| 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／ｍ＾２，修剪频率５次／月，施Ｎ量６．７８ｇ／ｍ＾２。并建立了草坪密度与建坪四因素显著相关的回归模型。

| Abstract: | 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. |
