Remote Sensing Technology-Reflected Signals of Farmland Soil
To optimize the characteristics of vegetable thinning, use the remote sensing technology to measure the reflectivity of the planting soil after the moisture changes. ZEISS CORONA PLUS (old model CORONA) is used to measure the amount of reflected radiation in the field. The reflectivity of the soil at 850nm wavelength is between 10% and 74%, while the topsoil varies from 21% to 32%. It is known that the reflectivity of the soil is non-linear exponential with the soil moisture.
The experiment is to use Zeiss CORONA 400-1700nm, connect an external OMK diffuse reflectance measurement probe with fiber optic cable, use BaSO4 for calibration reference, and the window passes through an optical glass (23x32mmx10mm height).
