Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and apparatus for cultivating strawberries, tomatoes, melons, flowers and the like. “Elevation cultivation” is a cultivation method performed on a cultivation floor set at a position higher than the ground.

[0002]

2. Description of the Related Art When harvesting the fruits of strawberry and melon that bear fruit on the ground surface, it is easy for back pain to occur if a crooked posture is maintained. This problem has been exacerbated, especially with the aging of the agricultural population. In order to solve this, elevated cultivation in which the cultivation floor is lifted from the ground and set at a height of about 50 to 150 cm has begun to spread.

[0003] In a conventional cultivation floor, a cultivation sheet supported by left and right support rods, cultivation soil therein, and a water storage sheet provided below the cultivation sheet and water therein are formed. The crops are firmly rooted in the soil and the roots are lowered from the micropores in the soil sheet to the water storage sheet below to absorb nutrients and moisture. Since light is harmful to the roots, the water storage sheet uses a container such as a styrofoam tank or a thick sheet of color (often silver or black) so that the light does not hit the roots in the water storage sheet.

[0004]

The health condition of the crops is almost at a glance when the roots are seen. In the case of the elevated cultivation, the roots are above the ground surface, but the conventional cultivation floor is blocked by the water storage sheet. I couldn't see the root condition directly. Further, in the conventional irrigation management, precision equipment such as a tension meter was necessary because water was not seen because of being blocked by a water storage sheet.

SUMMARY OF THE INVENTION It is an object of the present invention to make it possible to directly observe the growth of roots of a crop in the elevated cultivation with the naked eye and to visually confirm the amount of water.

[0006]

An elevated cultivation apparatus according to the present invention comprises a cultivation sheet supported by left and right support rods, a cultivation medium therein, a water storage sheet provided below the cultivation sheet, and water contained therein. Is characterized in that the water storage sheet is made at least partially transparent and the transparent water storage sheet is covered with a light-shielding sheet that can be opened and closed.

[0007] The elevated cultivation method of the present invention provides a cultivation sheet formed by a cultivation sheet supported by left and right support rods, cultivation soil therein, and a water storage sheet provided below the cultivation soil sheet and water therein. And making the water storage sheet at least partially transparent, using a device formed by covering the transparent water storage sheet with an openable light-shielding sheet, opening the light-shielding sheet and opening the roots and crops of the crop through the transparent water storage sheet. It is characterized by observing the amount of water and closing it again when it is finished.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS It is preferable that the upper end of the light-shielding sheet is buried in the cultivation soil in the cultivation sheet, and the lower end hangs as it is until it reaches the ground. It is preferable that the light-shielding sheet is detachably fixed to the support bar in some places so as not to be blown by strong wind.

If it is uneconomical to provide the light-shielding sheet entirely, the device of the present invention may be provided partially. This is because the purpose of the present invention is to look at the amount of water in the roots of the crop and the water storage sheet, so that sampling is sufficient without looking at the whole.

When the cultivation floor is provided on an inclined ground, the depth of water in the water storage sheet is not constant, so it is preferable to provide partitions at regular intervals.

[0011]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a cross-sectional view and a perspective view of a cultivation bed for elevated cultivation according to a first embodiment of the present invention.

The cultivation floor 1 has a cultivation sheet 5 and a water storage sheet 6 supported by horizontal bars 4 set in parallel along left and right support bars 2 and 3 provided at predetermined intervals. The height of the support rods 2 and 3 is 20 to 30c in the case of tomato cultivation.
m, in the case of strawberry cultivation, it is about 50 to 150 cm.
The distance between the left and right is about 20 to 60 cm. Cultivation sheet 5
And the water storage sheet 6 is held down by the holding metal 7 against the support rods 2 and 3.
It is fixed by.

In the cultivation sheet 5, a cultivation soil 8 is piled, and a crop 9 is planted there. Cultivation sheet 5
Are, for example, those filed by the present applicant (Japanese Patent Application 2000
−217476) can be adopted. In this prior invention, the cultivated soil sheet is woven with fine eyes on the left and right parts,
It was a woven fabric with a coarse weave in the center or a plastic sheet with fine holes in the left and right parts and relatively large holes in the center. The material of the cultivation sheet may be any material as long as it is hardly deteriorated by polyethylene or the like and has heat resistance and cold resistance.

The water storage sheet 6 is set so as to be located about 3 to 10 cm below and farthest from the cultivation sheet 5. In the water storage sheet 6, a certain amount of water 12 containing fertilizers, pesticides, and the like is stored. Therefore, the water storage sheet 6 needs to be strong enough to withstand the weight of water.

A feature of the present invention is that the water storage sheet 6 is at least partially transparent. Preferably, a transparent sheet is used for the water storage sheet 6 over the entire cultivation bed.

Since light is harmful to the roots, the water storage sheet 6
Must be completely covered with the light shielding sheets 10 and 11. The top ends of the light shielding sheets 10 and 11 are
It is buried in the cultivation soil 8 inside, and the lower end is dropped until it reaches the ground. Since the purpose of the light-shielding sheet 5 is only to shield light, any suitable material may be used. It is preferable that the light-shielding sheet is detachably fixed to the support rod in places so as not to be blown by strong wind (not shown).

In the present invention, in order to check the health of the crop, the light-shielding sheet is turned up, and the roots and water are visually observed through a transparent water storage sheet. At the same time, the amount of water in the water storage sheet can be checked, so that the timing of irrigation can be determined. As soon as observation is completed, the light-shielding sheet is lowered and the water storage sheet is shielded again.

FIG. 2 shows a second embodiment of the present invention, in which a cultivation bed is provided on a slope. On a sloping land, the water cannot be maintained at a constant depth in the water storage sheet 6, so the water storage sheet 6 is provided with a partition according to the inclination angle. In this example, a partition is provided by tying the water storage sheet with the string 13. Although not shown, the partition portion can be lifted by a cut-out plate or the like.

[0020]

According to the present invention, it is possible to directly observe the tension of the plant roots with the naked eye just by turning the light-shielding sheet, and to know the health condition of the crop. At the same time, the amount of water in the water storage sheet can be checked, so that the timing of irrigation can be determined. In addition, no special device is required for that purpose, and the water storage sheet may simply be made transparent, and a light shielding sheet may be provided outside the water storage sheet.
