植物の栽培方法及び植物の栽培装置Plant cultivation method and plant cultivation equipment
　本発明は、トマト等の植物の栽培する植物の栽培方法及び植物の栽培装置に関するものである。 The present invention relates to a method for cultivating plants such as tomatoes and a plant cultivation apparatus.
　トマトの栽培方法には、温床に苗を仕立ててこれを露地に植え付ける土耕から、植物工場的な生産が可能な水耕まであり、例えば水耕として養液栽培方法が提案されている。 Cultivation methods for tomatoes range from soil cultivation in which seedlings are prepared on a hotbed and planted in the open field to hydroponics that can be produced in a plant factory. For example, a hydroponic cultivation method has been proposed as hydroponics.
　この養液栽培方法として、特許文献１には、水平断面形状が略Ｄ字形に形成される溝を長手方向に２列に配列してなる栽培用トレイの前記各溝に、２５０ｍｌ前後の培地（土、ヤシガラ、ロックウール他）を入れ、トマトの苗を植付けた各培地に潅水養液を供給する技術が開示されている。 As this hydroponic cultivation method, in Patent Document 1, about 250 ml of a medium (about 250 ml) is provided in each groove of a cultivation tray in which grooves formed in a substantially D-shaped horizontal cross section are arranged in two rows in the longitudinal direction. A technique is disclosed in which soil, coconut husk, rock wool, etc.) are put in and a irrigation nutrient solution is supplied to each medium in which tomato seedlings are planted.
　特許文献１に記載の技術において、従来の培地（土、ヤシガラ、ロックウール他）は、比較的保水性がよいため、潅水養液を植物が必要な潅水量より１０～２０％多めに潅水して、余剰液は雑菌が繁殖しやすいので廃液として処分するのが一般的であった。また弱酸性土壌の方が植物の生育にはよいとされているため潅水養液は弱酸性のPH調整を行っていた。 In the technique described in Patent Document 1, the conventional medium (soil, coconut husk, rock wool, etc.) has relatively good water retention, so the irrigation nutrient solution is irrigated 10 to 20% more than the irrigation amount required by the plant. Therefore, it was common to dispose of the surplus liquid as waste liquid because various germs easily propagate. In addition, since weakly acidic soil is said to be better for plant growth, the irrigation solution was adjusted for weakly acidic pH.

　＜実施形態の作用及び効果＞
　ここで、従来の培地として一般的に用いられるロックウールと液肥の組み合わせでは、毎年培地の交換が必要になり、産業廃棄物として費用を要する。 <Actions and effects of embodiments>
Here, in the combination of rock wool and liquid fertilizer, which is generally used as a conventional medium, the medium needs to be replaced every year, which is costly as industrial waste.
　近年の培地として普及してきたヤシガラ培地と液肥の組み合わせでは、ヤシガラ培地が有機質で雑菌が繁殖により経年変化を生じるため、１～２年で培地の交換が必要になる。 In the combination of coconut husk medium and liquid fertilizer, which has become popular as a medium in recent years, the coconut husk medium is organic and secular variation occurs due to the propagation of germs, so it is necessary to replace the medium in 1 to 2 years.
　従来の高糖度トマト栽培では、液肥（水）を極力少なくして、果実が吸収する水分を少なくして糖度を上げるため、果実の生産量が少なくなる。 In the conventional high sugar content tomato cultivation, the amount of liquid fertilizer (water) is reduced as much as possible, the water absorbed by the fruit is reduced, and the sugar content is increased, so that the amount of fruit produced is reduced.
　本発明の実施形態の培地３で用いられるサンゴ砂礫では、経年変化しないアルカリ性で雑菌が繁殖しづらい特性を有しているので、交換の必要がない。 The coral gravel used in the medium 3 of the embodiment of the present invention has the property of being alkaline that does not change over time and making it difficult for germs to propagate, so that it does not need to be replaced.
　また、サンゴ砂礫の培地３に浸した後の液肥４では、雑菌が繁殖しづらい特性により、高糖度トマト栽培において、培地の使用年限を延長することができる。また、サンゴ砂礫の培地３に浸した後の液肥４では、極端な潅水制限を行う必要がないため、生産性を向上することができる。 In addition, in the liquid fertilizer 4 after being soaked in the coral gravel medium 3, the period of use of the medium can be extended in the cultivation of high sugar content tomatoes due to the characteristic that germs are difficult to propagate. Further, in the liquid fertilizer 4 after being soaked in the coral gravel medium 3, it is not necessary to perform extreme irrigation restriction, so that the productivity can be improved.
　また、実施形態に係る植物の栽培方法では、液肥４の雑菌が繁殖しづらい特性により、排液用の殺菌を行う設備を必要としない。 Further, the plant cultivation method according to the embodiment does not require a facility for sterilizing the drainage due to the characteristic that the germs of the liquid fertilizer 4 are difficult to propagate.
　さらに、本発明の実施形態で用いられるサンゴ砂礫の培地３に浸した後の液肥４では、カルシウムやマグネシウム等の多種類（７０種類）の必須ミネラルを豊富に含有しているため、生育時に微量要素としてトマトに吸収されて、非常に糖度が高いトマト（糖度８～１２度）が生産されるため、市場でニーズの高い高糖度トマトを高能率で生産できる。 Further, since the liquid fertilizer 4 after being immersed in the coral gravel medium 3 used in the embodiment of the present invention contains abundantly various (70 kinds) essential minerals such as calcium and magnesium, a trace amount at the time of growth is obtained. Since tomatoes with a very high sugar content (sugar content of 8 to 12 degrees) are produced by being absorbed by tomatoes as an element, high sugar content tomatoes, which are in high demand in the market, can be produced with high efficiency.
　さらに、使用するサンゴ砂礫の培地３も容器（栽培ベッド４２）のに詰め込む分だけでよいので、サンゴ砂礫の使用によるコストの増大を十分抑制できる。 Furthermore, since the coral gravel medium 3 to be used only needs to be packed in the container (cultivation bed 42), the increase in cost due to the use of coral gravel can be sufficiently suppressed.
　従って、本発明の実施形態に係る植物の栽培方法によれば、植物（トマト）の栽培にかかる費用を低減することが可能になる。 Therefore, according to the method for cultivating a plant according to the embodiment of the present invention, it is possible to reduce the cost for cultivating a plant (tomato).
　さらに、本発明の実施形態に係る植物の栽培方法によれば、制御盤５０により、温度、湿、日射量、培地（サンゴ砂礫）３の水分状況を管理し、定期的に、液肥４による灌水を行ことができるので、栽培コストを低減できる。 Further, according to the plant cultivation method according to the embodiment of the present invention, the control panel 50 controls the temperature, the humidity, the amount of solar radiation, and the water condition of the medium (coral gravel) 3, and periodically irrigates with the liquid fertilizer 4. Therefore, the cultivation cost can be reduced.
　潅水チューブ５により灌水された液肥４は、培地（サンゴ砂礫）３に十分いきわたり、多孔質のサンゴ砂礫の中まで浸透する。 The liquid fertilizer 4 irrigated by the irrigation tube 5 sufficiently permeates the medium (coral gravel) 3 and penetrates into the porous coral gravel.
　サンゴ砂礫は、粒状で通水性がよく、液肥４の余剰液は、不織布２７、ネット２６、不織布２５、波板２４の波を通過して排液溝８に流出する。この際、ＰＯフィルム（水耕用黒ポリプラスチックシート）２４は、ガター２の防水用としての機能を発揮し、ガター２の防水シートとして使用される。この後、液肥４の余剰液は、廃液として排液管９を通って養液循環槽６に回収する。これにより、液肥４のリサイクル活用が行えるので、清水、Ａ液、Ｂ液の使用量を抑制することが可能になり、植物の栽培コストを低減することが可能になる。 The coral gravel is granular and has good water permeability, and the excess liquid of the liquid fertilizer 4 passes through the waves of the non-woven fabric 27, the net 26, the non-woven fabric 25, and the corrugated plate 24 and flows out to the drainage groove 8. At this time, the PO film (black polyplastic sheet for hydroponics) 24 exhibits a function for waterproofing the gutter 2 and is used as a waterproof sheet for the gutter 2. After that, the excess liquid of the liquid fertilizer 4 is collected as waste liquid in the nutrient solution circulation tank 6 through the drainage pipe 9. As a result, the liquid fertilizer 4 can be recycled and utilized, so that the amount of fresh water, the liquid A, and the liquid B used can be suppressed, and the cultivation cost of the plant can be reduced.
　さらに、本発明の実施形態に係る植物の栽培方法によれば、排液溝８の容積を広くすることにより、栽培ベッド４２に勾配を付ける必要が無くなり、複数の栽培ベッド４２を水平となる高さで設置することが可能になり、培地（サンゴ砂礫）３内の水分率が均一になることにより、トマトが均一に生育するので、管理が容易になる。 Further, according to the plant cultivation method according to the embodiment of the present invention, by increasing the volume of the drainage groove 8, it is not necessary to make a gradient in the cultivation bed 42, and the height of the plurality of cultivation beds 42 becomes horizontal. It becomes possible to install the tomatoes in a uniform manner, and the water content in the medium (coral gravel) 3 becomes uniform, so that the tomatoes grow uniformly, which facilitates management.
