Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a pot body for growing and transplanting seedlings that can be pulled out in a +lI shape by means of a connecting portion made of paper or a thin film such as paper.

(Prior art) Plant seedling transplant cultivation, in which plants are raised in pots made of paper or paper-like thin films and the pot bacteria are transplanted to the field after seedlings, has been widely heard. Various types of pots are known for use in this cultivation, but they can be roughly divided into pots that can be pulled out in rows by connecting individual pots, as exemplified by the Japanese Patent Publication No. 47-51058. The pots are classified into two types: pots that are woven together, and pots that have adjacent parts bonded together using a water-soluble adhesive, as typified by Japanese Patent Publication No. 38-25715.

(The main point while the invention is still trying to solve the problem) ] Regarding the continuous collection pots that can be pulled out in rows and is known from the 2nd year of Jubai, various methods have been made to facilitate mechanical transplantation, but these are connected. A small point is placed on how to divide continuous potted seedlings into individual potted seedlings after growing plants using pots that can be pulled out continuously depending on the section. Although vigorous rooting from the side of the pot body is essential for good rooting of plants after transplantation, it is difficult to root from the side of the pot body in the early stage after transplanting the separated pot body W. No consideration is given to promoting rooting.

The thin film material that makes up the pot is usually selected to prevent the pot from collapsing during the lamp period, or is treated with a certain amount of rot-resistant treatment, so that it will gradually disintegrate over time after transplanting. However, it is extremely difficult to procure or prepare thin film materials that can be applied regardless of soil conditions or field environment. There is a strong desire for a pot body that allows vigorous rooting from the sides of the pot body in the early stage.

(Objective of the Invention) The present invention is directed to the use of pots grown using 100 pots for transplanting that can be pulled out in rows connected by connecting parts; To provide a pot body for transplanting A-seedlings which brings about vigorous rooting from the sides of the pot body regardless of soil conditions and field environment.

(Structure of the Invention) As described above, as a result of intensive research on the pot structure that allows for good rooting from the sides of the pot in the early stage after transplanting, it was found that two sheets of continuous paper or paper-like thin films are arranged at a predetermined interval. In a pot body in which the pot body and the connecting portion are alternately and consecutively bonded to each other with a water-resistant adhesive, the connecting portion connects two sheets of the thin film with a water-resistant adhesive in a direction perpendicular to the longitudinal direction of the thin film. This was achieved by laminating the bonded portions and non-bonded portions in an alternating arrangement. To explain this using an example shown in the drawings, FIGS. 1 to 3 show examples of the pot bodies of the present invention.5 They are normally folded, but when unfolded, the hexagonal column-shaped pot bodies are connected in a row by connecting parts. FIG. 1 is a partial view of the pot body in the unfolded state, and FIG. 2 shows the pot body in the folded state.

In the figure, 1.2 is paper or a paper-like thin film forming the pot body 3 and the connecting part 4, and as shown in FIG.
1.2 are facing each other, their longitudinal side edges are aligned, and a section is made into a non-bonding part 5, and a section β following the division is made into a bonding part 7 using a water-resistant adhesive 6. From now on, in this manner, A strip-shaped body 8 is configured in which non-bonded parts 5 and bonded parts 7 are arranged alternately. In this strip-shaped body 8, the non-bonded portion 5 forms the pot body 3, and the bonded portion 7 forms the connecting portion 4. In addition, if the shape of the pot body shown in the figure is a hexagonal column, the length of the division is approximately I of the pot body 3.
/2 circumference, and section 2 corresponds to approximately 176 circumference of pot body 3.

As mentioned above, the pot body of the present invention is constructed by alternately arranging the non-bonded parts 5 and the bonded parts 7 made of the water-resistant adhesive 6 on the two thin films 1.2. It is characterized by the structure of the connecting part 4 formed by the pasting part 7. The connecting portion 4 is 2
It is formed by laminating two sheets of thin i1.2 with a water-resistant adhesive 6. In this case, a portion 9 not laminated with the water-resistant adhesive 6 is provided, and the pot body 3 is attached via this portion 9. The structure is such that the connecting portion 4 communicates with the connecting portion 4. The lamination with the water-resistant adhesive 6 is done along the boundaries 10 between the sections and the sectional molecules 14), and Figure 1.2 shows a dot array in which the non-bonded portions 9 and the bonded portions 9° alternate. , but is not limited to this, and can be applied in various shapes such as band-like discontinuous lamination (a) as shown in Figure 6, two or more dot array lamination (b), or wavy discontinuous lamination (c). good. The distance between the non-attached part 9 and the attached part 9° does not affect the rooting ability from the side of the pot body 3 after transplanting. Although rooting from the non-bonded part 9 is sufficient, on the other hand, the pot bodies 3. : The radicle of the fungus No. 3 easily enters the non-attached portion 9,
On the contrary, if the spacing is made small, the entanglement of the radicles during the seedling-raising period is suppressed, but in the same way, the entanglement of the radicles from the non-attached portion 9 after transplantation is suppressed. Rooting is also inhibited, a phenomenon that is incompatible with the purpose of this invention. As a result of various studies on the size of the spacing that meets these conflicting demands, we found that the allowable spacing value is 2 to 5ffl.
I got ffl. Reference numeral 11 denotes a separation line provided to facilitate the separation of the connecting portion 4, which particularly facilitates mechanical transplantation work, but there is no particular restriction on its shape.

The pot body of the present invention has a structure in which two thin films are pasted together at regular intervals for a predetermined length using a water-resistant adhesive as described above, and the pot bodies are connected in a row at the connecting portion. The structure of the pot has been specially devised, but as long as it has such a structure, it can be used in any manner.For example, all of the pot bodies from the beginning to the end are connected by a connecting part to create a continuous pot. Examples include a continuous pot body that can be pulled out as a row-shaped pot body, or a collective pot body in which unit bodies formed by a predetermined number of pot bodies connected at a connecting part are stacked in multiple stages.
To explain the former aspect as an example, as schematically shown in FIG. In doing so,
The bonding portion 7-2 of the strip 8-2 is located in the middle of the non-bonding portion 5-1 of the strip 8-1, and the bonding portion 7 is located at the left end of the strip 8-1 in the drawing. A miscellaneous item 12-1 is provided as an extension on the left side of -1, and a water-resistant adhesive 6 is placed on the miscellaneous item 12-1.
is attached, and a water-soluble adhesive 13 is applied to the surface of the strip 8-1 facing the strip 8-2 except for this part, and the strip 8-1 is attached.
Then, in the manner described above, the miscellaneous article 12-2 is extended to the right of the bonding part 7-2 located at the right end of the drawing. A water-resistant adhesive 6 was applied to the upper surface of the strip 8-2, a water-soluble adhesive 13 was applied to the upper surface of the strip 8-2, and miscellaneous items were extended to the left and right ends of the strip 8 in this manner. The strips are sequentially stacked in multiple stages. When this laminate is unfolded, the pot shown in FIG. 4 is exposed, and when this is pulled out from one end, it is pulled out in a continuous form as shown in FIG. Seedlings are raised using such pots, and after seedlings have sprouted, a properly selected transplanter is used to continuously pull them out from one end and separate each pot one by one from the separation line of the joint as shown in Figure 7.
When the bacteria 15 is separated and transplanted to a field, the roots of the bacteria 15 easily enter the non-bonded area 9, encouraging rooting from the tear openings 16 and increasing the rooting of the bacteria 15.

The examples of 1- are strip-shaped bodies 8-1, 8-2, ・-8-n
In this case, the band-shaped bodies 8-1, -
Even if 8-n is a continuum, it is sequentially folded back at the left and right ends so that the bonded part 7-2 is located in the middle of the non-bonded part 5-1 as described above for each predetermined number of pot bodies. However, by applying a water-resistant adhesive to the folded part and a water-soluble adhesive to the other parts, it is possible to construct a continuous row of pot bodies. Figure 8 shows a pot body according to the present invention. Another example is shown, and is a partial view of the rectangular prism-shaped pots 3.3 when they are developed and assembled by connecting them at the connecting part 4, and FIG. 9 is a partial view when the assembly of FIG. 8 is pulled out from one end. It shows a part of a continuous column.

(Example) Example 1 A continuous sheet of paper with a width of 4151 mm is covered with 3 sheets parallel to the paper flow direction.

The connecting part of Ill l Omts is 10 with two glued wires of m.
A water-resistant adhesive (acrylic emulsion adhesive/VII) was applied so as to configure the parts, and continuous paper of the same width was pasted.

Cut this bonded continuous paper at intervals of 130 mm in the machine direction, and cut the left and right sides L1 so that it becomes an L-shaped piece. Apply water-resistant adhesive to both ends of the tube, and also apply water-soluble glue (polyvinyl alcohol adhesive) at right angles to the flow direction in a 10 mm long line.
After this coating, 140 sheets were laminated to form a continuous pot body as one unit.

As a comparative example, we used two glued lines with a width of 3+am constituting the connecting part as the entire surface bonding part (hereinafter referred to as "he9zuke"), and made a continuous set of pots in the same manner as the above boiled set of pots. Manufactured.

The beets were sown in a series of W'c group pots with 9 simmered and 9 simmered pots, and the bacteria were incubated for 40 days. ff tff tI
During the J1 period, no difference in fungal growth was observed between the two types of pots. Furthermore, the bacteria were transplanted to the field and the growth and rooting conditions were investigated after 30E1. The results are shown in Table 1. Both the growth of the plants and the number of roots, the pot body with water-resistant glue on the connection part became the pot body with solid paste. It was found to be superior to other plants, and a special effect on rooting and growth after transplantation was observed.

A water-resistant adhesive (styrene/acrylic emulsion adhesive) was applied so that a connecting part of rll 5 mm was set continuously using two glued lines, and continuous paper of the same type [1] was pasted. This bonded continuous paper was compressed and molded continuously in the flow direction so that the 78 mm portion between the connecting parts became a square, and water-soluble glue (polyvinyl alcohol adhesive) was applied alternately from both sides between each square pot body. After pasting 6 pots with cloth and the 7th pot in a pattern with non-woven fabric, apply water-soluble glue parallel to the flow direction in 16 lines of 8 mm in diameter, 16 folds were laminated while applying one fold and pressure from the non-coated area alternately on the left and right.

After this, the laminate was moved in the machine direction until it was 50+nm thick.
Cut at intervals to make 7 x 16 = 12 pots/unit height 50
A rectangular continuous pot body with a side length of 39 mm was manufactured.

As a comparative example, we made one in which the 212 glued lines that make up the connection part were used as the entire surface bonded part (hereinafter referred to as "sticky").
A continuous pot assembly was manufactured in the same manner as the above-mentioned illuminated pot assembly.

Cabbages were sown in illuminated and covered continuous pots, and seedlings were raised for 25 days. During the 6a fungus period, no difference in the growth of the fungus was observed between the two types of pots. When the seedlings were raised, they were cut from the center of the joint and separated into individual pots, then transplanted to the field and 30 days later, the growth status and rooting status from the pot walls were investigated. The results are shown in Table 2. The pot body with water-resistant glue on the connection part was superior to the pot body with solid adhesive, and a special effect on rooting and growth after transplanting was observed.
