Description

技術の分野Technology field

本発明は、植物養液栽培装置に関するThe present invention relates to a plant hydroponic cultivation apparatus.

技術の背景Technology background

従来の、植物養液栽培システムにおいて、栽培養液は、栽培プランター内養液の水位(水深)は排水口の高さで決まり、排水口の高さを調整することにより、一定の高さで管理されていた。
栽培プランターに勾配をつけて流れを早くしても、栽培目的の植物に対し、植物の根(毛根、水根)を経由して、栄養素の養分が吸収されており、栽培プランターの養液中に常に根が浸かった状態で栽培されているので、イモ類、根菜類、薬草類の栽培は困難であった。
噴霧式養液栽培技術でも、ごぼう、人参、芋など、植物本来の形状が出来ずに毛根状態になり、栽培植物の形体が出来なかった。
イモ類、根菜類、薬草類の栽培期間中は、従来の養液栽培技術では、排水口の高さを調整しないと植物の根が常に養液の中に浸っている状態であり成長が出来なかった、成長を促す為には、常に根が養液に浸かる状態を回避するか、排水し栽培作物の根圏の酸素供給環境が必要であり、適度な水分も必要である為に、土耕栽培の団粒構造環境を養液栽培プランター内に構築する必要がある。イモ類、根菜類、薬草類の地下系植物養液栽培において、養液の中に、根が浸って,腐り、栽培が困難であった。以上の問題を解決する手段である。

In the conventional plant nutrient solution cultivation system, the cultivation nutrient solution is determined at a certain height by adjusting the height of the drain port, and the water level (water depth) of the nutrient solution in the cultivation planter is determined by the height of the drain port. It was managed.
Even if the cultivation planter has a gradient and speeds up the flow, the nutrients are absorbed through the plant roots (hair roots, water roots) to the plant intended for cultivation, and it is in the nutrient solution of the cultivation planter. Therefore, it is difficult to cultivate potatoes, root vegetables and medicinal herbs.
Even with spray-type hydroponics technology, burdock, carrots, cocoons, etc. were not able to form the original shape of the plant and became a hair root state, and the shape of the cultivated plant could not be formed.
During the cultivation period of potatoes, root vegetables and medicinal herbs, with conventional hydroponic cultivation techniques, plant roots are always immersed in the nutrient solution unless the height of the drainage is adjusted. In order to promote growth, it is necessary to avoid the state where the roots are always immersed in the nutrient solution, or to drain the cultivated crops in the rhizosphere oxygen supply environment, and since moderate moisture is also required, the soil It is necessary to build a nodule structure environment for cultivation in a hydroponic planter. In the underground plant nourishing culture of potatoes, root vegetables and medicinal herbs, the roots were soaked in the nourishing solution and rotted and difficult to grow. It is means for solving the above problems.

In the hydroponics method, the present invention uses the siphon principle to reproduce the rhizosphere environment (aggregate structure) close to soil culture in the hydroponics planter by implementing intermittent water supply and full drainage immediately. It is a method to do.
It is possible to cultivate potatoes, root vegetables and medicinal herbs by constructing a rhizosphere environment close to soil cultivation by the hydroponics method. When it is necessary for the cultivated plant, the nutrient solution is sent to the cultivation planter at irregular intervals, and the drainage is carried out at the same time as the water is full. It is done within. The nutrient solution in the nutrient solution storage tank is pumped to the cultivation planter, the nutrient solution level of the planter rises, the nutrient solution in the planter reaches the top of the siphon, and at the same time the air in the siphon trough is exhausted. The siphon building is filled with nutrient solution. At this point, the nutrient solution in the cultivation planter is drained to the bottom of the siphon by the principle of siphon, and the water level in the planter is The water level drops to the height of the bottom water intake, the nutrient solution in the cultivation planter is drained, the surface water around the root, the water retention capacity of the cultivation medium is lost, the next nutrient solution water supply is not necessary, water supply extension This is a possible intermittent nutrient solution management method.
The highest level of nutrient solution in the planter is determined by the height of the top of the siphon bowl, and the bottom of the nutrient solution in the planter is determined by the height of the water inlet of the siphon bowl, so the top of the siphon bowl The maximum water level and the minimum water level of the cultivation planter and nutrient solution can be set by changing the height of the water intake of the siphon bowl. By making it removable, various sizes can be prepared and exchanged according to the growth of cultivars and plants.
By changing the shape of the flexible siphon bowl without changing the siphon at the top and bottom of the nutrient solution in the planter, the highest water level and the lowest water position can be changed to any height with the flexible siphon bowl. I can do it.
By using a culture medium with water retention capacity, it is possible to extend the nutrient solution supply interval.
In the cultivation planter, the water supply timing can be set by a timer and a hygrometer in the planter. As an example, when potatoes are cultivated, at the time of germination, water is supplied once every 12 hours. Water supply once every 3 days, water supply once a week during the harvest period, and optional water supply, drainage, maximum water level, and minimum water level can be set to any height depending on the cultivation item. By becoming. The effect of the present invention is to provide a cultivation environment for potatoes, root vegetables, and medicinal herbs, which has been provided with a rhizosphere environment close to soil cultivation and has been impossible to grow conventionally.

発明の効果Effect of the invention

間欠式養液栽培なので、土耕栽培に近い栽培作物に根圏の環境提供が出来る。
脱着式サイフォンで任意に養液の給水、排水の高さが調整できる。
一つの栽培プランターにおいて、サイフォン菅の本数、内径の変更により排水速度の調整が可能である。
フレキシブル構造のサイフォンにより、任意の形状にすることにより、栽培プランター内の最頂水位位置、栽培プランター内の最低水位位置を任意の高さに、設定することが出来る。
栽培プランター内の養液をサイフォンの原理で給水、排水ができるので、電磁バルブ、水位センサー等、高価で高度なシステムが必要なく、植物工場投資コストが抑えられる。
作物に必要なときに、栽培プランター内に養液が供給され、栽培プランター内の養液がサイフォンの最頂部に到達すると同時に、サイフォンの最下部まで短時間で排水されるので、土耕栽培に近い根圏環境が再現できる。
栽培プランター内に常時養液無いので、NFT方式、DFT栽培方式と比較して、プランター荷重が掛からない事により構造を簡素化できる。
Since it is an intermittent hydroponic culture, it can provide a rhizosphere environment for cultivated crops close to soil cultivation.
The height of the nutrient water supply and drainage can be adjusted arbitrarily with the removable siphon.
In one cultivation planter, the drainage speed can be adjusted by changing the number and the inner diameter of siphon ridges.
By making an arbitrary shape with the siphon having a flexible structure, the highest water level position in the cultivation planter and the lowest water level position in the cultivation planter can be set to arbitrary heights.
Since the nutrient solution in the cultivation planter can be supplied and drained by the principle of siphon, expensive and sophisticated systems such as electromagnetic valves and water level sensors are not required, and the investment cost of plant factories can be reduced.
When it is necessary for the crop, nutrient solution is supplied into the cultivation planter, and the nutrient solution in the cultivation planter reaches the top of the siphon and drains to the bottom of the siphon in a short time. The near rhizosphere environment can be reproduced.
Since there is no regular nutrient solution in the cultivation planter, the structure can be simplified by not applying a planter load as compared with the NFT method and the DFT cultivation method.
