| 摘 要： | ４因子，２水平（铁为４水平）正交试验表明：络合铁和硝态氮对海洋原甲藻的生长有极显著的促进作用（Ｐ＜０．０１），维生不Ｂ１，Ｂ１２混合液有显著促进作用（Ｐ＜０．０５）。络合铁和硝态氮为大鹏湾浮游植物生长的营养限制因了。而磷酸盐的作用不显著。

| Abstract: | Seawater was collected from Dapeng Bay, South China Sea, in Oct., Nov., 1991and Jan., 1992. Growth promoting nutrients were examined by using AGP (Algalgrowth potential) test procedure. Inorganic nitrogen, phosphorus, chelated iron andvitamin B1,B12, mixture were supplemented at various combinations and concentrationsaccording to the orthogonal designed scheme.The results showing that the maximum standing crop of Prorocentrum micanswas enhanced very remarkably (P<0.01) by nitrate and chelated iron and remarkably (P <0.05) by a mixture of vitamin B1 and B12 but that phosphate had no remarkable effect suggested that in Dapeng Bay the former three factors are crucial intriggering red tide in the area. |
