Investigation on Emission of Nitrous Oxide by Aseptic Soybean Plant

The emission of nitrous oxide is not only a way of nitrogen loss in ecological system of agriculture, it is also a contamination source of increasing nitrogen oxide concentration in the atmosphere. This paper reports the analysis of gas chromatographic determination of N2O on the soybean plant and its different four organs-root, stem, leaf and cotyledon under strict aseptic condition. The results showed ,hat they all are able to emit nitrous oxide.
