BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet for cultivating agricultural crops such as beans and strawberries which blocks sunlight and lowers the soil temperature, thereby promoting germination of the agricultural crops.

[0002]

2. Description of the Related Art In the cultivation of agricultural products such as beans and strawberries, it is preferable that the ground temperature at the time of germination be low to some extent. Therefore, conventionally, a method of lowering the soil temperature by blocking the sunlight using a long sheet has been taken, and this has contributed to promotion of germination of crops. That is, as shown in FIG. 3, a long sheet 11 provided with a plurality of holes 16 is laid so as to cover the entire ridge 21 of the field, and seeds such as beans and strawberries are laid in the soil exposed in the holes 16. Are planted, germinated and cultivated.

The structure of the long sheet 11 is shown in FIG.
As shown in FIG. 2, basically, the PET film 12, the aluminum vapor deposition layer 13 formed on the top surface of the PET film 12, and the fusion resin layer 14 of polyethylene are fused to the top surface of the vapor deposition layer 13. And a polyethylene resin cloth 15 made of polyethylene.

[0004]

[Problems to be Solved by the Invention] However, since the conventional long sheet 11 is mainly composed of a synthetic resin such as PET film or polyethylene cloth, it is decomposed or weathered by rainwater or microorganisms. There is nothing to do. Therefore, after harvesting the crop, the above-mentioned sheet has to be wound up and collected, which requires a great deal of labor.
In addition, when the collected sheet is burned for disposal, a harmful gas is generated due to the composition mainly of the synthetic resin, which causes a problem in the destruction of the natural environment.

[0005]

The present invention has been made in view of the above-mentioned problems of the prior art, and its object is a sheet for promoting germination of agricultural crops such as beans and strawberries. In addition, a sheet that does not need to be recovered after harvesting a crop and has low pollution is provided.

In order to achieve such an object, the sheet of the present invention is basically formed on a base paper, a sealing coat layer applied on the upper surface of the base paper, and an upper surface of the sealing coat layer. A sheet for promoting germination of an agricultural product, comprising a metal vapor deposition layer and a surface coating layer applied on the upper surface of the vapor deposition layer.

Further, the seat of the present invention, if necessary,
The sheet is characterized in that a plurality of holes are provided in the sheet so as to be separated from each other.

As described above, the sheet of the present invention comprises paper, an aluminum vapor deposition layer and two thin resin coat layers,
Among them, the paper and aluminum vapor deposition layer are decomposed and weathered by rainwater, microorganisms, and the like. On the other hand, the two resin coat layers are not decomposed or weathered, but the resin of the coat layers is contained in the sheet in an extremely small amount. Therefore, even if the sheet of the present invention is laid on a field ridge and used, and then the field is cultivated as it is without being recovered, the sheet mixed with the field soil will be almost completely decomposed and weathered by rainwater or microorganisms. .

That is, the sheet of the present invention can be used as a germination promoting sheet with low pollution.

[0010]

The sheet for promoting germination of agricultural products of the present invention will be described below in more detail with reference to the accompanying drawings.

FIG. 1 is a partially enlarged sectional view of a germination promoting sheet of the present invention, in which 1 indicates the sheet of the present invention as a whole. The sheet 1 is basically a base paper 2, a sealing coating layer 3 applied on the upper surface of the base paper 2, an aluminum vapor deposition layer 4 formed on the upper surface of the sealing coating layer 3, and an aluminum vapor deposition layer 4.
And a surface coat layer 5 coated on the upper surface of the. As shown in FIG. 3, the sheet 1 is provided with a plurality of holes 6 for planting seeds such as beans and strawberries so as to be separated from each other in the longitudinal direction of the ridges 21 as necessary. .

The base paper 2 used in the above-mentioned sheet 1 thus constructed may be any paper having a proper strength as a germination promoting sheet, such as tamarafu kraft, high quality paper,
Paper such as art paper can be used, and its thickness is preferably about 50 to 200 μm in view of the above-mentioned strength. The sealing coat layer 3 must be one that smoothes the surface of the base paper 2 in order to uniformly deposit aluminum on one side of the base paper 2. Therefore, AC varnish P-3060H (manufactured by Dainichiseika Co., Ltd.) for vapor deposition of aminoalkyd resin is suitable as the sealing coat layer 3, and urethane resin or vinyl chloride-vinyl acetate copolymer resin can also be applied. It is preferable that the thickness is about 3 to 4 μm.

The aluminum vapor deposition layer 4 reflects the sunlight hitting the ridges to lower the ground temperature of the ridges, and other metal vapor deposition layers are also applicable. Further, the surface coat layer 5 must be one that covers the surface of the vapor-deposited layer and prevents the oxidation of aluminum in order to prevent the vapor-deposited aluminum layer from being oxidized and lost by rainwater or the like. Therefore, Dencarac # 21K (manufactured by Denki Kagaku Kogyo Co., Ltd.), which is a vinyl chloride-vinyl acetate copolymer resin, is suitable as the surface coating layer 5, and is made of polyamide, acrylic, polyester, nitrified cotton,
Alternatively, a shellac resin can be applied, and the thickness thereof is preferably about 1 to 2 μm.

As a method of manufacturing the sheet 1,
Base paper 2 is coated with amino alkyd resin on one side by gravure method or kiss method.
Aluminum may be vapor-deposited on the sealing coating surface by a conventional method, and the surface of the aluminum vapor-deposited surface may be coated with a vinyl chloride-vinyl acetate copolymer resin by a gravure method or a kiss method.

Further, as a method of using the seat 1 of the present invention, as shown in FIG. 3, like the conventional seat, the seat 1 is laid so as to entirely cover the ridge 21 of the field, and Seeds such as beans and strawberries may be planted in the soil exposed in the plurality of holes 6 and germinated. The sheet 1 reflects sunlight by the aluminum vapor deposition layer 4 to lower the ground temperature of the ridges, thereby promoting germination of agricultural products. Then, the agricultural product grows at the plurality of holes 6, and after the agricultural product is harvested, the sheet 1 may be left without being collected, and may be cultivated together with the soil when the field is cultivated.

Here, after the crop is harvested, the base paper 2 and the aluminum vapor deposition layer 4 of the sheet mixed with soil are decomposed and weathered by rainwater, microorganisms, or the like. On the other hand, the portions of the sealing coat layer 3 and the surface coat layer 5 are not decomposed or weathered by rainwater or microorganisms, but the amount itself is extremely small. That is, the sheet 1 of the present invention as a whole is a sheet that is almost completely decomposed and weathered by rainwater, microorganisms, etc. Therefore, it can be said that it is low pollution even if it is left in the field without being recovered after use.

Even if the sheet of the present invention is burned in the field for disposal after use, no harmful gas is generated because the sheet is mainly composed of paper and an aluminum vapor deposition layer. That is, it can be said that the sheet of the present invention has low pollution even if it is burned and disposed of in the field after use.

[0018]

[Effect of the Invention] According to the sheet of the present invention, since the sheet is mainly composed of paper and an aluminum vapor deposition layer, it is almost completely decomposed and weathered by rainwater or microorganisms.

Therefore, the present invention is an extremely excellent device which has various excellent effects as described below.

Since the sheet of the present invention is almost completely decomposed and weathered by rainwater, microorganisms, etc., it does not need to be recovered even when it is no longer needed after use, and it is possible to save much labor for recovery. Also, it has low pollution even if left in the field.

Further, since the sheet of the present invention does not generate much harmful gas even when burned, it has low pollution even when burned and disposed of in the field after use.

Furthermore, since the aluminum vapor-deposited layer of the sheet of the present invention reflects light, oil insects that hate light and insects that eat leaves are not attached to agricultural products. That is, the sheet of the present invention makes it possible to prevent pests that hate light from becoming more visible.
