Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing an embodiment of the drip irrigation device of the present invention. FIG. 2 is a perspective enlarged view showing an injection pipe of the drip irrigation device of FIG. 1. FIG. 3 is a plan sectional view showing an injection pipe of the drip irrigation device of FIG. 1.

As shown in FIG. 1, a drip irrigation device 70 is provided between the reservoir 1 and the plant growing area 12,
The drip irrigation device 70 has a water pipe 2 connected to a reservoir 1. The water pipe 2 has water 2 from the reservoir 1 to the water pipe 2.
A pump 3 capable of flowing 0 is provided, and a water storage tank 5 capable of storing water 20 is connected to the water supply pipe 2. A water supply pipe 5a capable of supplying stored water 20 is connected to the water storage tank 5, and the mixing tank 6 is connected to the water supply pipe 5a.
Are connected. The drip irrigation device 70 has a fertilizer supply tank 7 that stores the liquid fertilizer 21, and the fertilizer supply tank 7 has a discharge pipe 7 a that can discharge the liquid fertilizer 21.
Are connected. The discharge pipe 7a is connected to the mixing tank 6, and the mixing tank 6 is connected to a main water supply pipe 9 capable of supplying the water 20 stored in the mixing tank 6 and the mixed water 22 of the liquid fertilizer 21. There is. The main water supply pipe 9 is provided with a filter 10 capable of filtering the mixed water 22 supplied through the pipe 9, and the main water supply pipe 9 is provided with the mixed water 22 supplied through the pipe 9. There is provided a sterilizing device 11 capable of sterilizing. A plurality of branch pipes 13 are connected to the end of the main water supply pipe 9, and the respective branch pipes 13 are laid in parallel with each other on the plant cultivation area 12. Further, each branch pipe 13 is provided with an injection pipe 14 for each individual cultivated plant 40 adjacent to the branch pipe 13, and the injection pipe 14 is provided for each cultivated plant 40 as shown in FIG. 2. It is connected to the.

The individual injection tubes 14 are, as shown in FIG.
It has a water supply tube 15 further branched from the branch pipe 13, and the end of the water supply tube 15 has flexibility,
A U-shaped tube 16 of U-shape is connected. The U-shaped tube 16 has a water storage space 16a inside,
The water storage space 16a and the water flow passage 15 of the water supply tube 15
It communicates with a. Further, the U-shaped tube 16 is provided so as to surround the stem portion of the cultivated plant 40, and the inner peripheral surface 16 b of the U-shaped tube 16 has a plurality of injection needles 17.
Are provided for the cultivated plant 40. Injection needle 17
The water flow passage 17a of the water storage space 1 of the U-shaped tube 16
6a, and the end 17b of the injection needle 17 pierces the stem of the cultivated plant 40. In addition, the water flow passage 17a of the injection needle 17, the water storage space 16a of the U-shaped tube 16,
The water flow passage 15a of the water supply tube 15 is filled with the mixed water 22 supplied from the branch pipe 13.

As shown in FIG. 2, a second water supply tube 19 is connected to the water supply tube 15 so that the mixed water 22 can be supplied to the soil immediately below the cultivated plant 40.

Since the drip irrigation device 70 has the above-described structure, as shown in FIG. 1, the pump 20 sends the water 20 from the reservoir 1 to the water supply pipe 2 so that the water 20 is stored in the water storage tank 5. You can save it. Further, since the liquid fertilizer 21 is stored in the fertilizer supply tank 7, the water 20 stored in the water storage tank 5 and the liquid fertilizer 21 stored in the fertilizer supply tank 7 are mixed in the mixing tank 6. Therefore, the mixed water 22 including all the nutrients necessary for the cultivated plant 40 can be generated. Therefore, when the mixed water 22 in the mixing tank 6 is sent to the main water supply pipe 9 by using the own weight of the mixed water, the main water supply pipe 9 is provided with the filter 10. Can be filtered by. Further, since the main water supply pipe 9 is provided with the sterilizing device 11, the mixed water 22 can be sterilized. Mixed water 22 passing through the main water pipe 9
Next split into a plurality of branch pipes 13. Then, as shown in FIG. 3, the mixed water 22 flowing into each branch pipe 13
Enters a plurality of injection tubes 14 branched from the branch tube 13.
Then, the mixed water 22 is filled in the water supply tube 15, the U-shaped tube 16, and the injection needle 17 in the injection pipe 14.
Then, the cultivated plant 40 naturally absorbs the required amount of the mixed water 22 from the injection needle 40 stuck in the stem portion. The mixed water 22 that has been absorbed is supplied as described above. Therefore, the mixed water 22 required for the cultivated plant 40 can be directly supplied to the cultivated plant 40. Therefore, the drip irrigation device 70 can supply water to the cultivated plant 40 without any waste. Further, since the mixed water 22 contains all the nutrients required for the plant 40 as described above, the plant 40
Does not require any nutrient or water supply from others. Further, since the mixed water 22 is sterilized by the sterilizer 11 as described above, it is possible to prevent the disease of the plant 40 due to the absorption of the mixed water 22. Also, mixed water 22
Since it is filtered by the filter 10 as described above, it is possible to prevent clogging of the injection needle 17 and prevent the plant 40 from absorbing the mixed water 22. In addition, as shown in FIG.
Since the second water supply tube 19 is connected to the soil directly below the cultivated plant 40 in a form capable of supplying the mixed water 22 to the soil, the mixed water 22 can be dripped onto the soil directly below the plant 40. As a result, the root corrosion of the plant 40 can be prevented. Further, since the U-shaped tube 16 has flexibility, the injection needle 17 can be easily injected into the plant 40 and can be deformed according to the growth of the plant 40.
