Abstract/Contents:"In the coming years there will be a trend towards an increase in recreational lawn area in large cities. How to best manage this recreational lawn is an important research subject in which recovery management is one of the key issues. This study was conducted to determine the effects of a variety of mechanical methods including coring aerification, vertical mowing, and raking, in addition to fertilization, on the quality of traffic Zoysia matrella lawn. The experiment utilized a split-plot design with the mechanical methods forming the main plots and fertilizer the subplots. The height of turfgrass and the length of the second leaf from the top were shown to significantly increase under the coring aerification, vertical mowing and raking treatments compared with the control treatment, with the height of turfgrass increased by 34.64%, 27.71% and 39.26%, respectively, and length of leaf increased by 24.03%, 17.05% and 31.78%, respectively. The restoring-induced increase in height and length lasted for a period of 50 days. The turfgrass density and above-ground biomass (AGB) were significantly higher in the restoring plots than in the control plots, where the turfgrass densities were increased by 15.2%, 10% and 14.4% in the treatments of coring aeration, vertical mowing and raking, respectively, compared with the control treatment. Further, AGB increased by 23.37%, 11.84% and 22.16% in the treatments of coring aerification, vertical mowing and raking, respectively, compared with the control treatment. Coring aerification and raking was shown to reduce thatch. The fertilizer treatment significantly increased turfgrass height, leaf length, AGB, and turfgrass density (P<0.05). There was a significant interaction effect between mechanical restoring methods and fertilizing on AGB and turfgrass density (P<0.05). Overall, the effects of restoring in early summer were greater than in autumn; the effects of coring aerification method, 100-120 core/m2, on improving lawn were greater than vertical mowing; with the raking treatment most effective when carried out in spring."
