The Influence of Traffic on Turfgrass Root Growth and Sports Quality of Stitched Hybrid Turf with Different Stitch Depth
Stitched hybrid turf establishment techniques involve parameters such as stitch density and depth.There are differences in the effectiveness of different stitch density and depth in promoting the growth of turf-grass and enhancing the quality of turf.In this experiment,we used natural turf(CK)as the control,and set up five stitch depth treatments(6 cm,9 cm,12 cm,15 cm,18 cm)to study the effects of traffic on the quality of turf,root growth and sports quality of stitched hybrid turf with different stitch depth.The results showed that:the increase of rebound rate and surface hardness of stitched hybrid turf with different stitch depth could be slowed down after traffic;the total root length and surface area of the root system were higher than those of the control when the stitch depth was 9 cm and above,and the total volume of the root system of the hybrid turf with 6 cm stitch depth was significantly lower than that of the control;the average diameter of the roots of the turf with 18 cm stitch depth was increased.This study shows that the root morphology parameters can be improved to a certain extent by stitching hybrid turf with a stitch depth of 9 cm or more,which can improve the quality and sports performance of soccer field turf after traffic,among which,the 18 cm depth of stitching has the most prominent effect,and it is not recommended to plant hybrid turf with a stitch depth of 6 cm.
