"空心菜-水芹"轮作对养殖池塘水质和底质环境的影响
The effect of pond pollutants removal for rotation by water spinach (Ipomoea aquatica)and cress (Oenanthe stolonifera)
摘要
Abstract
The pollutant removal effect towards different cultivation species or quantity on the rotation model by water spinach (Ipomoea aquatica)and cress (Oenanthe stolonifera)has been tested. Contents of the main water quality indexes including total organic carbon(TOC),chemical oxygen demand (COD),chlorophyll (Chl),total nitrogen (TN),ammonium nitrogen (NH +4 -N),nitrite nitrogen (NO -2 -N),nitrate nitrogen (NO -3 -N),total phosphorus (TP)and PO3 -4 -P were measured. TOC,TN and TP in the sediments have also been tested. The results showed that TOC,Chl,TN,NH +4 -N,NO -2 -N,NO -3 -N and PO3 -4 -P significantly decreased in Ganlou herring (Mylopharyngodon piceus)pond before the rotation model (only planting water spinach),while TOC,COD,Chl,NH +4 -N,NO -2 -N,NO -3 -N,TP significantly decreased in Suzhou economic parental fish pond. TOC,NO -3 -N,TP significantly decreased in Ganlou herring (Mylopharyngodon piceus)pond after the rotation model (only planting cress),while TOC,COD,NH +4 -N,NO -3 -N,TP significantly decreased in Suzhou economic parental fish pond. To conclude,TOC,NH +4 -N,NO -3 -N,TP in the water and TOC,TN,TP in the sediment have been significantly reduced by this rotation model "water spinach-cress".关键词
