The paper discussed the effects of growth agents and mercury on the growth of four herb species subjected to a pot experiment: Aloe vera, Setcreasea purpurea, Chlorophytum comosum, and Oxalis corniculata. We determined the height and biomass production of selected plants treated with different growth agents and different concentrations of mercury solutions. We evaluated the relative growth rate (RGR) of the experimental plants. The aim of the study was to explore potential novel solutions to the shortcoming of the low speed of phytoremediation. The results showed that the upper parts of Aloe vera and Chlorophytum comosum had the fastest growth in the treatment with water only. In contrast, the upper parts of Setcreasea purpurea grew most intensely after the treatment with Lvyebao Fertilizer, whereas the aboveground parts of Oxalis corniculata had the fastest growth after the application of water and the occasional use of Green Cake Fertilizer. In addition, the tolerance to mercury of Oxalis corniculata was the strongest, whereas that of Chlorophytum comosum was the lowest among the species investigated.
本文讨论了生长剂和汞对四种盆栽植物（芦荟、紫背万年青、吊兰和酢浆草）生长的影响。我们测定了用不同生长剂和不同浓度汞溶液处理的选定植物的高度和生物量产量，并评估了实验植物的相对生长率（RGR）。该研究旨在探索解决植物修复速度慢的潜在新方法。结果表明，仅用水处理时，芦荟和吊兰的上部生长最快。相比之下，绿宝肥处理后紫背万年青的上部生长最旺盛，而水和偶尔使用绿饼肥处理后酢浆草的地上部分生长最快。此外，酢浆草对汞的耐受性最强，而吊兰的耐受性最低。
