Abstract

PURPOSE:To surely and smoothly plant even pot seedling, which is apt to readily collapse caused by contained water by releasing a lower pot material from a pot seedling obtained by superposing pot materials and sowing into the space between upper and lower pot parts and then feeding the pot seedling into an operation locus of planting claw. CONSTITUTION:An upper pot material 1 provided with an upper pot part material (made of paper) 1a is superposed to a lower pot material 2 provided with a lower pot part 2a (made of a resin) and the superposed pot materials are retained in a nursery vessel 4 and seeds are sown in a space between the upper pot part 1a and lower pot part 2a budded from opening 1b to provide the pot seedling P. The lower pot material 2 is released from the pot seedling P downward and then the pot seedling P is fed into the operation locus of planting claw and planted in a field. The pot seedling is free from the shape of collapse even when the pot seedling contains water content, since the lower pot part is made of a resin.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for planting seedlings in pots, and more specifically, the present invention relates to a method for planting seedlings in pots, and more specifically, seedlings that have been germinated and grown in a seedling grower using paper material are held together by planting claws. This invention relates to a planting method in which the planting form is set so that each plant is cut out together with a seedling nursery and planted in a field.

[Conventional technology]

Conventionally, the seedling raising device used when planting seedlings by the above method is made of water-soluble paper material, and in this seedling raising device, a large number of pot-shaped spaces are arranged in a planar manner, and the seedlings are supplied to each pot-shaped space. The seeds are germinated and grown.

In addition, with this type of potted seedlings, the seedlings are planted after they reach the middle or adult stage, so in the mature state, the stems and leaves of the seedlings may become entangled between adjacent seedlings. This may worsen the separation of the plants at the time of planting, and in order to improve the clumping of the plants, there are some seedling raisers with narrowed openings for budding (for example, JP-A-58-
201907).

[Problem to be solved by the invention]

Considering the situation when planting potted seedlings, as shown in the above reference, when planting potted seedlings, place the potted seedlings on a seedling stand etc. Seedlings are cut out one by one from the end using a planting claw.

In addition, when cutting out the seedlings, the seedlings are usually moved laterally across the entire potted seedling with respect to the operating trajectory of the planting claw, and the seedlings are continuously cut out from the lower end of the seedling, so that all the seedlings at the lower end of the potted seedling are cut out. Once this happens, the entire potted seedling is moved downward by one plant, and the seedling is cut out from the lower end in the same way as described above.

However, since these potted seedlings are grown in a water-soluble seedling container, by the time the seedlings can be planted, the seedling container absorbs water and the seedling container itself collapses due to the moisture. This may make it difficult to move the entire potted seedling when planting it.

In other words, the above-mentioned seedling stand is generally equipped with a wheel or a belt that feeds the potted seedlings in the vertical direction (downward), and as mentioned above, the seedling raising device for potted seedlings tends to collapse. When sending the entire potted seedling downward, even if the wheel or belt is driven, the bottom surface of the potted seedling that comes in contact with the wheel or belt will collapse, and the seedlings will only be fed in the required amount. The seedlings may not be fed, or the amount of seedlings fed on the left and right sides may be uneven, resulting in disordered posture of the seedlings.

An object of the present invention is to provide a method for smoothly planting the potted seedlings by reliably feeding the required amount of the entire potted seedlings even if the potted seedlings contain moisture and are easily crumbled.

[Means to solve the problem]

A feature of the present invention is that an upper pot material made of paper having a large number of upper pot parts projecting upward and a lower pot material made of resin having a large number of lower pot parts projecting downward are superimposed two-dimensionally. When planting potted seedlings obtained by sowing seeds in the space formed between the upper pot part and the lower pot part in the field, the lower potting material is peeled downward from the potted seedlings, and then the potted seedlings are The purpose is to feed the planting claw into the operating locus, and its actions and effects are as follows.

[For production]

If we consider the above characteristics as shown in Figures 1 to 3, the potted seedling (P) is dominated by the upper potting material (1) made of paper and the lower potting material (2) made of resin. In other words, since the upper part of the seedling raising device is made of paper and the lower part is made of resin, for example, after a period of time has passed until the potted seedlings (P) reach full-grown seedlings, the upper potting material (1) may be affected by moisture. The lower potting material (2) does not lose its shape even if it is easily crumbled, and when planting potted seedlings (P), feeding force is applied to this lower potting material (2) to ensure that the entire potted seedling is shaped. In addition to being able to move, the potted seedlings (P) are fed into the operating trajectory (T) of the planting claws (8) after the lower potting material (2) is peeled downward, so the lower potting material (2) can move the seedlings. planting will not be hindered.

In addition, this potted seedling (P) has a structure in which the seeds are sown in the space (S) between the upper potting material (1) and the lower potting material (2), so it is possible to plant the seedlings after sowing. After a period of The force acts on all the protruding parts, so the potted seedling (P) can be planted without disturbing the floor.
can be sent in its entirety.

〔Effect of the invention〕

Therefore, even if the potted seedlings contain moisture and have reached a state where they are likely to crumble, a method has been obtained in which the entire potted seedling is reliably planted in the required amount and can be planted smoothly.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

As shown in Figures 2 and 3, a paper upper pot material (1) comprising a number of upper pot parts (1a) projecting upward.
and a lower pot material (2) made of resin, which has a number of lower pot parts (2a) projecting downward, are superimposed two-dimensionally, and a layer is formed between the upper pot material (1) and the lower pot material (2). Seeds are sown in the formed space (S), and seedlings are sprouted through the openings (lb) formed at the protruding ends of each of the upper potting materials (1).
Potted seedlings (P) have been obtained by planting seedlings.

This potted seedling (P) was made with the upper pot material (1) made of water-soluble paper material. As shown in Figure 2, the lower pot material (2) is a film material formed in the form of a groove spanning the entire width in the lateral direction. ) to prevent the stems and leaves from intertwining with each other.
The seedlings are allowed to germinate from the seedlings, and are held in a seedling raising device (4).

When planting these potted seedlings CP), a seedling planting device shown in FIG. 1 is used.

In other words, this seedling planting device is installed in a self-propelled aircraft, and this device includes a chain case (5) to which power is transmitted from the self-propelled aircraft, and a crank driven by the power from this chain case (5). An arm (6), a planting arm (9) that is linked to the crank arm (6) and whose operating locus (T) of its planting claw (8) is set in a loop shape by a swing link (7); A seedling stand (IO) on which a potted seedling (P) is placed, a sliding rail (11) that supports this seedling stand (10) so that it can slide laterally, and a seedling stand (10) placed on the seedling stand (10). Vertical feed mechanism (A) that sends potted seedlings (P) downward.
), and a peeling mechanism (B) for peeling off the lower pot material (2) from the potted seedling (P) when the potted seedling (P) is moved downward by the vertical feeding mechanism (A), At the time of planting, the seedling stand (lO) is moved laterally, and the seedlings (3) are cut out one by one from the lower edge of the pot seedling (P) and planted in the field (12). (system not detailed), from the entire width of the lower edge of the pot seedling (P) to the seedling (3)
When the potted seedling (P) is cut out, the vertical feeding mechanism (A) is operated to feed the potted seedling (P) downward by the amount equivalent to one plant.

In addition, the vertical feed mechanism (A) has upper and lower wheels (13), (13
), the peeling mechanism (B) is formed by winding an endless belt (14) having protrusions (14a) at a pitch equal to the pitch at which the lower pot part (2a) is formed, and the peeling mechanism (B) is made of a curved guide material. (l5), and since the lower pot material (2) is shaped to curve in its natural state as shown by the dashed line in Fig. 2, the potted seedling (P
) is sent downward, the lower pot material (2) is naturally guided to the guide material (l5) side.

Therefore, when planting seedlings, this seedling planting device sends the entire potted seedling downward through the lower potting material (2), so even if the potted seedling (P) contains moisture and is prone to collapse. , feed the seedlings reliably without breaking them, and smoothly grow the seedlings (3
).

[Another example]

In addition to the above-mentioned embodiments, the present invention can, for example, form the lower pot part so as to protrude downward corresponding to each plant from the lower pot material, and It is also possible to create perforations to facilitate downward peeling, and the means for peeling off the lower pot material is to engage hook-shaped claws or the like with the lower pot material. Various implementations are possible, such as constructing a structure that performs forced peeling.

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.
