| 摘 要： | 通过调查和地下水田间采样,对广州市白云区部分露天蔬菜地的土壤和地下水中的硝酸盐氮含量进行了测定分析。结果表明,土壤中全氮含量为0.122%,属中上水平,菜地地下水的硝酸盐氮浓度范围为0.13~49.84 mg/L,出现超标现象。分析了地下水中硝酸盐含量升高的主要影响因素,指出过量施肥会造成地下水硝酸盐污染。

| Abstract: | The contents of nitrate in soils and groundwater samples from the vegetable cultivation area base in Baiyun District of Guangzhou City was analyzed.The results indicated that the content of nitrogen in the soil was 0.122% which ranged between medium to high level,the concentration of NO3——N in groundwater was 0.13～49.84 mg/L,some of samples exceeded the standard.The main factors affecting nitrate content in groundwater were discussed.The impropriated usage of the chemical fertilizer would cause nitrate contamination in soil and groundwater. |
