摘要：土壤可溶性有机氮是土壤氮素的重要组成部分,也是氮循环过程中最活跃的因子之一。土壤可溶性有机氮不仅可以直接被植物吸收利用,也可以被土壤微生物利用。土壤可溶性有机氮可以随土壤水分向下迁移造成农业面源污染等环境问题,所以引起众多研究者关注。从土壤可溶性有机氮的含量、土壤可溶性有机氮的来源和成分、土壤可溶性有机氮的迁移特征以及土壤可溶性有机氮的影响因素几个方面的研究进展进行综述,最后对未来土壤可溶性有机氮研究方向进行了展望。
Soil soluble organic nitrogen is an important part of soil nitrogen and also one of the most active factors in nitrogen cycle.Soil soluble organic nitrogen can not only be directly absorbed and utilized by plants,but also be utilized by soil microorganisms.Soil soluble organic nitrogen can move down with soil water,which causes agricultural non-point source pollution and other environmental problems.Hence many researchers have been diving into it.In this paper,we reviewed the study process of it from those fields,including the content of soil soluble organic nitrogen in different ecosystems,the source and composition of soil soluble organic nitrogen,the migration characteristics of soil soluble organic nitrogen and the influencing factors of soil soluble organic nitrogen.Finally,the future research fields are prospected.
