Abstract: In the pot experiment carried out in a green house , Ipomoea aquatica was grown at different nutrient levels of nitrogen and potassium to study their performance with regard to the growth, lead content, lead uptake ability and total lead translocation of Ipomoea aquatica, while the soil lead was 500mg/kg. The results revealed that different N,K levels had significant effects on the dry weight, lead content and the total lead translocation of Ipomoea aquatica. The sole nitrogen fertilizer and the combination of K and low N fertilizer could increase the dry weight ,advance the lead uptake and translocate lead from the roots to the shoots of Ipomoea aquatica. But the sole potassium fertilizer could decrease the lead uptake ability and the plant total lead translocation.It is indicated that Pb uptake ability and the total lead translocation of plants can be increased by regulating N,K nutrient levels in Pb-contaminated soil.
