Abstract: 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.
