摘　　要：以单细胞雨生红球藻为试验材料,以MAV为培养基通过单因子试验和正交试验研究了Cu2+、Zn2+、Co2+3种微量元素离子对雨生红球藻生长的影响。单因子试验结果表明,Cu2+、Zn2+、Co2+最佳质量浓度分别为2.0×10-7、3.4×10-7、9.0×10-7mol/L。正交试验结果表明,Cu2+的最适质量浓度是2.0×10-8mol/L;Zn2+的最适质量浓度是3.4×10-7mol/L;Co2+的最适质量浓度是6.0×10-7mol/L.。在这3种重金属离子的正交试验中在所研究的浓度范围内Cu2+和Co2+存在着较显著交互作用。Using the single cell Haematococus pluvialis as the experiment object and the MAV as the media , the effect of Cu^2 ＋ , Zn^2 ＋ , Co^2＋ on Haematococus pluvialis growth was studied by single factor experiment and orthogonal experiment . The single factor experiment result indicated that the best concentrations which effect the Haematococus pluvialis growth were Cu^2＋ ：2 ×10^-7 mol/L; Zn^2＋：3.4 ×10^-7 mol/L; Co^2＋ ：9 ×10^-7 mol/L. The orthogonal experiment consequence indicated that the best concentrations which effect the Haematococus pluvialis growth were Cu^2＋ ：2 ×10^-8 mol/L; Zn^2＋ ：3.4 ×10^-7 mol/L; Co^2＋ ：6 ×10^-7 mol/L. In addition,the Cu^2＋ and Co^2＋ mutual effect on the Haematococus pluvialis growth was significant under the concentration range of this study.
