生物浮床在高产池塘中的应用试验

Application Tests of Bio-floating Beds in High-yield Ponds

使用生物浮床实现池塘水质原位净化是改善养殖水体水质条件的有效途径。不同面积比例的水蕹菜浮床对池塘水体中的NH4+-N浓度的影响试验结果表明,在本地资源禀赋条件下,水蕹菜浮床对于高产池塘水体具有显著的净化作用。浮床面积分别为10%、20%时,池塘氨氮的平均去除率分别达到23%、35%,去除效果明显。

The use of bio-floating beds to realize in-situ purification of pond water quality is an effective way to improve water quality of aquatic water.The influence of swamp cabbage floating beds with various area ratios on NH4+-N concentration in pond water was studied.The results showed that with resource endowment,the swamp cabbage floating beds could greatly purify the high-yield ponds.With the floating-bed areas of 10%and 20%,the average removal rates of NH4+-H could reach 23%and 35%,respectively.The removal efficiency was significant.
