摘　　要：应用水量平衡原理,通过线性梯度灌溉,控制对草坪草的灌溉量,研究新疆地区不同水分处理对草地早熟禾(Poa pratensis)草坪密度、色泽、质地、均一度的影响。结果表明,草地早熟禾草坪在B3(田间最大持水量的60%～70%)水分处理下可以得到较好的色泽、均一性和密度,但草地早熟禾质地评分在不同水分处理间差异不大,表明水分不能有效影响草地早熟禾质地。通过对不同水分处理下的草地早熟禾草坪质量进行综合评分,经方差分析发现草地早熟禾草坪在B3水分处理下就可以满足其生长需求,达到较好的外观质量。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.
