Description

[Detailed Description of the Invention] [Industrial Application Field] This invention is useful for growing seedlings of rice, vegetables, etc., so that the roots of each seedling become pot-shaped seedlings with soil. Regarding the pot-shaped seedling raising device used.

[Prior Art] Conventionally, as disclosed in Special Publication No. IR1 Sho 58-155024, the opening sides of the pots are connected to each other, and the bottom sides with holes are made independent from each other, so that the pot has a rectangular shape as a whole. There was a pot seedling nursery with an array of . In addition, in order to construct a seedling bed using the seedling raising device, it is placed in a seedling raising box with the bottom side with holes facing up, each pot is filled with the floor, and then separate pots are placed. The space between them is also filled with soil. Potted seedlings are grown by sowing seeds in each pot.

[Problems to be Solved by the Invention] Recently, potted seedlings have been attracting more attention due to the growing demand for healthier seedlings. In addition, due to the demand for faster planting operations using transplanting machines such as rice transplanters, it is expected that the accuracy of planting potted seedlings at higher speeds will be improved. This speeding up of planting potted seedlings has brought attention to the accuracy of sending potted seedlings to the seedling transplanting section (transplanting section), which had not previously caused any particular problems in terms of planting accuracy. In particular, unlike mat seedlings, potted seedlings must be sent exactly one bot at a time, so strict precision is required.

In order to achieve this strict seedling feeding accuracy, there were problems with seedlings grown using conventional bot-shaped seedling raisers. In other words, the soil packed between each pot is attached to the left and right ends of the potted seedlings that slide against the left and right side walls of the seedling stand of the transplanter, so when the seedlings are sent, the soil may not touch the side walls of the seedling stand. It was sticky and became a resistance to sending seedlings. As the soil becomes more sticky, the resistance to feeding the seedlings increases, making it impossible to accurately feed the seedlings one bot at a time. The deviation in the seedling feeding pitch disturbs the accurate separation and retention of seedlings by the transplanting device, resulting in problems such as defective transplants such as missing plants.

[Hands & T for Solving the Problem] In order to solve the problem, the present invention has a structure in which the opening 2a sides of the bot 2 are connected to each other, the bottom 2b sides are independent from each other,
In a bot seedling raising device 1 in which bots 2 are arranged in a rectangular shape as a whole, four edges 1a of the outer periphery of the seedling raising device 1,
The seedling raising device is characterized in that a continuous partition wall 3.3 is provided along at least two parallel edges 1a, 1c or 1b, 1d among 1b, IC, and ld.

[Effects of the Invention] When constructing a seedling bed using the seedling raising device 1 of the present invention, first place the seedling raising device 1 on the left and right side walls 12', 12' parallel to the seedling feeding direction C of the seedling stand 12 of the transplanter 11. The seedlings are placed in the seedling growing box 7 so that the partition walls 3.3 of the seedlings are in sliding contact with each other. Then, the floor 4 is packed inside each bot 2, and furthermore, the soil (top) 5 is packed between the independent bots 2.

At this time, since the wall surface of the partition wall 3.3 is in close contact with the inner wall surface of the seedling growing box 7, the top soil 5 does not enter between them. Therefore, even if the potted seedling A grown in this way is taken out from the seedling raising box 7, almost no soil is attached to the outer end surfaces of the partition walls 3.3 at both left and right ends of the seedling A. If the potted seedling A is placed with the end side where this partition wall 3.3 is provided on the side that makes sliding contact with the side wall 12° 12' of the seedling mounting stand 12, conventionally it would be a resistance to feeding the seedlings. Soil no longer adheres or sticks to the side walls 12° and 12° of the seedling stand 12. Therefore, it became possible to smoothly and accurately feed seedlings one bot at a time, and it was possible to improve the accuracy of seedling feeding necessary for speeding up the planting of potted seedlings A.

[Example] An embodiment of the present invention will be described in detail based on the drawings.

1 is a pot seedling grower made of pulp. In this pot seedling raising device 1, small bots 2 are connected in the left and right front and back so that seedlings are grown in a bot-like manner one by one, and are further arranged so that the whole has a rectangular shape.

Each bot 2 is connected to each other at its opening 2a side, and is independent from each other at its bottom 2b side. Further, holes 2C are formed in the bottom part 2b so that the sprouts of the seedlings to be grown can grow. The size of this hole 2C may be expanded to the same size as the bottom portion 2b, so that the bot 2... has a cylindrical shape rather than a pot shape.

3 is a partition wall, and the four edges 1a, 1 of the outer periphery of the seedling nursery 1
b, 1c, 1d (7), two parallel edges 1a,
They are provided continuously along the IC.

The upper side of this partition wall 3.3 is connected to the openings 2a of each bot 2 that are connected to each other, and the lower side is independent from the bottom part 2b where each bot 2 is independent from each other, and is integrally made of the same material as the seedling raising device 1. It is set in. Also, the height of this partition wall 3.3 is the same as the top and bottom height of bot 2 (first
figure). When they are not used for raising seedlings, they are spread out from side to side (Figure 3), and stacked for efficiency during transportation and stocking (Figure 4). At this time, the same number of seedlings are stacked per certain height as in the seedling nursery without the partition wall 3. When raising seedlings, the expanded partition wall 3.3 is used by bending it. In addition, the height of partition walls 3' and 3' was slightly lowered to 3°
If the seedling raising device 1'' is molded into one body with the device bent at 3 degrees (Fig. 5), and can be stacked on top of each other without spreading from side to side (Fig. 7), handling efficiency will be further improved.

4 is bed soil, which is appropriately mixed with ingredients for growing seedlings, and is packed into each bot 2...

5 is soil packed between the bots on the bottom 2b side of each independent bot 2.... This top soil 5 can be used as a medium to properly retain moisture during irrigation during seedling raising, and also as a medium for bot 2...
・Acts as a medium as a nitrogen supply source when the bot 2... corrodes so that the (seedling nursery 1) does not absorb too much nitrogen on the floor as it corrodes.

6 is the seed of the seedling to be grown, 6a is the branch and leaves, and 6b is the root hair.

7 is a seedling raising box, which is just large enough to fit two seedling raising containers 1 side by side. A large number of holes are provided so that excess water from watering during seedling-raising can flow out from the bottom of the box 7.

8 is a riding type rice transplanter, and a four-row seedling planting machine 11 is connected to the rear of a traveling vehicle body 9 via a link 10.

Reference numeral 12 denotes a seedling stand, which is arranged so that the front side is on the upper side and the rear side is on the lower side. It is integrally constructed so that 4 rows of seedlings can be placed side by side on the left and right, and there are 12° side walls that separate each section.
... are provided on the left and right of each article.

Reference numeral 13 denotes a transplanting device, which plants and kills four rows of seedlings in correspondence to the position of each row on the seedling rack 12 on the lower side and rear of the seedling rack 12. This transplant device 13 consists of a rotating case 13a and two implant devices 13b, 13b.

Each of the planting tools 13b and 13b has a seedling separation holding claw 13C1.
13c is attached.

Numeral 14 is a seedling feeding device, which is arranged for each row of the seedling table 12. An endless rubber belt with protrusions hung on a roller allows the transplanting device 13 to feed one row of the lower end of the seedlings placed on each row. Each time the seedlings are transplanted, the potted seedlings A are sent one row further toward the lower transplanting device 13 (seedling feeding direction C). A row of sent seedlings is placed on the seedling stand 12 and transferred to the transplanting device 1.
By moving back and forth from side to side in accordance with the timing of planting one plant at a time in 3, each -bot seedling is placed in the seedling outlet 1.
5, the seedlings are separated and held by the seedling separation and holding claws 13C of the seedling planting tool 13b, and then planted in the field.

To grow potted seedlings A using this seedling raising device 1, first, the partition wall of the seedling raising device 1 should be placed between the left and right side walls 12° and 12° parallel to the seedling feeding direction C of the seedling platform 12 of the transplanter 1. 3 are placed in the seedling growing box 7 so that they are in sliding contact with each other. Then, each bot 2... is filled with bed soil 4, and furthermore, between the independent bots 2... is filled with soil (upper layer) 5 (
Figure 8). At this time, since the wall surface of the partition wall 3 is in close contact with the inner wall surface of the seedling raising box 7, the superior 5 does not enter between them. In addition, an appropriate number of seeds 6 are sown in each bot 2, and then the temperature is appropriately controlled and watered.
The buds 6a and roots 6b grow, and the seedlings are grown (Fig. 9).

Even when the potted seedling A grown in this manner is taken out of the seedling raising box 7, almost no soil is attached to the outer end surfaces of the partition wall 3 at both left and right ends of the seedling A. The end side where this partition wall 3 is provided is the side wall 1 of the seedling stand 12.
If the potted seedling A is placed on the side that makes sliding contact with the seedling table 12, soil will not adhere to the side wall 12'12 of the seedling platform 12 and become sticky, which conventionally caused resistance to feeding the seedlings. Therefore, it became possible to accurately feed seedlings one bot at a time, and it was possible to improve the accuracy of seedling feeding necessary for speeding up the planting of potted seedlings A.

In addition, if it is formed into a seedling raising device 1'' as shown in Fig. 10 and used by folding it into the state shown in Fig. 11,
The rigidity in the seedling feeding direction C of the potted seedlings A'' grown on the partition wall 3''3'' and the partition 3''a becomes stronger, and the lower side of the potted seedlings A'' using the seedling raising device 1'' on the seedling platform 12. This prevents the product from collapsing.

Figure 12 shows the state of raising seedlings using the seedling raising device 1'', with a partition 3” that is bent downward provided in the center of the seedling raising device 1”.
The roots of the seedlings of the bots 2 on the left and right sides of the partition 3'' are intertwined with each other through the holes 3''b... provided in the partition 3'', thereby increasing the integrity of the seedling raising device 1''.
