摘要
Abstract
The penetration,leaching and transportation of the nitrogen in the soil infiltration process were simulated through soil column experiments under disorderly emissions and non-plant growth conditions.The results showed that ammonium nitrogen concentration decreased with the increase of soil depth significantly under disorderly emissions condition.Concentrations of nitrate nitrogen and total nitrogen of 0～70 cm increased at first,and then decreased before drainage while concentrations of nitrate nitrogen and total nitrogen of 0～70 cm still increased and concentrations of 70～100 cm decreased with the increase of irrigation frequency and amount after drainage.关键词
