Multi-layer soil water and nitrogen migration irrigation control and data acquisition system

The multi-layer soil water nitrogen migration irrigation control and data acquisition system comprises an organic glass soil column filled with experimental soil in a layered manner; the moisture temperature sensor is used for detecting moisture temperature of soil of different layers in the organic glass soil column; the irrigation device is used for irrigating soil in the organic glass soil column; the industrial personal computer is connected with a valve of the irrigation device, controls the irrigation water amount according to requirements, and collects and stores moisture temperature data and irrigation water amount data of soil of different layers in the organic glass soil column; the data collector is connected with the moisture and temperature sensor and the irrigation device water meter, and transmits the moisture and temperature data of the soil and the irrigation water volume data to the industrial personal computer through a serial communication module; the direct-current power supply is connect
