摘要:

【Objective】In order to assess the development value of wild zoysia as recreation and sport turf, its comprehensive performance after being trampled was studied. 【Method】In this experiment, hybrid bermuda grass, a popular grass species for playground in Hunan, was used as the control. The effects of different trampling intensity on the appearance quality (color, coverage, density, texture, uniformity), growth and development (biomass, relative growth rate of plant height) and physiological metabolism (relative water content, relative plasma membrane permeability, root activity, soluble sugar content) of wild zoysia and hybrid bermuda grass were studied. 【Result】The mean values of coverage, leaf width, density, uniformity, aboveground/ underground biomass, leaf relative moisture content and offspring system energy of wild zoysia under different trampling treatments were greater than those of hybrid bermuda grass. However, the mean values of chlorophyll content, relative growth rate of plant height, leaf injury rate and soluble sugar content of wild zoysia were lower than those of hybrid bermuda grass. 【Conclusion】Wild zoysia performed better trampling tolerance and it can be used for recreation and sport turf.
