Abstract
Description
本発明は、植物の生体状態の判別方法および判別装置に関するものである。 The present invention relates to a method for discriminating the biological state of a plant and a discriminating device.
植物は光を好み、光合成を行って太陽光などのエネルギーを生態維持のための糖分などに変換する。特に赤色系および青色系の色を得ることでそこから光エネルギー変換を行い、糖質に炭酸ガスを固定化していく（例えば、特許文献１〜３を参照）。このことから、全波長の自然光を植物に当てると、比較的必要としない緑色系の光を反射するため、我々には植物が緑色に見える。 Plants like light and perform photosynthesis to convert energy such as sunlight into sugar for maintaining ecology. In particular, by obtaining red and blue colors, light energy conversion is performed from the colors, and carbon dioxide gas is immobilized on carbohydrates (see, for example, Patent Documents 1 to 3). From this, when natural light of all wavelengths is applied to a plant, it reflects a relatively unnecessary greenish light, so that the plant looks green to us.
植物はこのように緑色に見えてしまうため、内部では光合成を積極的に行っているのか、光合成を行わない状態なのかは外観からは判別しにくい。殆ど光合成が行われない状態になったときに養分が不足している状態であれば、徒長が起きたり、葉色が黄変するなどの変化が起きる。この段階まで進むと、植物内の生理上は既にエネルギー不足状態がかなり続いている状態となっていて、もとの元気のいい状態まで回復させるためには相当の時間や施肥、温度や光などの条件を整えるなどの対処が必要となる。場合によってはこれらの対策を講じても既にエネルギー不足が強く影響してしまい、植物個体の生命を維持することができないことも起きうる。 Since plants look green in this way, it is difficult to tell from the outside whether they are actively photosynthesizing or not. If nutrients are insufficient when photosynthesis is almost non-existent, changes such as legginess and yellowing of leaf color occur. At this stage, the physiology of the plant is already in a state of considerable energy shortage, and it takes a considerable amount of time, fertilization, temperature, light, etc. to restore the original healthy state. It is necessary to take measures such as adjusting the conditions of. In some cases, even if these measures are taken, the energy shortage has already had a strong effect, and it may not be possible to sustain the life of the individual plant.
そのため、植物に対して、黄変や徒長など生体の状態を容易に判別できる状態を示す前に、その個体が十分な栄養を有しているかどうかということを判別することが重要となってくる。 Therefore, it is important to determine whether or not the individual has sufficient nutrition before showing the plant a state in which the state of the living body such as yellowing or legginess can be easily determined. ..
一般的にはこのような場合、その個体の葉や根などの生体を一部採取し、分析によってその状態を測ることが必要となる。しかし、採取してから分析結果が得られるまでには日単位の相応時間が必要となり、リアルタイムに生体の状態を把握することができない。さらに、生体には傷を付けることからそこから細菌類等に汚染されるおそれもあり、観葉系であれば美的な問題を生じることになる。 Generally, in such a case, it is necessary to collect a part of the living body such as leaves and roots of the individual and measure the state by analysis. However, it takes a considerable amount of time on a daily basis from the time of collection until the analysis result is obtained, and it is not possible to grasp the state of the living body in real time. Furthermore, since the living body is damaged, there is a risk of being contaminated by bacteria and the like, which causes an aesthetic problem if it is a foliage system.
このため、生体に対して採取等による傷を付けずに、非接触で生体のエネルギー状態を把握する技術が求められている。可視光以外の赤外や紫外領域の反射量を把握する方法で、それらを解析する技術も提案されている（例えば、特許文献４を参照）。 For this reason, there is a demand for a technique for grasping the energy state of a living body in a non-contact manner without damaging the living body by collection or the like. A technique for analyzing the amount of reflection in an infrared or ultraviolet region other than visible light has also been proposed (see, for example, Patent Document 4).
しかし、上記の可視光以外の赤外や紫外領域の反射量を把握する方法で、それらを解析する技術では、専用の機器が必要であったり、得られたデータを解析するプロセスが必要など、非接触で管理することはできるものの、ある程度の時間が必要であり、即時判断の材料としては使いづらい。 However, the technology for analyzing the amount of reflection in the infrared and ultraviolet regions other than the above-mentioned visible light requires a dedicated device or a process for analyzing the obtained data. Although it can be managed in a non-contact manner, it requires a certain amount of time and is difficult to use as a material for immediate judgment.
本発明は、上記に鑑みてなされたものであって、植物の生体状態をリアルタイムで判別することができる植物の生体状態の判別方法および判別装置を提供することを目的とする。 The present invention has been made in view of the above, and an object of the present invention is to provide a method for discriminating a biological state of a plant and a discriminating device capable of discriminating the biological state of the plant in real time.

In some cases, it is characterized in that it is determined that energy is not required.

The present invention is not limited to this embodiment.
（本発明の基本原理）
まず、本発明の基本原理を説明する。
本発明は、植物の吸収しやすい光スペクトルに着目してなされたものである。すなわち、赤色系の単色光を発光する光源からの光と、青色系の単色光を発光する光源からの光を混合した混合光を植物に当てると、その植物からの反射光の反射率は植物生態（生体状態）によって異なる。吸収する植物生態であれば、これらの混合光は植物に吸収されるため反射光の強度が低下し、人の目には黒く見える。一方、吸収状態ではない植物生態であれば、反射光の強度が低下せずよく反射するため、人の目には明るく見える。混合光は赤紫色系に見えるので、葉の表面などが、明るい赤紫色に見える。
(Basic Principle of the Present Invention)
First, the basic principle of the present invention will be described.
The present invention has focused on an optical spectrum that is easily absorbed by plants. That is, when a mixed light obtained by mixing light from a light source that emits red monochromatic light and light from a light source that emits blue monochromatic light is applied to a plant, the reflectance of the reflected light from the plant is the plant. It depends on the ecology (biological condition). In the case of plant ecology that absorbs, these mixed lights are absorbed by plants, so the intensity of reflected light decreases and it looks black to the human eye. On the other hand, if the plant ecology is not in an absorbed state, the intensity of the reflected light does not decrease and is reflected well, so that it looks bright to the human eye. Since the mixed light looks reddish purple, the surface of the leaves looks bright reddish purple.
自然光の下では同じ緑色に見えている植物でも、暗所下でこの混合光を当てると、明暗がはっきりと現れてくる。屋内であれば、暗室下でこれらの植物に対して混合光を与えればよく、屋外であれば、外光が当らないように箱等によって外光を遮断して暗室状態とするか、夜間の観察によって、当該明暗を判別することができる。 Even plants that look the same green under natural light can clearly see the light and darkness when exposed to this mixed light in the dark. If it is indoors, mixed light may be given to these plants in a dark room, and if it is outdoors, the outside light may be blocked by a box or the like to prevent the outside light from shining, or the plant may be in a dark room state at night. By observing, the light and dark can be discriminated.
混合光を当てることで、明色に見える植物は、積極的な光吸収および合成を行いたいと欲している状態と判別でき、成長段階であったり、より養分や光を当てることが必要であるということがわかる。一方、暗色に見える植物は、すでに養分が十分に生体内に蓄積されている状態と判別でき、これ以上の積極的な施肥や光などの供給は必要ないということがわかる。 By shining mixed light, plants that look bright can be identified as wanting to actively absorb and synthesize light, and it is necessary to shine more nutrients and light at the growth stage. You can see that. On the other hand, it can be determined that a plant that looks dark has already sufficiently accumulated nutrients in the living body, and it can be seen that no more active fertilization or supply of light is required.
このことから、本発明によれば、植物生態の状態をリアルタイムに把握することができ、必要とする植物個体には積極的な成長促進の管理を施し、必要としない（エネルギー飽和状態の植物）個体については、最低限の光や養分等の供給でよいということになる。 From this, according to the present invention, the state of plant ecology can be grasped in real time, and the plant individuals who need it are actively managed to promote growth and do not need it (plants in an energy saturated state). For individuals, the minimum supply of light and nutrients is sufficient.
（植物の生体状態の判別装置）
次に、本発明に係る植物の生体状態の判別装置の実施の形態について説明する。
図１に示すように、本実施の形態に係る植物の生体状態の判別装置１０は、暗所下で、赤色系の光と青色系の光を混合した混合光Ｂを植物Ｐ（図の例では葉）に当てる光照射手段１２と、植物Ｐからの反射光Ｒの強度を検出する反射光強度検出手段１６と、植物Ｐの生体状態を判別する判別手段１４とを備える。
(Device for determining the biological state of plants)
Next, an embodiment of an apparatus for discriminating the biological state of a plant according to the present invention will be described.
As shown in FIG. 1, the device 10 for determining the biological state of a plant according to the present embodiment uses a mixed light B, which is a mixture of red light and blue light, in a dark place as a plant P (example of FIG. 1). The leaf) is provided with a light irradiation means 12, a reflected light intensity detecting means 16 for detecting the intensity of the reflected light R from the plant P, and a discriminating means 14 for determining the biological state of the plant P.
光照射手段１２は、赤色系の光を発出する赤色系光源と、青色系の光出を発する青色系光源とを備えており、各光源からの光を混合した混合光Ｂを生成し、生成した混合光Ｂを植物Ｐに照射する。光源は、いかなる様式の光源でもよいが、様々な波長の光を発出できるＬＥＤ光源などが好ましい。光源から発出する赤色系、青色系の光の波長としては、それぞれ概ね４５０ｎｍ付近、６５０ｎｍ付近の波長が特に望ましいが、本発明はこれに限るものではない。 The light irradiating means 12 includes a red-based light source that emits red-based light and a blue-based light source that emits blue-based light, and generates and generates mixed light B in which light from each light source is mixed. The mixed light B is irradiated to the plant P. The light source may be any type of light source, but an LED light source capable of emitting light of various wavelengths is preferable. The wavelengths of the red and blue light emitted from the light source are particularly preferably around 450 nm and around 650 nm, respectively, but the present invention is not limited to this.
反射光強度検出手段１６は、植物Ｐからの反射光Ｒの強度（明暗の度合い）を検出するものであり、例えば、反射光Ｒによる所定の観察位置の照度を検出する照度センサなどの光センサで構成することができる。 The reflected light intensity detecting means 16 detects the intensity (degree of brightness) of the reflected light R from the plant P, and is, for example, an illuminance sensor such as an illuminance sensor that detects the illuminance at a predetermined observation position by the reflected light R. Can be configured with.
判別手段１４は、検出した反射光Ｒの強度に基づいて、植物Ｐの生体状態を判別するものである。この判別手段１４は、あらかじめ設定した強度（明暗度）に対して反射光Ｒが明るい場合に、エネルギーが必要な状態と判別し、反射光Ｒが暗い場合に、エネルギーが不要な状態と判別する。具体的には、反射光強度検出手段１６で検出した反射光Ｒの強度が所定の閾値以上であるときは、その植物Ｐは、積極的な光吸収および合成を行いたいと欲している状態と判別する。この状態は、成長段階であったり、より養分や光を当てることが必要な状態に相当する。一方、反射光強度検出手段１６で検出した反射光Ｒの強度が所定の閾値未満であるときは、その植物Ｐは、すでに養分が十分に生体内に蓄積されている状態と判別する。この状態は、これ以上の積極的な施肥や光などの供給が不要な状態に相当する。 The discriminating means 14 discriminates the biological state of the plant P based on the intensity of the detected reflected light R. The discriminating means 14 determines that energy is required when the reflected light R is bright with respect to the preset intensity (brightness), and determines that energy is not required when the reflected light R is dark. .. Specifically, when the intensity of the reflected light R detected by the reflected light intensity detecting means 16 is equal to or higher than a predetermined threshold value, the plant P is in a state of wanting to actively absorb and synthesize light. Determine. This condition corresponds to the stage of growth or the condition requiring more nutrients and light. On the other hand, when the intensity of the reflected light R detected by the reflected light intensity detecting means 16 is less than a predetermined threshold value, the plant P is determined to be in a state in which nutrients are already sufficiently accumulated in the living body. This state corresponds to a state in which no more active fertilization or supply of light or the like is required.
図２は、植物Ｐに混合光Ｂを照射した際の植物Ｐの表面の画像の一例である。（１）は、光量不足で光を欲している状態、（２）は、光量が十分に与えられている状態を示している。これらの画像は、自動露光調整するカメラで撮影した画像であるため、反射光Ｒの明暗が判別しにくいが、目視では明らかに図２（２）が白く（赤紫色）、（１）が黒く見えた。このように、反射光Ｒは目視でも容易に判別することができる。 FIG. 2 is an example of an image of the surface of the plant P when the plant P is irradiated with the mixed light B. (1) shows a state in which the amount of light is insufficient and desires light, and (2) shows a state in which a sufficient amount of light is given. Since these images are images taken by a camera that adjusts the automatic exposure, it is difficult to distinguish the brightness of the reflected light R, but visually, FIG. 2 (2) is clearly white (purple red) and (1) is black. Looked. In this way, the reflected light R can be easily discriminated visually.
上記の構成の動作および作用について説明する。
暗所下において、光照射手段１２から混合光Ｂを植物Ｐに当てる。続いて、反射光強度検出手段１６で植物Ｐからの反射光Ｒの強度を検出し、検出した強度に基づいて判別手段１４で植物Ｐの生体状態を判別する。この結果、反射光Ｒの強度が所定の閾値以上の場合（明るい場合）は、エネルギーが必要な状態と判別し、所定の閾値未満の場合（暗い場合）は、エネルギーが不要な状態と判別する。こうすることで、植物Ｐの生体状態が、エネルギーが必要な状態か否かをリアルタイムで簡易に判別することができる。
The operation and operation of the above configuration will be described.
In a dark place, the mixed light B is applied to the plant P from the light irradiation means 12. Subsequently, the reflected light intensity detecting means 16 detects the intensity of the reflected light R from the plant P, and the discriminating means 14 determines the biological state of the plant P based on the detected intensity. As a result, when the intensity of the reflected light R is equal to or higher than a predetermined threshold value (bright), it is determined that energy is required, and when it is less than the predetermined threshold value (dark), it is determined that energy is not required. .. By doing so, it is possible to easily determine in real time whether or not the biological state of the plant P is a state requiring energy.
また、本実施の形態によれば、オンデマンド型の光供給植物育成施設などの植物を活用する施設に有用である。効率のよい維持管理が可能となるので、施設の維持管理費のコストダウンを図ることができる。 Further, according to the present embodiment, it is useful for facilities that utilize plants, such as on-demand type light supply plant growing facilities. Since efficient maintenance is possible, it is possible to reduce the maintenance cost of the facility.
