| 摘 要： | 研究了不同Ca2+浓度条件下,三角帆蚌养殖水体中的细菌总量、致病性肠道菌和葡萄球菌及藻类的增长情况。研究结果表明:实验水体的细菌总量增长呈现出比较完整的逻辑斯谛增长特性,Ca2+对细菌总量的增长起着调控作用,Ca2+浓度越高,对于细菌的生长抑制就越明显。对于致病性肠道菌,10mg/L组Ca2+浓度有利于增长,20mg/L和30mg/L组在后期具有明显的抑制增长的作用。葡萄球菌在20mg/L的Ca2+浓度下增长最快,30mg/L组则明显抑制葡萄球菌的生长。在10￣30mg/L的Ca2+浓度范围内,水体中藻类的增长不受Ca2+浓度控制。

| Abstract: | The growth of bacteria, pathogenetic-coli, staphylococcus and algae in Hyriopsia cumingii aquaculture water under the condition of different Ca2 concentration were studied. The result showed that the growth of bacteria accorded with the logistic equation. The Ca2 controlled the total bacteria amount. The higher the Ca2 concentration, the more significant the bacteria inhibition was. As for the pathogenetic-coli, the 10 mg/L concentration of Ca2 in Hyriopsia cumingii was beneficial to their growth, and 20 mg/L and 30 mg/L had significant inhibition functions on the growth later. Staphylococcus grew fastest under the concentration of 20 mg/L Ca2 and its growth was significantly inhibited at 30 mg/L. In the range of 10 mg/L~30 mg/L, the growth of the algae was not controlled by Ca2 concentration. |
