卤虫培育池的初级生产力

Primary Production in Artemia Culture Ponds

对主施鸡粪和投喂精面粉的3个不同放养密度的卤虫培育池中初级生产力进行研究,结果表明:1#、2#、3#的浮游植物毛产氧量分别为0.21、0.24、0.17gO2/(m2·d);浮游植物群落净产量分别为0.10、0.16、0.05gO2/(m2·d);水呼吸耗氧量分别为0.11、0.13、0.11gO2/(m2·d);P/R系数>1.5,初级生产力极低。

The primary production in Artemia culture ponds with three kinds of densities which are mainly discharged with hen dropping and fed with wheat gluten are studied.The results indicate that primary productivity was very low.The gross oxygen production of Phytoplankton in 1#,2# and 3# pond were 0.21 gO_2/(m^2·d),0.24 gO_2/(m^2·d),0.17 gO_2/(m^2·d) and net oxygen production of Phytoplankton were 0.10 gO_2/(m^2·d),0.16 gO_2/(m^2·d),0.05 gO_2/(m^2·d).The oxygen consumptions of water-breathing were 0.11 gO_2/(m^2·d),0.13 gO_2/(m^2·d),0.11 gO_2/(m^2·d).P/R>1.5.The primary productivity was very low.
