摘　　要：研究了NH4HCO3、（NH4）2SO4、NaNO3、NH2CONH2、NH4Cl和NH。H2PO46种氮源对小球藻生长的影响。每组的氮质量浓度均为50mg/L，均添加磷质量浓度为3mg/L的NaH2PO4作为磷源，培养9d。试验结果表明，各处理组在第3—5d时小球藻的生长指标达到最大值，添加NH4HCO3组对小球藻生长的促进作用最明显，细胞密度、吸光度、干重和叶绿素含量等指标都显著高于其他处理组（P〈0．05），其次为NaNO3和NH2CONH2，而（NH4）2SO4、NH4Cl和NH4H2PO4效果不明显。The effects of six kinds of nitrogen sources including NH4HCO3, （NH4 ）2 SO4, NANO3, NH2 CONH2, NH4Cl and NH4H2PO4 on growth of alga Chlorella vulgaris were studied at a rate of 50 mg/L when NaH2PO4 was used as P source at a rate of 3 mg/L. The best growth was observed in the chlorella exposed to NH4 HC03 （ P 〈 0.05）, compared with other N sources, followed by NaNO3 and NH2 CONH2, but no significant effect was observed in the chlorella exposed to （NH4） 2SO4, NH4Cl and NH4H2PO4.
