Abstract

(57) [Summary] [Purpose] A sheet-like heat-generating sheet for growing seeds and seedlings, which aims to promote germination and growth of seeds and seedlings evenly and uniformly in the nursery. [Structure] A sheet heating element sheet A in which a conductive heating paint layer 2 is provided on the surface of a resin base film 1, and electrode patterns 4 and 5 are provided on the heating paint layer.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a sheet-like heating element sheet for growing seeds and seedlings for the purpose of allowing seeds, seedlings and the like to germinate and grow evenly in a seedbed.

[0002]

[Prior art]

 In the fields of agriculture and horticulture, it has been customary to heat the seedbed to a specified temperature in order to germinate seeds and seedlings of vegetables, cereals and flowers, and in general, greenhouses covered with vinyl sheets are used. Inside the house, the room temperature is raised and heating wires are laid on the nursery.

[0003]

[Problems to be solved by the device]

 However, raising the room temperature in the house not only increases the fuel cost because it heats a large house, but the temperature below the ground surface of the nursery does not rise even if it is heated, and the heating wire is installed. The ones installed are effective in raising the temperature below the ground surface, but there is a drawback that there is a temperature difference between the part close to the heating wire and the part far from it, which causes unevenness in germination and seedling growth. there were .

[0004]

[Means for Solving the Problems]

 In order to solve such a conventional defect, the inventors have made earnest researches, and as a result, arrived at the present invention, in which a conductive heating paint layer (2) was provided on the surface of the resin base sheet (1). By laying the sheet heating element sheet A, the temperature below the surface of the nursery ground can be uniformly heated, so that the seedlings can be germinated and unevenly grown, and the growing condition can be made uniform.

Further, by providing the heat-shielding paint layer (3) on the back surface of the resin base sheet (1) provided with the heat-generating paint layer (2), the heat generation amount from the heat-generating paint layer (1) can be reduced. It can be effectively used by being released only upward without being transmitted to the inside.

[0006]

[Action]

 Since the seedling-growing sheet of the present invention has the above-mentioned configuration, it is possible to uniformly heat the grown soil by eliminating the partial temperature difference in the seed-growing soil, and to prevent germination and uneven growth of seedlings. Since this can be prevented, wasteful work of selection and selection after growth can be saved.

【Example】

 Explaining the seedling-growing sheet of the present invention with reference to the attached drawings, FIG. 1 is a sectional view of the seed-growing sheet A shown in claim 1, and FIG. 2 is a cross-section of the seed-growing sheet A ′ shown in claim 2. The figure is shown.

In the figure, (1) is a resin film serving as a base, and (2) is a conductive heat-generating paint layer containing carbon powder as a main material. Further, (3) in FIG. 2 is a heat-insulating paint layer provided on the surface of the base sheet (1) opposite to the conductive heat-generating paint layer, which is obtained by kneading asbestos powder as a main material with a resin binder.

FIG. 3 is an embodiment diagram showing an example of the use of the seed and seedling-growing sheet A of the present invention, in which the copper foil is coated with a conductive adhesive on the edge of the sheet A along the longitudinal direction. The pattern line (4) and the electrode pattern line (5) are provided at a substantially central position along the longitudinal direction. E in the figure indicates a power supply.

Therefore, in the seed and seedling-growing sheet A of the present invention, the conductive heat-generating paint layer (2) generates heat when power is supplied from the power source E, and this sheet A is laid in a nursery bed or cultivated soil. Then, by cultivating the growing soil S on this and energizing it, the heat H is uniformly transferred to the covered growing soil S as shown in the operation example diagram using the seed of FIG. As a result, seed germination can be uniformly and early promoted.

Further, in the case of the heat generating sheet A ′ of FIG. 2, by providing a heat insulating paint layer (3) on the back surface of the heat generating sheet A ′, heat generated from the heat generating paint layer (2) is released to the lower surface. This can further enhance the germination and breeding effect of seeds and seedlings.

[0012]

[Effect of device]

 Since the growing sheet of the present invention has the above-mentioned configuration, it can uniformly heat and heat the growing soil S, eliminate germination of seedlings and uneven growth, and select and select after growing. The waste of

Further, when the seed and seedling-growing sheet of the present invention is used, the sheet is not limited to the above-mentioned embodiment because of its simple structure and can be easily used in a wide range of home gardens. In particular, it has the effect that it can be effectively used in cold regions.
