中文摘要：

以清水、30%二级中水、50%二级中水、100%二级中水灌溉太阳花、虞美人、丹麦草、观叶菊、长寿花等植物.对植物、土壤具体指标的测定表明：植物经不同配比二级中水灌溉长势良好,土壤中的各营养指标明显增加,重金属元素稍有累积,但没有造成污染.二级中水灌溉也会给环境带来一定的负面影响,在施用再生水灌溉绿地时,应定期监测土壤的变化,并结合具体情况对其环境风险进行研究和评价.

英文摘要：

Plants such as Portulaca grandiflora, Papaver rhoeas, Othiopagon japanicus, Senecio cruentus DC and Kalanchoe blossfeldiana were irrigated with Water, 30 % secondary effluent, 50 % secondary effluent and 100 % secondary effluent. The study of plants and soil indexes manifested that：plants were in good condition after irrigated by different irrigation treatments, the level of soil fertility was sharply increased, heavy metal elements was evidently high, but had no significant effect on pollution. Meanwhile secondary effluent irrigation had an adverse impact on environment, so the effect of reclaimed water on soil and plants should be monitored and some actions should be taken when it＇s necessary.
