摘要
采用室内控制实验,以多年生黑麦草、高羊茅和草地早熟禾3种北京市常见冷季型草坪草作为研究对象,研究再生水灌溉及其对照自来水灌溉下不同物种高温胁迫下根系长度、重量及其活性氧清除系统的特性,结果表明:再生水对高温胁迫下高羊茅的根系生长有明显的促进作用,对多年生黑麦草及草地早熟禾则表现出不同程度的抑制作用。再生水灌溉刺激高温胁迫下高羊茅和多年生黑麦草保持较强的生理优势,草地早熟禾则在再生水和高温胁迫的双重作用下生长发育受阻。
Limited water resources in Beijing have created greater interest on the part of municipalities to utilize nonpotable waters in urban areas. Researches were conducted to understand the effect of reclaimed water irrigation on growth and antioxidant system in cool-season turfgrass with temperature stress. The results are as follows: irrigation with reclaimed water has different effects on heat tolerance of different materials. The reclaimed water keeps the activity of antioxidant enzyme in perennial ryegrass and tall fescue higher than the control test,while for Kentucky bluegrass,a decrease in antioxidant enzyme activities would occur.
