为研究浮床水蕹菜对池塘养殖水质的改善效果,于2007年6月至11月,在6个2000m2的标准养殖池塘进行了中试研究.3个池塘放养常规鱼类和部分名优鱼类,并利用浮床技术在水面上种植200m2的水蕹菜(Ipomoea aquatica),另外3个池塘放养相同重量的常规鱼类作为对照塘.实验结果显示,种植塘的渔产量为1467kg,显著高于对照塘1203kg的渔产量(p<0.05).对照塘中TN去除率为25.17%,TP为15.27%;种植塘中TN去除率为30.02%,TP为21.68%;种植塘收获水蕹菜鲜重(4000±350)kg,TN去除率为8.41%,TP为4.85%.在养殖实验的中后期,种植塘水体的TN、TP、COD和Chla都显著低于对照塘,而透明度显著高于对照塘,溶解氧保持在5mg·L-1以上.这种综合养殖模式不仅能有效改善水质,减少养殖废水对环境的污染,还可提高养殖的经济效益. |

To investigate the nutrient removal in an aquaponic system,pilot scale tests were carried out in six earthen ponds of area 2000 m2 from June to November in 2007.The aquatic vegetable Ipomoea aquatica(200 m2 area)was planted on floating beds in three ponds.The other three ponds without the vegetable were considered controls.The same fish weight was stocked in the planted and control ponds,but with different fish species.At the end of experiment,the fish production in planted ponds(1467 kg)was significantly higher than in control ponds(1203 kg)(p<0.05).Percentage removal of total nitrogen(TN)and total phosphorus(TP)by harvested fish in the control ponds was 25.17% and 15.27%,respectively.Percentage removal of TN and TP by harvested fish in the planted ponds was 30.02% and 21.68%,respectively.The fresh weight of harvested vegetable was(4000±350)kg;and the percentage removal of TN and TP was 8.41% and 4.85%,respectively.In the middle and late period of the experiment,the contents of chemical oxygen demand(COD)and chlorophyll a(Chl a)in the planted ponds were significantly lower than in the control ponds,and the transparency was significantly higher than in the control ponds.The concentration of dissolved oxygen(DO)in planted ponds was higher than 5 mg · L-1 during the experiment,whereas the concentration of DO in the control ponds decreased sharply in the last month.The results suggested that the water quality could be improved effectively and a higher fish density could be stocked in the aquaponic system. |
