氮肥对地下水中氮迁转机理研究
Mechanism of Migration and Conversion of Nitrogen Fertilization in Groundwater
摘要
Abstract
By analysing main factors affecting the migration and conversion of ammonia-nitrite-nitrates in groundwa-ter,we aim to provide theoretical basis for the prevention and control of agricultural non-point source nitrogenous pollution.Qianyanzhou test station in Jiangxi Province was selected as research object and experiment plots were di-vided.The groundwater table,ammonia-nitrite-nitrates,ferrum-manganese and pH value of groundwater in the re-search area were monitored in long term.Through data sorting,diagram analysis and SPSS software,we analysed the correlation among ammonia-nitrite-nitrates,total iron,manganese in filtering state and pH value.Results sug-gest that the groundwater in the study area has been affected by agricultural non-point nitrogenous pollution.Ferro-manganese in groundwater are apparently associated.Ammonium nitrogen and nitrite nitrogen are positively related with ferro-manganese.Total iron,manganese in filtering state,pH value,temperature and rainfall are the main im-pact factors of the transport and transformation of ammonia-nitrite-nitrates in the groundwater.关键词
