摘要
利用延绳式在室外养殖虾池种植水蕹菜,研究其对养殖池塘水质与养殖产量的影响效果。试验结果显示,种植水蕹菜后池塘水体透明度、TN、TP、CODMn和叶绿素a稳定性都优于对照池,微生物量变化较对照池也明显稳定。种植池每667 m2收获水蕹菜鲜重200.8(±3.3)kg,水蕹菜对投入水体的氮吸收率为3.18%,磷吸收率为1.79%。种植池中对虾产量以及对水体氮磷去除率略高于对照池。虾池种植水蕹菜不仅能有效改善水质,还可提高养殖的经济效益。
To investigate the water quality and aquatic production in an aquaponic system, the aquatic vegetable Ipomoea aquatic was planted on floating beds in outdoor shrimp ponds. Results showed that water quality indices including water transparency, TN, TP, CODMn, chlorophyll-a and microbial biomass were more stable than those in control. The fresh weight of I. aquatic was 200.8（±3.3） kg, the removal percentages of TN and TP were 3.18% and 1.79%, respectively. The shrimp production and the rate of removal nitrogen and phosphorus in planded pond were slightly higher than those in control ponds. The results suggested that the water quality could be improved effectively and a higher shrimp density could be stocked in the ponds planted I. aquatic.
