the traffic resistance of the natural-artificial turf.
