| 摘 要： | 采用正交试验的方法测试改良剂对草坪草的影响,对主要测试指标进行灰色关联性分析,初步得出施用土壤改良剂能明显地改善坪床土壤理化性质和提高坪用质量.但对不同种类草坪草生长需要的施用量是不一样的,对于草地早熟禾Poa pratensis而言,改良剂在2 kg/m2的水平上关联度最大;对于高羊茅Festuca arundinacea和黑麦草Lolium perenne,改良剂在3 kg/m2的水平上关联度最大;混播草坪对改良剂的施用量不太敏感,在1～4 kg/m2的水平上都是适合的.通过对坪用性状的观察比较,结果与实际生长状况相符,说明用灰色关联性分析方法评价土壤改良剂的施用效果是可行的.

| Abstract: | the effect of soil amendment on turfgrass was tested by orthogonal design,main parameters were analyzed using Grey Relevancy method,which showed that application of soil amendment could significantly improve soil physical and chemical property and turf quality.Different types of turfgrass need different dosage.Poa pratensis gave the highest at 2 kg/m~2;While Festuca arundinacea and Lolium perenne gave good performance at 3 kg/m~2.Mixed turf was not sensitive to the dosage and grow well at 1~4 kg/m~2 dosage.The results of turf characteristics test and turfgrass growth situation indicated that Grey Relevancy analysis is feasible for evaluation of soil amendment effectiveness. |
