摘要： 用模拟践踏器研究践踏对沟叶结缕草(Zoysia matrella)坪用性状的影响。试验设对照、轻度、中度和重度践踏4个践踏强度,结果表明,对照和轻度践踏下,草层高度、叶片长度和活生物量均明显高于重度践踏;中度践踏强度下草坪草层高度、叶片长度随着降雨量和灌溉次数变化而呈现波动式消长规律。对照和轻度践踏的草坪密度随着践踏时期的延长而呈现持续下降的趋势,但中度和重度践踏的草坪密度在9月份时呈现增加的趋势,并且重度践踏草坪增加的幅度明显高于中度践踏;轻度、中度、重度践踏草坪的地上活生物量依次增加,但轻度与中度践踏在践踏的前2个月差异不显著(P>0.05),之后出现显著差异(P<0.05);而中度和重度践踏的草坪地上活生物量差异均不显著(P>0.05)。对于沟叶结缕草草坪而言,如果采取较粗放的养护措施,轻度践踏强度比较适宜即75kg重,每隔4d践踏10次;如果采取比较好的、适时的养护措施如适时灌溉、施肥和封闭恢复,中度践踏强度(即75kg重,每隔2d践踏10次)也可以维持比较好的草坪坪用质量。

Abstract: This experiment was conducted to examine response of phenotypic traits of Zoysia matrella to traffic stress(TS)using a traffic machine.Four treatments of traffic stress were imposed in the experiment,which were control(CK),light traffic(LT),moderate traffic(MT)and heavy traffic(HT).Turf height,leaf length and green biomass extended and increased more significantly(P<0.05)in CK and LT than those in HT,while turf height and leaf length varied in MT with the change of rainfall or watering frequency.Tiller density decreased in CK and LT during the whole experimental period,but increased in MT and HT in September.There was a significant difference(P<0.05)in green biomass between LT and MT after two-month traffic stress,but there was no significant difference between MT and HT during all experiment period.As a result,the green biomass was the richest in LT,and scarcest in HT.These results suggest that Zoysia matrella turf could maintain good quality in LT treatment even if turf management was incomplete,and with MT treatment if turf was properly managed.
