Description

Description: TECHNICAL FIELD The present invention relates to a plant growing method using a reflecting mirror and the reflecting mirror, and more particularly, to improving the irradiation of a plant with a solar ray in greenhouse cultivation or outdoor cultivation. The present invention relates to a plant growing method using a reflecting mirror that promotes the growing of a plant and its reflecting mirror.

[Conventional technology and its problems]

Conventionally, for appreciation plants, for example, carnations, etc., when cultivating this in a house, simply planting it on the growing floor of the house, in a house having a roof that substantially transmits light, the sun rays that pass through the roof are The plants can be enjoyed, and at the same time, the interior of the house is shut off from the outside at the time of daylighting to raise the temperature to a suitable temperature, thereby enhancing the effect of plant growth. In parallel with this, a heating system was installed to raise the temperature inside the house to compensate for the temperature rise inside the house during the sunshine season.

The sunlight rays necessary for plant growth (photosynthesis by chlorophyll) depended mainly on transmission from above the house.

In addition, it goes without saying that in open-field cultivation, strong sunlight from above can be directly received, but the outdoor temperature must be above a certain level, which is a seasonal limitation.

The present inventor has conducted the research on the causal relationship between the plant growth and the irradiation of the sun rays, and has obtained the following findings.

That is, the irradiation of the growing plants with sunlight is not only performed from above the plant to the leaves, but also from the back side of the leaves to be particularly effective for photosynthesis by chlorophyll, and the roots and roots. It is to help the roots and stems grow by directly irradiating the stalks close to the sun.

[Means and Actions for Solving Problems]

Based on the above findings, the plant growing method using the reflecting mirror according to the present invention is, as described in claim (1), a through hole through which the root P2 of the plant P containing soil and planted can be exposed to the outside. The upper floor 3A having the above is installed in the growing house 4 so as to be separated from the ground to form a space S between the upper floor 3A and the ground of the growing house 4, and the reflecting mirror 1 that reflects sunlight is provided above. The plant P is placed on the floor 3A to reflect the sun rays on the back side of the leaves of the plant P, and the reflector 1 is also placed under the upper floor 3A to arrange the stem P1 near the upper floor 3A and the upper part. Extend the soil of the floor 3A and reflect it so that the sun's rays hit the root P2 exposed from the through hole of the upper floor 3A,
Furthermore, the technical means of growing the plant P in the growing house 4 by reflecting the sun rays on the shaded portion generated in the growing house 4 by the reflecting mirror 1 hung from the ceiling 4B of the growing house 4 so as to hit the shade. I took it.

According to this, firstly, the sun rays can be applied to the back of leaves that are not normally exposed to the sun rays, the stem P1 at the base, and the root P2 exposed from the upper floor 3A. You can grow P1 and root P2, and you can make a nice flower.

Further, in addition to this, the reflecting mirror 1 hung from the ceiling 4B eliminates the stem portion in the growing house 4, and it is possible to grow plants uniformly in the whole growing house 4.

Other advantages of the present invention will be apparent from the description of the examples below.

〔Example〕

FIG. 1 shows an embodiment of a plant growing method using the reflecting mirror of the present invention, in which a reflecting mirror 1 for reflecting sun rays is placed on a bed 2 for growing a plant, and the plant P (here, , Carnation) was used to reflect the sunlight on the back side of the leaf and grow. Therefore, the reflecting mirror 1 is arranged between the stems of the cultivated plant P.

As shown in FIG. 1, the arrangement method of the reflecting mirror 1 is as follows.
A pillar 5 is erected on A to stand between the stems of the plant P, a net 6 is horizontally stretched between the pillars 5, and the reflecting mirror 1 is arranged on the net 6.

In this way, the reflecting mirror 1 is installed between the plants, and the rays of the sun are retroreflected from the bottom to the top to give the rays to the back side of the leaves. The plant grows upwards because the sun is right underneath. In addition, the stem becomes tough, the quality is good, and the special grade is high.

FIG. 2 shows a front sectional view of a plant growing method using the reflecting mirror of the present invention, which uses an upper floor 3A for accommodating soil and a plant growing bed 2 having a space S below it.

Here, with the reflection mirror 1 that reflects the sunlight, the stem portion P1 of the plant P near the upper floor 3A of the growing bed 2,
The root part P2 extending to the lower floor 3B and the petals are irradiated with sunlight to grow.

That is, by installing the reflecting mirror 1 toward the sun in the passage of the bed 2, the sun hits the part of the root where the rays of the sun did not reach until now, and the growth of the root can be enhanced.

FIG. 3 shows an example of the growing house 4 used in the present invention. In the inside of the growing house 4 in which the roof portion 4A and the wall surface 6 are made of a material (for example, transparent vinyl chloride) that substantially allows sunlight to pass through. In the method for growing a plant, a reflector 1 for reflecting a sun ray is reflected on a ceiling part 4B of the growing house 4 (the highest beam portion of the triangular roof in this embodiment) of the growing house 4. It is arranged in a hanging state along the direction of the ridge, whereby the irradiation of the sun rays to each part inside the growing house 4 is made uniform and the growing is performed. In particular,
In the inside of the growing house 4, since shade portions are moved and formed at various places as the irradiation direction of the sun changes, the reflection mirror 1 can uniformly illuminate such shades.

That is, by installing the reflecting mirror 1 in the shape of a strip in the center of the ceiling of the multi-storey vinyl house, it is possible to shut out the shade in the multi-storey building, and to evenly apply the sun's light heat to the entire facility.

Next, a preferred embodiment of the reflecting mirror 1 used in the plant growing method of the present invention will be described in detail.

(Experimental example) Illuminance test Greenhouse carnation Central building of a 5-story house Outside 1st time 80,000LUX 2nd time 92,000LUX Although the number of planted plants was small, the number of shipments could be doubled by using the reflector.

〔The invention's effect〕

According to the plant growing method of the present invention, the upper floor is installed in the growing house so that the upper floor having the through holes through which the roots of the plant planted and containing soil are exposed can be separated from the ground. A reflector that forms a space between the ground and the ground of the growing house and that reflects sunlight is placed on the upper floor to reflect the sunlight so that the back side of the leaf of the plant is exposed to the sunlight and below the upper floor. Also, a reflector is placed to extend the soil near the upper floor and the soil inside the upper floor so that the sunlight is reflected on the root exposed through the through hole in the upper floor. , Sunlight can be applied to the back of the leaves, the stems of the roots, the roots exposed from the upper floor, etc. that are not normally exposed to the sun, and it is possible to grow very solid stems and roots, and a splendid flower There is an advantage that can be attached.

Furthermore, since the reflectors hung from the ceiling of the growing house grow the plants in the growing house by reflecting the sun's rays so as to hit the shaded parts generated in the growing house, uniform plant growth can be achieved throughout the growing house. There is an advantage that it becomes possible.

In addition, by installing the upper floor having a through hole through which the roots of the plant planted and containing soil are exposed to the outside away from the ground, and installing it in the growing house, the upper floor and the ground of the growing house Since there is a space between them, the air on the soil on the upper floor is sufficiently spread out, and as mentioned above, a reflector can be installed below the upper floor to form stronger roots and stems. There is an advantage.
