DETAILED DESCRIPTION OF INVENTION

[0025] With reference to FIG. 1, an open plant cultivation device 1 includes a container 10, a medium layer 20, a plant 30, and a separation layer 40.

[0026] The container 10 has an opening, a bottom surface, an inner side surface 11, a sterile accommodation space 12, and an open growing space 13. The inner side surface 11 is formed from the periphery of the bottom surface. The sterile accommodation space 12 is defined by the bottom surface and the inner side surface 11. The open growing space 13 is defined by the inner side surface 11, and is adjacent to the sterile accommodation space 12 and communicates with the opening of the container 10.

[0027] The medium layer 20 is disposed in the sterile accommodation space 12 of the container 10. The medium layer 20 has an upper surface opposite the bottom surface of the container 10.

[0028] The plant 30 is disposed in the sterile accommodation space 12 of the container 10 and disposed in the open growing space 13 of the container 10. A part of the plant 30 is immersed in the medium layer 20.

[0029] The separation layer 40 is disposed in the sterile accommodation space 12 of the container 10 and disposed on the upper surface of the medium layer 20. The separation layer 40 is adjacent to the inner side surface 11 of the container 10. The sterile accommodation space 12 and the open growing space 13 are isolated from each other by the separation layer 40. That is, the medium layer 20 is surrounded by the container 10 and the separation layer 40 to separate the medium layer 20 from the exterior and to prevent the medium layer 20 from being contaminated.

[0030] Specifically, the material of the container 10 is endurable for sterilization. A material of the medium layer 20 is adjustable according to the species of the plant 30. A material of the separation layer 40 has a low curing temperature (lower than 70° C.).

[0031] With reference to FIGS. 1 and 2, the method for preparing the open plant cultivation device 1 was conducted by the steps as follows. First, the container 10 was put in a sterile environment. At this step, the sterile accommodation space 12 and the open growing space 13 communicated with each other before the medium layer 20, the plant 30, and the separation layer 40 were disposed in the container 10.

[0032] Then a medium colloid was prepared by a conventional adequate method according to the species of the plant 30, and then adequate amount of the medium colloid was fed into the sterile accommodation space 12 of the container 10.

[0033] In particular, the material of the medium layer 20 was composed of water, an inorganic salt, and an organic compound. Specifically, the major elements of the inorganic salt included carbon, hydrogen, oxygen, nitrogen, phosphate, potassium, sodium, magnesium, calcium, sulfur, chlorine, and ferric; the minor elements of the inorganic salt included boron, manganese, zinc, molybdenum, cobalt, copper, and iodine. The organic compound included hydrocarbon, vitamin, inositol, adenine, amino acid, a plant growth regulator, and agar.

[0034] Subsequently, the plant 30 was disposed in the container 10, and then a part of the plant 30 was immersed in the medium colloid.

[0035] In another embodiment, the plant 30 was disposed in the container 10 after the container 10 was put in the sterile environment. Then, the medium colloid was fed into the sterile accommodation space 12 of the container 10 and the part of the plant 30 was immersed in the medium colloid.

[0036] Then the medium colloid was solidified into the medium layer 20.

[0037] Finally, a layer of jelly wax (curing temperature: 60° C., with flowability at room temperature) was disposed on the medium layer 20. The layer of jelly wax acted as the separation layer 40. The thickness of the separation layer 40 was 0.5 cm.

[0038] By means of the installation of the separation layer 40, the sterile accommodation space 12 and the open growing space 13 were isolated from each other by the separation layer 40. That is, the sterile accommodation space 12 and the open growing space 13 did not communicate with each other anymore. Therefore, the medium layer 20 would not be contaminated by the exterior environment and the plant 30 would have the open growing space 13 communicating with the exterior environment. Furthermore, the layer of jelly wax used in the embodiment had flowability at room temperature, so the growth of the plant 30 would not be hindered by the separation layer 40.

[0039] In conclusion, according to the open plant cultivation device and the method for preparing the open plant cultivation device, the plant can live in the open growing space. Therefore, the problems in the closed plant cultivation device are overcome and the plant can be viewed, touched, or smelled. Due to the medium layer, the cultivator does not have to fertilize and cultivate the plant. Owing to the medium layer not communicating with the exterior, the possibility of the medium layer being contaminated by the exterior environment is decreased. Besides, the plant can be transplanted without acclimation after fully absorbing the medium layer.
