Abstract

PURPOSE:To hold a seedling in state capable of readily handling and smoothly and certainly planting and transplanting the seedling to a field, by solidifying a number of root parts one by one with a solidifying medium on holding means, taking out one strain at a time together with root part solidifying the above- mentioned seedling and mechanically planting and transplanting the seedling in the field. CONSTITUTION:A solidifying medium obtained by blending soil with lime and water content is poured into a number of pot-shaped hollow parts 1a... formed to flexible thin plate material constituting holding means 1 in process A. The root part 3a of seedling 3 is inserted to hollow part 1a... packed with a culture medium 2 and the culture medium 2 is solidified by drying. Then in the process B, seedling 3 solidifying root part 3a one strain at a time in the process A is taken out from the means 1 and mechanically planted to a field P using a self-propelled transplanter. According to the above-mentioned method, root obtained by division or seedling in the state grown to some extent is collected and held in state capable of readily handling without relatively requiring load and can be simultaneously smoothly and certainly planted and transplanted in the field.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a method for transplanting seedlings, and more specifically, a method for transplanting seedlings obtained by division, or seedlings that have grown to a certain extent, into a field using mechanical force. Regarding the method.

[Conventional technology]

Conventionally, as a method for planting rice grass seedlings using mechanical force,
There is a method disclosed in Japanese Unexamined Patent Publication No. 59-28409, in which divided straw seedlings are inserted into a holding means having a pot-shaped part, and during the second operation, the seedlings are cut out together with the holding means and planted in the field. It is designed to be attached.

[Problem that the invention seeks to solve]

However, in the method cited above, each stem is inserted into a small-diameter opening formed in the pot-shaped part, and the upper end of each stem is widened, so the upper end of the stem must be pinched with fingers during the insertion process. Not only does this require time and effort, but simply inserting the seedling in this way tends to make the posture of the seedling unstable, so there is room for improvement.

Therefore, there is a method of inserting the seedling into the pot-shaped part from the root side, taking out the seedling from the pot-shaped part, and planting it in the field (for example, in Japanese Patent Application Laid-Open No.
8-51722) may be used, but
When using this method, the seedlings may not be stable in the pot-shaped portion, and there is room for improvement in this respect as well.

An object of the present invention is to provide a method for transplanting seedlings so that seedlings obtained by division or seedlings that have grown to a certain extent can be maintained in a state that is as easy to handle as possible, and can be planted smoothly in the field. be.

[Means for solving problems]

The features of the present invention include a first step in which the roots of a large number of seedlings are solidified one by one with a solidifying medium on the holding means, and a first step in which the seedlings on the holding means obtained in this first step are consolidated together with the hardened root portions. It consists of a second step in which the plants are taken out one by one and mechanically planted in the field, and its functions and effects are as follows.

[For production]

For example, if the above characteristics are configured as shown in the figure, in the first step (A), the root part (3a) of the seedling (3) is transferred to the solidifying medium (2).
Since each seedling (3) is hardened with a holding means (1
), the holding posture becomes stable, and the second stroke (
Even in a configuration in which the seedling (3) is taken out and planted in the field (P) in a state where B) is separated from the holding means (1) as shown in the same figure,
The posture of the seedling (3) when taken out is determined to be the desired state,
Moreover, since the shape of the medium (2) of the thinned root part (3a) is not easily lost, the planting arm (10) can be used to securely place the medium (2) in the field (
P).

In addition, since the holding means (1) solidifies the roots (3a) of the seedlings (3) one by one, it does not require the effort of, for example, inserting the stems of the seedlings (3) into a small opening. , seedlings (3
) can be easily separated.

[Effect of idea]

Therefore, seedlings obtained by division, or seedlings that have grown to a certain extent, can be maintained in clusters in an easy-to-handle condition with relatively little effort, and can be planted in the field smoothly and reliably. A method for transplanting seedlings was developed.

〔Example〕

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

As shown in the figure, the present invention has a first step (A) and a second step (A).
The present invention is a method consisting of B), and in the first step (A),
Many pot-shaped concave parts (1a) on a flexible thin plate material...
The holding means (1) is formed with a small diameter through hole (1b) formed at the bottom of the recess (1a). Pour in the solidifying medium (2) consisting of a mixture of water and water, and then pour the root part (3a) of the rush seedling (3) into the solidifying medium (2) in this way.
2) into the concave portion (1a) filled with
The solidifying medium (2) is solidified by drying.

Incidentally, the rush seedlings (3) are obtained by dividing the parent plant grown in the field.

Also, in the second process (B), the root part (3
a) Take out the hardened seedlings (3) one by one from the holding means (1) and mechanically plant them in the field (P) (a self-propelled transplanter shown in the figure is used). .

That is, this transplanter has a transplanting device shown in the same figure, and this transplanting device has a seedling support part (1) that supports the holding means (1).
4), a rod (5) inserted through the through hole (1b) so as to push out a horizontal row of seedlings (3) from the holding means (1) of the seedling support part (4); ), a holding part (6) that holds the seedling (3) pushed out by the insertion of the holding part (6), a swinging arm (7) that supports this holding part (6), and a swinging arm (
7) reaches the swinging posture shown by the imaginary line, the holding part (6
) seedlings (3)..., a comb-like separating member (8);
A conveyor (9) receives the seedlings (3) scraped out from the holding part (6) and sends them laterally, and the seedlings (3) sent by this conveyor (9) are transferred to the claws (10a) of the conveyor (9). Lock it in the field (
Draw a loop-shaped trajectory (S) so as to insert it into the planting arm (10), the swinging arm (7), and the planting arm (10).
), etc., and a transmission case (11) that drives the seedling (3), etc., and the claw part (10a) is connected to the root part (3a) of the seedling (3) during the planting operation.
It is designed to hold the boundary between the solidified medium (2) and the stem.

[Another example]

In the present invention, the holding means can be of any shape, and the solidifying medium can be used in various ways, such as solidified agar or solidified paste, and the seedlings can be used in addition to straw, such as cedar seedlings or Any kind of seedlings, such as vegetable seedlings, can be used, and the work for holding the seedlings in the holding means may be done manually or mechanically.

Incidentally, although reference numerals are written in the claims section for convenient comparison with the drawings, the present invention is not limited to the structure shown in the accompanying drawings.
