摘  要:
为了解南四湖流域主要类型农田肥料和农药的流失情况,以流失率为指标,分析了南四湖流域平原水田、旱田的地表径流、地下淋溶肥料、农药流失情况。结果表明,平原水田氮、磷、农药流失的主要途径是径流水;常规施肥条件下氮、磷、毒死蜱、氟虫氰流失率随着降雨量的增加而增加,其平均流失率分别为13.21%、2.65%、12.84%、18.72%,氮的流失率远大于磷。常规施肥条件下旱田氮、磷、毒死蜱流失率随着降雨量的增加而增加,其中氮、磷流失率较水田高,且氮的流失率远大于磷,分别为20.89%、3.36%;毒死蜱流失率较水田低,为3.59%。

摘  要:
In order to investigate the characteristics of losses for different land utilization patterns in Nansi Lake basin,paddy land and dry land were selected to investigate fertilizer and pesticide loss using surface runoff and leaching method.The results showed that surface runoff was the main approache that nitrogen fertilizer,phosphorus fertilizer and pesticide lost in paddy land.Under the conditions of conventional fertilization,the loss percentage of nitrogen fertilizer,hosphorus fertilizer,chlorpyrifos,fiproni increased with the increase of rainfall,the average loss percentage of which was about 13.21%,2.65%,12.84%,18.72%in paddy land;the average loss percentage of which was about 20.89%,3.36%,3.59%in dry land.
