(57) [Summary] (Correction) [Problem] To provide a vegetation bed for hydroponic cultivation, which has good drainage, can promote fruit growth, and can also deal with environmental problems. SOLUTION: The laminated sheet of palm fibers is formed by compression processing to a thickness of 20 to 100 mm suitable for vegetation.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a vegetation bed used for a hydroponic cultivation apparatus for tomatoes, strawberries, melons, papayas, mangos and the like.

[0002]

[Prior art]

 Conventionally, tomatoes, strawberries, melons, mangoes, papayas, and other cultivated plants that have been grown for hydroponic cultivation in a vinyl house are directly accommodated in a longitudinally extending hydroponic gutter in which the nursery pots are housed. Generally, seedlings of the cultivated plant are planted in the plant and the nutrient solution is circulated and grown. As a seedling raising pot used for this purpose, a rock wool pot with good water retention has been mainly used.

[0003]

[Problems to be solved by the device]

 However, while rockwool is excellent in retaining water, it does not drain well, so there is a problem that the sweetness is insufficient in the case of tomatoes, etc., which can be drained well and raised by increasing the sugar content. In addition, when the bed is renewed after cultivation and harvesting, it is difficult to dispose of used rock wool, dust is generated when crushed, and incineration is not possible. It had the disadvantage of having an adverse effect.

The present invention solves the above-mentioned conventional problems, and an object thereof is to provide a vegetation bed for hydroponic cultivation, which has good drainage, can promote fruit growth, and can also deal with environmental problems. .

[0005]

[Means for Solving the Problems]

 As a result of various studies to solve the above-mentioned problems, the present inventor has replaced a rock wool, which has been conventionally used as a bed material on a hydroponic cultivation trough, with a palm fiber laminated plate having a predetermined thickness. We have found a vegetation bed for hydroponics that is extremely desirable in practical use by using a compressed material, and completed the present invention. That is, the present invention is characterized in that it is formed by compressing a laminated sheet of palm fibers into a thickness of 20 to 100 mm suitable for vegetation.

[0006]

[Embodiment of the invention]

 Hereinafter, the vegetation bed for hydroponics of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a perspective view showing an example of a hydroponic cultivation apparatus used in the present invention, and FIG. 2 is a front view and a partial side view showing an example of a hydroponic cultivation apparatus used in the present invention. As shown in this figure, the hydroponic cultivation apparatus 1 is mainly composed of a hydroponic cultivation trough 2, a vegetation bed 3, and a nursery pot 4.

The vegetation bed 3 of the present invention is laid on a longitudinally extending hydroponic trough 2, and a nursery pot 4 is arranged on the upper surface thereof. The vegetation bed 3 is a laminated plate of palm fibers, and the palm fibers are usually natural palm fibers disintegrated with a rope to be returned to a fibrous state, and then placed on a palm array frame and placed on a belt conveyor. Fibers were lined up, needle punched, sprayed with natural rubber adhesive on both sides, dried in a drying oven, vulcanized in a vulcanizer, and then cut into desired dimensions. It is a thing. The thus-obtained palm fiber original plates are widely used as mats, rugs, building materials, etc. by laminating about 6 to 10 of the original plates.

In the present invention, this original plate is used as a vegetation bed, and the thickness of the vegetation bed after compression processing is important, and the thickness before compression processing is in the range of 40 mm to 200 mm. The thickness after compression processing is in the range of 20 to 100 mm, preferably 30 to 50 mm. If the thickness after compression processing is less than 20 mm, the nutrients of palm fiber cannot be supplied to fill the fruit, and if it is more than 100 mm, drainage becomes poor and root growth stops and the sweetness of the fruit is reduced. Can not be increased. For example, in order to compress a laminated plate of palm fibers into a vegetation bed with a thickness of 30 mm, six original plates of palm fibers are laminated to a thickness of 60 mm, and after compression processing, a vulcanized can is used. It may be vulcanized.

Since the vegetation bed of the present invention is made of a natural material, the substances that make up the palm are gradually decomposed by microorganisms by the supplied nutrient solution, which also serves to increase the fiber quality of tomatoes in particular. It can make the stems and leaves strong and firm.

In order to carry out hydroponic cultivation using such a vegetation bed, as shown in FIG. 1, a vegetation bed 3 of the present invention is laid on a gutter 2 and a nursery pot 4 is placed on the upper surface thereof. Then, seedlings of the fruit 7 are planted thereinto, and the nutrient solution is supplied from the injection port 6 of the injection pipe 5. The supplied nutrient solution passes through the seedling raising pot 4, passes through the vegetation bed, and the excess nutrient solution is discharged to the underground nutrient solution tank 8. The seedling raising pot used may be the same material as rock wool or a vegetation bed, or may be rod-shaped and continuous. You may also sow the seeds directly on the bed.

As the nutrient solution to be supplied, two conventionally known culture fluids may be used, and in principle, rainwater or groundwater is used as the water content, and after the water quality analysis, the nutrient solution is blended according to the analysis result. I shall. For this nutrient solution concentration, rainwater is usually analyzed as described above, and then a nutrient solution suitable for the water quality is prepared. The concentration at this time may be set within the range of 5.5 to 7.0 in pH. Further, such hydroponics is usually carried out in a vinyl house, but the room temperature in this house is about 20 to 25 ° C, and in the summer, it may be set to a range of 20 to 35 ° C. In particular, it is preferable to have air permeability.

[Effect of the invention]

 ADVANTAGE OF THE INVENTION According to the vegetation bed of this invention, the fiber and nutrients which palm fiber has can be supplied to a fruit by laying the laminated sheet of the compressed palm fiber in the hydroponic gutter, and fruit growth can be achieved. Since it can be used as a substitute for rock wool, it can provide a vegetation bed that addresses environmental issues that have been emphasized in recent years.
