Description

TECHNICAL FIELD The present invention relates to a method for planting pot seedlings, and more specifically, seedlings sprouting and growing in a seedling growing device made of paper material are planted one by one by a planting claw. The present invention relates to a planting method in which the planting form is set so as to be cut out together with a seedling raising device and planted in a field.

[Conventional technology]

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

In addition, in this kind of pot seedling, since the seedling is used for planting after reaching a middle seedling or an adult seedling, in the grown state, the stems and leaves of the seedling are entangled between adjacent seedlings. ,
There is also a case where the separability of the strain at the time of planting is deteriorated, and conventionally, in order to improve the cohesion of the strain, there are those in which the opening for emergence in the seedling raising device is narrowed (for example, JP-A-58-
201907 publication).

[Problems to be Solved by the Invention]

Here, considering the situation at the time of planting pot seedlings, when planting this kind of pot seedlings, as shown in the conventional example, the pot seedlings are placed on a seedling stand or the like. Seedlings are cut out one by one from the edge of the seedlings with planting claws.

In addition, at the time of this cutting, the whole pot seedling is moved laterally with respect to the operation locus of the planting claws, and the seedlings are continuously cut laterally from the lower end of the seedling so that all the seedlings at the lower end of the pot seedling are removed. When cut out, the pot seedlings are moved downward by one whole and the seedlings are cut out from the lower end portion of the seedlings as described above.

However, since this pot seedling is grown in a water-soluble seedling growing device, the seedling growing device absorbs water when the seedlings can be planted, and the seedling growing device itself tends to collapse. Therefore, it may be difficult to move the whole pot seedling when planting this pot seedling.

That is, generally, the seedling stand described above is provided with a ring or belt for feeding pot seedlings in the vertical direction (downward), and as described above, the seedling raising device for pot seedlings is likely to collapse. When sending the whole pot seedling downward, even if the wheel or belt is driven, the bottom of the pot seedling that the wheel or belt contacts will collapse, and only the required amount of seedling will be produced. In some cases, the seedlings could not be delivered, or the seedlings could not be sent to the left and right and the posture of the seedlings was disturbed.

An object of the present invention is to obtain a method for reliably planting the entire pot seedlings and smoothly planting the pot seedlings even when the pot seedlings contain water and easily collapse.

[Means for Solving the Problems]

A feature of the present invention is that a paper-made upper pot material having a large number of upper pot portions protruding upward and a resin lower pot material having a large number of lower pot portions protruding downward are superposed in a plane. When planting a pot seedling obtained by sowing the space formed between the upper pot portion and the lower pot in a field, the pot seedling is planted by the action of the feeding force of the member engaging with the lower pot material. It is located at the point where the pot seedlings are cut out with the planting claws after the lower pot material is peeled downward from the pot seedlings, after being moved to the side of the operating path of the attachment claws, and the action and effect are as follows. Is.

[Work]

According to the above feature, since the pot seedling is composed of an upper pot material made of paper and a lower pot material made of resin, for example, a period elapses until the pot seedling grows into a seedling suitable for planting, and the upper pot material is moistened. Even if it is easily broken by
The lower pot material made of resin will maintain its shape, and when planting pot seedlings, the feed force acts from the member that engages the downward projection of the lower pot material, causing slippage. The required amount of pot seedlings can be sent without doing this, and even when the feeding force acts on part of the lower pot material during this feeding, the pot seedlings are not damaged and the entire pot seedlings can be securely fixed. It will be possible to move to the side of the operating locus. In addition, since the lower pot material is peeled downward after this moving force is applied, the pot seedlings are cut out one by one with the planting claws without hindering the operation of the planting claws by the lower pot materials, and are planted in the field. Can be attached.

〔The invention's effect〕

Therefore, even if the pot seedling contains water and is in a state of being easily collapsed, a method can be obtained in which the entire pot seedling is surely sent by the required amount and planted smoothly.

〔Example〕

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

As shown in FIGS. 2 and 3, a paper-made upper pot member (1) having a large number of upper pot portions (1a) protruding upward.
And a resin-made lower pot material (2) having a large number of lower pot portions (2a) projecting downward are superposed on each other in a plane, and between the upper pot material (1) and the lower pot material (2). The seedlings are sown in the formed space (S), and seedlings are sprouting and grown through the openings (1b) formed in the projecting ends of the upper pot materials (1) to obtain pot seedlings (P). ing.

In this pot seedling (P), the upper pot material (1) is made of a water-soluble paper material, and the lower pot material (2) has a groove shape over the entire width in the lateral direction as shown in FIG. It consists of the formed film material, and when the seedlings (3) are grown, the seedlings (3) are allowed to germinate from the openings (1b) as described above so that the stems and leaves of the seedlings (3) are not entangled with each other. It is designed to be held in a container (4).

When this pot seedling (P) is used for planting, the seedling planting device shown in FIG. 1 is used.

In other words, this seedling planting device is provided 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 power from the chain case (5). An arm (6), a planting arm (9) which is linked to the crank arm (6), and in which the operating locus (T) of the planting claw (8) is set in a loop by the swing link (7), The seedling stand (10) on which the pot seedlings (P) are placed, the sliding rails (11) which slidably support the seedling stand (10) in the lateral direction, and the seedling stand (10) are placed. A vertical feed mechanism (A) for feeding the pot seedling (P) downward, and the lower pot material (2) is peeled from the pot seedling (P) when the pot seedling (P) is moved downward by the vertical feed mechanism (A). Each has a peeling mechanism (B), and the seedling stand (10) is set horizontally when seedlings are planted. While moving, the seedlings (3) are cut out one by one from the bottom edge of the pot seedling (P) and planted in the field (12) (this lateral movement system is not described in detail). When the seedlings (3) are cut out from the entire width of the lower edge of (), the pot seedlings (P) are fed downward by the amount of one plant by the operation of the vertical feeding mechanism (A).

The vertical feed mechanism (A) has endless belts (14) having pit protrusions (14a) which are equal to the pitch at which the lower pot portion (2a) is formed with respect to the upper and lower wheels (13), (13). ), And the peeling mechanism (B) has a curved guide material (1
5), and the lower pot material (2) is formed so as to curve in a natural state as shown by the one-dot chain line in FIG. 2, so that the vertical feeding mechanism (A) feeds the pot seedling (P) downward. At this time, the lower pot material (2) is naturally guided to the guide material (15) side.

Therefore, in this seedling planting apparatus, since the entire pot seedlings are sent downward through the lower pot material (2) at the time of planting seedlings, even if the pot seedlings (P) contain water and are easily collapsed. The seedlings are surely sent without breaking the seedlings, and the seedlings (3) can be planted smoothly.

[Another embodiment]

In addition to the above-described embodiment, the present invention can form a lower pot portion so as to project downward corresponding to each stock with respect to the lower pot material. It is also possible to make a perforation so that the downward peeling can be performed smoothly.Means for peeling the lower pot material is provided by engaging a hook-shaped claw or the like with the lower pot material. It can be implemented in various ways, such as a structure in which forced peeling is performed.
