| 摘 要： | 通过正交实验研究了4种典型微量营养元素P、Fe、Mn、Zn对常见藻华生物指标的影响,结果表明:增加P表现为提高藻类生长速率和最终生物量,对藻生长周期和蓝藻种群地位无显著影响；Fe、Zn分别在质量浓度为0.05mg/L、0.01 mg/L以内促进藻类生长,在质量浓度分别高于0.1 mg/L和0.01 mg/L后抑制藻类生...

| Abstract: | Mirco-nutrients exert significance impacts on fresh water plankton biomass.Through orthogonal experiments the promoting effects of typical micro-nutrients(P,Fe,Mn and Zn) on algae bloom organisms(Cyanobacteria) were are studied.The experimental results obtained show that the algae biomass had has a linear increasing relationship with the concentration of phosphorous(ranging from 0.04~0.32 mg/L).Algae growth rate was is promoted at with the concentration below Fe(0.05 mg/L) and Zn(0.01 mg/L),while it is was ... |
