摘要
凤眼莲净化污水的生态效益和经济效益与其生长量及生长状况有直接或间接的关系,凤眼莲在不同环境中的生长情况、产量及与环境因子的关系过去人们已经有不少研究。但由于凤眼莲的生长受地域、温度、光照。
The growth of water hyacinth and its relationship with environmental factors in silverbearing waste water are studied in Wuxi cine-film factory. Based on experimental results, the intrinsic growth rate K and environmental holding capacity r of water hyacinth in different months are determined, its growth curves are also fitted. In addition, laboratory static experiments are made for the injury of silver on water hyacinth. The injury threshold and critical doses of different forms of Ag on water hyacinth are determined.
