| 摘 要： | 通过测定草坪剪草量,应用Logistic模型,以各时段剪草量和各时段累计剪草量作为各时段和试验阶段的k值估计量,分析确定了草坪最大经济修剪量,并提出每次修剪标准应为 k/2,既可维持草坪生态系统平衡,又可保持草坪生产性能。

| Abstract: | In this experiment,the maximum sustainable cutting quantity of turfgrass was estimated by Logistic mathematical model. Results showed that the maximum economic cutting quantity is k/2 with one cutting(K is a estimative value),which not only maintains the ecosystem equilibrium,but also keeps the basic function of turf |
