The results obtained in the project of"The Quantitawe Estimate of Fixed Ammonium in the Nitrogen Cycle" are as follows.1) The balance sheet of ammonium fixation in the process of nitrogen transformation has been massured in the field. The release and fixation of ammonium N in clay minerals were significantly affected by the coexistence of sodium con.2)The relationship between release of fixed ammonium and nitrifiers was estimated in the nitrogen cycle of sorl.3)The axtagonism of K con. with ammonium fixation was discussed in the some sorls.4)The fixed ammonium would have an important role to continue the sustainable agriculture system in the close future.

在“氮循环中固定铵的定量估计”项目中得到的结果如下：1)实地测量了氮素转化过程中铵的固定资产负债表。黏土矿物中铵态氮的释放和固定受钠离子共存的显著影响。2)在土壤氮循环中，估计了固定铵态氮的释放与硝化物的关系。3)讨论了钾离子在某些土壤中与固铵的拮抗作用。(4)固定铵对未来可持续农业系统的延续具有重要作用。
