| 摘 要： | 采用实验室人工模拟酸性降雨方法，以普通农田土壤作对比，研究郑州市惠济区常规菜地和大棚菜地土壤氮磷在酸雨影响下的流失特征。结果表明，径流中磷素浓度随着降雨时间的延长逐渐减小，氮素浓度随降雨时间变化不明显；氮素主要以颗粒态氮和硝态氯形态流失，磷素主要以颗粒态流失；大棚菜地的氮磷流失量明显大于常规菜地，常规菜地和普通农田的氮磷流失量比较接近。

| Abstract: | By means of artificial simulation of the acid rainfall in laboratory,taking ordinary agricultural soil to contrast,characteristics of nitrogen and phosphorus loss under the acid rain in conventional vegetable soil and greenhouse vegetable soil of Huiji District,Zhengzhou City were studied.The results show that as the rainfall time went on,the concentration of phosphorus in runoff reduced gradually,and the concentration of nitrogen didn't change significantly.Nitrogen loss was mainly in nitrate and particula... |
