Study On The Threshold Of Durable Tolerance Of Sport Turf

A model of durable tolerance of sport turf was established in this study according to on-the-spot sampling, together with and different treatments of trampling. The durable tolerance of sport turf was obtained based on determinations of the several indexes of turf grass. 1. The index of soil tolerance was typical and representative, which was examined through three ways (treatments) and statistical analysis 2. The relation matrix was set up according to the similarity of the Dical muster in Fussy mathematics, the growth coefficient was obtained according to Haiming Distance, together with the ranges of soil tolerance, the relation model, namely the model of durable tolerance was established. The additional and natural maintenance and improvement management after treading can be matched to this model, thus, the scientific and systematic management on turf will be fulfilled by depending on computer. The durable tolerance of sport turf does not simply mean the treading intensity and management efficiency, the typical and representative physiological factors affecting the growth of turf, such as water, light and nutrients should be paid more attention. The function of the turf should be ensured, mostly the turf was used to control soil, and the management is extensive for this type of turf, but as for the Golf Green, Tee and Course, the management is more intensive, due to frequent cutting and treading. Therefore, this study was conducted to offer basic ideas for efficient management, and scientific evaluation on sport turf.
