| 摘 要： | 调查了长江三角洲苏卅、镇江、扬州、宜兴、常州市的蔬菜大棚和露天菜地种植情况,并采集土壤样品测定了土壤硝态氮含量.结果表明,江苏省长江三角洲蔬菜地土壤无论是多年大棚菜地还是露天菜地,都有较为严重的硝态氮残留.设施蔬菜地土壤硝态氮含量比露天菜地的普遍要高,按平均值比较依次为,宜兴＞常州＞扬州＞镇江＞苏州.露天菜地土壤硝态氮残留依次是常州＞苏州＞镇江＞宜兴＞扬州.其中,设施蔬菜地土壤硝态氮含量最高值出现在宜兴达88.4mg/kg,通过分析采样信息得出,环太湖地区蔬菜地土壤硝态氮污染程度较大,地下水的污染加重了土壤的污染.

| Abstract: | The paper reports the investigation result of vegetable cultivation in greenhouses and open-air and their soil nitrate nitrogen contents in Suzhou,Zhenjiang,Yangzhou,Yixing and Changzhou of Yangtze River Delta.The results showed that there is a lot of nitrate nitrogen residual in soils of greenhouses and open-air vegetable lands and the soil nitrate nitrogen content of greenhouses is generally higher than that of open-air lands.The soil average nitrate nitrogen value in greenhouses is Yixing>Changzhou>Yangz... |
