Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a method for producing seedlings for transplanters.

[Conventional technology]

Conventionally, seedlings such as rush grass are divided into divided seedlings of a predetermined volume and transplanted using a transplanter configured to take out the divided seedlings from a seedling stand and plant them. The seedlings were placed on a seedling stand in their original size, and then divided into predetermined sizes using transplant nails and planted as divided seedlings (for example, Japanese Utility Model Publication No. 85531/1983).

[Problem to be solved by the invention]

In the case of using the above conventional method, when taking out the divided seedlings, the transplanted nails get between the densely planted stems and leaves and split the roots, resulting in problems such as irregularities in the amount of seedlings to be taken out, and problems where the transplanted nails and the transplanted nails are stuck in the stems and leaves. It was easy to cause damage to the seedlings, such as cuts due to contact.

An object of the present invention is to provide a method for producing seedlings for a transplanter, which makes it possible to uniformize the amount of seedlings taken out and to easily obtain seedlings that can be transplanted in a state where damage to the seedlings is extremely unlikely to occur.

[Means to solve the problem]

The characteristic structure of the method for producing seedlings for a transplanter according to the present invention to achieve the above object is to divide a seedling into divided seedlings of a predetermined volume, and to divide these divided seedlings and a non-solid seedling holding material. , the seedling holding material is inserted into the seedling holding recesses arranged vertically and horizontally at set intervals in the plate-shaped seedling bed material, and after this insertion, the seedling holding material is solidified, and the seedlings are transferred between the adjacent divided seedlings by a transplanter. The purpose of this method is to create plate-shaped seedlings so that the extraction and division points are located, and the functions and effects of this configuration are as follows.

[Effect]

a. Seedlings are divided in advance into a predetermined amount of divided seedlings, and the divided seedlings are inserted into the recesses of the plate-shaped nursery material, so that the transplanted nails are arranged in a coarse arrangement with a density that makes it difficult for them to come into contact with the stems and leaves. Seedlings can be neatly arranged at predetermined intervals so that even if they come into contact with each other, they have a retreat space on the side where they can easily bend and retreat so that they are less likely to be damaged.

b When inserting and holding divided seedlings of different sizes and shapes into a recess formed in a predetermined size and shape, the difference between the size and shape of the recess and the size and shape of the divided seedlings Regardless, since the solidified seedling holding material can hold the divided seedlings within the recess for a short time, the divided seedlings are unlikely to shift or come out within the recess.

〔Effect of the invention〕

B. Due to the effect of a. above, the amount of separated seedlings taken out by the transplanted claws is equalized, and it has become possible to provide seedlings that can be transplanted in a state where damage to seedlings and lack of plants by the transplanted claws is extremely unlikely to occur. .

(b) Due to the effect of b. above, once the divided seedlings are aligned in the recesses, there is little risk of them shifting or slipping out of the recesses due to vibrations that occur during transportation or transplanting, and they can be stably held and transplanted with the transplantation nails. This has the advantage that damage and chipping due to contact with other plants are less likely to occur.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

As shown in Figure 1, bottomed holes 1 for holding seedlings are lined up at set intervals in both the vertical and horizontal directions on the surface side using materials such as styrofoam, urethane, urea resin, pulp wood, etc. A plate-shaped seedbed material 2 is constructed.

Then, as shown in FIG. 2, divided seedlings 3 of a predetermined volume are divided from the rush seedlings, and these divided seedlings 3 and gelatinous material such as agar or mud as a seedling holding material are respectively placed in the above-mentioned manner. Insert into bottom hole 1. After this insertion, the seedling holding material is solidified by cooling and drying, and the divided seedlings 3 are connected and held in the arrayed state by the seedbed material 2 that acts on their roots, and then transplanted as shown in FIG. 4, which will be described later. Platy-shaped strawberry seedlings 4 are prepared for transplanting by machine.

That is, the transplanter 5 is configured such that the transplant arm 6 is driven to reciprocate up and down by the link mechanism 7, so that the tip of the transplant claw 8 performs a seedling planting motion in a state where it rotates up and down, and In conjunction with the seedling planting campaign,
The seedling stand 9 is reciprocated and slid in the lateral direction of the machine,
The transplant claw 8 reciprocates the plate-shaped seedling 4 so as to divide the plate-shaped seedling 4 sequentially from one lateral end to the other end by a set width, and the seedling platform 9 moves the plate-shaped seedling 4 at the left and right sliding stroke ends. Each time reaching , the vertical seedling feeder 10 of the seedling table 9 is driven by the set stroke,
The plate-shaped seedlings 4 are vertically fed to the side of the seedling supply port 11 of the seedling platform 9 by an amount corresponding to the set division length in the vertical direction of the seedling platform of the transplanting claws 8, and the descending transplanting claws 8 Accordingly, as shown in FIG. 3, the seedling material 2 is divided at points located between adjacent divided seedlings 3, and the divided seedlings 3 are taken out one by one from the plate-shaped seedling 4 together with the divided seedling material portion 2a. It is planted in the field.

[Another example]

As the seedling bed material 2, as shown in FIGS. 5 and 6, the seedling holding holes 12 are also opened on the back side of the seedling bed material 2, or as shown in FIGS. A method in which the hole 1 or 12 is formed in a shape that becomes smaller in diameter toward the back side, or a sixth method
As shown in FIG. 7 and FIG. 7, a method may be adopted in which the dividing portion by the transplanted nail 8 is made thinner by cutting on the back side to improve the dividing property.

In the present invention, the bottomed hole 1 and the through hole 12 are collectively referred to as the seedling holding recess 1 or 12. Furthermore, the present invention can be applied to the production of various seedlings for transplantation, such as cedar seedlings, in addition to rush seedlings.
