| 采用旱伞草为试验原料，通过简单的炭化处理工艺制取一种新型廉价的吸附剂。研究了炭化旱伞草在不
同氨氮浓度下吸附时间、投加量、吸附温度、pH、粒径等因素对其去除效果的影响，并采用傅立叶红外光谱分析对该

| 英文摘要: |
| Phosphate-solubilizing microorganism (PSM) can help to mobilize insoluble phosphorus for phytoplankton to
use. However, the number of PSM in aquaculture pond is small. In this paper, the quantity and distribution of PSM, the
adaptation scope and phosphate-solubilizing effect were reviewed. Furthermore, the feasibility of application of PSM in
aquaculture pond was discussed. In view of the current culture situation, the prospect of the future research direction was
made based on the preliminary research on the application of PSM in aquaculture environment. The application of
exogenous efficient phosphate-solubilizing microorganisms can promote the phosphorus cycle and improve the utilization
ratio of phosphorus in aquaculture pond. So the application of PSM in aquaculture pond is feasible. |
