Abstract
Description
本件は、植物の発芽及び成長促進剤、部材、装置、並びに養液栽培方法に関する。 The present invention relates to a plant germination and growth promoter, a member, a device, and a hydroponics method.
植物の栽培は、一般に、播種、発芽、育苗、及び定植という過程を経ることで行われる。
その際、発芽においては、種子の１００％が発芽することは珍しく、植物の種類によって発芽率は様々である。
また、育苗段階及び定植段階においては、成長に時間がかかると、栽培期間が長期化し、栽培効率が低下する。
Cultivation of plants is generally carried out through the processes of sowing, germination, raising seedlings, and planting.
At that time, in germination, it is rare that 100% of the seeds germinate, and the germination rate varies depending on the type of plant.
In addition, in the seedling raising stage and the planting stage, if the growth takes time, the cultivation period becomes long and the cultivation efficiency decreases.
また、栽培の全過程を通じて雑菌などにより植物の成長が阻害される場合がある。
そこで、水耕栽培する際に雑菌が培地に付着することがあったとしても、植物を根腐れさせないようにするため、培地に光触媒担体層が形成されると共に、光触媒担体層に紫外線ライトガイドが配され、ライトガイドは、光触媒担体層内で側面から漏光する側面漏光型光ファイバで形成した水耕栽培装置が提案されている（特許文献１参照）。この提案の技術は、植物を根腐れを防ぐことを目的とする一方で、発芽率の向上や、成長の促進を目的とするものではない。
In addition, plant growth may be hindered by various bacteria during the whole cultivation process.
Therefore, even if miscellaneous bacteria may adhere to the medium during hydroponics, in order to prevent root rot of the plant, a photocatalyst carrier layer is formed in the medium, and an ultraviolet light guide is provided on the photocatalyst carrier layer. There has been proposed a hydroponic cultivation apparatus in which the light guides are arranged and are formed by side-face light leakage type optical fibers that leak light from the side faces in the photocatalyst carrier layer (see Patent Document 1). The proposed technique aims at preventing root rot in plants, but does not aim at improving the germination rate or promoting growth.

（植物の発芽及び成長促進剤）
本件の植物の発芽及び成長促進剤は、チタンアパタイトを含有し、更に必要に応じて、その他の成分を含有する。
(Plant germination and growth promoter)
The plant germination and growth promoter of the present invention contains titanium apatite and, if necessary, further contains other components.
＜チタンアパタイト＞
前記チタンアパタイトとは、カルシウムアパタイトの一部をチタンで置換した物質を意味する。前記チタンアパタイトは光触媒性能を有することが知られている。
<Titanium apatite>
The titanium apatite means a substance in which part of calcium apatite is replaced with titanium. It is known that the titanium apatite has photocatalytic performance.
前記チタンアパタイトは、水和物であってもよい。前記チタンアパタイトは、例えば、Ｃａ１０（ＰＯ４）６（ＯＨ）２で表されるカルシウムヒドロキシアパタイトにおけるカルシウムの一部がチタンで置き換わったＣａ９Ｔｉ（ＰＯ４）６（ＯＨ）２で表される。 The titanium apatite may be a hydrate. The titanium apatite is represented by Ca 9 Ti (PO 4 ) 6 (OH) 2 in which a part of calcium in calcium hydroxyapatite represented by Ca 10 (PO 4 ) 6 (OH) 2 is replaced by titanium, for example. It
なお、前記チタンアパタイトにおけるカルシウムとチタンとリンとの相互比率は、必ずしも上記組成に完全に合致する必要はない。例えば、Ｘ線回折で結晶相を調べた結果、アパタイト構造を示す回折パターンが得られ、ＸＰＳにより粉体の表面分析を行った結果、チタンアパタイトの金属成分であるＣａとＴｉとが検出できるものであれば、前記チタンアパタイトとして扱うことができる。また、アパタイトはイオン性の強い結晶であり、金属イオンの置換が容易なため、さまざまな元素を含有させることができる。したがって、Ｃａ，Ｔｉ以外の元素が含まれていても、チタンと、アパタイトの結晶構造とを有していれば、前記チタンアパタイトとして扱うことができる。 The mutual ratio of calcium, titanium and phosphorus in the titanium apatite does not necessarily have to completely match the above composition. For example, as a result of examining the crystal phase by X-ray diffraction, a diffraction pattern showing an apatite structure was obtained, and as a result of surface analysis of the powder by XPS, the metal components Ca and Ti of titanium apatite can be detected. If so, it can be treated as the titanium apatite. In addition, apatite is a crystal having a strong ionicity, and since it is easy to substitute metal ions, various elements can be contained. Therefore, even if it contains elements other than Ca and Ti, it can be treated as the titanium apatite as long as it has titanium and the apatite crystal structure.
前記植物の発芽及び成長促進剤は、前記チタンアパタイトの光触媒機能により、植物の種子の発芽を促すと考えられる。
即ち、前記チタンアパタイトが紫外線を吸収することで、前記チタンアパタイトが前記チタンアパタイトの周囲の物質を分解し、ラジカルを発生させ、前記ラジカルが植物の種子を刺激することで、発芽が促され、結果、発芽率が向上すると考えられる。
そのため、前記植物の発芽及び成長促進剤が植物の種子の発芽率を向上させるためには、前記植物の発芽及び成長促進剤、特に前記チタンアパタイトに紫外線が照射されることが好ましい。
It is considered that the plant germination and growth promoter promotes germination of plant seeds by the photocatalytic function of the titanium apatite.
That is, the titanium apatite absorbs ultraviolet rays, the titanium apatite decomposes the material around the titanium apatite, to generate radicals, the radicals stimulate the seeds of the plant, germination is promoted, As a result, it is considered that the germination rate is improved.
Therefore, in order for the plant germination and growth promoter to improve the germination rate of plant seeds, it is preferable that the plant germination and growth promoter, particularly the titanium apatite, is irradiated with ultraviolet rays.
また、前記植物の発芽及び成長促進剤は、前記チタンアパタイトのアパタイトにより、植物の成長を促すと考えられる。
前記アパタイトに含まれるリンやカルシウムは、植物の栄養分であるため、植物が前記アパタイトからリン及びカルシウムを吸収することで植物の成長が促進される。植物がリンを根から吸収する場合、安定なリン酸鉄やリン酸アルミニウムの状態では吸収できない。一方、植物の根が吸収しやすいリン化合物は、リン酸水素イオン（ＨＰＯ４ ２−）、リン酸二水素イオン（Ｈ２ＰＯ４ −）であり、これはリン酸石灰が水に溶解することで生成する。そして前記アパタイトもリン酸石灰構造を含むため、その点において、植物の根が前記アパタイトのリン及びカルシウムを吸収しやすいことで、前記植物の発芽及び成長促進剤による植物の成長の促進がなされるものと考えられる。
Further, it is considered that the plant germination and growth promoter promotes plant growth by the apatite of the titanium apatite.
Since phosphorus and calcium contained in the apatite are nutrients of the plant, the plant absorbs phosphorus and calcium from the apatite to promote the growth of the plant. When plants absorb phosphorus from the roots, it cannot be absorbed in the stable iron phosphate or aluminum phosphate state. On the other hand, phosphorus compounds that are easily absorbed by plant roots are hydrogen phosphate ion (HPO 4 2− ) and dihydrogen phosphate ion (H 2 PO 4 − ), which means that lime phosphate dissolves in water. Generate with. And since the apatite also contains a phosphate-calcium structure, in that respect, because the roots of the plant easily absorb the phosphorus and calcium of the apatite, germination of the plant and growth of the plant by a growth promoter are promoted. It is considered to be a thing.
前記植物の発芽及び成長促進剤は、水分散剤として用いられてもよい。
例えば、前記植物の発芽及び成長促進剤は、前記チタンアパタイトを含有する水分散剤であって、培地に散布して用いられる。
前記水分散剤における前記チタンアパタイトの含有量としては、特に制限はなく、目的に応じて適宜選択することができる。
The plant germination and growth promoter may be used as an aqueous dispersant.
For example, the plant germination and growth promoter is an aqueous dispersant containing the titanium apatite and is used by being sprayed on a medium.
The content of the titanium apatite in the water dispersant is not particularly limited and can be appropriately selected depending on the purpose.
前記植物の発芽及び成長促進剤が適用される植物としては、特に制限はなく、目的に応じて適宜選択することができ、例えば、葉菜類、薬草類などが挙げられる。
前記葉菜類としては、例えば、パクチー、ケールなどが挙げられる。
The plant to which the plant germination and growth promoter is applied is not particularly limited and may be appropriately selected depending on the intended purpose. Examples thereof include leaf vegetables and herbs.
Examples of the leaf vegetables include bakchee, kale and the like.
前記植物の種子は、暗発芽種子であってもよいし、光発芽種子であってもよいが、前記植物の発芽及び成長促進剤、特に前記チタンアパタイトに紫外線を照射する際に、種子にも紫外線を含む光が照射されるため、光発芽種子であることが好ましい。 The seeds of the plant may be dark germinated seeds or may be light germinated seeds, but when irradiating the germination and growth promoter of the plant, especially the titanium apatite with ultraviolet rays, the seeds are also Light-germinating seeds are preferable because they are irradiated with light including ultraviolet rays.

(Example 1)
<Hydroponics>
<< Sprouting >>
Germination of Pakchi was carried out. As the seeds of Pakchi, coriander made by Nakahara Seed Co., Ltd. was used.
The titanium apatite aqueous dispersion was obtained by dispersing 10 parts by mass of titanium apatite (TiHAP; manufactured by Taihei Chemical Industry Co., Ltd., PCAP-100) in 100 parts by mass of water.
A nursery tray (144 holes) was filled with a dedicated medium (Baidon, manufactured by Mitsubishi Chemical Agridream Co., Ltd.) containing rock wool granular cotton as a main component, and seeding holes were formed with a press plate. At that time, the titanium apatite aqueous dispersion was irrigated in advance in the medium to contain the titanium apatite in the medium. 4-5 seeds per cell were sowed by a sowing plate. Each tray was irrigated with 300 ml to 400 ml and germinated in a germination room (setting at 20 ° C.) (3 to 4 days). At that time, approximately 10 μW of UV light was applied to the seed-containing medium by a fluorescent tube. The germination rate was calculated from the ratio of germinated seeds to the total number of seed holes.
As a result, the germination rate was 95%.
＜＜育苗＞＞

A new culture solution was set in a cultivation block to be planted (a culture solution tank of 4 to 6 cultivation beds 500 L, one block was composed of a water supply / drainage system, and the bed group was divided into 10 to 16 blocks per 16a). The suitable planting period was when about 2 cm of two true leaves had grown. Prior to planting, the seedlings were pushed up using a seedling cutting board. The planting was performed by pinching the seedlings and dropping them into the planting holes of the planting panel. A root pot (in this example, the one in which the medium and the root were solidified) was supported on the bottom of the bed, and the seedlings became independent. In addition, titanium apatite remains when the titanium apatite aqueous dispersion is brined in the root pot medium. The number of plants was 45 holes per panel (1 × 0.6 m). The seedling pot was placed in a damp space and immediately started rooting. After 2 weeks, the seedlings were pulled out and the growth status (length, etc.) was confirmed.
As a result, the average length from the top of the root to the top of the leaf was 19 cm.
