生态型多层养鳖装置的试验研究

Experimental Research on Ecological Multilayer Equipment for Turtle Culture

介绍了生态型多层养鳖装置的结构原理。成鳖养殖试验表明 ,养鳖水经过红萍的生物净化后可以循环使用 ,水体中 NH+ 4 - N含量保持在 10 mg/ L 以下 ,成功实现高密度、超浅水。

The working principles of the ecological multilayer equipment for turtle culture were described in this paper. Results obtained from experiments showed that the water in this system could be reused through recycling if the water was under biological treatment by use of azolla. The concentration of NH + 4 N in the water was less than 10 mg/L obviously, in comparison with fish farming, the advantages of the equipment are higher in population density, less water requirment and good for intensive culture of turtle.
