温度、光照和磷质量浓度对小环藻、大型溞和金鱼藻共培养的影响
|
摘要
为了研究温度、光照和磷质量浓度对生物操纵效果的影响,选用小环藻、大型溞和金鱼藻分别作为浮游植物、浮游动物和大型水生植物的代表种,建立不同磷质量浓度(0.05、0.1、0.5、2mg/L)的水生微宇宙模型,研究不同温度梯度(15、20、25、30℃)、不同光照强度(1000、2600、4200、5800lx)及不同光暗比(10∶14、12∶12、14∶10、16∶8)条件下浮游动物和沉水植物的控藻效果.结果表明:磷质量浓度为0.05~0.5mg/L、温度在20~25℃时,大型溞和金鱼藻生长较好,对小环藻有明显的抑制作用;磷质量浓度为0.05~0.5 mg/L、光照强度在1000~4200lx时,大型溞和金鱼藻对小环藻有明显的抑制作用;强光(5800lx)有利于小环藻、金鱼藻的生长,但对大型溞有抑制;磷质量浓度为0.05~0.5mg·L-1,光暗比为14h∶10h时,大型溞和金鱼藻生长最好,可以达到很好的抑藻效果;当磷质量浓度相同时,温度30℃、光照5800lx时,培养液中氮磷去除率最高.
In order to study the influence of temperature,illumination and phosphorus concentration on the effect of biomanipulation.Cyclotella sp.,Daphnia magna,Ceratophyllum demersum have been selected respectivelys as representatives of phytoplankton,zooplankton and submerged macrophyte,to establish the model of aquatic microcosm under different phosphorus mass concentrations(0.05,0.1,0.5,2mg/L)to research the joint-inhibiting effect on algal of zooplankton and the submerged macrophyte under different temperature gradient(15,20,25 and 30 ℃),different light intensity(1000,2600,4200,2600lx)and different light/darkness ratio(10h∶14h,12h∶12h,14h∶10h,16h∶8h).The result indicates that when phosphorus concentration was 0.05mg/L to 0.5mg/L,temperature was 20-25 ℃,Daphnia magna and Ceratophyllum demersum grow better,which exerte significantly inhibition on Cyclotella sp.When phosphorus mass concentration was 0.05mg/L to 0.5mg/L,under the condition of light intensity between 1000-4200 lx,there is one stronger joint-inhibiting effect on Cyclotella sp of Daphnia magna and Ceratophyllum demersum.When phosphorus concentration is set as 0.05mg/L to 0.5mg/L,it is advantageous to the growth of Cyclotella sp.and Ceratophyllum demersum in strong light intensity(5800lx)condition,but goes against the growth of Daphnia magna.When phosphorus concentration was 0.05 mg/L to 0.5 mg/L,light/darkness ratio of was 14h∶10h,daphnia magnwcan ceratophyllun demersum grewbest,and can lead to a very good controlling effect on Cyclotella sp.Under one certain phosphorus concentration,when the temperature was 30℃,illumination is 5800 lx,there is one high removal efficiency of nitrogen and phosphorus in the medium.
