Description

  The present invention is one of the systems that grow plants by directly irradiating the root hair of the plant with geothermal heat, but provides a system with high energy efficiency and energy-saving structure.

  In recent agricultural technology, geothermal application has become a common sense for plant cultivation. In general, there are many methods in which pipes are buried in the ground, heated with a boiler and circulated through the pipes. The problem with this method is that it is difficult and expensive to manage the boiler fuel economy and nighttime.

  Agricultural air conditioning equipment depends on the price of the crop. It is not profitable unless it is a very expensive crop. There are many nursery houses among large farmers who have made greenhouses and air-conditioning for cultivation of watermelon, melon, strawberries, etc. from the climate of Japan. Especially in the past few years, air conditioning in the strawberry cultivation house has become prominent. However, there are no geothermal heat-retaining facilities yet.

Means for solving the idea

In the case of a boiler for air conditioning in a house, the management cost and running cost are high. Therefore, other effective systems are considered.
The present invention considered management, control and efficiency. Theoretically, the most effective method is to satisfy the geothermal heat and adapt the residual heat from the geothermal heat to the air conditioning in the house. Proposal 1 is that the cultivation floor of strawberries has many horseshoe shapes, and is usually hygienicly protected so that black vinyl is covered on the horseshoe shape floor.

Strawberry seedlings are planted in the center of the top of the horseshoe-shaped floor, and the root hairs extend along the horseshoe shape. In this case, the most effective geothermal device is preferably a pipe heater embedded in the bottom of the horseshoe floor.
In the present invention, a bulk heat system is adopted as an energy saving structure. Furthermore, a carbon heater that radiates far-infrared electromagnetic heat is adopted, and a belt-like heater is inserted in a long length into a connected fume pipe having a diameter of 10 cm.

The construction is simple, and each time the pipes are connected during embedment, the end of the belt heater is tied and pulled with a string and fixed to a long length. To supply electricity, a long wire is connected so that a large capacity electric wire follows the belt heater. For temperature control, the point sensor of the thermal controller is fixed between the top of the vip and the soil, and the temperature is controlled by the controller in consideration of the root hair ambient temperature of 15 ° C to 20 ° C. This method is effective when using the “cloud temperature”.
In particular, in the case of strawberries, from January to March, depending on the heat retention of the root hair, the flowers do not bloom and affect the harvest.

In the case of planting crops with a wide planting width in two rows, geothermal heat is embedded with a heat insulating material and a wide carbon surface heating element at a depth of 40 cm to 50 cm in the ground. Electricity is supplied and controlled by connecting a controller every 7m. The temperature sensor is a point sensor embedded in the vicinity of root hair having a depth of 15 cm to 20 cm in the ground.
The carbon surface heating element emits an optimum far-infrared electromagnetic wave of about 10 microns and has a high power conversion efficiency and an energy saving structure, which is optimal for geothermal use.

Effect of device

Usually, strawberry root hairs are said to stop growing if the temperature in the soil falls below 5 ° C. If root hair growth stops, flowering disappears. In order to solve such a situation, it is optimal to keep the temperature at 15 ° C. to 20 ° C. in winter with the energy saving pipe heater of the present invention.
If the heating value of the belt-like heater is set to 30 dags, the heat will be dissipated in 30 minutes in order to bring the root hair ambient temperature to 15 ° C.

Even in the case of two rows of nurseries, if the distance between the seedlings is 50 cm, the width of the embedded heater is 50 cm and the root hair temperature of the two seedlings can be satisfied. The far-infrared electromagnetic wave heat from the carbon surface heating element is penetrable, has high heat conversion efficiency, and has an energy saving structure. Low fuel consumption and high practicality.
Pepino imported from New Zealand by this method was cultivated once a year locally in Japan, but in Japan it has a track record of being cultivated every month because of the construction of the present invention.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a cross-sectional view of a horseshoe-shaped floor Va that is usually adapted to strawberry cultivation. A fume pipe He having a diameter of 10 cm is embedded in the center of the horseshoe-shaped floor Va. Inside the fume tube He, a strip carbon heater Ch having a width of 7 cm and an electric wire De supplementing the electric capacity are inserted integrally with the strip carbon heater Ch. Electricity is supplied at every 10m position of the belt-shaped carbon heater Ch by installing a switchboard and connecting with a ± line from the electricity De. The important thing here is that the installation of the joint that connects the fume tube He does not require water at a later date. Install completely. The carbon heater Ch is attached by inserting a long string at the tip position and pulling the string through the next fume tube He for each joint and pulling the band-shaped carbon heater Ch. The temperature control sensor Se is attached to the upper surface of the fume tube He.
Finally, the black vinyl sheet Be is covered on the surface of the horseshoe-shaped floor Va and completed.
If the temperature of the sensor Se is controlled at 20 ° C. to 25 ° C., the temperature around the root hair Cm is 15 ° C. to 20 ° C., and the growth temperature is maintained.
Next, an embodiment of the present invention will be described with reference to FIG. It is a floor to plant strawberry seedlings in two rows. The heat insulation system in this case employs a heat insulating material Da and a carbon surface heating element Ch having a width of about 50 cm at a depth of 40 cm to 50 cm from the floor upper surface. In this case, the bulk heat is applied to the inner root hair Cm indicated by the dotted line A in the oblique line.
For electrical connection, a controller Cn and a power cord are wired at positions 7 m to 10 m, and ± code De is connected from this position to the carbon surface heating element.
The temperature sensor Se is inserted and fixed around the root hair Cm and is controlled at a constant temperature.

  The construction method of FIG. 1 or FIG. 2 of the present invention is considered to be a system that can be applied to the cultivation of watermelons in Kumamoto in the case of FIG. The construction method shown in FIG. 2 can be applied to the case where it is made once again by cultivation of melon and watermelon in a pive house around Chiba and Ibaraki. However, the plant can be cultivated if the far-infrared irradiator of our application is applied to the problem of irradiation with sunlight when re-creating in winter.
