Description

[Detailed explanation of the invention] When cultivating crops such as vegetables under forced cultivation or suppressed cultivation in greenhouses, plastic tunnels, etc., fill a bag made of vinyl or polyethylene film with water, and use the bag containing this water to grow the crops. When the air cools down at night, it prevents the soil temperature and the air temperature in greenhouses and tunnels from rapidly cooling down, and helps crops grow. It is known to promote smooth growth.

However, fields are rarely completely horizontal,
Because there is always some slope, if you store water in a long cylindrical bag and place it on top of a field, the water inside the bag will collect in the low-lying areas, causing damage to the field. Overall, it has not been possible to prevent sudden changes in soil temperature, etc. on average, and therefore it has not been possible to increase effectiveness.

In addition, in order to prevent water from shifting when the long bag is placed on the ground in a field, the length of the bag is shortened to form a cushion-like bag, and the water is placed in the long bag. It has been proposed to fill the bags with water and place them side by side on the ground inside a plastic greenhouse or plastic tunnel, but in this case, a large number of bags would have to be filled with water and drained. Each bag must be sealed individually, so you can carry water,
The operation of sealing and opening the bags is troublesome and requires a lot of effort, and each bag must be equipped with a stopper that seals the bag to prevent water from leaking, which results in an overall high cost. had.

The present invention has been made in view of the above, and an embodiment of the present invention will be described below with reference to the drawings.As shown in Figs. A long main body 1 that can accommodate water inside and does not leak water is provided with a partition portion 2 that prevents the flow of water contained in the main body 1 in a direction substantially perpendicular to the longitudinal direction, which is fused between the front and back surfaces of the main body 1. The partition part 2 is provided with a communication part 3 that is brought to one side and communicates with the cylindrical interior of the adjacent main body 1, and an end part 4 of the partition part 2 that is close to the communication part 3 is provided. The above-ground heat insulating material for agricultural use is constructed by fusion-bonding the front and back surfaces of the main body 10 with a larger area than the partition part 2, and providing a through hole 5 in the end part 4 of the partition part 2. implement.

In the figure, 8 is the frame of a vinyl house or vinyl tunnel, 9 is a plastic film coated on the frame 8, and 1
0 indicates crops and 11 indicates the ground.

The ground heat insulating material of the present invention is as described above, and in order to use it, one end of the long main body 1 is closed, or one end is lifted and fixed at a high position, and the other end is inserted into the main body 1. When water is injected, the water fills into the main body 1.

In this case, since the main body 1 is partitioned by a large number of partitions 2 in a direction substantially perpendicular to the longitudinal direction, the main body 1 does not bulge out in the partitions 2, but in the middle between the partitions 2. It bulges out and becomes somewhat flat, resembling a continuous cushion, and covers the ground 11 over a relatively wide area.

Then, the string 6 is inserted through the communication portion 3 into the through hole 5 as described above.
When the body 1 is tied and closed, the flow of water to the inside of the main body 1 is stopped, and the water contained between the partitions 2 of the main body 1 does not flow into the adjacent space. When installed on the ground, it can sufficiently store heat and improve the growth of crops.

Since the insulating material of the present invention has a long cylindrical shape, if you want to leave the communication part 3 open and inject water into it, close one end or place it in a high place and press the button. You can distribute water extremely easily by just injecting water from the end, and you can also drain the water after use and store it.
All you have to do is leave the end open and leave the end in a low place, which has the advantage of not requiring much effort to use the heat insulating material of the present invention, and also allows water to be removed. The extracted main body 1 can be rolled up or folded to have an extremely small volume, making it convenient for storage and transportation.

In particular, in the present invention, the end portion 4 near the communication portion 3 has a large area, so that the partition portion 2 is reinforced by this end portion 4 and is difficult to break. By selecting an arbitrary string such as a rubber string, plastic string, or cotton string, and tying the communication section 3 with this arbitrary string, the communication section 3 can be closed very easily and firmly. This makes it possible to prevent the water in the main body 1 from moving into the adjacent main body 1 through the communication part 3 when the main body 1 containing water is placed on this slope. When draining water from the inside of the connecting portion 1, if the string that binds the communicating portion 3 is tied in a flower knot, it will be very easy to release the tied state.

Furthermore, according to the present invention, since there is a through hole 5 at the end 4 of the partition part 2, if a rod or the like is inserted into the through hole 5 and the rod is stuck into the ground, water can be removed even on a slope. The effect of preventing the movement of the main body 1 containing the water when the water in the main body 1 expands and contracts due to the temperature difference between day and night, and when the main body 1 is tilted toward a slope. play.
