【摘要】 <正> 氧化亚氮（N₂O）是大气的微量成分之一。多年的测定表明,它在大气中的浓度正以0.2％左右的年增长率在增加。N₂O具有“温室效应”并能催化大气同温层中臭氧保护层的破坏,从而可能带来全球性生态环境的重大变化而受到世人的极大关注。各国科更多还原

【Abstract】 Studies of the different pathways of N Joss from plant-soil system are highly important for increasing the efficiency of soil N and decreasing the environmental contamination. This paper is the first report on the N₂O emission from some plants （e. g. soybean, maize, rice and alder）, and points out the emission rates of N₂O being related to the plant species or their organs. Possible implications of the N₂O emission from plants are discussed.更多还原
