A reagent adding system, a sprinkler system, a light control system, an ultraviolet sterilization system, a cultivation system, a CO 2 regulation system, a temperature control system and a central control system are arranged on a box body of the device. The device can automatically regulate the temperature, CO 2 concentration and illumination and simulate the natural environment, can periodically add moisture for soil to ensure soil moisture content and simulate the soil in the nature, and can also quantitatively add pollutant reagents periodically to ensure a concentration of pollutants in a soil environment in which soil organisms are located in a test. The device is convenient to use and simple in operation, can be configured by scientific researchers according to own needs, decreases pollution of the pollutants, and has high scientific research and practical values.Drawings of Description 8 31 8 32 21 32 22 FIG.2 10 34 24 -23 42 72 _ 74 71 757 - --- 76 77 7 FIG. 1 Temperature control system ponent, ---- 82 Reagent adding system 2 Sprinkler system First solenoid valve 23Second sol-enoid 33 Central control system, 9vlve First movable 24 Coto oue ---- Second movable, 3 4 nozzle nozzle CO2 regulation system Light control system CO27 care-a 1 lrvoe 10 Control switch 4 cylinder ste'rilization system I2 Ultravi-olet L : LE re-le 4 CO2 sensor / 72 I sterilization lampLEreio 2 Gas pump -73resno FIG. 2 1
