摘　　要：以叶片含水量、土壤含水量、植物长势、叶绿素等为指标,分析施用0.2kg/m2、0.4kg/m2、0.6kg/m2等不同浓度的复壮剂(NSR)对高羊茅(Festuca arundinacea Schreb.)及草地早熟禾(Poa pratensis L.)草坪产生的节水与延绿效果。结果表明:施用NSR对草坪植物叶片内叶绿素含量具有一定影响。施用NSR用量控制在0.2kg/m2可以更好地减缓植物叶片中叶绿素含量的流失。与对照组相比较,NSR对植物叶片含水量、土壤含水量等方面影响并不显著,说明NSR不能有效地抑制土壤水分蒸发速率。The effects of Natural soil rejuvenator on Festuca arundinacea Schreb. and Poa pratensis L. turfgrass growth, development and water consumption from several indices variation including leaf water content, soil water content, plant growth and chlorophyll content is analyzed comprehensively. The results showed that natural soil rejuvenator could effectively reduce leaf chlorophyll content loss under 0.2 kg/m^2. But its effects on leaf water content, soil water content and plant growth were still in argument.
