To illustrate the control of harmful cyanobacterial growth and the removal of nutritients from fresh water, three submerged macrophytes were grown in the raw water of Guishui Lake. Lindernia rotundifolia, Hygrophila stricta, and Cryptocoryne crispatula were grown together in situ to assess their effectiveness in nutrient removal in microcosms. Results revealed the inhibitory effects of these species on cyanobacterial growth. In addition, water quality in the planted microcosms showed improvement when compared to the water quality of the unplanted microcosm. At all treatments studied, the chemical oxygen demand in the planted microcosms was lower than that in the unplanted microcosms, and the removal rate of all the nitrogen and phosphate in the planted microcosms was better than that of the microcosm without plants. Our study offers a useful algal control method for the lakes or reservoirs that suffer from harmful cyanobacterial blooms.
为了说明对有害蓝藻生长的控制以及从淡水中去除营养物质的情况，在妫水湖的原水中种植了三种沉水植物。圆叶母草、狭叶水蓑衣和皱叶皇冠草被一起原位种植，以评估它们在微观世界中去除营养物质的有效性。结果揭示了这些物种对蓝藻生长的抑制作用。此外，与未种植的微观世界的水质相比，种植的微观世界的水质有所改善。在所研究的所有处理中，种植的微观世界中的化学需氧量低于未种植的微观世界，并且种植的微观世界中所有氮和磷的去除率均优于没有植物的微观世界。我们的研究为遭受有害蓝藻水华的湖泊或水库提供了一种有用的藻类控制方法。
