| 摘 要： | 生物方法作为一种新兴的赤潮防治方法,因为其作用的专一性及较少的负效应,越来越受到人们的重视。研究了龙须菜(G racilaria lem aneif orm is)与东海原甲藻(P rorocentrum d ongha iense)之间营养盐NO3-、PO43-竞争的情况。结果显示,两者共培养时,龙须菜对营养盐的快速吸收利用,使得共培养体系中营养盐迅速降低,最终导致东海原甲藻消亡,而东海原甲藻对于龙须菜的生长不构成明显的影响。在营养盐充分的条件下,1g鲜重的龙须菜对NO3-的吸收能力相当于6.0×107个东海原甲藻细胞,对PO43-的吸收相当于2.4×107个东海原甲藻细胞。相对于东海原甲藻,龙须菜对营养盐的吸收利用更具有优势。龙须菜可作为有效吸收营养盐的大型海藻,用以降低近海水域富营养化程度及有害赤潮发生的几率。

| Abstract: | The harmful algal blooms(HABs) are occurring in more locations than ever before and have caused serious destruction to the coastal marine environment and massive mortality of cultured organisms.Various mitigating methods,such as physical or chemical ones,have been proposed,but the results are not desirable because of their unpredictable impacts on marine ecosystem.Biological strategies are thus suggested for its potential HABs mitigating ability with little side effects.Macroalga is popular in aquatic ecosy... |
