摘　　要：通过实验室试验结合池塘试验的方法研究了光合细菌（Photosynthesis Bacteria;PSB）对重盐碱地区养殖池塘水质的影响。结果表明：施用不同剂量的PSB后试验组pH变化不大,DO（溶解氧）显著升高,COD（化学耗氧量）、NH4^＋-N、NO2^--N显著降低,Alk（总碱度）、CO3^2-、HCO3^-、NO3^--N、PO4^3--P变化不明显;试验池塘与施用同浓度的试验组的水质因子变化规律相似;PSB适宜施用浓度为6.68×10^11个/m^3,周期为8-10d。The effect of PSB on water quality control through plastic box and pond test in the heavy saline was studied.The results showed that PSB had little impact on pH;it significantly increased on DO;contrary results were obtained for COD,NH＋4-N,NO-2N,and it had no significant impact on ALk,CO2-3,HCO-3,NO-3-N,and PO3-4-P after the application of PSB.It had similar results in the pond.The appropriate concentration and applying period of PSB was 6.7 1011/m^3 and 8 to 10 days.
