Study On The Effect Of Trampled On Stitched Hybrid Turf

Implantable artificial natural mixed lawn refers to the use of professional equipment according to a certain distance and depth of the implanted artificial turf root layer of a flat bed reinforced turf.Four strands and six strands were selected for silk planting,and perennial ryegrass and tall fescue were selected for grass planting.The effects of silk planting on turf growth,physiology and leaf damage of two turf grasses under trampling stress were studied by simulated trampling treatment.The results show that:1.Under moderate trampling stress,the appearance quality,density and coverage of 4-strand and 6-strand silk-planting turfgrasses were significantly better than those of non-silk-planting turfgrasses,while under severe trampling stress,the advantages of silk-planting turfgrasses were not significant2.The surface hardness,compactness,torsional friction coefficient and resilience of tall fescue silk-planting turf bed were significantly higher than those of non-silk-planting turf bed,and perennial ryegrass was significantly higher than non-silk-planting turf bed only under trampling stress.The movement quality of silk-planting turf bed of two turf grasses changed less under trampling stress than that of non-silk-planting turf bed.Under trampling stress,it can maintain the stability of turf bed movement quality.3.Without trampling stress,silk planting had no significant effect on leaf physiological characteristics of both species.Under trampling stress,the relative water content and chlorophyll content of 4-strand and 6-strand silk-planting Turf-beds of tall fescue were significantly higher than those of non-silk-planting turf-beds,and the relative membrane permeability of leaves was significantly lower than that of non-silk-planting turf-beds.Under severe trampling stress,the relative membrane permeability of perennial ryegrass silk-planting turf was significantly lower than that of non-silk turf,and the soluble sugar content of tall fescue leaves was significantly lower than that of non-silk turf.
