摘要
以天津市东丽区和西青区2个养殖池塘为对象,采用室内试验方法,研究了底泥中各有机磷组分与上覆水中可溶性磷(DRP)含量、底泥磷酸酶活性与有机磷各组分及上覆水中可溶性磷之间的关系,并采取不同处理对底泥酸性磷酸酶(ACP)和碱性磷酸酶(ALP)活性进行调控。结果表明,底泥中活性有机磷(LOP)、中等活性有机磷(MLOP)、中稳性有机磷(MROP)与上覆水中DRP之间呈显著正相关。底泥中ALP与MLOP、MROP之间相关显著,并对其直接影响较大;ACP与MLOP之间相关显著,对其产生的直接影响也很大。A、B两池塘底泥中ALP与上覆水中DRP随时间变化规律基本一致,二者之间呈显著正相关。在养殖水体中加入酶抑制剂和沸石能抑制ALP和ACP活性,并以酶抑制剂加沸石的处理效果最好。
The aquaculture ponds of Dongli District and the Xiqing District in Tianjin for the two objects.The relationship between organic phosphorus forms in sediments with dissolved reactive phosphorus （DRP） contents in overlying water, and sediment phosphatase activity with organic phosphorus and DRP contents in overlying water had been researched. Different treatments had been taken to inhibite the acid phosphatase （ACP） and alkaline phosphatase （ALP） activity. The results showed that DRP contents in the overlying water were positively correlated with LOP, MLOP. ALP activity with MLOP, MROP had significant positive relation and its direct effect on them was large, and the same results on ACP activity with MROP. The change with time of ALP activity in sediments were same with the DRP contents in overlying water in A, B and had significant positive correlation between them. Adding enzyme inhibitor, zeolite in ponds could inhibite ALP and ACP activity, and the treatment with enzyme inhibitor and zeolite was best of all.
