摘要
采用室内实验的方式研究了无机氮和有机氮对不同微藻增殖的影响情况。比较了不同氮源 (氯化铵和尿素 )对纤细角毛藻 (Chaetocerosgracilis)、赤潮异弯藻 (HeterosigmaakashiwoHa da)、亚历山大藻 (Alexandriumsp.)、隐藻(Chroomonassalinaf.adolenscens)4种海洋微藻生长的不同影响。结果表明 ,有机氮尿素对海洋微藻增殖的影响比无机氮的复杂。由微藻最适生长的氮、磷浓度得到N∶P值 ,讨论了该值对微藻增殖的影响 ,以及影响N∶P值的可能情形。
The effects of different nitrogen source,such as ammoniumchloride and urea,were studied in this paper.Four micro algae,Chaetoceros gracilis,Heterosigma akashiwo Hada,Alexandrium sp.,Chroomonas salina f.adolen-scens,were selected for these experiments.The results showed that the effect of urea on micro algae growth was more complex than that of ammonium chloride.The effect of N:P ratio was also discussed in this paper,and some factors which may affect the ratio were also discussed.
