摘　　要：为研究再生水灌溉对几种常规园林植物、土壤和浅层地下水水质的影响,试验于2017—2020年在河北省石家庄市栾城区洨河湿地东侧的绿化带内,筛选梧桐、榆树、女贞、月季、马莲、鸢尾和海棠等7种常规园林植物进行再生水灌溉。结果表明:同自来水灌溉对照相比,再生水灌溉的7种常规植物叶片中N、P、K和Na的含量增大了1.4%~37.7%;微量元素含量增加了0.7%~48.5%;重金属元素Cr和Cd的含量增大了1.9%~22.9%;Cu的含量增加了4.4%~22.7%;再生水灌溉的土壤全盐量、Na+和pH的增大不明显,而氯化物含量增加了25.1%~86.3%。7种常规植物土壤养分较对照均略有增加,但差异不大。洨河再生水灌溉条件下7种常规园林植物均长势较好,未见有生长异常现象,土壤没有产生明显的恶化,地下水除总硬度外均符合标准,但应进行长期的监测。The effects of reclaimed water irrigation on mineral elements,soil environment and shallow groundwater quality of several common garden plants were studied.The experiment was carried out from 2017 to 2020,and seven kinds of garden plants including plane tree,elm,privet,moon season,horse lotus,iris and begonia were selected for reclaimed water irrigation in the green belt green space on the east side of the Xiaohe Wetland in Luancheng District,Shijiazhuang,Hebei Province.The results showed that the contents of nitrogen,phosphorus,potassium and sodium in the leaves of 7 plants treated with reclaimed water increased by 1.4%~37.7%compared with tap water irrigation.The content of trace elements increased by 0.7%~48.5%;The content of heavy metal elements Cr and Cd increased by 1.9%~22.9%.The copper content increased by 4.4%~22.7%;The total salt content,sodium ion content and pH value of the soil under reclaimed water irrigation were not significantly increased,while the chloride content increased by 25.1%~86.3%.The soil nutrients of the seven plantings increased slightly compared with the control,but there was no significant difference.7 conventional garden plants grew well under reclaimed water irrigation on the Xiaohe River.No abnormal growth was observed and no obvious deterioration of the soil was observed.All the groundwater met the standard except for the total hardness.However,long-term monitoring should be conducted.
