摘要: 为了研究沉水植物苦草和轮叶黑藻的对水环境的影响,在控制条件下单独种植苦草、轮叶黑藻和二者混种,笔者比较研究了苦草、苦草 黑藻、黑藻组合水体中总氮(TN)、总磷(TP)、铵氮(NH4 -N)、叶绿素a、总悬浮质(TSS)及总有机氮(TOC)浓度的区别。结果表明:苦草和轮叶黑藻对水环境的影响不同,单独种植苦草时,上覆水中总氮和氨氮含量高于其他处理,但总磷、叶绿素、TSS和TOC含量都低于轮叶黑藻单种和混种处理。研究结果说明,苦草对于降低上覆水中总磷和叶绿素含量作用优于轮叶黑藻,对维持水体水质有良好效果。

Abstract: The paper aims to study the influence of submerged plants Vallisneria natans and Hydrilla verticillata on water environment, Vallisneria natans and Hydrilla verticillata were planted alone and mixed under the restrained conditions. The authors comparatively studied the concentration difference of total nitrogen (TN), total phosphorus (TP), ammonium nitrogen (NH4 -N), chlorophyll-a, total suspended mass (TSS) and total organic nitrogen (TOC) in the water of Vallisneria natans alone, Hydrilla verticillata alone and mixed of the two. The results showed that: the influence of Vallisneria natans and Hydrilla verticillata on water environment was different. When Vallisneria natans was planted alone, the content of total nitrogen (TN) and ammonium nitrogen (NH4 -N) in overlying water was higher than the other two processing methods, but the content of total phosphorus (TP) and chlorophyll-a, TSS and TOC were lower than that of Hydrilla verticillata planted alone and the mixed planting of the two. The results also showed that Vallisneria natans which could reduce the content of total phosphorus and chlorophyll-a in overlying water was better than Hydrilla verticillata, it had a good effect on maintaining water quality.
