Agricultural irrigation mainly refers to irrigation operations carried out in agricultural cultivated areas. Agricultural irrigation methods can generally be divided into traditional surface irrigation, ordinary sprinkler irrigation and micro irrigation. Traditional surface irrigation includes furrow irrigation, furrow irrigation, flood irrigation and flood irrigation, but this type of irrigation method often consumes large water and has low water utilization, which is a very unreasonable type of agricultural irrigation. In addition, ordinary sprinkler irrigation technology is a more common irrigation method in China’s agricultural production. However, the water utilization efficiency of ordinary sprinkler irrigation technology is also not high. Modern agricultural micro-irrigation technology includes micro-sprinkler irrigation, drip irrigation, seepage irrigation, etc. These irrigation technologies generally have good water-saving performance and higher water utilization than traditional irrigation models, of course, there are some drawbacks. The soil moisture transmitter is to monitor the moisture of the soil, bury the entire soil moisture transmitter in the soil of the root of the crop to monitor the moisture of the root soil, the soil moisture transmitter will transmit the detected data signal to the main controller, and the main controller determines the control state. “If the humidity is too high”, the irrigation is stopped; “If the humidity is too low”, the solenoid valve connected to the water source is controlled by photoelectric isolation and relay. The soil moisture transmitter can communicate with the host computer through the communication interface, and can monitor the system operation status in real time or analyze the historical data. Soil moisture transmitter can also be called: soil moisture transmitter, soil moisture transmitter. It is mainly used to measure soil volume water content, soil moisture monitoring and agricultural irrigation and forestry protection. At present, commonly used soil moisture transmitters are FDR type and TDR type, that is, frequency domain type and time domain type. More popular is FDR type frequency domain reflectometer is an instrument for measuring soil moisture, it uses the principle of electromagnetic pulse, according to the frequency of electromagnetic wave propagation in the medium to measure the apparent permittivity (ε) of the soil, so as to obtain soil volume water content (θv), FDR has the advantages of simple and safe, fast and accurate, fixed-point continuous, automated, wide range, less calibration and so on. It is a recommended instrument for soil moisture measurement.
