[0034] Example 1

[0035] Reference Figure 1-Figure 9 , is a soil spectrum generating device disclosed in the utility model, comprising a shell 1 with an open upper surface and a PC display terminal (not shown in the figure), a cover body 2 is installed on the upper surface of the shell 1 by bolts, and also comprises a core processor 3, a digital signal source 4, a sensor element 5, a base plate 6, an electric control unit 7, a shielding box 8, a directional coupler (not shown in the figure) and a filter (not shown in the figure) arranged inside the shell 1.

[0036] The digital signal source 4 is used to transmit and receive electromagnetic waves of different frequencies. The digital signal source 4 is fixed to the inner bottom wall of the housing 1 by bolts and connected to the sensor element 5 by a cable. The sensor element 5 is inserted into the soil sample to detect the change of electromagnetic wave characteristics caused by the polarization of metal ion elements.

[0037] It is worth mentioning that the digital signal source 4 emits electromagnetic waves to polarize the metal ions in the soil sample. Polarization is a concept in physics. It refers to the phenomenon of electric dipole moment generated by the separation of positive and negative charges in originally unpolarized substances under the action of an electric field. Polarization will cause the electric energy of the electromagnetic wave to be converted into the kinetic energy of the charge, thereby consuming the energy of the electromagnetic wave in this frequency band. Electromagnetic waves of different frequencies can stimulate the polarization of different media. For example, if the frequency band of ion polarization of a certain metal element is 0.75-1HZ, then the polarization of the element will occur in this frequency band, resulting in differences in the amplitude-frequency curve of this frequency band. The sensor element 5 thus detects the change in the electromagnetic wave characteristics caused by the ion polarization. When the electromagnetic wave emitted by the digital signal source 4 is transmitted to the sensor element 5 through a cable, reflection will occur. The reflected electromagnetic wave will carry the information of the change in the electromagnetic wave characteristics measured by the sensor element 5 and will eventually be received by the digital signal source 4.
