Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a method for dividing and planting strip-shaped rush seedlings.

<Prior art> Generally, because the quality of next-generation culms is unstable when germinated seeds are germinated, seedlings that have been transplanted after harvest are harvested after growth and transplanted separately to Honda. For example, by cutting the bottom of the root and the upper part of the culm of a seedling that has grown to a diameter of about 100 mm and dividing it into short culms and manually planting it, or by planting a certain unit of continuous seedlings with rhizomes in advance. A method of planting while mechanically cutting, or a method of planting while straining a plant seedling flatly and mechanically planting it while scraping a large number of stacked pressure strains with a beak, etc. are known.

<Problems to be solved by the invention> However, in general, rush seedlings germinate and grow in a vortex centered on the rhizome in plan view, so the workability of manual cutting of planting plants is poor and the planting becomes uneven. In addition, manual stock splitting is inefficient.

In addition, planting by mechanical cutting has the drawback that a uniform planting plant cannot be obtained due to uneven growth of stem culms, rhizomes and shoots. There are problems such as non-uniformity and damage to shoots.

Other conventional igusa seedlings are not uniform and have non-standard characteristics at the stage of supplying them to the planting machine, which makes handling complicated and results in uneven splitting seedlings and uneven planting as described above. As a result, growth after planting and unevenness of igusa at the time of harvest were brought.

<Means for Solving the Problems> The method of the present invention for solving the above-mentioned problems is a plurality of sheet-like seedlings 1b that are continuous with rhizomes, and strip-shaped by contacting each other at the front and rear adjacent ends. , The strip-shaped connected seedlings 1c rhizomes are joined by a tape-shaped connecting means 29, the tape and each seedling 1b are fixed by suturing or adhesive or other fixing means to form a continuous strip-shaped seedling 1d, The strip-shaped seedling 1d is characterized by being sequentially divided and cut by the amount to be planted.

<Action> The sheet-shaped seedlings 1b become a prototype of the band-shaped seedlings 1d by arranging the front and rear ends thereof adjacently, and by fixing the tape-shaped connecting means 29 along the rhizomes with the fixing means 31 such as a thread. , The whole becomes a band-shaped seedling, and the sprout of the rhizome is also protected by such a connecting and fixing method.

<Examples> Detailed description will be given below with reference to the examples shown in Fig. 2. Fig. 2 shows a pressure biasing method for rush seedlings. The roots of the roots and stems of plants grown to a plant diameter of about 100 mm are trimmed to a total length of about 200 mm, for example. Guide belts 3, which are rotatably and rotatably supported in pairs so as to form the flow passage 2 with a predetermined gap.
Cage-like loosening rotor with multiple longitudinal spokes
4. A pressure bias seedling plant 1b having a thickness of about 20 mm is formed by passing through a pressure biasing device composed of a pressure biasing roller 5.

The seedling 1a is loosened in advance by the basket-shaped rotor 4 as described above, and is softly loosened and flattened without damaging the sprouts sprouted from the rhizome. Pressed to align to final thickness.

FIG. 1 shows a method of forming a band-shaped seedling while connecting the above-mentioned seedlings 1b with other seedlings 1b and an outline of a taping device therefor. The taping device 11 has a long endless surface having irregularities (not shown). Retaining belt 12 to rollers 13,14
A short pressing belt 18 having a front end and a rear end wound around rollers 16 and 17 is supported in parallel with the receiving belt 12 on the front end thereof.

Between the receiving belt 12 and the holding belt 18, the receiving belt 12
On the rear upper surface of the seedling placing portion 18a, the rear end is partially overlapped with or brought into contact with the front ends of the other seedlings 1b to form a gap for feeding forward while pressing the strip-shaped connected seedling 1c sequentially connected. There is.

Each of the rollers 13 and 16 is a driving roller, and the end of each of the roller shafts 19 and 21 has a belt 12,
Pressing rollers 22 and 23, each of which has elastic rubber rubber wound around the peripheral surface that rotates at substantially the same peripheral speed as 18, are axially supported, and in front of the rollers 13, 22 and 16 and 23, pressing rollers are provided. Feed rollers 24 and 26, which feed the seedlings sent from 22,23 while holding them in the next process, are axially supported with a constant gap between the top and the bottom. The feed rollers 24, 26 have spur gear-shaped irregularities formed on their peripheral surfaces, and are both driven in the direction of feeding the seedlings forward.

A guide roller 27 and a tape roller 28 are arranged above and below the pressing rollers 22 and 23, respectively, in a substantially vertically symmetrical manner, and each tape roller 28 has a certain strength against water and a water level. A tape 29 made of paper, cloth, or other material, in which the bond of fibers and the like is destroyed by immersing in a long time, is wound and stocked.

Then, when the continuous seedling 1c sent by the belts 12 and 18 is sandwiched between the pressing rollers 22 and 23 and passes, the upper and lower tapes 29 and 29 are pressed against the pressing rollers 22 and 23 and The adhesive surface side is fed so as to be sequentially adhered to the front and back surfaces of the rhizome of the connected seedling 1c. The root of the rush seedling protrudes from the lower part of the tape 29, and the rush stem part protrudes from the upper part, and the continuous seedling with the tape 29 bonded to the base end is further pressed by the next feed rollers 24 and 26. It is sent out sequentially while strengthening the adhesion.

As described above, at the position where the tape 29 is pressed to reach the next feed rollers 24 and 26, the work of integrally fixing the tape 29 on both the front and back sides and the seedling between them with the thread 31 is performed. Be seen.

That is, around the gap between the front and rear of the rollers 26, 26 and 22, 23 in the moving line of the continuous seedling 1c, tapes 29, 29 and a rotary ring made of a pipe having a center at the seedling portion between the tapes.
32 is provided rotatably at right angles to the moving line.

On the outer circumference of the rotating ring 32, three rolling wheels 33, which are circumscribed at the left and right sides of the lower portion and at the center of the upper portion, are axially supported, and at least one 33a of the lower rolling wheels 33 rotates as a driving rolling wheel. 32 is rotated counterclockwise in rear view.

On the inner circumference of the rotating ring 32, a divider 34 is formed so that its side end facing the rotating direction forms a wedge-shaped edge 34a as shown in the figure, and a divider 34 projects toward the center of the ring.

A yarn reel 36 is rotatably supported in the divider 34, and the yarn 31 wound around the yarn reel 36 passes through a pipe-shaped yarn discharge nozzle 37 attached to the inner end of the divider 34, Roller 2 along with rotation of rotating ring 32
It is fed toward tape 29 between 3,26.

The feeding end of the thread 31 is fixed to the tape 29 between the rollers 23 and 23 and the seedling portion in advance prior to starting the rotating ring 32, and the rotating ring while sequentially feeding the connected seedlings 1c forward.
When 32 is rotated, the thread is unwound toward the center of the ring, and is spirally wound around the tapes 29, 29 on the front and back of the continuous seedling 1c, and the tapes 29, 29 and the igusa seedlings between them are integrally and connected. Then, they are united and fed forward while forming the band-shaped seedling 1d.

At this time, in the illustrated example, the divider 34 rotates upward from below the stem of the connected seedling 1c, pushes the stem portion of the rush to pass through from below, and the thread 31 is blocked by the stem portion of the rush seedling. Without being wrapped around the tape 29 at the root of the seedling, its strength is adjusted by the feeding resistance of the yarn 31 from the yarn reel 36.

As described above, in the method of the present invention, since the yarn is fed by utilizing the forward movement of the seedling and the rotation of the rotary ring 32,
It is not necessary to drive the thread reel 36, and the thread 31
Sufficient winding is possible only by giving the feeding resistance of. In addition, since each of the movements is driven at a constant speed, the winding of the yarn 31 is uniform.

37 is a cutter that is supported on the side of the presser belt 18 and rotates at a high speed, and cut it to a fixed size so as to correct the misalignment of the tips of the connected seedlings that became misaligned at the time of pressure deviation.
Will be the final height dimension.

The belt-shaped seedlings 1d continuously formed as described above are sequentially wound as roll-shaped seedlings 1e as shown by the imaginary line in FIG. 1, and it is possible to directly attach them to the planting machine as they are,
As shown by the solid line in the figure, the strip-shaped seedlings 1f can be used by cutting them into strip-shaped seedlings 1f whose front and rear lengths L are adjusted to an appropriate length. In this case, since the thread 31 is cut at the time of cutting, in order to prevent the thread of the cut portion from being unraveled, a thread stopper tape or a thread stopper 41 with an adhesive or the like is provided in advance to fix the thread 31 of the cut portion to the tape 29. Is desirable.

Next, the case where the band-shaped seedling 1f as described above is planted with a planting machine will be described. The band-shaped seedling 1f is located behind the main body 42 of the riding planting machine as shown in FIG.
And the planting part 47 consisting of the float 46 is connected, and the seedling stand 43
The strip-shaped seedlings 1f are placed in the seedling receiving portion 48 at the upper end in a row in a row. The seedling stand 43 has a shallow angle-shaped (dish-shaped) cross section for accommodating the strip-shaped seedlings 1f in a horizontal manner at the seedling receiving portion 48 at the upper part, but the plane gradually rises as it goes down, and the strip-shaped seedlings at the lower end. It is configured to form a groove-shaped guide portion 50 that guides the 1f upright and guides it downward, and the band-shaped seedling 1f is quantitatively (for example, about 15 mm) by a belt-shaped feeding device (not shown) below. It is a structure that is intermittently fed.

Then, the strip-shaped seedling 1f is cut so that the tape 29 portion of the strip-shaped seedling 1f is clipped from the left and right by the cutter 49 in accordance with the feed amount at the lower end, and the width l (see FIG. 1) is finally obtained. 15
The planted seedling 1g having 12 to 13 stalks in a section of about 20 mm in thickness and 20 mm in thickness is cut off from other plants in sequence, scraped off at the peak 51, and planted at predetermined intervals as the machine runs.

The tape 29 in the above embodiment is preferably adhered to the continuous seedling 1c, but when it is fixed with the thread 31 later, it is not always necessary to adhere and conversely when the tape is strongly adhered with an adhesive or the like, the tape may be on one side. Further, the rotating direction of the rotating ring 32 is the counterclockwise direction in the rear view so that the divider 34 stably pushes the stem portion of the connected seedling 1c from below, but it is also possible to set the rotating direction in the reverse direction. is there.

<Effects of the Invention> According to the method of the present invention configured as described above, since the seedlings have a very stable and regular strip shape, the seedlings are extremely easy to handle and the seedlings are automatically supplied. It is possible to continuously perform automatic cutting and planting by connecting them, improving work efficiency, and making the plant stem positions and number of seedlings of planted seedlings uniform, and making the growth uniform after planting. Also, there are advantages such as ease of management.

Especially for banded seedlings, because the rhizomes are connected and fixed by tape-like connecting means, seedlings can be divided by cutting only the tape and rhizome at the same time, the cutting amount is uniform and reliable, and the leaves and sprouts are damaged. There are few concerns.

Further, since the tape-like connecting means is fixed at the rhizome of the seedling, the fixing is stable, and there is an effect such that slack or looseness does not occur during handling of the band-shaped seedling.
