摘要
我国沿海富营养化程度愈来愈严重,富营养化是发生赤潮和水华的物质基础.菊花江蓠可以快速而大量地吸收环境中的无机营养盐,江蓠与微藻在营养上是竞争的关系.本试验对不同菊花江蓠放养密度系统脉冲加富N、P,只有当系统中的江蓠密度不少于0.75kg/m3时,江蓠能去除添加的大部分N(95.36%)和P(38.01%),较好地控制和减少微藻水华的发生.
Increasingly serious degree of eutrophication has been regarded in the coast of China, and it is the material base of red tides or water blooms. Red macroalgae Gracilaria lichevoides enables to uptake inorganic nutrients rapidly and largely in environments, and the relationship between macroalgae and microalgae is competitive. In this article, nutrienpulse-enrichment in the systems with different density of stocking macroalga is made.It is observed that only when macroalga density more than 0.75kg/m^3, 95.36% N and 38.01% P added in pulse-enrichments are removed by the macroalgae, and the water blooms of microalgae are controlled well.
