2. Description of the Related Art As a continuous collecting pot for transplanting seedlings of this type, a square or hexagonal cylindrical individual pot body formed by expanding a paper or a thin film such as a paper is connected by a connecting piece. There is one in which the continuous body is formed into a body and the continuous bodies are superposed, and the continuous bodies are adhered to each other with a water-soluble adhesive (for example, JP-B-58-11817 and JP-B-4-79612). (See Japanese Patent Publication No. 54-28327). According to such a continuous collecting pot for raising seedlings, a large number of individual pots appear in a honeycomb shape by expanding at the time of use as a pressure-unbalanced state during storage, and the individual pots are filled with cultivating soil. By sowing, many seedlings can be intensively grown. Further, after raising the seedlings for a predetermined number of days and pulling one end, the continuous bodies separated from each other are separated by the use of the water-soluble adhesive, so that individual pots can be continuously drawn out and transplanted efficiently. Like

By the way, seedlings which are continuously drawn out together with the individual pots, so-called continuous pot seedlings, have conventionally been separated and individually planted at a connecting piece portion, for example, Japanese Patent Publication No. 63-63. In Japanese Patent Laid-Open No. 61886, when a connecting piece is provided with a notch in advance and the preceding potted seedling is sandwiched by a rotating transplanting rod and pulled out, the subsequent potted seedling is stopped by a stopper and cut from the notch. However, there is disclosed a transplanter in which the separated preceding potted seedling is planted in the main field by the movement of the transplanting rod. However, such a transplanter is not only complicated and large in itself, but also used by being mounted on a large-scale agricultural work machine such as a riding tractor, which makes it difficult to perform a planting work in a narrow area such as a house. The range of use was limited.

Therefore, recently, in Japanese Patent Laid-Open No. 5-308822, a pot seedling placing portion for placing the above continuous collecting pot,
A sled-shaped body having a potted seedling guide part for guiding the potted seedlings drawn out from the potted seedling placement part in a line and a potted seedling feeding part for feeding continuous potted seedlings one by one from the pot seedling guiding part. There is disclosed a transplanting machine, which is adapted to plant a potted seedling while maintaining a continuous state in a ridge cut open by an opener provided under the machine body according to the sliding of the machine body. According to this transplanter, the sliding body can be pulled by hand or pulled by a walking tractor to continuously pull out the potted seedlings and continuously plant them, and the range of use thereof is significantly expanded.

[0005]

However, according to the conventional continuous collecting pot, the length of the connecting piece is long because of the fact that the continuous bodies are superposed on each other with a water-soluble adhesive so that they can be densely assembled. The width of the individual pots is set to be equal to the width of one face of the individual pots. Therefore, when potted seedlings are continuously planted using the transplanter disclosed in Japanese Patent Laid-Open No. 5-308822, the spacing between the plants is reduced by the connecting piece. There was a problem that the transplantation of crops that were limited by the above and required a wide inter-strain interval became impossible.

The present invention has been made in view of the above-mentioned problems of the prior art, and its object is to reduce the length of the connecting piece as much as possible without sacrificing the dense gathering state of the individual pots. The purpose is to increase the utility value of a transplanter that enables continuous transplantation without dividing pot seedlings.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention connects hexagonal cylindrical individual pots formed by developing a paper or a thin film such as paper with connecting pieces. A polymer obtained by forming a continuous body, setting the length of the connecting piece to 5 times the width of one surface of the individual pot body, and stacking the continuous body so that the individual pot body overlaps the central portion of the connecting piece. As a unit, the plurality of units are laminated by alternately displacing the width across flats of the individual pots, and the individual pots and the connecting pieces are placed between the polymer and the polymer. It is characterized in that it is attached with a water-soluble adhesive.

As a configuration in which they are each provided as a bonded portion bonded with a conductive adhesive, or as shown in Japanese Patent Publication No. 54-28327, a single thin film, and an individual pot body,
It is also possible to adopt a configuration in which a plurality of divided pieces divided by cutting are alternately developed in opposite directions. Further, this continuous body may have a configuration in which the individual pot and the connecting piece are formed separately, and both ends of the connecting piece are adhered to the corners of the individual pot by a water-resistant adhesive.

The present invention does not specify the material type of the above-mentioned thin film, but shall select a material having a rot resistance at least during the seedling raising period. This raising period is generally 4
It is around 0 days, but in the case of long onions, onions, etc., 40-
90 days or more. Examples of the material having a resistance to corrosion for about 40 days include, for example, paper in which a preservative or bactericide is applied to or mixed with plant fiber paper, or synthetic fiber paper in which synthetic fiber is mixed with natural pulp, and 40 to 90. As a material having a corrosion resistance of a day or more, for example, as disclosed in Japanese Patent Publication No. 23640/1990, a synthetic fiber-blended paper is treated with a chemical to increase its wet strength,
A non-corrosive non-woven sheet as disclosed in Japanese Patent Publication No. 59-20325, and a chemically modified paper or a synthetic fiber-blended paper obtained by chemically treating natural pulp as disclosed in Japanese Patent Publication No. 2-6682. Examples include paper treated with antiseptic agents such as germicides.

Further, in the present invention, the kind of the above water-soluble adhesive is also arbitrary, for example, polyvinyl alcohol,
It can be selected from chemical synthetic products such as polyacrylic acid and polyethylene oxide, or natural products such as gum arabic, glue and carboxymethyl cellulose. As the water resistant adhesive, a chemical compound such as polyvinyl acetate emulsion, epoxy resin emulsion and hot melt can be used.

[0011]

In the continuous collecting pot for transplanting seedlings constructed as described above, one unit is a polymer which is superposed so that the individual pots are superposed on the central portion of the connecting piece, and a plurality of units of the individual pots are used. By alternately shifting the positions by the width of two flats and stacking them, the individual pots can be densely assembled without causing any play in the connecting piece set to 5 times the width of one face of the individual pots. . Further, since the individual pots and the connecting piece are attached with a water-soluble adhesive between the polymer and between the polymers, the attached portion is naturally peeled off by irrigation during seedling raising, Potted seedlings can be pulled out continuously with the pieces extended.
