Wherein, the planting groove 100 can be made of stainless steel material, which not only has higher strength, but also has better corrosion resistance. The planting groove 100 is opened at the upper side so as to facilitate the planting substrate 110, the first filter layer 120, the drain layer 130 and the drain pipe 140 to be laid into the planting groove 100.

In one embodiment, the planting substrate 110 is used for planting plants, the planting substrate 110 is composed of light-weight and water-permeable components, and the planting substrate 110 includes one or more of mud, sand, rock wool, vermiculite, perlite, expanded ceramic, bark, sawdust, peat soil, bagasse, rice hulls, coal slag, mushroom slag, foamed plastic, and coconut husk substrate. In some embodiments, since the foundation base 10 is used in a temporary body exhibition, the planting base 110 is required to be light in weight, and preferably, the thickness of the planting base 110 is 200mm to 300 mm.

In one embodiment, the first filter layer 120 may be made of a flexible, light and thin material such as a filter screen or a non-woven fabric. The first filter layer 120 is disposed below the planting substrate 110, and not only can support the planting substrate 110 and prevent particles in the planting substrate 110 from infiltrating downwards, but also can filter water to make water in the planting substrate 110 infiltrate downwards.

In one embodiment, the drainage layer 130 may be a drainage plate, for example, a plastic drainage plate, which may be made of polystyrene (HIPS) or polyethylene (HDPE) as a raw material plastic bottom plate through stamping, and the plastic drainage plate includes a plate body and conical bosses, ribs, or hollow cylindrical protrusions, etc. disposed on the plate body, and may be a support structure formed by pressing a plastic plate through a male and female die and having a spatial three-dimensional structure, and the first filter layer 120 is supported by the conical bosses, ribs, or hollow cylindrical protrusions, etc., so that water seeped under the first filter layer 120 is drained between the conical bosses and finally drained away from the drainage pipe 140.

Therefore, the foundation base 10 in the above embodiment adopts a modular design, the foundation base 10 is designed into a plurality of modules, i.e. a plurality of planting modules, and different planting modules can be independently processed and assembled, thereby facilitating field construction. For the hard field 30, the planting groove 100 can be directly placed, and the first filtering layer 120, the drainage layer 130 and the drainage pipe 140 are arranged in the planting groove 100, so that the foundation 10 can be built in a field without drainage conditions, and the applicable field of the temporary theme exhibition device is increased.

In order to fully utilize the field, the planting groove 100 is obliquely arranged, namely the planting groove 100 is obliquely arranged relative to the ground plane; as shown in fig. 4, the planting groove 100 is supported by the support columns 200 such that the planting groove 100 is disposed obliquely.

The planting substrate 110 is distributed in the planting lattices 100A, and since the planting substrate 110 is in a small particle state, after the planting groove 100 is divided into the small planting lattices 100A by the fixed partition 300, the planting fixed partition 300 can block the planting substrate 110, and prevent the planting substrate 110 at a high position from slipping to a low position, so as to keep the thickness of the planting substrate 110 in the whole planting groove 100 uniform. Specifically, the planting lattices 100A are arranged at least from bottom to top along the inclined direction of the planting groove 100, or at least include a plurality of planting lattices 100A arranged along the horizontal direction, for example, the planting lattices 100A are arranged in a grid shape.

As shown in fig. 4, since the planting groove 100 is obliquely arranged, the water in the planting groove 100 flows downward along the bottom of the planting groove 100, and the drain pipe 140 is arranged at a position below the oblique planting groove 100, so that the water converged to the bottom enters the drain pipe 140 and is intensively drained away. Since the obliquely arranged planting groove 100 can play a role of converging downward intensively, the water converges downward and is discharged through the drain pipe 140 at the lower position of the planting groove 100.
