Cultivation device based on saline-alkali soil improvement

The invention relates to the technical field of saline-alkali soil improvement, and particularly discloses a cultivation device based on saline-alkali soil improvement. The bearing box body is a rectangular box body of which the top and the bottom are designed in an open manner; the two pairs of containing cavities are formed in the vertical walls of the periphery of the bearing box body correspondingly, and the tops of the containing cavities are exposed out of the top surfaces of the vertical walls of the bearing box body. The two pairs of filter plates are respectively embedded in the outer walls of the peripheral vertical walls of the bearing box body, the outer side walls of the filter plates are exposed out of the outer surface of the bearing box body, and the inner side walls of the filter plates are exposed out of the inner surface of the accommodating cavity; the two pairs of partition plates are arranged in the two pairs of containing cavities respectively and divide the containing cavities into cry
