摘要: 以陕西省安康市2种乡土植物绿萝(Epipremnum aureum)和水葱(Scirpus validus)为对象,设置0.33(对照)、2.00、6.30 mg/L共3个水体初始氨氮浓度处理,通过22 d的水培试验,探究其在冬季低温条件下对水体氨氮的去除效果。结果表明,水葱对氨氮的去除率高达84.50%~93.65%,显著优于绿萝(因根系腐烂导致氨氮释放);水葱组水体pH稳定、溶解氧波动较小,其叶片叶绿素含量(以叶片SPAD值表征)及氮积累量均高于绿萝;绿萝在冬季低温下适应性差,根系腐烂导致二次污染风险升高。因此,建议优先选择水葱作为冬季富营养化水体的修复植物。

Abstract: Taking two native plants Epipremnum aureum and Scirpus validus in Ankang City, Shaanxi Province as the research objects, three initial ammonia nitrogen concentrations of 0.33 (control), 2.00 and 6.30 mg/L were set up. Through 22 days of hydroponic experiments, the removal effect of ammonia nitrogen in water under low temperature conditions in winter was explored. The results showed that the removal rate of ammonia nitrogen by Scirpus validus was 84.50%-93.65%, which was significantly better than that of Epipremnum aureum (which released ammonia nitrogen due to root rot). The pH of the water treated with Scirpus validus was stable, and the fluctuation of dissolved oxygen was small. Additionally, the chlorophyll content (characterized by leaf SPAD value) and nitrogen accumulation in the leaves of Scirpus validus were higher than those of Epipremnum aureum. The adaptability of Epipremnum aureum was poor at low temperature in winter, with root rot increasing the risk of secondary pollution. Therefore, it was recommended to preferentially select Scirpus validus as a restoration plant for eutrophic water bodies in winter.

Key words: aquatic plants, Epipremnum aureum, Scirpus validus, ammonia nitrogen removal, eutrophication, seasonal effects
