Carbon‐13 (¹³C)‐labelled plant material forms the basis for experiments elucidating soil organic carbon dynamics and greenhouse gas emissions. Quantitative field‐scale tracing is only possible if plants are labelled homogeneously in large quantities. By using a laser spectrometer to automatically steer the isotopic ratio in the chamber, it is possible to obtain large amounts of homogeneously labelled plant material.

激光光谱技术在步入式生长室中引导植物材料的13C标签

碳13（¹³ C）标记的植物材料构成了阐明土壤有机碳动力学和温室气体排放的实验的基础。仅当植物被大量均匀地标记时，才可能进行定量的田间规模追踪。通过使用激光光谱仪自动操纵室内的同位素比率，可以获得大量均质标记的植物材料。
