Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an irrigation method for supplying water from a water supply container to a culture soil of a planter, a container, a flowerpot or the like by utilizing a capillary phenomenon of a water supply core.

[0002]

2. Description of the Related Art As one type of this type of watering method, Japanese Patent Laid-Open Publication No. Hei 11-318242 discloses that one end of a water supply core is immersed in water in a plastic bottle, and the other end is buried in a culture soil of a flowerpot. A method of irrigating a flower pot from a plastic bottle using the capillarity of a water supply wick is disclosed.

[0003]

In the above-mentioned conventional watering method, since the middle part of the water supply wick is exposed, water evaporates from this part. Therefore, the amount of water supplied to the culture soil tends to be insufficient, and the amount of water supplied to the culture soil fluctuates because the amount of evaporation of water is affected by the temperature and humidity of the outside air. Recently, the technique of simultaneous irrigation and fertilization, in which fertilizer is dissolved in water to apply fertilizer simultaneously with irrigation, has begun to spread, but it is effective to apply fertilizer to the most active site of the root of a crop. When fertilizing using a conventional watering method, the amount of fertilizer easily accumulates on the water supply wick due to evaporation of water from the exposed portion of the water supply wick. In addition, since the water diffuses into the soil from a portion where the water supply wick first comes into contact with the soil, the fertilizer dissolved in the water is adsorbed on the soil near the contact portion. Further, algae are generated in the water supply wick, and water hardly penetrates. For this reason, it is difficult for the conventional watering method to effectively apply fertilizer to a site having high root activity when a large planter or container is used. The present invention has been made in view of the above problems, and has as its object to provide a watering method capable of providing stable water supply by a water supply core and effective fertilization.

[0004]

According to the first aspect of the present invention, there is provided a culture soil in which one end of a water supply core is immersed in water in a water supply container, and the other end of the water supply core is placed in a planter, a container, a flowerpot or the like. And a water supply method for supplying water to the culture soil by utilizing a capillary phenomenon of a water supply core, wherein an intermediate portion of the water supply core is inserted into a conduit. According to a second aspect of the present invention, in the watering method according to the first aspect, the pipe line is arranged to be inclined in the culture soil so as to be lower at an earlier position. The invention described in claim 3 is claim 1
In the method of irrigation described in 1 above, a belt-shaped thing is used for the water supply core, and a water pipe having a cross section with a flat bottom surface is used for the pipe line. According to a fourth aspect of the present invention, in the watering method according to the third aspect, a rectangular cross section is used for the pipe.

[0005]

According to the first aspect of the present invention,
Since the middle part of the water supply wick was inserted into the pipeline, water evaporates into the outside air from the middle part, diffuses into the culture soil from the part that comes into contact with the culture soil, or evaporates from the middle part due to water evaporation from the middle part. Fertilizer can be prevented from accumulating on the ground. For this reason, stable and uniform irrigation becomes possible. In addition, by burying a conduit in the culture soil and guiding the water supply core, it is possible to irrigate a desired location in the culture soil or to effectively fertilize a site having high root activity of the crop. . According to the invention as set forth in claim 2, since the pipe is arranged inclining in the culture soil so as to be lower as it goes earlier, water sucked up from the water supply container by using the capillary phenomenon is used. And flows to the destination. Therefore, a larger amount of water can be supplied than in the case where only the capillary phenomenon is used, and cultivation using a particularly large planter or container becomes possible. According to the third aspect of the present invention, since a belt-shaped water supply core having a large surface area and a high water supply capacity is used, the amount of water supply can be further increased. In addition, since a pipe having a flat bottom is used, it can be inserted while being spread in a belt shape, and a reduction in water supply power due to contraction or folding of the water supply core can be prevented. According to the invention described in claim 4,
Since a rectangular cross section is used, a strip-shaped water supply wick can be placed on any of the four side surfaces of the pipe as a flat bottom. For this reason, since it is not necessary to pay attention to the direction when installing the pipeline, the piping work is facilitated.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. FIG. 1 shows a watering method according to an embodiment of the present invention. The watering method uses a plastic bottle 10 as a water supply container, and uses the water 11 of the plastic bottle 10 and a fertilizer dissolved in the water 11 to supply water to the culture soil 14 of the planter 13 using the capillary phenomenon of the water supply core 12 to apply fertilizer. I do.

A side surface 10 of a plastic bottle 10 having a hexagonal cross section
The water supply hole 10b is formed in a, and the insertion hole 10d of the water supply core 12 is formed in the side surface 10c. A water amount adjusting hole 10f is formed in the side surface 10e. The PET bottle 10 is placed sideways using the support rod 15 such that the bottom surface is higher than the surface of the culture soil 14. Water is stored in the PET bottle 10 through the water supply hole 10b.
The amount of water stored in the PET bottle 10 is adjusted by adjusting the position where the water amount adjusting hole 10f is formed, or by adjusting the position of the water amount adjusting hole 10f by changing the installation angle of the PET bottle 10.

[0008] The water supply core 12 is a belt-shaped one, one end of which is immersed in the water of the PET bottle 10 from the insertion port, the middle part is inserted into the pipe 20, and the pipe 20 is buried in the culture soil. The other end is taken out from the path 20 and led to a predetermined location in the culture soil 14, for example, in the vicinity of a site having high root activity of the crop.

The conduit 20 includes a U-shaped tube 21, a funnel tube 22, an elbow tube 23, straight tubes 24, 25, 26 and a cross tube 27,
It is formed by connecting 28 rigid pipe materials made of five types of vinyl chloride which do not collapse under the weight of the culture soil 14. All of these five types of pipes are formed so that the cross-sectional shape is rectangular. The portion buried in the culture soil is inclined so that the pipe line 20 becomes lower as it goes earlier.

[0010] One end of the U-shaped tube 21 is inserted into the water inlet 10 d of the plastic bottle 10, the other end is connected to the straight tube 24, and the lower end of the straight tube 24 is inserted into the funnel opening of the funnel tube 22. Since the bent side surface 22a is formed at the funnel opening of the funnel tube 22, the straight tube 24 is inserted and connected to the bent side surface 22a.

An elbow pipe 23 is connected to an outlet of the funnel pipe 22. The elbow tube 23 is formed to have a bending angle of about 110 degrees.

A straight tube 25 is connected to the lower end opening of the elbow tube 23, and a cross tube 27 is connected to the straight tube 25. The cross tube 27 has a structure in which branch pipes 27b are protruded on both left and right side surfaces of a main pipe 27a.
It is shaped to form a degree of bending angle. Further, the straight pipe 26 is connected to the main pipe 27 a of the cross pipe 27, and the main pipe 2 of the cross pipe 28 having the same structure as the cross pipe 27 is connected to the straight pipe 26.
8a. The upstream cross tube 27 is connected such that the branch tube 27b faces upward, and the downstream cross tube 28 is connected such that the branch tube 28b faces downward.

The left and right branch pipes 27b of each cross pipe 27, 28,
The groove-shaped guide frame 29 is inserted into 28b, and the water supply wick 12 is led out of the conduit 20 along the bottom surface of the guide frame 29. A cap 30 is placed over the opening of the main tube 28a of the cross tube 28 on the downstream side.

As described above, in the watering method according to the present embodiment, since the intermediate portion of the water supply core 12 is inserted into the pipe 20, water evaporates from the intermediate portion of the water supply core 12 into the outside air, and the culture soil is The fertilizer can be prevented from diffusing into the culture soil 14 from a portion that comes into contact with the fertilizer 14 or accumulating in the intermediate portion due to water evaporation from the intermediate portion. For this reason, stable and uniform irrigation becomes possible. In addition, a pipe 20
By burying the water and guiding the water supply wick 12, it becomes possible to irrigate a desired location in the culture soil 14 or to effectively fertilize a site having high root activity of the crop.

Also, since the pipe 20 is inclined so as to become lower as it goes forward, the water 11 sucked up from the plastic bottle 10 by utilizing the capillary phenomenon travels down the pipe 20 to the front. Flows. Therefore, a larger amount of water 11 can be supplied than in the case where only the capillary phenomenon is used, and cultivation using a particularly large planter or container becomes possible.

Since the belt-shaped water supply core 12 having a large surface area and a high water supply capacity is used, the amount of water supply can be increased. In addition, since the pipe 20 having a flat bottom is used, the pipe 20 can be inserted while being spread in a belt shape, and the water supply core 12 can be prevented from being reduced due to contraction or folding.

In particular, tubular members 21 to 2 having a rectangular cross section are used.
Since 8 is used, a strip-shaped water supply wick can be placed on any of the side surfaces of the pipe members 21 to 28 as a flat bottom.
For this reason, since it is not necessary to pay attention to the direction when installing the pipeline 20, the piping work is facilitated.

Since the water supply wick 12 is led out of the conduit 20 along the groove-shaped guide frame 29, the water supply wick 12 exposed from the conduit 20 is such that water diffuses into the culture soil 14 only from the upper surface, and the lower surface. Does not spread from Therefore, water and fertilizer easily penetrate to the tip of the water supply wick 12, and water supply and fertilization can be performed over a wide range of the culture soil.

Since the cross pipe 27 on the upstream side is arranged so that the branch pipe 27b faces upward, the amount of water flowing along the branch pipe 27b is suppressed. On the other hand, since the branch pipe 28b of the cross pipe 28 on the downstream side is piped downward, the amount of water diffused from the water supply core 12 exposed from the cross pipe 27 on the upstream side to the culture soil 14 is suppressed. For this reason, water permeates further downstream from the cross tube 27 on the upstream side, so that water supply and fertilization can be performed over a wide range of the culture soil 14.

In this embodiment, the plastic bottle 10 is used as the water supply container. However, the present invention is not limited to this, and a plastic container or the like may be used.
