Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 show a first embodiment of the present invention, in which a black synthetic resin tube 2 is laid in parallel between each row of a large number of rice seedlings 1 in a paddy field. The tube 2 seals and shields the opening 3 at one end and the opening 4 at the other end.
The water of the paddy field is introduced from the inside to fill the inside with water to inflate each tube 2 appropriately, and the other end opening portion 4 is folded and pressed from above with the gate-shaped fixture 5,
Both ends of each tube 2 are sealed. Each tube 2 like this
The opening 3 at one end is shielded, and when water is introduced from the opening 4 at the other end, it is difficult for water to enter the inside, so appropriate small holes 6 are formed at intervals on the outer circumference of each tube 2.

Further, the fixing tool 5 presses the outer periphery of the other end opening 4 of the tube 2 into which the tube 2 is folded at the central portion of the gate shape, and inserts and fixes the tips of both legs into the soil. In this way, each tube 2 is provided with an appropriate number of fixtures 5 at intervals in the longitudinal direction,
These fixtures 5 hold them down so that they do not move in water.
Then, as shown in FIG. 2, each of the above-mentioned tubes 2 is connected to the water 7
It is placed below the surface of the water. In addition, key-shaped fixtures 5a are used at three openings of one end of each tube 2.

If left in this way for a while, the water in each tube 2 is warmed by the sun's rays in the daytime, and since each tube 2 is colored black in particular, it is easy to absorb solar heat and The water temperature rises. Then, at night, the temperature of the outside air decreases and the temperature of the water 7 in the paddy field also decreases. However, since the water inside each tube 2 is sealed, the water temperature does not drop easily compared to the water 7 in the outside paddy field. When this is repeated every day, the water in each tube 2 accumulates heat and is always kept higher than the temperature of the water 7 in the paddy field outside each tube 2. Therefore, the heat of each of these tubes 2 is transferred to the soil below each of the tubes 2, and the soil around the location is always warmed. Then, the soil around the roots of the rice seedlings 1 which are planted adjacent to each other is heated to promote root development.

Further, in the above embodiment, each tube 2 is previously prepared.
When the pesticide is put inside, the pesticide dissolves in water in each tube 2 and gradually comes out from each small hole 6 formed on the outer periphery of each tube 2 into the water 7 of the paddy field outside the tube 2. At this time, the water pressure inside and outside of each tube 2 is constant, and it is considered that the water inside does not come out easily. However, the water in which this pesticide is dissolved has a higher concentration than the water outside, and hence the diffusion phenomenon or Is easily poured out of each small hole 6 to the outside of the tube 2 by osmotic pressure. As a result, the pesticide penetrates into the water and soil around the rice seedlings 1, and the disease of each of these rice seedlings 1 can be prevented. Therefore, compared to the conventional method of putting pesticides in the water of the entire paddy field, they are put only in each tube 2, and these gradually flow out to the surrounding water and act on the plants, so that they are efficient and wasteful. The effects of other biological processes of

When fertilizer is put in each tube 2 in advance as in the case of the above-mentioned pesticide, the fertilizer is dissolved in water in each tube 2, and each tube 2 is passed through each small hole 6 formed on the outer periphery of each tube 2. Gradually go out into the water 7 of the paddy field outside. This allows the fertilizer to penetrate the soil around the rice seedlings 1 and
It absorbs nutrients from roots and promotes growth. Therefore, compared with the conventional method in which the pesticide is added to the water of the entire paddy field, the pesticide is put only in each tube 2, and these gradually flow out to the surrounding water and act on the plants, which is efficient and wasteless.

3 to 5 show an example in which the position of the small hole 6 of the tube 2 in the first embodiment is changed as necessary. In FIG. 3, small holes 6 are formed in the lower portions of the outer periphery of each tube 2, respectively, and water in which fertilizer or the like is dissolved is poured out from each tube 2 near the root of the rice seedling 1. Figure 4
Each of the tubes has a small hole 6 at the center of the outer circumference of each tube 2, and water in which fertilizer or the like is melted is poured out to the surroundings from these small holes 6. Further, in FIG. 5, small holes 6 are bored in the lower center of the outer circumference of each tube 2, and the above-mentioned water does not easily come out from these small holes 6, and therefore it is poured out little by little over a long period of time.

In the first embodiment, each tube 2 is filled with water. However, as in the second embodiment of the present invention shown in FIG. 6, the other end opening 4 of each tube 2 is previously opened and closed by a valve. Introducing pipes 8 that are freely closed and connected to these tubes 2 are provided, and water can be put in and out of each tube 2 from a water source or the like through the introducing pipes 8 by a pump or the like.
Therefore, a sensor such as a pressure sensor is provided in each tube 2, and when the water in each tube 2 is reduced, the sensor detects this, and the valve of the corresponding tube 2 is opened by computer control to operate the pump, Water is supplied to the corresponding tube 2, or the concentration of the pesticide or fertilizer in each tube 2 is detected to supply water in which the pesticide or fertilizer is appropriately melted, the season, month, week, day, etc. It is also possible to control the water to be added to or removed from each tube in a unit cycle.

Further, although the present invention is applied to the paddy field in the above-mentioned first and second embodiments, the present invention is not limited to these and can also be applied to upland cultivation like the third embodiment of the present invention shown in FIG. In this case as well, by placing the tube 2 filled with water between each row of a large number of seedlings 9, the same action and effect as those of the above-described embodiment can be obtained. At this time, the small holes 6 formed on the outer circumference of the tubes 2 can be provided in the same manner as in the above-described embodiment, and the fixing of the tubes 2 is also the same.
