In order to explore different effects of forms of nitrogenous fertilizer on growth and Cd accumulation of maize(Zea mays L.)in seedling stage，the hydroponic exposure experiment with Cd(5 mg/L)and different levels(4 and 8 mmol/L N)of nitrogenous fertilizer(Nitrate，NO^3-；Ammonium，NH4+；and Urea)was conducted.After 12 days of culture，the differences in growing status and Cd accumulation of maize under different forms of nitrogenous fertilizer treatments were investigated.The results showed that the Cd significantly inhibited the growth and development of maize seedling compared with the total nutrient solution culture without adding Cd.Under heavy metal stress，the application of nitrogenous fertilizer significantly promoted the seedling growth and accumulation of Cd in maize.Compared with the other treatments，the Cd enrichment coefficient of maize with NO^3--N application was up to 204.0，164.5 times higher than that in CK treatment.The Cd enrichment coefficient of maize treated with NH4+-N fertilizer was between 3.36 and 9.51，indicating that the promoted absorption was not obvious.However，the Cd transport coefficient of maize with NH4+-N application was 0.19～0.21，which was 3.8～4.2 times of that for CK.The promotion effect of urea treatment on the growth and Cd accumulation of maize was between that of NO^3--N and NH4+-N treatments.However，there was no significant effect of nitrogenous fertilizer with the different application levels on the growth and Cd accumulation of maize.Therefore，both the economic yield of corn and heavy metal accumulation should be weighed in the production practice.The absorption of heavy metals in maize could be regulated by appropriate fertilization application，which provide reasonable fertilization management measures for production practice.
