A wood longitudinal compression test device comprises a mold, a supporting assembly and a pressurizing mechanism, the mold is defined by four splicing assemblies, the splicing assemblies are movably connected to form a mold inner cavity suitable for the required radial size, the side face of a test piece is defined and fixed, and the pressurizing mechanism longitudinally compresses the test piecein the mold inner cavity through the supporting assembly. The inner diameter of the inner cavity of the mold is adjusted according to different movable connecting positions of the splicing assemblies,so that the mold is suitable for test pieces with different specifications and sizes; longitudinal compression of test pieces of different specifications is achieved through mold limiting; a supporting assembly and a pressurizing mechanism are arranged, the pressurizing mechanism longitudinally compresses the test piece in the inner cavity of the mold through the supporting assembly, and the compression amount is calculat
