1. Field of the Invention
This invention relates to a culture apparatus, more particularly to a plant culture apparatus.
2. Description of the Related Art
With promotion of plant cultivation techniques, a number of ornamental plants can be currently planted in a closed plant culture apparatus. Generally, as shown in FIG. 1, the conventional closed plant culture apparatus 1 includes a transparent culture container 11 and a cover 12 to air-tightly close the culture container 11. A culture medium 10 such as agar is disposed in the culture container 11, and roots 21 of the ornamental plant 2 are planted in the culture medium 10. Hence, the plant 2 is able to obtain nourishment from the culture medium 10 and carry out photosynthesis utilizing the light penetrating through the transparent culture container 11.
However, the inner surface of the culture container 11 is usually adhered with moisture produced from volatilization of the culture medium 10 and photosynthesis of the plant 2. The inner surface of the culture container 11 is then fogged by the moisture adhered thereto, so that the plant 2 cannot be seen clearly from the outside, and that the ornamental value of the plant culture apparatus 1 is decreased. Additionally, the nourishment included in the culture medium 10 is limited, and the plant 2 tends to wilt due to lack of nourishment after being planted in the plant culture apparatus 1 for a period of time. Hence, the period for the plant 2 to be admired is relatively short.
