Abstract: An investigation of the same mowing heights(4 cm and 8 cm) on turf grass community structure which was mixed by different percentages of tall fescue(Festuca arundincea L.) and kentucky bluegrass(Poa pratensis L.) was conducted. The results show that in moist subtropical zones, the higher the proportion of tall fescue, the more stable the community(20% KB+80% TF >40% KB+60% TF >60% KB+40% TF >80% KB+20% TF), and the narrower the blades of grass at the initial growing stage. As the percent of tall fescue shoots increases per unit area, the width of blades of tall fescue in different mixture is the identical, and any discrepancy in the average growth speed is not obvious.
