The invention discloses a soil column sectional type intelligent temperature control system, and relates to the field of soil moisture and solute vertical migration characteristic research. The temperature of the soil column is controlled in the mode that the modularized temperature control rings are nested on the outer layer of the soil column in a segmented mode, two flow guide holes are formed in the side face of each modularized temperature control ring and connected with a flow guide pipe, the flow guide pipes are connected with a constant-temperature cold/hot water tank, and the temperature of the temperature control rings is adjusted by adjusting the cold/hot water inlet proportion through electromagnetic valves; the temperature change condition of the vertical section of soil in different regions and different seasons can be simulated, the temperature change of the soil column at different heights is realized, and the migration rule of soil moisture and solute under different temperature gradients is
