Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a heating and growing structure for a crop for heating and growing the crop.

(Prior art) In conventional hot-bed cultivation, a covering sheet made of vinyl or the like is installed on an cultivated land, and the temperature inside the covering sheet is naturally raised by solar heat to grow and cultivate crops in the covering sheet. Was.

In addition, many devices for growing agricultural products using a pipe for adjusting the temperature are known, but all of them are complicated and large-scale devices.

(Problems to be solved by the invention) However, the method of naturally increasing the temperature in the cover sheet by solar heat as described above changes the temperature in the cover sheet daily depending on the strength of the solar heat, especially in rainy weather. However, there is a problem that the temperature rise in the cover sheet due to the above can hardly be expected.

This may adversely affect the crops and the crops may not grow normally.

In addition, complex and large-scale equipment often had a balance between cost and revenue.

An object of this invention is to solve the above-mentioned conventional problems.

That is, a heating panel for heating and growing crops is buried under the agricultural crop in the agricultural soil, and a heating medium is circulated through the heating pipe in the heating panel, so that the heating panel heats up daily. It is to provide a warming and growing structure for crops, which can heat and grow agricultural products at different temperatures, promote good growth of agricultural products, and have a simple structure and easy installation work. .

(Means for Solving the Problem) In order to solve the above-mentioned problems, the present invention penetrates through a panel main body made of a thick plate-shaped artificial pumice in approximately the center of the plate thickness from one end surface to the other end surface. A heating panel for heating and growing crops, which is configured by providing a plurality of rows of pipe insertion holes and inserting heating pipes through which the heated heat medium is circulated, is used to produce agricultural products in agricultural soil. It is characterized by being buried underneath.

(Function) When the heating panel is buried in the agricultural soil and the agricultural product is grown, the moisture contained in the agricultural soil permeates into the pores of the panel body using artificial pumice. become. In such a state, when the heated heat medium is circulated through the plurality of heating pipes inserted in the panel body, the moisture permeated in the bubble holes of the panel body is heated.

The panel body itself made of artificial pumice stone is porous and has excellent heat insulation due to the formation of bubble holes inside, but the water that has penetrated into the bubble holes is
It has the property of being easily heated to a high temperature, and since it is a minute amount, it can be heated easily and surely by the heat medium circulated in the heating pipe.

When the moisture soaked in the panel body is heated, the moisture soaked in the agricultural soil is also heated by the radiant heat, heat conduction and the like. As a result, the crops planted in the agricultural soil are uniformly heated to a temperature suitable for growing by the radiant heat and heat conduction of water in the agricultural soil, and the growth of the agricultural crops is promoted.

(Example) Hereinafter, the Example of the heating cultivation structure for crops which concerns on this invention is described based on drawing.

FIG. 1 is a vertical sectional view showing an example of a heating and growing structure for agricultural products according to the present invention, FIG. 2 is a schematic perspective view of a heating panel used for the heating and growing structure, and FIG. FIG. 6 is a circuit diagram for explaining a circulation path of a heat medium in the display panel.

In the heating and growing structure for crops of the present invention shown in FIG. 1, the heating panel 1 is embedded in the agricultural soil T, and the agricultural crop N is provided on the surface side of the agricultural soil T above the heating panel 1. Planted.

The heating panel 1 is provided with a plurality of rows of pipe insertion holes 23 penetrating from one end face 21 to the other end face 22 of the panel main body 2 made of a thick plate-shaped artificial pumice in the approximate center of the plate thickness. The heating pipe 3 is inserted through the pipe insertion hole 23. The heated heat medium is circulated in the heating pipe 3. The heating pipe 3 is connected to a heating device 4 described later.

The panel body 2 of the heating panel 1 is made of a thick plate-shaped artificial pumice stone (for example, the Hebel brand name manufactured by Asahi Kasei Corporation), and is porous with a large number of bubbles provided inside.

The heating pipe 3 inserted into the pulp insertion hole 23 has a diameter of 10
mm to 20 mm.

The circulation path of the heat medium circulated in the heating pipe 3 is as shown in FIG.

That is, the heating pipe 3 is provided with a heating device 4 described next.
It is connected to the.

The heating device 4 is installed on the side of the farmland (not shown), and includes a boiler 5, a circulation pump 6, a supply side header 7 and a recovery side header 8, and a circulation pipe 9 that connects the four in series. It consists of and.

The supply-side header 7 and the recovery-side header 8 are connected to one end and the other end of the heating pipe 3, respectively.

Next, the operation of the heated growing structure for agricultural products according to the present invention will be described.

When the heating panel 1 is embedded in the agricultural soil T and the agricultural crop N is planted, the moisture in the agricultural soil T is infiltrated into the pores of the panel body 2 made of artificial pumice in the heating panel 1. become. In this state, when the heating medium is circulated and supplied to the heating pipe 3 of the panel body 2,
The moisture permeated into the panel body 2 is heated by the conduction heat from the heating pipe 3. The moisture is heated to a high temperature easily, and since the amount of the moisture soaked in the panel body 2 is small, the moisture is reliably heated by the heat medium circulating in the heating pipe 3.

The agricultural soil T in which the heating panel 1 is embedded is also porous and has heat insulating properties, but since the moisture has also penetrated into the agricultural soil T, it penetrates into the heating panel 1. The moisture in the agricultural soil T is also heated by the radiant heat and heat conduction of the moisture. As a result, the agricultural crop N planted in the agricultural soil T is uniformly heated to a temperature suitable for growing due to radiant heat of moisture in the agricultural soil T, heat conduction, and the like.

When a large amount of energy is given too much, the agricultural product causes an abnormality such as stopping cell activity, but it grows well by giving a small amount of energy uniformly over a long period of time. The heating of the crop N by the heating panel 1 thus uniformly gives a small amount of energy over a long period of time, and the growth of the crop N is promoted.

In this heating and cultivation structure for agricultural products, a heating panel 1 configured by inserting heating pipes 3 into a plurality of rows of pipe insertion holes 23 provided in a panel body 2 made of artificial pumice is provided in an agricultural soil T. Since it is only necessary to bury it in, the construction work is simple, the equipment is minimal, the construction time is short, and the overall weight is light.

(Effects of the Invention) As described above, according to the present invention, a heating panel for heating and growing crops is embedded in agricultural soil, and a crop is planted in the agricultural soil in which the heating panel is embedded. As a result, it is possible to heat and grow agricultural products at a uniform temperature every day due to the heat generation effect of the heating panel, and it is possible to promote favorable growth of agricultural products. Moreover, the structure is simple and installation work can be done easily. In addition, it has the effect of being inexpensive. In addition, since the panel body is made of artificial pumice stone having numerous bubble holes, it is lightweight and easy to handle during construction. Moreover, it is possible to uniformly heat the agricultural products with a small amount of energy.
