| 摘要: |
| 利用斜生栅藻(Scenedesmus obliquus)对山东禹城地区碳酸盐水型瘦水与肥水两种水体进行生物改良后,引种短钝溞(Daphniaobtusa Kurz)作室内培养试验研究结果表明,短钝溞在有适宜种类微藻作开拓环境的先驱生物存在条件下,可以耐受碳酸盐型水质,并能成功地生长繁殖,本文还对3种培养液（有机型、无机型、结合型）及两种培养模式（间收式与接种式）下种群增长的动态规律作了初步的探讨。 |

| Abstract: |
| Daphnia obtusa Kurz were cultured in 3 kinds of carbonate hard water, treated by micro-algae (Scendesnus obliquas Turp). The water fleas were harvested in two ways-interval and inoc-ulalting harvests. The results were shown as follows after comparison. In the presence of the algae severed as the pioneer organisms in the water, the water fleas could be inoculated. During the still culture stage without harvest, the population growth curves (N) show that Nc(in the improves fish-farming sewage) > N0(in the pure fish-farming sewage) > Ni(in the improved ground water). During the stage of interval harvest, the mathematical functions of yield (the regression of the general number ranks accumulated from original data gathered each time) in the three kinds of culture medium were all shown to be Logistic growth curve and the population yields shown as Nc Ni N0 and during the stage of noculation harvest: Ni Nc0 N0. |
