摘要/Abstract

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分别在浓度为0.05 mg/L、0.01 mg/L以内促进藻类生长，在质量浓度高于0.1 mg/L和0.01 mg/L后抑制藻类生长，而Mn在质量浓度低于0.05 mg/L和高于0.1 mg/L条件下都有促进藻类生长的可能；Fe、Mn、Zn质量浓度与藻类生长周期成正比关系；Fe质量浓度越高，蓝藻的优势地位越明显，Mn与Zn对藻类的种群结构影响微弱.

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 inhibited at with the concentration above Fe (0.1 mg/L) and Zn(0.04 mg/L). Manganese(Mn) showed has no regularity obvious influence on algae biomass and algae growth rate., It is possible to stimulate algae growth with concentration of Mn below than 0.05 mg/L or above than 0.1 mg/L. The results show that phosphorous had has no effect on algae growing cycle, while there is a direct proportion between the concentrations of iron, manganese and zinc and the lag phrase of algae. Mn and Zn show no impact on algae community structure, but high Fe is beneficial to Cyanobacteria.
