Abstract

PURPOSE:To provide the subject practical engineering method of low cost capable of conducting planned production all the year round, ensuring crops to be raised even in winter by equipping part of a pipe house generally available with U-shaped beds and carbonaceous planar exothermic bodies. CONSTITUTION:Thermal insulating U-shaped structural beds are laid in appropriate rows in a greenhouse of wide area being in use. A planar exothermic body capable of bringing soil temperature to 20-25 deg.C is then spread all over the bottom of each of the beds, mixed soil such as organic fertilizer is loaded thereon, and above it, a PVC film is stretched in a small tunneled manner, and the space inside it is also provided with additional planar exothermic bodies just under the ceiling and on the U-shaped bed to make an air conditioning in the small tunnel at an appropriate temperature along with replenishing it with part of sunlight in the form of far-infrared radiation. In addition, anions are generated to promote plant growth, leading to full-matured fruits; therefore, the subject engineering method is the most effective from the viewpoint of these advantages.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to heat insulation and promotion of growth for adapting an existing pipe house to a winter greenhouse house.

[0002]

2. Description of the Related Art As a conventional method for adapting a pipe house to a greenhouse, there are a hot air system, a hot water system, use of groundwater, etc., but they are not economically economical and the running cost of a hotbed line is particularly high. In addition, it keeps the geothermal heat completely flat,
Moreover, I have never seen a system that can control the growth temperature in a small tunnel during the cold period, and I have not seen any practical examples.

DISCLOSURE OF THE INVENTION The present invention is a method of uniformly radiating geothermal heat in a wide range, adopting a method of bringing temperature to the whole rooting, and the preheating of the preheat affects the earth's surface in small tunnels. In addition to protecting it, the under temperature in the tunnel is provided by further laying a heat generating sheet or hanging a small heat generating sheet above the small tunnel, and it is an electric field that emits (-) ions during the day and keeps it warm at night By using it as a sheet, the temperature in the small tunnel can be satisfied and the growth of plants can be promoted. It can be said that the most ideal cultivation method is that the temperature can be controlled with sensors for both geothermal and air conditioning in small tunnels.

[Means for solving the problems] The purpose adopted by farmers is
Equipment costs and maintenance costs are low, and cultivation efficiency is high. When the carbon-based surface heating element of the present invention is buried in the ground, the muffled heat in the ground effectively acts on a wide surface and the rooting temperature of 20 to 25 ° C. can be obtained even with a low resistance. One rice range can be brought about by a heating element with a width of about 30 cm.
With the total amount of electricity usage money (4,5 months) buried in two rows of 0M pipe house, it could be cultivated for about 50,000 to 60,000 yen. Further, since the present invention provides a temperature in a small tunnel, a heating sheet is installed on the upper surface of the loaded soil to correspond to the nighttime temperature, and by placing fruits on the sheet, far infrared rays of the carbon-based heating element are absorbed, and a shortage occurs. You can replenish the sunshine hours. The present invention is a construction method in which even if the outside temperature is -10 ° C, a small tunnel is double-laid in the pipe house, the air conditioning of the small tunnel is emphasized, and the temperature and (-) ions are filled in the range where the plant grows. It is the simplest and most innovative method that is effective, inexpensive, and can be planned for cultivation.

The nursery bed of claim 2 is also a construction method based on the theory that by covering sand with a wide range of heat of clouding, it can be completely controlled to an appropriate temperature, and is more uniform and durable than the conventional nichrome hotbed line method. It is the most effective method because it can be cultivated with 100% probability and the running cost is 1/3.

[0006]

[Operation] The method of burying the surface heating element in the soil has a high effect of raising the mist, and since the rooting surface is evenly distributed over a wide range due to the burial depth, it is 1/2 to 1 / of the rooting surface. A surface heating element having a width of 3 and a resistor of 15 to 20 dag serves the purpose. Furthermore, by installing a surface heating element on top of the loaded soil, it is possible to radiate far infrared rays to the air conditioning and fruits in the small tunnel and to supply part of the sunlight, which is essential for winter cultivation. It produces the most rational action that satisfies the conditions.

EXAMPLE FIG. 1 shows an example of a growing cultivation method. Inside the pipe house 1, a carbon surface heating element 3 having a width of 1/2 to 1/3 of the concave width is installed above the U-shaped heat insulating material 2 such as Styrofoam, and a resin mesh mesh is provided above the carbon surface heating element 3. Four
And the soil 5 mixed with organic fertilizer and the like is loaded on the upper part thereof, then a vinyl sheet (mulch) 6 is stretched, and the surface heating element 7 is installed long. Then, after the vinyl 9 is stretched over the small tunnel pipe 8, a small width of surface heating elements and (-) ion generating electric field 10 are stretched under the small tunnel pipe. The surface heating elements 7 and 10 are adjusted according to the climate of each region.
As described above, according to the present invention, the small tunnel 8,
9 is a system for effectively cultivating crops inside, and can be provided as the most effective construction method of an energy-saving structure that effectively uses the muffled heat of the surface heating element. FIG. 2 shows that a pipe house 1 has a concave heat insulating material 2 such as Styrofoam, a surface heating element 3 is provided therein, and a surface heating element is protected by a vinyl 4 for preventing corrosion. After loading sand 5 etc., cover the upper part with vinyl sheet 6, then 8, 9
Form a small tunnel house. This construction method is more effective than the construction method in which meandering wiring of nichrome wire is applied to the seedling raising pot evenly with the muddy temperature of the soil (sand) 5 as in the case of FIG. 1, and a uniform seedling is provided with energy saving with a probability of 100%. It can be provided as the most innovative cultivation method.

Succeeded in cultivating lunar watermelon. This is the first achievement in this area, and the fact that the pipe house could be cultivated by the above-mentioned construction method is
This is the first time in Japanese agriculture. Easy to install,
The electric control was perfect, and the total amount of electricity used for greenhouse cultivation per anti-step was 150,000 yen in 4 months, and the cost per melon was 53 yen, which was the lowest. The accuracy is also very high at 16 ° for melon and 14 ° for watermelon, and the amount of water is adjusted based on the fixed-term fertilizer and U-shaped structure cultivation, and the far-infrared effect emitted from the heating element was the most effective for winter cultivation. Was also proved. Based on claim 2, as a result of adapting melons and watermelons to 20 farms in the Asahi-mura area of Ibaraki prefecture, uniform and strong seedlings succeeded with a probability of 100%.
