Description

TECHNICAL FIELD The present invention relates to a mobile irradiation device for growing plants, and more specifically, to a light source having a wavelength close to that of sunlight for insufficient photosynthetic energy during crop cultivation. Repeatedly move the irradiating device equipped with the above along the row of cultivated plants while supporting it at an arbitrary height above the ground, and mainly irradiate deep into the leaf group from a short distance laterally of the cultivated plant to efficiently supplement the insufficient photosynthetic energy. However, the purpose of this is to promote and enhance its growth and also to strengthen the resistance to pests and diseases that occur on the underside of leaves, bark, etc. The present invention relates to a mobile irradiation device for growing plants, which has a similar irradiation mechanism.

[Conventional technology]

Irradiation devices for conventional plant cultivation, mainly those having a fixed or movable light source that irradiates light rays from above or diagonally above the cultivated plant occupies the mainstream, as is seen in, for example, electric-chrysanthemum greenhouse cultivation. There is.

[Problems to be Solved by the Invention]

When using a fixed type irradiation device as described above, since the irradiation direction of the light beam is constant, a large number of lamps are required to supplement the photosynthetic energy over the entire cultivation plant row, and the fruit tree It was found that the light energy required for growing cultivated plants such as vegetables and petals is deep in the leaf group, and in particular, it has a practical difficulty in efficiently reaching the back side of the leaf. Further, even if it is a mobile type, since light rays are radiated from above or obliquely above, the light energy necessary for growing a cultivated plant cannot be efficiently delivered to the leaf group, especially to the back side of the leaf. . Therefore, when the above-mentioned movable or fixed irradiation device is used, there is a problem in the irradiation efficiency of photosynthetic energy.

The present invention is to provide a mobile irradiation device of lateral close proximity low position irradiation type capable of solving the decrease in the irradiation efficiency of photosynthetic energy, which has been a problem in the conventional fixed irradiation device for growing plants. Is.

[Means for Solving the Problems]

As a means for solving the above problems, the present invention, between each of a plurality of cultivated plant rows, a tension wire extended along the cultivated plant rows,
Each of the overhead lines between the cultivated plants, in the lateral close proximity of the cultivated plants via a suspension support member such as a pulley, and of a wavelength close to the sunlight suspended movably at a relatively low position on the ground An irradiation device equipped with a photosynthetic light source, is stretched in a continuous ring so as to surround a row of cultivated plants along the tension line, and a traction line fixedly locking the tension support member of the irradiation device, (EN) A mobile irradiation device for growing plants, which comprises a drive device that reciprocally moves a traction line at an appropriately set speed.

[Action]

At the desired height above ground on the side of the cultivated plant, a tension wire is extended between the rows of the cultivated plant, and the irradiation equipment suspended and supported by the tension line is used along the cultivated plant row by using the traction line. By reciprocating at a moderate speed and irradiating photosynthetic energy from a relatively short distance to the lateral side of the cultivated plant, it is difficult for ordinary rays to reach the inside of the leaf group, especially between the leaves, to the back of the leaf. It allows the photosynthetic energy to reach and also promotes photosynthesis due to the "light-spotting effect".

〔The invention's effect〕

By using the device of the present invention, a light ray having a wavelength close to that of a sun ray is irradiated to the inside of a leaf group of a cultivated plant, especially to the back side of the leaf, which is usually hard to reach a ray, from multiple directions. Therefore, the light energy necessary for growing the crop, which is said to be insufficient for greenhouse cultivation, is effectively supplied. Thus, not only the yield of the harvested product but also the sugar content, color development and the like are improved, and the resistance to pests and the like is also increased.

In particular, at a distance close to the lateral side of the cultivated plant row, and because the light source can be moved relatively downward, the leaves of the cultivated plant that are difficult to reach the sunlight, especially the wavelength close to the sunlight to the back side of the leaves. It is possible to reach a ray of light with a high temperature, and this lower position is suitable for photosynthesis because of its high CO ₂ concentration, and this moving irradiation light is fragmented by numerous leaf pieces, twigs, etc. of cultivated plants. It becomes "chopped light", which exhibits a so-called chopped light effect, and promotes photosynthesis.

In addition, expensive equipment investment, which was a problem with conventional equipment that fixedly arranged a large number of irradiation equipment for each row of cultivated plants, was avoided, and at the same time a great result is expected to improve the energy saving effect. To be done.

Further, the mobile irradiation device for plant cultivation according to the present invention is cheaper than other methods and is easy to install or remove at the site because of its simple structure, and during harvesting work, between cultivated plant rows Therefore, the work environment can be widened by removing the tension line and the traction line.
