摘　　要：本研究以运动场草坪坪床的床土和机械组成(床土含砂量)、基肥磷(P_2O_5)和氮(N)为因素,以草坪品质综合评定得分为衡量指标,利用三因素饱和D——最优设计对运动场草坪坪床结构的优化问题进行了探讨。通过实验得出,最佳坪床结构的三因素水平分别为:床土含砂量67.0820～77.9180％,磷(P_2O_5)0.0131～0.1330克/千克·土,氮(N)0.1122～0.2045克/千克·土;最优三因素水平为:床土含砂量61.8350％,磷0.1067克/千克·土,氮0.1161克/千克·土。文中还建立了草坪品质综合评定得分与坪床结构三因素显著相关的回归模型。Using the Best Design-Three Factors Satuated D, the optimum turfbed formation of the spotfield turf was studied in terms of mechanical formation of the bed (sand content of the soil), basic phosphorous (P_2O_5) and nitrogen (N) fertilizer of the soil. The quality of the sportfield turf is affected by the levels of three factors. Results of this study showed that the appropriate levels of the sand content, basic phosphorous(P_2O_5) and nitrogen (N) fertilizer for the optimum formation of the sportfiled turf were 67.0820%～77.9180%, 0. 0131～0.1330g/kg soil and 0.1122～0.2045g/kg soil and that for the best formation were 61.8350%, 0.1067g/kg soil and 0. 1161g/kg soil respectively. The regression model of the significant relationship between the three factors of the sportfield turfbed formation and the quality of the sportfield turf was also established.
