为探讨再生水短期灌溉对绿地植物生理指标、矿质元素及土壤理化性状的影响,用清水、混合水和再生水分别对沟叶结缕草、海滨雀稗、叶子花及黄金香柳进行了为期3个月的灌溉试验。结果表明：混合水灌溉增加了草坪草的叶绿素含量,对草坪草电解质渗透率、丙二醛含量和矿质元素及土壤环境无显著影响。再生水灌溉降低了土壤 pH,增加了土壤电导率、速效 K 及 Na 含量,对 Cu 和 Zn 含量无显著影响,而全 N 和速效 P 含量在不同土壤中存在一定的差异；其次,再生水灌溉对4种草坪草均未造成显著伤害,增加了部分植物电解质渗透率、丙二醛含量、叶片全 N 和 Na 含量,但对草坪草叶绿素含量、速效 P、速效 K、Cu 及 Zn 含量无显著影响。因此,混合水可以做为城市绿地灌溉的优质水源,再生水亦可短期用于城市绿地灌溉。

To investigate the effects of reclaimed water irrigation on plant physiological indexes,mineral ele-ments and soil physical and chemical properties,the tap water,mixed water and reclaimed water were used for irrigation to Zoysia matrella ,Paspalum vaginatum ,Bougainvillea spectabilis and Melaleuca bracteata for 3 months,respectively.The results showed that the mixed water irrigation increased chlorophyll content,but had no significant effects on electrolyte leakage,malondialdehyde content,mineral elements and soil environment.In addition,on the one hand,reclaimed water irrigation reduced soil pH,increased soil conductivity,available K and Na content,but had no significant effects on Cu and Zn content.Besides,the differences of total N and available P content were found among different plant soil.On the other hand,reclaimed water irrigation had no significant damage to four kinds of plants.Moreover,the electrolyte leakage,malondialdehyde content,leaf total N and Na content of some plants were increased after irrigation of reclaimed water,but no significant effects were found in chlorophyll content,available P,available K,Cu and Zn content.Therefore,mixed water can be used for irriga-tion in urban greenbelt as a suitable water source,and reclaimed water can also be used for short-term irrigation in urban greenbelt.
