Description

本発明は、トマト苗に光を照射するための発光装置およびこれを用いたトマト苗の栽培装置に関する。   The present invention relates to a light emitting device for irradiating light on a tomato seedling and a tomato seedling cultivation device using the same.

従来から、植物の栽培においては、人工光によって、植物に必要な波長を有する光を効率よく照射して、植物の成長を促進することが行われている。植物の栽培に適した光には、赤色光と青色光とがある。赤色光は、特に光合成を促進する効果がある。青色光は、実や葉を大きく成長させる効果がある。   Conventionally, in plant cultivation, artificial light has been used to efficiently irradiate light having a wavelength necessary for plants to promote plant growth. Light suitable for plant cultivation includes red light and blue light. Red light is particularly effective in promoting photosynthesis. Blue light has the effect of growing fruits and leaves greatly.

例えば、特開２００２−２７８３１号公報（特許文献１）には、４００〜４８０ｎｍの青色光および６５０〜７００ｎｍの赤色光をそれぞれ生成するＬＥＤを用いた、植物育成用ＬＥＤ光源が、開示されている。このＬＥＤ光源によれば、青色光と赤色光との混光を植物に照射することができるので、植物の成長を促進することができる。   For example, Japanese Unexamined Patent Application Publication No. 2002-27831 (Patent Document 1) discloses an LED light source for plant growth using LEDs that respectively generate blue light of 400 to 480 nm and red light of 650 to 700 nm. . According to this LED light source, since the mixed light of blue light and red light can be irradiated to the plant, the growth of the plant can be promoted.

特開２００２−２７８３１号公報JP 2002-27831 A

ところで、トマト苗の成長においては、図４に示すように、一般に、本葉１０１が８段程度分化した後に、第１花房１０２の花芽が分化する。すなわち、トマト苗の第１花房１０２が着生する葉位（以下、「第１花房着生葉位」という）は、一般に、９段程度という高い位置である。   By the way, in the growth of tomato seedlings, as shown in FIG. 4, the flower buds of the first inflorescence 102 are generally differentiated after the main leaves 101 are differentiated by about eight stages. That is, the leaf position at which the first inflorescence 102 of tomato seedlings is grown (hereinafter referred to as “first inflorescence leaf-leaved position”) is generally a high position of about 9 stages.

本葉１０１が１段分化するには、一般に、約一週間を要する。それ故、第１花房１０２の花芽が分化するまでには、約９〜１０週間を要する。したがって、トマト苗の播種からトマトの実を収穫できるまで長期間を要していた。   Generally, it takes about one week for the true leaf 101 to differentiate into one stage. Therefore, it takes about 9 to 10 weeks for the flower buds of the first inflorescence 102 to differentiate. Therefore, it took a long time until the seeds of tomatoes could be harvested after sowing seedlings.

そこで、本発明の課題は、トマト苗の第１花房着生葉位を低い位置にするのに使用できる発光装置を、提供することである。   Then, the subject of this invention is providing the light-emitting device which can be used for making the 1st inflorescence stand position of a tomato seedling into a low position.

本発明者らは、上記課題の解決のために、発光装置の出射光の波長がトマト苗の第１花房着生葉位に与える影響について、研究を重ねた。その結果、出射光に含まれる青色光の相対発光強度値に対して、出射光に含まれる赤色光の相対発光強度値を所定の割合にすることで、トマト苗の第１花房着生葉位を低い位置にできることを見出し、この知見に基づいてさらに研究を重ね、本発明を完成させた。   In order to solve the above-mentioned problems, the present inventors have conducted research on the influence of the wavelength of the light emitted from the light emitting device on the first inflorescence leaf position of the tomato seedling. As a result, by setting the relative emission intensity value of the red light contained in the emitted light to a predetermined ratio with respect to the relative emission intensity value of the blue light contained in the emitted light, the first inflorescence setting position of the tomato seedling is determined. It was found that the position can be lowered, and further studies were made based on this finding, thereby completing the present invention.
