[0033] The soil three-parameter measurement method and system proposed by the present invention are described in detail as follows in conjunction with the accompanying drawings and embodiments.
[0034] The soil three-parameter measurement method and system of the present invention take the ADR principle as the theoretical basis, calculate the water content of the soil by measuring the stable alternating voltage formed on the probe and the high-frequency coaxial cable, and calculate the conductance of the soil through the formula The temperature of the contact surface between the probe and the soil is obtained through the temperature sensor set in the probe, and finally the soil conductivity is calibrated according to the temperature to complete the measurement of the three parameters of the soil. The method and system can quickly complete the measurement of soil sample water content, electrical conductivity and temperature within 2-4 seconds, and has strong resistance to the i...
