| 摘 要： | N2O是一种重要的温室效应气体。目前全球的N2O源／汇估算不平衡，源大于汇，可能存在重要的未知源。过去一直认为生物源N2O仅由土壤中的微生物过程所产生，但近年来研究表明微生物之外的其它生物，如植物，也参与N2O的排放或吸收过程。大量的研究结果显示：植物释放N2O的速率不仅与植物的种类、器官及所处的生理阶段有关，而且与其自身的NO3^-含量和所处的环境中的二氧化碳浓度、光照强度、温度等有关。本文综合报道了植物排放N2O研究的主要进展。

| Abstract: | The sources and sinks of N2O, one of the major greenhouse gases in the atmosphere, are not well characterized and unbalanced. It was previously thought that only soil microbial process produced N2O, However, in recent years, some studies have led to a clue that plant may play an important role in N2O emission and uptake.N2O emission from plant is controlled by species and growing stages of plants, nutrient supply, illumination and CO2 concentration. |
