Abstract

The utility model discloses a dynamic in-situ research device for saline-alkaline heterogeneity, aiming at solving the problem that the existing research device cannot realize real-time monitoring of crops in saline-alkaline heterogeneity (saline-alkaline inconsistency exists in horizontal and vertical directions) fields. The device comprises a growth box, a vertical isolation plate, a transverse isolation layer, a drip irrigation pipe and a soil monitoring sensor, the growth box comprises an upper-layer box body and a lower-layer box body, the upper-layer box body and the lower-layer box body are arranged in a stacked mode, the upper-layer box body is not provided with a bottom face so that the upper-layer box body and the lower-layer box body can be communicated, and the transverse isolation layer is arranged between the upper-layer box body and the lower-layer box body. The vertical isolation plates are arranged in the upper-layer box body and the lower-layer box body and located on the two sides of the transverse isolation layer, the vertical isolation plates and the transverse isolation layer divide the growth box into a plurality of containing cavities used for containing soil, and the drip irrigation pipes and the soil monitoring sensors are inserted into the side faces of the growth box and located in the containing cavities. The saline-alkali plaque simulation device has the advantages of being simple in structure, convenient to operate and capable of truly simulating saline-alkali plaques.
