The purpose of this study was to reveal the alternative effcient interaction between mowing height and mowing frequency in Kentucky bluegrass turf management. The Kentucky bluegrass cultivar ＇Kenblue＇ （Poa pratensis L.） was used to evaluate the interactions of mowing heights （H1, H4 and H7） and mowing frequencies （F2, F5 and F8） on the performance of turfgrass and turf physiological responses under the feld condition. The results showed that the treatment of H7×F8 had perfect infuence on the turf texture, root elongation, and also enhanced soluble sugar and free proline content in plants. While, the turf quality, color, uniformity and the increasing tiller numbers were performed more superior in the treatment of H4×F5 than other treatments. In all the interacting treatments, the relation between leaf green index and number of shoots （dm2） was positively correlated, thus, it could be speculated that the proper mowing height with frequency had a strong impact on the increasing of turfgrass tillers. On the whole, the interaction of H4×F5 on turf quality was the most excellent treatment in this experiment.展开更多
