Description

【発明の詳細な説明】 産業上の利用分野 本発明は水耕栽培方法に関する。[Detailed description of the invention] Industrial applications The present invention relates to a hydroponic cultivation method.

従来の技術 通常、水耕栽培では、トレー内に培養液を流しこの培養
液中に植物の根を泳がせ、この根から水分、養分。
Conventional technology Normally, in hydroponic cultivation, a culture solution is poured into a tray, and the roots of the plants are allowed to swim in this culture solution, and water and nutrients are absorbed from these roots.

酸素を吸収させている。この場合において2重要なこと
は根への酸素供給不足による根腐れの発生を防止するこ
とであり、この為に従来より種々な対策が取られている
。例えば、培養液中の溶存酸素量を増やすとか。
It absorbs oxygen. In this case, the second important thing is to prevent the occurrence of root rot due to insufficient oxygen supply to the roots, and various measures have been taken in the past for this purpose. For example, increasing the amount of dissolved oxygen in the culture medium.

培養液の液面を定期的に下げて根を空気中に曝すとか。The level of the culture solution should be lowered periodically to expose the roots to the air.

或いは根の大部分を培養液上の湿った空気中に位置させ
、この部分にルートマットを発達させる等の方法が取ら
れている。しかし、いずれにしてもトレー内に培養液を
流し、その培養液中に根の大部分或いは一部を浸漬させ
ていた。
Alternatively, a method is used in which most of the roots are placed in moist air above the culture solution and a root mat is developed in this area. However, in any case, a culture solution was poured into the tray, and most or part of the roots were immersed in the culture solution.

発明が解決しようとする問題点 ところがこの方法ではトレー内に培養液を流す為。The problem that the invention aims to solve However, with this method, the culture solution is poured into the tray.

トレーを所定の勾配に据付けねばならず据付作業が困難
であり、またトレーに大量の培養液を流すためトレーに
強度を必要とし、しかも培養液循環用のポンプ。
The tray must be installed at a predetermined slope, which makes installation work difficult, and the tray requires strength to flow a large amount of culture solution onto the tray, and a pump is required for circulating the culture solution.

There was a problem in that the equipment such as piping became larger and the equipment cost ended up increasing.

Means for Solving the Problems In order to solve the above-mentioned problems, the inventor of the present invention conducted various studies on plant growth in hydroponic culture and found the following points. In other words, although the roots (underwater plate) immersed in the culture solution grow rapidly in water, their surface is extremely smooth and does not contribute much to the absorption of water and nutrients. The root-ma-throat formed in the humid air above the culture medium has numerous small root hairs that extremely contribute to moisture and oxygen absorption, therefore.

We have found that the growth of the roots is primarily important for plant growth, and that the submersible plate is not necessary as long as the tip of the root is in contact with the culture solution and can absorb nutrients.

As shown in FIG. 2, a water-absorbing sheet material 2 is placed on the bottom of a tray 1, a culture solution is supplied to the sheet material to keep it constantly moist, and the top surface of the tray 1 is covered with a lid 3. A plant 4 is placed through the cover 3 so that the tip 5 of the root of the plant 4 comes into contact with the wet sheet material 2 and absorbs nutrients, and the contact between the sheet material 2 and the cover 3 is increased. This hydroponic cultivation method is characterized in that a root mat 7 is grown in a space 6.

Since the tray 1 used in the present invention is filled with only enough culture solution to wet the sheet-like material 2 therein, it does not require much strength, and the tray 1 can be manufactured inexpensively using a plastic film or a sheet. can. By supplying a small amount of culture solution to the sheet material 2 placed in the tray,
The tray should be placed so that the bottom surface of the tray is evenly wetted, and it does not have to be so thick that it will cause roots to become entangled. The sheet-like material 2 is a woven fabric or a non-woven fabric.

As a means for supplying the culture solution to the sheet-like material 2 and keeping it constantly moist, eight supply pipes (arranged on the bottom surface of the tray 1) are used. A double structure having a water supply channel 8A, a sprinkler channel 8B communicating with the water supply channel, and a small watering hole 8C is preferable because water can be uniformly supplied along the long unray 1.The supply pipe 8 is not shown in the figure. (It is not limited to the case where it is placed under the sheet-like material 2, as in the case where it is placed under the sheet-like material 2, but it may be placed at another place.) Further, the structure of the supply pipe 8 can also be changed as appropriate. The culture solution is supplied to the supply pipe 8G by a pump or a tank.

The lid 3 is provided so that the space 6 inside the tray 2 is maintained at a high temperature, and is separated from the sheet material 2 so as to leave enough space for the root mat 7 to grow on the sheet material 2. will be placed. A planting hole 9 is formed in this lid 3, and the plant 4 extends through the planting hole 9.

A pot 10 made of urethane or the like is inserted into the planting hole 9 to fix the plant 4 to the lid 3. Note that the lid 3 does not need to be formed as a separate member from the tray 1, but may be formed integrally with the tray. In other words, a part of the tray may function as a lid to keep the inside of the tray in a high temperature state. In addition, the shape of the lid is not limited to the flat one shown in the figure.
It can be changed as appropriate.

作用 供給管8から培養液がシート状材料2に供給され。action A culture solution is supplied to the sheet material 2 from the supply pipe 8 .

シート状材料2は常時湿潤状態に保たれる。この為。The sheet material 2 is kept constantly moist. For this reason.

The space above the sheet material 2 is maintained at a high temperature. Since the root tips 5 of the plants 4 are in contact with the wet sheet material 2, the roots absorb water and nutrients from the sheet material 2 and grow even if the roots are not immersed in water. Also.

根の成長に際し、根の先端は常に水を求めて伸びる為。When roots grow, the tip of the root always stretches out in search of water.

The tip of the root is always in contact with the sheet material 2. On the other hand, since the upper part of the sheet-like material 2 is kept at a high temperature, a humid plate having countless small root hairs grows in this part to form a root mat 7. This root mat 7 absorbs moisture and oxygen well. In this way, the roots receive nutrients and moisture without the lack of oxygen supply that occurs when the roots are immersed in a culture solution.

It can absorb oxygen and plants grow very well.

Effects of the Invention As described above, according to the present invention, plants can be successfully grown without immersing the roots in a culture solution. Therefore, there is no need to pour a large amount of culture solution into the tray, and it is only necessary to wet the sheet material in the tray with the culture solution, so the tray does not require great strength and the tray is easy to install.

The entire hydroponic cultivation apparatus used for carrying out the method of the present invention can be manufactured at low cost. Furthermore, since the amount of culture solution supplied may be small, operating costs can be reduced.
