摘 要:以修剪高度、播种量、修剪频率和施N量为因素,利用四因素饱和D-最优设计,对运动场草坪密度进行探讨,最佳四因素水平为:修剪高度4.5cm,播种量15g/m2,修剪频率5次/月,施N量6.78g/m2。并建立了草坪密度与建坪四因素显著相关的回归模型。Under the environmental condition and management level of this experiment, the effects of cuttingheight . seeding rate, cutting frequency and nitrogen fertilizing amount on grass density of sportfield turfwere sludied by the method of FOUR FACTOR STURATED-THE BEST DESIGN. The results showedthat the optimum levels of the four factors affecting density of sportfield turf was 4. 5cm , 15g/m2 , stimes/month and 6. 78g/m2 respectively. And mathematical models of the significant correlations between thefour factors and grass density uas developed.
