| 摘 要： | 选取了北方地区常用草坪草高羊茅为研究对象,探究了保水剂在屋顶绿化草坪草栽培应用中的最优施用制度及经济效益。结果表明：在50%～70%FC水分控制下高羊茅生长所需的耗水量比70%～90%FC水分控制下的耗水量要小,且任意水分控制条件下,施用保水剂处理组的总耗水量均比对照组的总耗水量要小;当保水剂施用浓度为0.5%,施入层...

| Abstract: | The festuca arundinacea,the most common grass in the northern area of China,is used in this experiment.The best applied system and economic benefits of superabsorbent used in the glass of roof greening are explored.The results show that the water usage of festuca arundinacea under 50%~70%FC is less than that under 70%~90%FC.Besides,no matter which condition it is,the water usage of experimental groups which use superabsorbent is less than that of matched groups.When the consistence of water-retaining agent ... |
