摘　　要：以高冰草、黑麦草和苇状羊茅为试材,采用数据分析法,研究了不同修剪方式对3种草坪草形态特征的影响,并对不同修剪方式下草坪草分蘖能力进行分析,找出草坪最佳观赏质量的修剪方式,分析高冰草、黑麦草和苇状羊茅的分蘖能力与修剪高度的关系,以期获得草坪高观赏质量的修剪方式,从而为开发草坪草新品种提供参考依据。结果表明:在高冰草、黑麦草和苇状羊茅中,修剪留茬高度为6 cm的3种草坪草均表现出较好的分蘖能力,综合评分最高;修剪留茬高度为4 cm和8 cm的3种草坪草的分蘖能力一般,综合评分为中等;修剪留茬高度为0 cm的3种草坪草的分蘖能力较差,评分最低。修剪留茬高度为6 cm的草坪颜色最深,均一性较好,草坪质量良好;修剪高度为4 cm和8 cm的草坪颜色和均一性一般,草坪质量中等;各对照的草坪质量较低于各修剪组,且表现较差。Taking Agmpymn elonglum,Lolium perenne and Festuca arundinacea Schred as test materials,the method of data analysis was used.Effects of three kinds of turfgrass morphological characteristics were studied.Best viewing quality of lawn pruning method was found by analyzing the tillering ability of lawn grass under different pruning methods,and the relationship between tillering ability and pruning height of Agmpymn elonglum,Lolium perenne and Festuca arundinacea Schred was analyzed to obtain high ornamental quality pruning methods,in order to provide a basis for the development of new varieties of lawn grass.The results showed that all three kinds of grass with 6 cm stubble height showed better tillering ability,the highest comprehensive score was found in Agmpymn elonglum,Lolium perenne and Festuca arundinacea Schred.The tillering ability of three kinds of grass with 4 cm and 8 cm was average and the comprehensive score was medium.And the tillering ability of three kinds of lawn grass with stubble height of 0 cm was poor and the score was the lowest.The lawn with stubble height of 6 cm was the deepest,uniform and good lawn quality,the lawn color and uniformity of 4 cm and 8 cm were general,and the lawn quality of each control group was lower than that of each pruning group,and the performance was poor.
