摘　　要：为探讨修剪高度和频度对冷季型草坪草生长及外观质量的影响机理,本研究对不同修剪高度和频度下冷季型草坪草高羊茅和多年生黑麦草的生长速率及外观质量进行了研究,结果表明:及时修剪可以保持草坪整齐一致,增加美感,调节草坪生长,增加草坪密度,提高竞争力,减少杂草侵入。提出每周修剪2次比1次更能促进高羊茅和黑麦草草坪的生长;低茬比高茬修剪能促进高羊茅和黑麦草草坪的生长。从外观质量评定结果看,高羊茅/黑麦草以高茬修剪为好;修剪对高羊茅/黑麦草的根系长度和生物量的影响程度在各个处理间均不显著。In current study two cold season grasses, such as tall tescue and perennial ryegrass, were usea to mvesngate me effect oi mowing height and frequency on the growth and appearance quality for these two turf grasses. The results revealed that mowing twice a week can promote the growth of tall fescue and perennial ryegrass; low stubble mowing can also promote their growth rate. However, for appearance quality assessment, the high stubble mowing had better performance for these two grasses. And for the root length and biomass of these two grasses, the treatment of mowing didn＇t show significant influence.
