Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) The present invention relates to a culture shelf mainly used for tissue culture of plants, and aims to mass-produce high-quality cultured seedlings at low cost and efficiently. To do.

(Prior Art) For tissue culture of plants, the small plant pieces excised so far are placed in a large number of transparent glass containers individually containing a medium containing sugars, and this is equipped with a light irradiation device. The culture work was performed side by side in a closed chamber.

(Problems to be solved by the invention) However, in the case of the above-mentioned conventional culture technique, heat generation by an electric bulb used as a light source in the culture chamber or a large number of fluorescent lamps causes various harmful effects.

That is, if the light source is brought closer to the plantlets, the light intensity can be increased and the photosynthetic effect can be increased. There is no choice but to install them at separate positions and to supplement the amount of insufficient light due to this by increasing the number of light sources.

As a result, it is necessary to significantly increase the volume of the culture chamber,
In addition, the additional power source will increase the electricity bill, resulting in higher cost, and the problem of growth inhibition of plantlets due to the temperature rise in the entire culture room remains.

Therefore, in order to control the temperature in the culture chamber, it is inevitable that the cost will increase due to the further increase of the electricity charge due to the installation of the cooling device.

Further, there is a problem that it is difficult to control humidity and carbon dioxide concentration in the culture chamber.

(Means for Solving the Problems) The present invention solves the above-mentioned problems of the conventional technique, makes the culture chamber compact and significantly reduces the cost, and facilitates the control of the humidity and the carbon dioxide concentration. It is intended to promote the growth of plant pieces, and specifically, a top plate and a shelf plate, or a culture space with an open side surface where a space is formed between the upper and lower shelf plates with a certain interval. A duct space formed by bridging a mesh shelf with a predetermined space between the top plate or the upper shelf plate of the culture space, a light source unit suspended on the mesh shelf, and a side surface of the culture space, Or a light reflection plate formed on the side surface and the lower shelf plate surface,
The present invention relates to a plant tissue culture shelf, which comprises a ventilation fan that blows air into the duct space or exhausts air from the duct space, and in which the culture space is provided in several vertical stages.

(Operation) The plant tissue culture shelf may be used as it is,
Most of them are used by being installed in the culture room.

A transparent glass container such as a test tube containing plant pieces is arranged on a shelf, and light is emitted from a light source toward the plant pieces in the transparent glass container for a certain period of time.

The light from the light source directly irradiates the plantlets, and also indirectly reaches the plantlets by being reflected by the light reflecting plate formed on the side surface of the culture space or the side surface and the lower shelf plate surface.

When the air taken in from the outside is blown into the culture chamber through the mesh shelf from the duct space by the ventilation fan, or when the air in the culture chamber is exhausted outside from the mesh shelf through the duct space, it is placed near the light source. The generated heat is sent out of the culture room.

(Embodiment) The specific contents of the present invention will be described below with reference to an embodiment shown in the drawings. 5 is a culture space, 7 is a duct space, 9 is a light source, 11 is a light reflection plate, and 8 is a ventilation fan. Show.

The culturing space 5 is formed between the frames 1 and 1 by vertically installing a top plate 3 and a shelf plate 4 at regular intervals, and the duct space 7 is the top plate 3 of each culturing space 5 or the above. It is formed by installing a mesh shelf 6 having good ventilation between the shelf board 4 and the shelf board 4 located at a predetermined interval.

Further, the light source unit 9 is constructed by suspending a plurality of fluorescent tubes under the mesh shelf 6 or suspending a high-pressure sodium lamp (not shown).

The light reflecting plate 11 is freely attached to the frame 1 through the hinge 10 so as to be able to shield at least half of the surfaces opened on the left and right side surfaces of the culture space 1 described above.

The ventilation fan 8 is rotatably mounted by a motor (not shown) near the window 8a opened in the lateral direction of the duct space 7.

In addition, 2 is a caster.

Further, in the above embodiment, the light reflection plate 11 is provided in each culture space 5.
, But is not necessarily limited to this, and is also attached to the lower side of the culture space 5 via a hinge mechanism or by a fastening means other than the hinge mechanism, or only on the side surface of the culture space. Instead, the lower shelf board surface may be formed by attaching a light reflecting film.

Also, the number of the culture spaces 5 installed is not limited to that of the embodiment, and any number of stages may be used as long as it is two or more. Moreover, each shelf board 4 has a frame 1 depending on the kind of plantlets to be cultured.
It is more preferable that the volume of the culture space can be freely changed along the vertical direction and the volume of the culture space can be freely changed.

In the above configuration, the reflection angle of the light reflection plate 11 is adjusted as necessary according to the relative distance between the light source 9 and the plant piece placed on the shelf 4, and the light emitted to the side is adjusted. Are reflected toward the small plant piece.

In addition, if it is not needed, it is not an obstacle if it is placed along the frame 1.

Further, one or more of the above-mentioned culture shelves are placed in a culture chamber (not shown), and an air conditioning unit for controlling the temperature and humidity in the culture chamber and a carbon dioxide controller for institutional horticulture are attached outside the culture chamber. The temperature, humidity, carbon dioxide concentration, and the light intensity of the light source that illuminates the culture space of the culture shelf are controlled by a microcomputer, and a pattern of temporal change suitable for each type of plantlet is created. It is more effective if the is designated to the microcomputer for efficiency.

(Effects of the Invention) The present invention has a duct space above each culture space through a mesh shelf, and since the light source unit is hung on the mesh shelf, the heat generated from the light source unit can be efficiently generated in the culture space. It can be discharged to the outside, and the light source can be brought closer to the placing shelf of the plant piece by that much, so the amount of light that irradiates the plant piece at an accelerated rate increases, and the amount of illumination of the light source decreases by that amount. In addition, the cost can be reduced due to a significant reduction in the amount of electric power used, and the culture efficiency can be improved due to the reduction in the space, as compared with the case where a conventional cooling device is attached.

Also, by installing a light reflection plate on the side surface or the side surface and the bottom surface of the culture space, it is possible to indirectly irradiate scattered light, which was conventionally wasted, toward the plantlets, so that the light irradiation efficiency is improved. It can be remarkably improved, and photosynthesis of plants can be promoted to further reduce costs.
