土壤中气体的组成,不仅为土壤物理工作者注意,因其与土壤中微生物生命活动密切相关,故日益为土壤微生物学工作者所重视。有关如何采集土层中的气样,土壤物理学专著中,曾有过各种针钻式样的描述。但是近年来,随着气相色谱检测气样法的兴起,它以特具灵敏、快捷、分析用气样少,而受 The composition of gas in soil is not only paid attention to by soil physicists, but also paid more attention to by soil microbiology workers because it is closely related to the life activities of microorganisms in soil. There have been a variety of needle-drill-style descriptions of soil physics monographs on how to collect gas samples from soil layers. However, in recent years, with the rise of gas chromatography gas detection method, it is particularly sensitive, fast, less gas samples for analysis, and by
