| titleOfInvention | Laser spectrum multipoint detection system and method for ammonia volatilization flux of farmland |
| abstract | The invention discloses a farmland ammonia volatilization flux laser spectrum multipoint detection system, which is characterized in that a detection system is provided with a set of system host machine and a plurality of in-situ detection probes, the in-situ detection probes are grouped, each group of probes synchronously works, and multipoint comparison analysis and detection are realized through multipoint synchronous detection in the same group; different groups of probes are detected in a time-sharing sequence, so that the use efficiency of the detection system is improved; the detection sensitivity is improved by adopting a dual-radio-frequency modulation spectrum technology and combining a long-optical-path absorption cell and a distributed optical fiber network; the method is particularly suitable for detecting the ammonia volatilization flux of the farmland in a small area, does not need gas sampling, and meets the research and application requirements of multipoint comparison detection analysis of the ammonia volatilization flux of the farmland. |
