摘    要:初步研究了在低洼盐碱地池塘中光合细菌(PSB)施用后对浮游生物的影响。研究结果表明:(1)光合细菌的施入,促进了浮游植物中蓝藻门、绿藻门、隐藻门、裸藻门的数量和生物量的增长;硅藻门总体上有所下降,但小型种属增加;(2)光合细菌的施入,促进了浮游生物中枝角类、轮虫,尤其小型轮虫的增长,而桡足类和原生动物却表现出下降趋势;(3)浮游生物总体上表现为数量增加而生物量下降,但绝大部分种属均有不同程度的增加,而且浮游生物种类趋向于小型化,从而增加了鱼类有效的天然饵料,因而光合细菌的施入,可以调整并优化盐碱地池塘的浮游生物的群落结构。

关 键 词:光合细菌  池塘  盐碱地  浮游生物  PSB  蓝藻门  绿藻门  桡足类  原生动物

Abstract:The research on improving efficiency of PSB to plankton structure in low-lying saline-alkaline wetland ponds showed that PSB could enhance the number and the biomass of Cyanophya,Cyptophyta,Euglenophyta and Cryptophyta. Although Bacillariophyto dropped a little in general,the small-type species increased.Moreover,PSB could enhance the number and the biomass of Cladocera and Rotifera,especially those of the small-type Rotiferus.But those of Capepoda and Protozoa displayed a dropping tendency.Generally plankton displayed increases of numbers and decreases of biomass. Most species of plankton appeared certain increase,small-size geneses of plankton appeared more common than great-size ones,which incrased the feed effect for fishes.In conclusion PSB could adjust and improve the structure of plankton community in saline-alkali wetland ponds.
Keywords:PSB  Low-lying saline-alkali wetland  ponds  plankton
