It is fixed at intervals of about 60 cm at the top of the power supply is connected to the power supply (3). The temperature change of the warming treatment is measured by using an infrared thermometer, which is a temperature measuring device (4), and measures the temperature of the warming treatment, based on the measured temperature, so that the temperature difference between the control and the warming treatment can be maintained in a certain range. The control device 5 regulates the power supply of the power supply device 3 to the heating module 30. In addition, the soil temperature-moisture sensor 6 and the soil respiration sensor 7 as soil observation sensors measure the environmental change of the soil due to warming, and record the measured data in the data logger 8 to measure the control data of the control. Compare with

The heating module 30 is fixed by the support, and increases the temperature in order to create a warming environment for trees, soil, and the like outdoors. In this case, the heating module is preferably an infrared lamp, it is preferable to install so as to be located at the center of the upper end of the warming treatment target object to create a warming environment. When using an infrared lamp as the heating module 30, there is less disturbance of the ecosystem compared to the warming of trees or soil using a heating wire, the warming using a field chamber and the passive night warming method, and can create an environment similar to the actual climate change. have.

In addition, when creating a warming environment for the tree, it can be installed on the top at an interval of 50cm to 1m relative to the tree, preferably installed at intervals of 60cm with the tree is advantageous to generate a uniform warming effect.

At this time, the support for supporting the heating module may further include a height adjustment device for adjusting the height. Through this, the position of the heating module can be adjusted according to the height of the trees growing in the warming treatment zone, so that the outdoor experimental warming and precipitation control system can be effectively applied.

The heating module 30 is connected to a power supply device to receive power, and the power supply device may further include an auxiliary power supply device, and the auxiliary power supply device is preferably solar power generation. The solar power generation includes a heat collecting unit for collecting solar heat and a heat storage unit for converting it into electrical energy to be used as a power source, and when the power supply of the power supply is cut off, the power supply can be preliminarily supplied, so that the monitoring module Allows you to record data continuously.

The control module includes a temperature measuring device (4) for measuring the temperature change by the heating module and a temperature control device (5) for controlling the temperature of the warming process by controlling the power supply of the power supply to the heating module; In other words, it controls the temperature change of the warming treatment unit in the outdoor similar to the actual warming phenomenon.

Specifically, the temperature measuring device 4 is heated by the heating module is a warming treatment target to observe the change in a warming environment, such as plants, soil, and thereby measures the change in temperature on the warming treatment. The temperature measuring device may be an infrared thermometer, but is not limited thereto.

In addition, the temperature control device 5 when the warming treatment zone is heated by the heating module 30 reaches a temperature increased by a predetermined width to create a warming environment based on the control temperature, the heated warming treatment sphere It controls the heating module so that the temperature can be kept constant.

The monitoring module serves to continuously monitor the change of environmental factors due to the temperature rise by the heating module 30, and includes a data logger 8 and soil observation sensors 6 and 7.

The data logger 8 stores and controls the temperature data measured by all the recording and temperature measuring devices measured by the soil observation sensor, namely the soil temperature-moisture sensor 6 and the soil respiration sensor 7. do. As a specific example, a data logger (CR3000, Campbell Scientific Inc., USA) may be used, but is not limited thereto.

The data logger is preferably located in the data logger case, and the data logger case serves to protect the connection portion between the data logger and the soil measurement sensor, and is preferably made of a material having excellent thermal insulation and durability. Positioning the data logger at the bottom or bottom of the data logger case can improve fluidity with the soil measurement sensor.

Soil temperature is an important factor for mass circulation and plant growth in the soil. It is also important to observe and predict how the soil's temperature rises as the temperature rises. The soil measuring sensor serves to observe the change in the soil in the experimental warming and precipitation control system, and preferably includes at least one selected from the group consisting of a soil temperature sensor, a soil moisture sensor and a soil breathing sensor.

Soil temperature varies greatly depending on soil depth, so when the soil temperature sensor is installed, the soil depth standard should be set and installed at a constant depth. The soil temperature sensor is preferably installed at a position where plant roots are mainly distributed in the soil to measure the temperature of the soil depth having a large influence on the plant, and more preferably to position the soil temperature sensor at a depth of 5 cm to 15 cm from the surface of the soil. Do. The soil temperature sensor is preferably capable of measuring a temperature in the range of -35 to 50 ℃. As a specific example, a soil temperature moisture sensor (CS655 by Campbell scientific) that can measure soil temperature and soil moisture together at a point in the soil may be used, but is not limited thereto.

When the soil temperature sensor is installed, it is preferable to first measure the exact depth of the portion to be installed and form a hole for burying the soil temperature sensor in the soil, and then bury the soil temperature sensor horizontally with the ground and cover the soil. In addition, it is advisable to install a warming system outdoors and preliminary experiments to ensure that the measured values are stable and to collect data.

In addition, the soil temperature sensor is preferably installed in a position where the disturbance of the soil as small as possible, in particular, it is good to reduce the effect on the root as much as possible. In addition, it is preferable to install at a spatially constant position in the warming treatment and control, respectively, so that the conditions of soil temperature measurement are similar. In addition, since disturbance to the root of the vegetation may occur, it is preferable to install at the same depth and position in order to give as little disturbance as possible.

Soil moisture, which is an environmental factor in ecosystems, is very important, and moisture in soil, which is dependent on climate change, has a very important effect on vegetation effects. Soil moisture, for example, is important because it affects the process of soil formation and nutrient effectiveness, and the roots change their ability to absorb water and nutrients. To this end, the soil moisture sensor serves to measure the moisture content of the soil.

The soil moisture sensor should be careful when installing because the variation is large depending on the depth of the soil. In the case of the soil moisture sensor, unlike the soil temperature sensor, since it can be installed diagonally, disturbance of the roots of the vegetation may occur. Therefore, it is preferable to install the soil moisture sensor at the same depth and position to minimize disturbance of the irradiation paper.

According to an embodiment, a device capable of measuring soil moisture and soil temperature together may be used. The device is installed horizontally on the floor.

Rising temperatures significantly change the environment in the soil and, in particular, increase soil respiration associated with soil organic matter degradation and root growth. Therefore, monitoring of how soil respiration changes with temperature and rise in soil temperature is necessary. The soil respiration sensor serves to observe changes in the respiration of the soil, and when the soil respiration sensor is installed in the soil, the soil is dug to a certain depth, and the soil is filled in a vertical direction after installation. At this time, it is preferable that the soil pressure is not generated.

In order to continuously record the data measured by the soil observation sensor, the data logger may record data measured at intervals of 1 minute to 60 minutes, and more preferably, to record data measured at intervals of 30 minutes. good.

3 shows a drop hose according to an embodiment of the present invention. Referring to FIG. 3, the precipitation increase port 130 includes a drop hose (54 in FIG. 1, 60 in FIG. 3). Dropping hose 60 is connected to the conduit 52, the bottom is formed with holes for dropping the rainwater supplied from the conduit 52 to the soil portion (20).

Dropping hose 60 includes at least one drop button 70. The drop button 70 is installed in each hole of the drop hose 60 and discharges rainwater in the drop hose 60 to the outside through the drop button 70 when the pressure exceeds a predetermined level.

For example, the drop hose 60 may be 1.6 ~ 2.3L water per hour. However, the drip button 70 is capable of adjusting the flow rate of water to 0 ~ 40L per hour. The drop button 70 is designed to be watered in a plurality of holes, and by turning the cap from which the water comes out to the left and right, it is possible to adjust the amount of water to be watered. Therefore, since water is watered through a plurality of holes per one drop button 70, more water can be flooded in a larger area than the drop hose 60.

Therefore, it is possible to effectively irrigation at a faster speed than the drip hose 60 and to evenly water all areas of the soil portion of the precipitation increase port 130.

Referring again to FIG. 1, according to an embodiment, two precipitation increasing holes 130 are connected to one pump 51 through a conduit 52. This may reduce the length of the conduit 52 connected to the precipitation increase port 130. Therefore, there is an effect that can reduce the precipitation lost in the conduit 52 or stays for a long time.

In the present specification, although the number of precipitation increasing holes 130 connected to one pump 51 through the conduit 52 is described as two, if the length of the conduit 52 can be reduced within the range of the present invention The technical idea is not limited to the number of precipitation increasing holes 130 connected to one pump 51.
