Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a hydroponic system for cultivating crops on pine trees inside a factory or the like.

[Prior Art] When cultivating crops indoors, it is important to control the temperature of the crops.

In conventional greenhouse cultivation, the entire room is heated and cooled.

[Problems to be solved by the invention] However, heating and cooling the entire room requires heating and cooling to reach every corner of a large room, which is wasteful and increases heating and cooling costs. The ratio of production costs to production costs was becoming high.

Therefore, the present invention eliminates the waste caused by the conventional method by providing local air conditioning to the crop area, thereby reducing heating and cooling costs.The present invention also makes it possible to supply nutrient solution in small quantities to improve the quality of crops. The aim is to improve growth.

[Means for Solving the Problems] The present invention is characterized by positioning pine trees with holes for planting crops at regular intervals in the longitudinal direction between a plurality of ventilation pipes arranged in parallel on a cultivation shelf. A groove for storing nutrient solution is provided below each pine, and a nutrient solution supply pipe for supplying nutrient solution to the crops planted in the pine is arranged above the center of each pine. .

[Operation] When a crop is planted together with a medium into a hole provided in a pine, the roots of the crop grow in the grooves below the pine. The nutrient solution is supplied to the crops by dropping it from the nutrient solution supply tube in the center of the pine to the roots of each crop. On the other hand, warm and cold air is supplied to the crops from the ventilation pipes. In the present invention, since the amount of nutrient solution supplied is not large,
The roots of the crops are not deeply immersed in the nutrient solution, increasing the amount of air supplied to the roots of the crops, and promoting the growth of the crops.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings.

As shown in FIGS. 1 and 2, a plurality of ventilation pipes 2 are arranged in parallel at suitable intervals on the upper surface of a cultivation shelf 1 constructed in a building, and between each ventilation pipe 2, ,
A panel 3 having a U-shaped cross section extending parallel to the longitudinal direction of the ventilation pipe 2 is fixed to form a groove 4, and each of the ventilation pipes 2
A receiving shelf 6 on which a mat 5 (to be described later) is placed and guided is protrudingly provided on the side wall of the upper end thereof, and a receiving shelf 7 is also provided in the center of the groove 4 parallel to its longitudinal direction. Shades 8 are attached to the top of each of the ventilation pipes 2 at predetermined intervals, and air outlets 9 are provided on the top surface at regular intervals along the longitudinal direction.
The air (warm and cold wind) blown upward from the cap is bent laterally by the shade 8 and is caused to flow out.

Between each of the ventilation pipes 2 and on the receiving shelves 6 and 7, holes 10 of a required size are formed at regular intervals in the longitudinal direction (matching the spacing between the air outlet ports 9 of the ventilation pipes 2) at positions closer to both sides. The mats 5 in each row are wound around drums 11 and 12 at both ends in the longitudinal direction, as shown in FIG. It is set as. In addition, at the upper center of the mats 5 in each row,
Nutrient solution supply pipes 13 are arranged parallel to the longitudinal direction of the mat 5, and each of the nutrient solution supply pipes 13 has a nutrient solution spout on both sides corresponding to the holes 10 provided at regular intervals in the mat 5. 14, and one end of each nutrient solution supply pipe 13 located on one cultivation shelf 1 is closed with a stopper 15, and each end is
For example, it is communicated with the header 16.

Various crops 17 are planted in the hole 10 of each pine 5 together with a medium 18 as shown in FIGS. 3 and 4, so that the roots of each crop 17 extend into the groove 4 below.

Although not shown, the nutrient solution accumulated in each groove 4 is sequentially collected by a pump or the like.

Now, as shown in FIGS. 3 and 4, when the crops 17 are planted together with the culture medium 18 in each hole 10 of each pine 5, the nutrient solution is sprayed from the nutrient solution supply pipe 13 above each pine 5. It is applied intermittently by dripping from the outlet 14 to the roots of the individual crops 17. Although the amount of the nutrient solution applied to the roots of each crop 17 is small, it descends along the roots of the crops 17 and accumulates in the groove 4. Groove 4
Collect the nutrient solution that has accumulated in the groove 4 as appropriate so that it does not accumulate deeply in the groove 4. It is also possible to perform cultivation by storing a large amount of nutrient solution in the groove 4, but in this case, the roots of the crops will be deeply immersed and the area exposed to the air will be reduced, which may hinder growth, so this is not preferred. do not have. Therefore, in the present invention, the nutrient solution is allowed to flow as needed.

Further, warm and cold air is supplied to the crops 17 through the ventilation pipe 2, and the temperature of the crops 17 is controlled.

Note that the air conditioning capacity can be reduced by partitioning the cultivation rack 1 into sections within the building with films and performing air conditioning intermittently.

[Effects of the Invention] As described above, according to the hydroponic cultivation apparatus of the present invention, a pine in which a crop is planted together with a medium is positioned between a plurality of ventilation pipes, and
A nutrient solution supply pipe is placed above the center of each pine, and the ventilation pipe and the nutrient solution supply pipe are arranged alternately on both sides of the crop, so warm and cold air is supplied to the crops from the ventilation pipe to maintain the temperature of the crop. By controlling the air flow to provide local air conditioning to the crops, and then supplying the nutrient solution dropwise to the crops, the roots of the crops are not deeply immersed in the nutrient solution, and the area of the roots exposed to the air is reduced. This increases the amount of air supplied to the roots of crops, and provides excellent effects such as reducing the amount of nutrient solution circulated through the dropwise supply of nutrient solution.
