中文摘要:
      水葫芦具有良好的净水能力,但并未作为水质改良的途径进行推广。在模拟加州鲈养殖生态 的池塘中施放密度为10 株/m2 的水葫芦,与不作处理的池塘作对比,处理8 d 后,通过测定模拟池塘水体 pH、氨氮、亚硝酸盐、总氮及总磷浓度等水质指标,底泥有机物及全磷含量等指标及池塘浮游生物量,评价 水葫芦对加州鲈高密度精养池塘水体的净化作用。结果表明,水葫芦对水体pH 无明显影响,水体中氨氮最 大去除率达60.9%,总氮最大去除率达59%。水葫芦处理后,底泥有机物的最大去除率达65.6%,全磷的最大 去除率达46.9%。水葫芦对浮游生物总量影响不明显,但显著降低了绿藻、蓝藻生物量,在一定程度上控制 了浮游植物种群结构。
英文摘要:
      Water hyacinth( Eichhornia crassipes) is good at water purification,but so far it has not been widely used in water quality improvement and aquaculture ecological restoration. To investigate the effects of water hyacinth on water quality,sediment deposition and plankton,water hyacinth was planted( 10 plants per square meter) in largemouth bass( Micropterus salmoides) aquaculture pond for 8 d. The results showed that the water hyacinth had no obvious effect on the Power of hydrogen( pH) of the water,the maximum removal rate of ammonia nitrogen( NH4 +-N) in the water was 60.9%,and the total nitrogen( TN) removal rate was 59%. After treatment of water hyacinth,the maximum removal rate of sediment organics was 65.6%,and the maximum removal rate of sediment phosphorus was 46.9%. The effect of water hyacinth on the total amount of plankton was small,while the biomass of Chlorophyta and Cyanobacteria was significantly reduced,and it suggested that water hyacinth could manipulate the structure of phytoplankton population.
