| 摘 要： | 通过测坑试验，研究了黄浦江上游蔬菜田渗漏水中氮素的变化动态和流失规律。结果表明，蔬菜田渗漏水中氮素以NO3^--N为主，NO3^--N作为氮素在土壤中流失的主要形态将成为施用氮肥造成地下水污染的重要来源；施用精制有机肥或粗猪粪代替部分化学氮肥有利于减少蔬菜田渗漏水中氮素的流失。

| Abstract: | Based on the testing\|hole experimentation, the transformation process and rule of nitrogen loss in vegetable fields in the upriver area of Huangpu River were studied. The results showed that NO 3 -\|N was the main nitrogen form in vegetable field leaching water. As the main form of nitrogen loss in the soil, NO 3 -\|N would be an important source to pollution the groundwater after fertilization. In order to decrease lea\| ching loss of nitrogen in vegetable fields, it was suggested using refined organic fertilizer and coarse pig ordure to replace a part of chemical fertilizers. |
