Impact on the climate Natural turf Ping bed is a mixture of sediment, the structure has sufficient porosity in the process of irrigation and precipitation of water accumulation, play a role in conservation of water. When the climate is hot, the lawn grass uses the roots to absorb the water in the depths and transports the large amount of heat in the surrounding environment through the transpiration to effectively reduce the ground temperature and regulate the microclimate within a certain range. The artificial turf has a flat bed structure consisting of rubber, concrete or bitumen, which basically can not play a role of water conservation. Therefore, it can not reduce the surface temperature and its heat capacity is small, resulting in the surface temperature being significantly higher than the air temperature, especially in a closed stadium This problem is even more serious. Summer at noon, artificial turf field can be observed near the surface of the air has obvious heat distortion. The experimental data show that under the high temperature above 30 ℃, the average surface temperature of natural turf is lower than the temperature of 2 ℃ to 3 ℃, while the surface temperature of the artificial turf is higher than the temperature of 6 ℃ to 11 ℃, and with increasing temperature, artificial Lawn surface temperature rise is significantly higher than the natural lawn. In summer, artificial turf surface temperature is very high, if the user at this time and its relatively intense friction, the contact area of the skin will be seriously injured.
The hay residue produced by the natural grass of the final product is transformed into organic matter and returned to the soil under the action of the microorganisms in the sediment. Finally, the remaining non-toxic, harmless mixture of sediment, which can be added to the organic matter used to improve other things.
