FIG. 1 is a view showing a drought simulation facility of a plant according to an embodiment of the present invention. The soil storage unit 10 has an upper surface opened and a soil 13 stored therein. A water supply pipe for supplying water to the soil 13 stored in the soil storage unit 10 and a water supply pipe for supplying water to the soil and the soil A pump 60 for supplying water to the water supply pipe through the temperature and humidity sensed by the sensing sensor unit 40 and a pump 60 for opening and closing the non- And a control unit (1) for controlling the operation of the motor (50).

The soil storage unit 10 is formed of a concrete material that prevents water from flowing from the outside and prevents water from flowing into the soil storage unit 10. The soil storage unit 10 is formed of a stone or soil, May be covered with a material such as plastic or vinyl to block the water.

A plurality of drainage valves 14 are formed on the upper and lower sides of the longitudinal wall surface of the soil storage unit 10 so that water can be discharged from the soil storage unit 10. The support bars 31 of the non- A plurality of insertion ports 15 that can be engaged are formed.

A drainage path (20) formed at a predetermined interval is formed outside the soil storage part (10) so that the water discharged from the soil storage part (10) can be drained.

Is installed in an insertion port (15) formed at the upper end of the soil storage part (10), and a non - screening film (30) is installed to block rain or snow flowing from the outside.

The non-slip film 30 is inserted into the insertion port 15 and is coupled to a supporter 31 which is formed in a streamline shape to cross the upper side of the soil storage part 10. The non-slip film 30 covers the outside of the supporter 31, (32) for preventing the snow from flowing into the soil storage part (10).

The blocking film 32 may be opened or closed by rotation of the motor 50. The rotating bar may be connected to the blocking film 32 to be opened and closed through the motor 50, The soil storage unit 10 can be opened or closed.

When the soil 13 is stored in the soil storage section 10, the gravel 11 is stacked at a predetermined height from the floor, the soil 13 flows into the gravel 11 side on the upper side of the gravel 11, And the soil 13 is stacked on the top of the soil outflow preventing net 12.

On the upper side of the stacked soil 13, a plurality of water supply pipes are provided to supply the water supplied through the external pump 60 to the soil 13.

A sensing sensor unit 40 including a first sensor unit 41 and a second sensor unit 42 is installed in the non-shielding film 30 and the soil 13 to sense temperature and humidity.

The sensor unit 40 is formed of a first sensor unit 41 and a second sensor unit 42. The first sensor unit 41 is installed on the support 31 of the non- A first temperature sensor 41a for measuring the temperature of the air and a first humidity sensor 41b for detecting the presence or absence of rain by measuring the humidity of the atmosphere.

When the first sensor unit 41 senses the atmospheric temperature inside the non-shielding film and the moisture in the air and transmits the sensed moisture to the control unit 1, the set value set in the control unit 1 and the humidity detected in the first humidity sensor 41b When the humidity value is higher than the set value, the motor 50 is operated to unfold the shielding film 32 so that external rain or snow can not flow into the soil storage unit 10.

The water supply pipe is connected to an external pump 60 so that a large number of water supply pipes are installed above the soil 13 to supply the water supplied through the pump 60 to the soil 13.

The water supply pipe may have a plurality of holes formed on the outer side thereof so that water can be supplied to the soil 13, thereby discharging the water.

The pump 60 pumps external water and supplies the water to the water supply pipe.

At this time, the pump 60 is connected to the control unit 1 to detect the temperature and humidity of the soil 13 detected by the second temperature sensor 42a and the second humidity sensor 42b of the second sensor unit 42, If the humidity and the temperature of the soil 13 do not reach the set value of the soil 13, the pump 60 is operated to supply the water.

In such a configuration, the control unit 1 automatically operates the motor 50 and the pump 60 through the control signal, so that the environment inside the soil storage unit 10 can be drought or an appropriate irrigation water.

The soil storage tank 10 is composed of a plurality of soils and controls the pump 60 and the motor 50 in the control unit 1 in accordance with each environment so that each soil storage unit 10 is exposed to drought, So that the environment can be formed singly or in combination.

The drain valve 14 can be operated manually or automatically, and can be operated through a control signal in the control unit 1 when it is automatically operated. When the soil 13 is automatically operated through the control unit 1, if the soil 13 has a water content higher than a set value according to the moisture content of the soil 13 detected by the second sensor unit 42, Thereby discharging moisture.

The supporting frame 31 of the non-shielding film 30 is provided with a thermal imaging camera 70 and can transmit a thermal image photographed by the control unit 1 so that the temperature of the soil 13 can be confirmed.

The above-described configuration will be described with reference to an embodiment.

The drought simulating plant of the present invention is composed of a soil storage tank 10 capable of filling soil with plants and a non-slushing layer 30 capable of blocking rainfall inflow, and is designed to have a total size of 23.2 m 23.5 m. Three soil storage tanks 10 (20 cm thick) 6.0 m 21.1 m in size were placed in the drought simulation facility of the plant.

In each soil storage tank 10, a total of 16 drainage valves 14 were installed in a soil storage tank 10, four in each case 15 cm above the bottom of the side and 15 cm below the top of the side. The drain valve 14 was closed when water was supplied, and was opened when drying. In each soil storage tank (10), gravel (11) was laid up to 15 cm above the floor to smooth drainage. On the gravel (11), a nonwoven fabric, which is a soil spill prevention net (12), was laid and the soil (13) was filled to a depth of 80 cm. The water exiting the soil storage tank 10 when the drain valve 14 is opened is immediately designed to be sent through the drain pipe 21 embedded in the drainage path 20 buried outside the drought simulation facility or underground of the plant Respectively.

On the other hand, a rainfall facility was constructed on the soil storage tank (10) to prevent the inflow of rainfall. When the rain is not present, the ceiling of the rainfall facility and the blocking film 32 serving as an opening are opened to allow the sunlight to enter the maximum, so that the humidity inside and outside can be maintained. The motor 50 is automatically operated through the control signal of the control unit 1 in accordance with the detection so as to prevent the inflow of rainfall by closing the skirt of the non-skimming film 30 and the shielding film 32 as the side skirt.

In the drought simulation facility of the plant, water was supplied to the plants using a water supply pipe. The dewatering treatment section is divided into a drought treatment section and an appropriate irrigation section, and a drip hose is connected to the soil storage tank. The water supply time and the water content of the soil 13 are sensed through the second humidity sensor 42b, To create a drought condition.

The moisture content of the soil (13) was measured using a humidity sensor. The water content of soil (13) was measured at intervals of 30 minutes from July 30, 2012 to November 2, 2012, and the average value was calculated by day and converted into a daily change graph. The moisture content of the soil in the irrigation canal soil (13) was maintained at 10.74 ~ 18.13%, while the moisture content of soil (13) in the drought treated soil was 6.83 ~ 11.68% And it was found that dry stress environment was formed in the drought treatment area.

Table 1 below shows the results of comparing the phenotypic traits in the drought-treated soil with the appropriate irrigation water formed on the soil storage unit 10 constructed as described above.
