Car-based soil nutrient detect near-infrared spectroscopy technology and automatic sampling devices

The present invention provides a vehicle-based soil nutrient testing and automatic sampling device near infrared spectroscopy, the apparatus comprising a road wheel mounted with a mobile platform and a control box provided on the mobile platform, including the introduction of further provided mobile platform soil soil storage means and means provided in the bottom of the ground-breaking means and the optical system of the mobile platform, provided at the top of the control box provided at the control box and a GPS spectrometer, IPC, and a controller. The present invention is easy to operate, the entire spectral acquisition, recording, cluster analysis, a plurality of representative soil samples collected during a controlled and continuous like, polluting the entire testing process green, non-destructive testing system for continuous monitoring of large fields; the present invention is not only to reduce testing costs, but also can improve the prediction accuracy of the model.
