Description

TECHNICAL FIELD The present invention relates to a method for cultivating a plant, which can effectively cultivate the plant in a dry area or a desert area with extremely low water retention capacity. is there.

“Prior art and its problems” In dry areas and desert areas with extremely low water retention capacity, artificially forming green belts and effectively cultivating vegetables and fruits are not the same as the conventional method. However, it was difficult because water vaporized and penetrated a lot. This is extremely difficult in terms of technology and cost, because the wider the scale, the more it promotes phenomena such as evaporation loss and salt concentration. Not only that,
It was not easy to manage the fertilizer so that it would be evenly adjusted to the physiological conditions of the crop.

The present invention has been made paying attention to such a point, and in a dry area or a desert area with extremely low water retention capacity,
It is an object of the present invention to provide a plant cultivation method capable of effectively cultivating a plant.

“Means for Solving Problems” In order to achieve the above-mentioned object, the present inventor has conducted diligent research,
By supplying the nutrient solution directly to the root hair of the plant without supplying it to the plant through the soil, it is possible to minimize the loss due to water infiltration and evaporation, making it possible to create dry areas and desert areas with extremely low water retention capacity. Even in this case, they have found that plants can be cultivated extremely effectively, and have reached the present invention.

That is, the present invention, vertically burying the terminal device made of biscuit material or open-cell plastic having fine capillary water-permeable holes in the soil vertically, position the plant above the terminal device in the upper part, It is characterized in that the nutrient solution is constantly supplied from the connected nutrient solution supply pipe to the terminal device so as to be in a saturated state, the root hair of the plant is entangled with the terminal device, and the nutrient solution is directly supplied to the root hair of the plant.

In short, the present invention, by directly entwining the root hair in the ground with the terminal device, enables the water to be supplied to the plant without excess or deficiency due to the osmotic pressure of the root hair. Utilizing the absorbency of, keep the terminal equipment saturated with nutrient solution at all times,
The gist of the invention is to make it possible to effectively grow plants in arid areas and desert areas with extremely low water retention capacity by minimizing evaporation loss of nutrient solution.

[Examples] Next, the present invention will be described with reference to the drawings.

FIG. 1 is a schematic diagram for explaining an embodiment of the present invention.

First, the terminal device 2 made of unglazed wood is vertically embedded in the soil of a field where plants are cultivated. Then, the vegetable 3 is positioned close to above the terminal device 2. Then, the nutrient solution is supplied from the nutrient solution supply pipe 1 connected to the terminal device 2, and the terminal device 2 is constantly saturated with the nutrient solution.

In this way, the root hairs 4 of the vegetables 3 tend to absorb the nutrient solution and become entangled with the terminal device 2 as shown in the figure.

The water permeable hole of the terminal device 2 is constantly filled with the nutrient solution from the nutrient solution supply pipe 1, and the root hairs 4 of the plant absorb the nutrient solution from the surface of the terminal device 2. The root hair 4 of the plant is
Since the soil is pushed away and entangled in the terminal device 2 to absorb the nutrient solution, the loss of the nutrient solution leaching from the outer periphery of the terminal device 2 into the soil is extremely small.

The terminal device 2 is made of an oval biscuit material or open-cell plastic, and the inside may be filled or may have a cavity.

By making the supply pressure of the nutrient solution from the nutrient solution supply pipe 1 to the terminal device 2 constant, the terminal device 2 is always saturated, and the nutrient solution is supplied just enough to meet the physiological condition of the plant. be able to.

When cultivating a plant 3 in the form of a straight root, as shown in FIG.
The terminal device 2 may be formed into a cylindrical shape having a required length that matches the root of the plant 3, the upper and lower ends thereof may be closed with stoppers, and the other configurations may be configured in the same manner as the embodiment of FIG. 1 and cultivated.

From the seedling to the growth and the harvest, the nutrient solution can be properly supplied with the fertilizer management by remote scanning, and the optimum amount can be always supplied.

As shown in FIG. 2, the nutrient solution supply pipe 1 may be supplied with the nutrient solution from the main pipe 5. By configuring in this way, even in a large field or long extension,
The nutrient solution can always be supplied effectively depending on the pipe diameter and head design.

[Effect of the Invention] As described above, according to the present invention, by directly entwining the root hair in the ground with the water permeable terminal device, it is possible to supply water to the plant without excess or deficiency due to the osmotic pressure of the root hair. In addition to being able to do so, it is possible to keep the terminal equipment saturated with the nutrient solution at all times due to the absorptive property of the water permeable terminal equipment due to the capillarity, and minimize the loss of penetration of the nutrient solution into the soil. Therefore, the plant can be effectively cultivated in the dry area or the desert area where the water retention capacity is extremely low.
