Experimental device for screening saline-alkaline tolerance of liana

The invention provides an experiment device for screening saline-alkaline tolerance of liana, and relates to the field of plant growth experiments. The experiment device for screening the saline-alkaline tolerance of the liana comprises a test box, a water distribution box is arranged on the rear surface of the test box, a distribution pipe is arranged on the upper surface of the water distribution box, a placing device is arranged in the test box, and a placing block is arranged in the placing device. The water distribution box is arranged, and a plurality of cavities are formed in the water distribution box, so that saline-alkaline water with different concentrations can be contained, saline-alkaline screening of different concentrations can be conveniently conducted on the liana in the water distribution box, the relation between the saline-alkaline concentration and the survival rate is obtained, and the optimal saline-alkaline concentration for liana survival is conveniently obtained; by arranging a plur
