在分批培养条件下，研究了Fe、Mn对单养和混养塔玛亚历山大藻生长和细胞大小的影响，以及与之混养的中肋骨条藻和圆筛藻的生长特性。μg/dm 3）和Mn（0-0 18？结果表明，Fe、Mn浓度越高，3种单胞藻的数量越多，说明Fe、Mn是赤潮发生的重要因素，在混养条件下，小细胞的中肋骨条藻和圆筛藻的生长状况较好，但随着时间的推移，其生长状况逐渐下降，说明Fe、Mn浓度和培养条件对赤潮藻的生长有较大影响。
Under batch culture condition,we studied Fe and Mn effects on the growth and cell size of uniculcured and polycultured Alexandrium tamarense and the growth characteristics of Skeletonema costatam and Coscinodiscus sp.polycultured with it.Results showed that under experiment condition,Fe(0—3 15?μg/dm\+3) and Mn(0—0 18?μg/dm\+3),the number of three unicu Hared algae increased with of Fe and Mn,which indicated that Fe and Mn are important causing factors of red tides.Under polyculture condition, S.costatam and Coscinodiscus sp with small cells were more properous than A.tamaranse which declined after a while.In short Fe,Mn density and culture condition have considerable effects on the growth of A.tamaranse.
