土壤氮素矿化研究进展

Research Progress of Soil Nitrogen Mineralization

总结了土壤中氮素矿化的研究成果,阐述了影响土壤氮矿化作用的因素,其中温度、湿度均对氮矿化量、矿化率有影响,且二者存在明显交互作用,除此之外土壤的理化性质及外来物质如肥料也会影响土壤的氮矿化过程。论述了土壤氮矿化的各种研究方法,并对有关方法和指标的效果进行了比较,以期为选择合适的土壤供氮能力的研究方法提供依据。

This paper summarized research results of the soil nitrogen mineralization and expounds the factors which influence soil nitrogen mineralization,including temperature and humidity influence on nitrogen mineralization content and rate,and the interaction between the two was obvious.Besides,physical and chemical properties of soil and foreign substances,such as fertilizer,will also affect the soil nitrogen mineralization processes.It discussesed various methods of the soil nitrogen mineralization,and compared the involved methods and indexes,in order to provide evidence when choose the suitable study method of soil nitrogen supply capacity.At the end of the article,the author put forward the prospect of research on soil nitrogen mineralization.
