2. Description of the Related Art When cultivating a plant, the temperature of the soil of the plant rises when the temperature of the atmosphere rises in the summer. This rise in the temperature of the soil inevitably increases the root temperature of the plant, resulting in a decrease in the growth of some plants, and in some other plants, for example, the growth of plants and the activity of roots at the seedling stage. Slowing down. In order to prevent such a situation, it is said that it is preferable to keep the temperature of the soil in the range of about 10 to 20 ° C even if the atmospheric temperature rises. Further, when the temperature of the atmosphere becomes low in winter or the like, the temperature of the cultivated soil of the plant also decreases, and as a result, improvement of plant growth is hindered.

In order to deal with such a problem, conventionally,
Various measures are taken. The conventional technique will be described below with reference to FIG. FIG. 5A is an explanatory diagram of an example of a conventional plant cultivation method. In the figure, for example, in the house 1 where vinyl sheets or the like are used for the ceiling and the surrounding wall, the root 3
The plant 2 having the above is planted in the soil 4. In order to lower the temperature of the soil 4 when the temperature of the atmosphere is high in summer etc., the cool air 6 is sent from the indoor unit 5 of the cooling equipment into the house 1 to lower the temperature in the house 1, and thus the temperature of the soil 4. . After lowering the soil 4 and the like, the cold air 6 is discharged to the outside through a window or the like (not shown) of the house 1, or sucked into the indoor unit 5 and recirculated.

A second example when the temperature of the atmosphere is high is shown in FIG. 5 (B). In the figure, a plant 2 is housed in a house 1.
Soil 4 placed in a box-shaped container 7 for plant cultivation
Planted in. A large number of openings (not shown) are provided on the side surface and the bottom surface of the container 7. In order to lower the temperature of the soil 4 in summer or the like, the container 7 is placed on the rack 8 for supporting the container, and the cold air is blown upward from the pipe 9 provided in the rack 8. Since the side surface of the rack 8 is closed and a large number of openings are provided on the upper surface, the cold air 6 blown above the rack 8 through this opening is cultivated soil through the side and bottom openings of the container 7. 4 can be cooled. The cold wind 6 cools the soil 4 and then the house 1
It is released inside and released outside through a window or the like (not shown) of the house 1, or is sucked into a cooling facility (not shown) and recirculated.

As a third example of summer, etc., instead of generating cold air 6 in FIG.
There is a method in which a pipe (not shown) is embedded and cold water is circulated in the pipe to lower the temperature of the soil 4.

[0006] Further, conventionally, when the temperature of the soil 4 is lowered in winter, etc., the temperature of the soil 4 itself is raised from the viewpoint that the growth of plants can be improved by raising the temperature of the soil 4. I had no idea.

In order to solve the problems of the conventional example, the present applicant has previously filed Japanese Patent Application No. 2-182952. According to the invention of this application, it is possible to reduce the cooling cost because a small cooling device is sufficient, and the temperature of the soil is almost the same as the temperature around the plant by using the equipment used in the summer in the winter etc. It will be possible to improve the growth of plants.

However, in the invention according to Japanese Patent Application No. 2-182952, a plant is planted in a container or in the soil and the container is required, and the trunk groove and branch groove are constructed by blocks. Had to be done, and the equipment was expensive.

The present invention was devised in view of the above circumstances, and it is possible to lower the temperature of the soil with a cooling facility having a small cooling capacity in the summer when the temperature of the atmosphere is high and thus the facility cost and the operating cost are low. When the temperature of the cultivating soil is lower than the temperature around the plant in winter, etc., the method for cultivating the plant can bring the temperature of the cultivating soil to almost the same temperature as the temperature around the plant, and can be constructed at a low cost in terms of equipment. It is intended to provide a plant cultivation device.

It is jetted into the branch line portion 50 of the air recovery pipe via 1.

The cold air blown into the branch line portion 50 is introduced into the soil 72 through the air introduction opening 51 of the branch portion 50, and the temperature of the soil 72 is lowered. The remainder of the cool air blown into the branch line portion 50 is guided to the air intake port 12 via the branch line portion 50 and the main line portion 40. It should be noted that the cool air is introduced into the block 41 and the lid 42 before being guided to the air inlet 12.
Although the temperature rises slightly due to heat from the air supply device 1,
By the 0 air conditioner 14, it is again supplied to the main duct 20 of the air supply pipe as cold air.

In addition, the main duct 20 to the branch duct 30
The cold air that did not flow into the irrigation tank chamber 84 is supplied to the irrigation tank chamber 84 to cool the water in the irrigation tank 83. After that, it is guided to the air intake port 12 through the main line portion 40 of the air recovery pipe.

Since the water in the irrigation tank 83 naturally becomes cold water, it is not necessary to separately install equipment for cooling the irrigation tank 83.

Next, a case where the temperature of the atmosphere and the temperature of the soil 72 are low in winter etc. will be described. The air supply device 10 is operated with the air intake 13 of the air supply device 10 fully opened. The air warmed by the air conditioner 14 becomes warm air and is supplied by the blower 15 from the air outlet 11 to the main duct 20 of the air supply pipe. This warm air is supplied to each branch line duct 30 via the main line duct 20, and is ejected into the branch line portion 50 of the air recovery pipe via the air ejection port 31 of the branch line duct 30.

The warm air blown into the branch line portion 50 is introduced into the soil 72 through the air introduction opening 51 of the branch portion 50, and raises the temperature of the soil 72. The rest of the warm air blown into the branch line portion 50 is guided to the air intake port 12 via the branch line portion 50 and the main line portion 40. Note that this warm air flows through the air intake port 12

Furthermore, the temperature of the cultivated soil 72 may be 1
When the temperature is lower than the temperature around 00, the growth of the plant 100 can be improved by setting the temperature of the soil 72 to be almost the same as the temperature of the air around the plant 100.

Further, in the above-mentioned embodiments, the plant cultivating apparatus according to the present invention has been described as being provided in the house 1, but the present invention is not limited to this. Needless to say, it can be used even in the open-air without the house 1 even in a place where there is no wall and only a shade is provided. Also, even in the winter season, etc., it is not necessarily the case that the house 1 is present, but the plants 1
This plant cultivation device can be effectively used when the temperature is higher than the temperature soil 72 around 00.

Further, although the irrigation tank 83 is cooled, it is possible to cool the irrigation tank 83 by another appropriate means, and in some cases, it may not be cooled at all.
