摘　　要：[目的]研究氮磷配施对野牛草草坪质量的影响。[方法]采用不同氮磷用量配比施肥,测定野牛草叶片叶绿素含量及草坪色泽和密度,并对草坪综合质量进行评分,研究氮磷配施对野牛草草坪质量的影响。[结果]在供试土壤养分状况下,施肥向土壤中提供了植物生长所需的养分,使草坪草产生了一系列有利于它们生长和生存的变化,从而改善了草坪外观。随氮素用量的增加,野牛草叶片叶绿素含量升高,草坪色泽、密度和综合质量评分均提高,而磷素作用不大。[结论]氮的施用可明显提高野牛草草坪质量。[Objective] The aim was to study the effect of the nitrogen and phosphorus fertilization ratios on the turf quality of buffalograss [Method] The different ratios of nitrogen and phosphorus fertilizer were applied,the chlorophyll content,turf color and turf density were measured,and the comprehensive quality of the turf were scored to study the effect of the nitrogen and phosphorus fertilization ratios on the turf quality of buffalograss.[Result] Under the nutrient conditions in the tested soil,the fertilization provided the nutrients required for the plant growth in the soil,which made the turf grass produce a series of the change that was beneficial to their growth and survival,thus improving the lawn appearance.With an increase in the amount of nitrogen fertilizer,the chlorophyll content in the leaves of buffalograss was increased,and the color and density of the turf and the comprehensive quality scores of turf were all improved,while the phosphorus fertilizer had no effects on these mentioned above.[Conclusion] Appling the nitrogen fertilizer could significantly improve the turf quality of bufallograss.
