摘　　要：农业生产造成的自身污染是一个不可忽略的环境问题。化肥施用不当造成植物体内硝酸盐含量增加以及水源的污染，城市活性污泥的农用处理，扩大了农田中重金属污染的途径和范围。因此要提倡科学种田，合理施肥，以减轻对农业环境的污染。The problem of agricultural environmental pollution caused by agricultural production has brought to more and more attention today. Because of the improper application of fertilizers, the nitrate content in plants will be increased and the sources will be polluted. The farming disposal of sludge from city sewer treatment plant will expand the scope and approaches to heavy metal pollution in farmland. Therefore, the rational fertilization and tillage must be advocated to reduce the pollution of agricultural environment.
