Further, it is difficult to evenly embed the intervals between the pipes, and if the pipes are not evenly distributed, temperature unevenness occurs in the heated soil area j1, resulting in a difference in the growth rate of the plant. was there.

[0013] Furthermore, there is a disadvantage that a region outside the proper temperature range may be generated and the plant may be adversely affected.

Further, in an artificial soil environment such as rooftop greening, the amount of soil is small and the amount of water retention and heat storage is small, so that the temperature becomes excessively high in summer, which has the disadvantage of adversely affecting plants.

Therefore, the present invention solves the conventional problems, and provides a soil environment control device that can save labor for pipe installation work, can uniformly control the temperature in the soil area, and can cool the soil. The purpose is to provide.

Further, the above-mentioned conventional configuration is characterized in that the temperature sensor j
4, the temperature of the soil j2 is observed, and the flow rate or start / stop of the hot water is controlled by the controller j5 so that the detected temperature is within a preset setting range. In this case, since the optimum temperature range differs for each type, when the set temperature range of the controller j5 is changed by planting or the like, the setting of the temperature range cannot be changed without knowledge of the optimum temperature range. was there.

Accordingly, an object of the present invention is to solve the conventional problem, and an object of the present invention is to provide a soil environment control device that allows anyone to set an optimum temperature range simply by selecting a kind of a plant.

Further, the above-mentioned conventional configuration is characterized in that the temperature sensor j
4 to observe the temperature of the soil j2 and control the flow rate or start / stop of the hot water by the controller j5 so that the detected temperature is within a preset setting range. There was a drawback that the manager had to come to the site frequently to check the status because he could not be notified remotely.
