| 摘 要： | 重金属Cd污染对土壤硝态氮含量的影响结果表明:低浓度Cd(0.6 mg/kg)使硝态氮含量增加,当Cd浓度为1.0～70 mg/kg时,随着Cd浓度的增加,土壤中硝态氮含量降低;但随着施肥量的增加反而加强了Cd对硝态氮的抑制作用.

| Abstract: | The results of experiment in the effect of heavy metal Cd pollution on the content of nitrate nitrogen in the soil indicated that low concentration of Cd(0.6 mg/kg) could make the nitrate nitrogen content increase,when Cd concentration was at 1.0~70 mg/kg,the content of nitrate nitrogen decreased along with the increase of Cd concentration,but increase of fertilizer application could strengthen the inhibitory action of Cd to nitrate nitrogen. |
