Description

[Detailed Description of the Invention] (Industrial Application Field) This invention is a method of connecting and assembling a large number of pots made of a piece of paper or a thin film like paper in order to grow seedlings with soil in units of planted plants. Seedlings can be raised by filling soil in a group pot for seedling raising and transplanting, or the seedbed itself, which is made up of a sponge-like synthetic resin seedbed, forms a pot and many of these are connected to form a group pot. The present invention relates to a method for raising seedlings by providing rectangular hollow bodies constituting space rows between the rows of pots to substantially expand the area of each pot.

(Prior Art) Conventionally, containers for raising and transplanting rice seedlings such as paddy rice, rapeseed, and tobacco have been made by connecting a large number of paper pots with no lids and bottoms to form seedling containers, or by using sponge-like synthetic resin seedbeds. There is no container for raising seedlings so that each plant can be separated.

Another method used is to raise transplanted seedlings.

The individual pots that make up these collective pots vary in size depending on the crop to be raised, the period of seedling raising, etc., but in order to obtain larger transplanted seedlings, it is necessary to create a suitable medium capacity. Seedlings must be grown using pots of the same size.

In addition, in cold regions where the cultivation period is short, it is important to grow healthy large seedlings with an advanced number of leaves for all crops such as paddy rice and side dishes. The key is to let the seedlings grow, and for that purpose, it is desirable that the seedlings are at an advanced age at the time of planting, and the quality of the seedlings should be 3 to 3.5' from the original seedling age of around 2.5 leaves! J
The trend is to gradually grow larger seedlings, from medium-sized seedlings to mature seedlings with 3.6 leaves or more, and use them as transplanted seedlings.

(Problems to be Solved by the Invention) As a means of raising adult seedlings, it is best to expand the growing area per unit of seedlings in the nursery, increase the amount of medium per unit of seedlings, and extend the period of seedling raising. This is a major factor, and the best method is to reduce the amount of seeds per seedling container. Therefore, in order to obtain mature seedlings, it is essential to increase the size of the pot and increase the area and capacity of each individual seedling. This not only imposes an increased burden, but also has a significant negative impact on work efficiency.

(Means for Solving the Problems) As a result of various studies on seedling raising methods that can use clustered pots that do not have the above-mentioned drawbacks, the present inventor has found that during seedling raising, a rectangular or hexagonal pot is placed in a square or hexagonal shape using non-perishable paper or a thin film like paper. A collective pot for raising and transplanting seedlings, comprising a hollow cylindrical pot body, a predetermined number of pot bodies connected in series with a water-soluble glue, and a predetermined number of rows of pot bodies laminated and adhered with the same water-soluble glue. When raising seedlings using a container, a gap is formed between each row of pots by a rectangular hollow body having approximately the same length and height as the row of pots, which is composed of an upper surface of a predetermined width and four circumferential sides. As a result, it was possible to expand the growth area of each planted plant and obtain large seedlings by growing the seedlings for about 40 days, which is the normal period for growing seedlings. This rectangular hollow body is in a cluster pot body that is easily separated when transplanting.

By pasting paper or a paper-like thin film that easily rots easily during the seedling-raising period between the rows of pots during the production of group pots, the hollow bodies will rot and disintegrate during transplanting due to watering during seedling-raising. Therefore, the transplanting operation using a transplanter can be performed in the same manner as for transplanting a group pot body without a hollow body.

In addition, a connecting piece is provided between each pot body of the group pot body to form a continuous pot body, and in the case of a group pot body that is continuous from one end to the other end, a hollow body is provided between each row of pot bodies as described above. They may be attached in advance, but once the rows of pots are in continuous clustered pots, once the seedlings are raised, the rows of pots will easily separate due to overflowing water, so create gaps by installing hollow bodies between each row during seedling raising. ``A Qualitatively, after expanding the seedling growing area of each pot and growing the seedlings to obtain large seedlings, at the time of transplanting, the hollow bodies are removed and each row of pots is compressed to perform the transplanting work as a group of pots.

Furthermore, even if there is a grouping pot for raising and transplanting seedlings, which is a grouping pot made of sponge-like synthetic resin seedbeds connected together so that each plant can be separated, after 71 seeds have been brought into the seedling-raising state, the pots can be placed in rows. By installing a rectangular hollow body in between, the area for growing seedlings can be expanded and large seedlings can be grown.

The width of the rectangular hollow body used in the method of this invention is appropriately determined depending on the type of crop, the diameter of the pot body, etc., but it is usually 2 m or more in width and about 175 to 3 times the width of each pot body.

(Function) As shown in the drawings, the pot body 1, which is a hollow cylinder, is made of paper 1, such as kraft paper treated with antiseptic processing, or a thin film of synthetic fiber paper, etc., which does not rot during the seedling-raising period. These pot bodies 1 are glued in series with water-soluble glue to form one row of pot bodies.Next, one row of pot bodies is laminated and pasted in a predetermined number of stages to form a collective pot body 3. A rectangular hollow body 2 made of paper 9, which easily rots during the seedling-raising period, for example, kraft paper that has not been treated with anti-corrosion treatment, is inserted into the pot with a cross-sectional top surface of a predetermined width and four circumferential sides approximately at the same height as the pot body 1. If it is pasted with water-soluble glue, stored in a folded state, and unfolded when used, a hollow body 2 of a predetermined width will always appear on the side of one row of pots, and the hollow body 2 will be placed in the seedling box 4. Even if the pot body 1 is installed and filled with ±5 seedlings for raising seedlings, the hollow part of the hollow body 2 is maintained as it is, and the state of growing seedlings with an enlarged growing area can be maintained.

In addition, in the case of a collective pot body 13 in which pot bodies 11 are connected by connecting pieces 15 as shown in FIG. 4, the rectangular hollow bodies 12 do not need to be attached between the rows when the collective pot body 13 is manufactured.

After the seedlings are raised, the rows of group pot bodies 13 are easily separated and expanded, so rectangular hollow bodies 12 made of synthetic resin 12fJI boards are successively inserted and installed in this gap to expand the seedling growing area of each pot body 11. It can be done.

Furthermore, when these pot bodies 3 and 13 are transplanted, the rectangular hollow bodies 2 and 12 between the rows of pot bodies 1 and 11 are removed and the gap between them is compressed and placed on a transplanting machine. By raising the seedlings in a seedling raising box 14 with a perforated bottom of the pot bodies 3 and 13, roots extending downward from the perforated part can be easily cut off before removing the hollow bodies 2 and 12.

(Example) Details will be further explained below using examples.

(1) Paddy rice test 1 A square front pot body 1 with a side of 14 mm and a height of 28 m was constructed using vinylon mixed kraft paper with a tsubo t + t 60 g/rrf as rot-resistant paper, and one side of this pot body 1 was Water soluble 1) V
A 10% aqueous solution of A-205 (trade name, manufactured by Kuraray Co., Ltd.) was applied, and 20 pot bodies were sequentially arranged into one row of connected pot bodies.

Next, 38 rows of pot bodies are laminated and pasted together to form a collective pot body 3. At this time, between each row of pot bodies, a reprinted kraft paper with a basis weight of 50 g/rrr is used as paper that rots easily during the seedling-raising period. A rectangular hollow body 2 having a length of 280 m, a height of 28 nm, and a width shown in Table 1 was formed using the following method, and the hollow body 2 was inserted and pasted.

Next, set each group pot 3 to 11i, and add Yf seedlings ±5 to each pot 1.
Filling,! ! Three grains of paddy were sown in each pot 1, and a seedling-raising underlay paper, Kurapuppy (trade name: Kuraray Co., Ltd. 12), was placed on a platform to raise seedlings.

The results are shown in Table 1.

Table 1 (Note) Width 03 of NQI's hollow body is a control example of a conventional collective pot that does not use a hollow body between one row of pots.

As shown in the table above, each pot 1 in which two hollow bodies not filled with seedling soil 5 were provided between each row of pots was compared to the control pot 1 in which two hollow bodies were not provided. Even though the amount of seedlings produced and the number of days for raising seedlings are the same, there is a noticeable difference in the growth performance in terms of number of leaves and dry weight, and if a hollow body 2 with a width of 6 parts is provided, seedlings can be raised for about 35 days. So, 3.6
It can be grown as an adult seedling with leaves. In this way, when transplanting the cluster pot body 3 with the two hollow bodies that have been grown to full-grown seedlings, the two hollow bodies rot and can be easily dismantled and torn apart. Push toward the center from both ends, fold the two hollow bodies between the rows of pots, and bring each row of pots into close contact with each other.
The 35-day-old seedlings were placed on a rice transplanter and subjected to mechanical transplantation.

Both the length and width are the same as a conventional assembly because the two hollow bodies are compressed, and the weight is also ¥100. [±5 was the same company, so there was no change, and the porting work was carried out without any trouble.

(2) Paddy rice test 2 The base paper for the pot bodies 11 was the same as in Example 1, and a hexagonal cylindrical pot body 11 with a diameter of 1°8 parts m and a height of 3.0 parts m was formed. As shown in FIG. 4, a connecting part 15 made of paper of the same quality as the paper on which the pot body 11 was formed is provided between each pot body 11.
A pot body 13 made of continuous paper tubes was constructed by connecting 720 continuous paper tubes.

Expand this and fill each pot 11 with ±5 seedlings, each pot 11
Sow 3 rice seeds (variety Kitahikari) on a plate and place on a seedling-raising underlay paper Kurapabi (product name: manufactured by Kuraray Co., Ltd.)
Seedlings were raised by placing the seedlings on top of the bed. 14 days after sowing, when two leaves have developed, the pot body 13 is placed in a separate seedling box 14 (inner method 28) with holes for root elongation in the bottom.
tya Seedling cultivation continued using the hydroponic method as shown.

V1 seedlings grown using the hydroponic method are placed in a molded plastic tank 17 equipped with a water level control valve (not shown), and the water level of the nutrient solution 18 is intermittently raised to point A in Figure 5, and then gradually as the roots elongate. While lowering the water to points B and C, the water level was maintained such that the water level was constantly present in the nutrient solution 18. Yf! During the period, the temperature of the culture solution 18 was 15 to 25°C, and the pH was 4.5 to 5.5 with H, SO4, and KOH. E, C ('l air conductivity) is 1,5 ~
It was controlled within the range of 2.0 m s/csa.

When the culture solution 18 decreased, a new culture solution 18 was prepared and supplied. The solution was made to have a dissolved acid concentration of 146.6 ppm (at 25° C.), which was 80% of the saturated state, using a continuous circulation method. The composition of this culture solution 18 was as follows throughout the period. (Unit: ppm) N 60. P, 0. 30. To, 0 120. CaO

o0.01, results as shown in Table 2 were obtained on the 35th and 42nd day of seedling raising.

(Margins below) Table 2 (Note) Mal is the control side where the hollow body 12 is not used.
In the table as well, the pot 11 with 12 hollow bodies provided between each 11 rows of pots has 12 hollow bodies provided between each 11 rows, compared to the pot 11 without 12 hollow bodies in the control example, while having the same seedling attendance and number of seedling raising days. There is a remarkable difference in the growth rate both in the number of leaves and in the above-ground dry matter.If 12 parts of 2-inch-wide hollow bodies are provided, 11 seedlings can be grown in about 36 days, and 3.8 'tR
It can be grown as an adult seedling.

At the time of transplanting the cluster pot body 13 provided with the hollow body 12 that has been grown into a mature seedling in this way, the roots extending from the perforated bottom part of the seedling tray are cut off, the hollow body 12 is removed, and the cluster pot body 13 is
Push it to one end so that the 11 rows of each pot body are in close contact with each other.
The rice transplanter was placed on a special rice transplanter for 35-day plots in February 2, 2015, and subjected to mechanical transplantation, but the process was carried out in the same way as with conventional group pots without any trouble.

(3) Lettuce Test 1 The same base paper as in Example 1 was used as the rot-resistant paper constituting the pot body 1 and the paper that easily rots during the seedling-raising period to form the two hollow bodies. The size of the pot body 1 is 201 square x 301 high according to Niratin paper pot standard 5M2406 (product name Nippon Beet Sugar Co., Ltd.).
VA-205) i: When 14 i" pieces are connected and pasted to form one row of pot bodies, and these are laminated and pasted in 29 stages.

Two rectangular hollow bodies with a top surface of 10 square meters and a height of 30 square meters and a length of 280 square meters were inserted and pasted between one row of each pot body. Next, this collective pot body 3 was unfolded, and the field soil was sieved at 5 m, and N, Pa1
300 ppm each of M and KaO were added and filled into each pot body 1 from above. At this time, since the upper surfaces of the two hollow bodies are closed, a hollow part having a width of 10 square meters is maintained between each row of pot bodies into which soil is to be placed. Each pot body 1. Lettuce seeds (variety: Ballard) were sown in two batches, and after 15 days, the seedlings were thinned out and grown as single plants for 45 days.

The transplanting work was done manually, but because of the two hollow bodies placed between each row of pots, there was no intertwining of the leaves between adjacent rows, and even though the seedlings were larger than conventional seedlings in group pots. The porting work went very smoothly.

(4) Lettuce test 2 A strip-shaped synthetic resin sponge culture medium (2°3a1 square x 2.aam height, 300 continuous sticks) with slits provided in the seedbed so that each plant can be separated was used in Example 2. Leaf lettuce (
Variety Green Wave) was sown.

Following the hydroponic method in Example 2, the nutrient solution 18 is supplied from the lower part of the seedling box 14 to raise the seedlings for 10 days, and then the rows of each seedbed block are separated to create the spacing between the rows of blocks of each size shown in Table 3. A hollow body 12 made of a thin plate was inserted and installed, and the seedlings were continued to be raised as they were, and the seedlings were planted on a 20-day scale.

Table 3 shows the results regarding seedling quality at the time of planting and yield by period after planting in the field.

Table 3 (Note) Nal is a control example in which the hollow body 12 is not used.

The transplanting work was done manually, but in the plots with 12 hollow bodies, the wider the hollow bodies 12 were, the larger the seedlings could grow, and the planting work could be carried out smoothly without the leaves intertwining with each other. The time of accumulation was also significantly earlier than that of the control.

This makes it possible to easily grow mature seedlings without changing the seedling-growing conditions such as the seedling-raising period while suppressing the increase in the amount of filled seedlings produced.Furthermore, for paddy rice, it can be used in a rice transplanter in the same way as a conventional group pot. It is said that it can be done sexually.

In addition, when used for field crops such as lettuce, cabbage, and Chinese cabbage, conventional clustered pots often cause the stems and leaves to get entangled between adjacent pots, worsening workability. This prevents entanglement while producing large seedlings.
