Effects of gradient irrigation on turf quality of Kentucky bluegrass

on the basis of water balance principle, a linear gradient irrigation experiment was conducted to investigate the influence of soil moistures on turf density, color, texture, uniformity of Kentucky bluegrass in the Xinjiang region. The results of this study showed that Kentucky bluegrass turf showed a better color, uniformity and density when soil moisture was 60%-70% of field water capacity, but the turf texture of Kentucky bluegrass was not different under the different soil moisture, indicating that soil moisture did not affect the turf texture of Kentucky bluegrass. Comprehensive estimation showed that the appearance quality of Kentucky bluegrass turf was better and Kentucky bluegrass grass was health when soil moisture was 60%-70% of field water capacity.
