[Structure] The seedling raising pot for transplanters of the present invention is made of an elastic plastic plate provided with a large number of grid-shaped seedling raising rows, and an opening / closing cut piece provided at the bottom of each seedling raising compartment.
The whole or a part of the inner surface of the seedling raising room is formed in an uneven surface shape, a rough surface shape or a grain pattern, and is configured so that there is as wide a space as possible between the root pot part and the inner surface of the seedling raising room. To do.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a pot for a transplanter, which can grow a seedling of a plant seedling, in particular, a pot seedling suitable for rice cultivation in cold regions, which can be directly mounted on the transplanter and planted in a field. It is intended to cultivate rice seedlings for cold regions, which have good rooting, are strong, and have a large yield.

[0002]

[Prior art]

 Traditionally, rice seedlings for cold regions are preferably well-rooted and grow quickly after transplanting, and in the case of mechanical planting, the seedlings must be extruded from the seedling pot with an extrusion rod. It is desirable that the root pot is a hard pot seedling. A seedling raising pot for growing such excellent seedlings and suitable for mechanical planting is proposed in Japanese Patent Publication No. 56-34347.

In this kind of pot, a large number of pot-shaped seedling chambers each having an openable / closable cut piece on the bottom surface are arranged in a grid pattern, and support portions for suppressing the upper edge are attached to both right and left sides of the pot at the same time. It itself is a kind of seedling frame or seedling box shape that is freely curved so that it is suitable for mechanical planting.

[0004]

[Issues to be solved by the device]

 The seedlings for transplantation having such a structure could achieve the intended purpose for mechanical planting, but there was still plenty of room for improvement for cold climates. For example, there are issues such as further reduction of leaf withering in cold paddy fields, improvement of eating quality, and improvement of high-level stability of yield due to improvement of rooting and early growth.

[0005]

[Means for Solving the Problems]

 In order to improve these issues, the biggest problem is to improve the rooting and wrapping in the seedling raising pot. Therefore, in the present invention, the inner surface of the seedling raising pot is formed with an irregular rough surface, an uneven surface or a grained surface so as to widen the contact surface with the seedling root to promote rooting and root winding, and at the same time to grow the soil and the pot. We succeeded in growing high quality adult seedlings by enlarging the surface area between inner surfaces and increasing the supply rates of oxygen and fertilizer, promoting the growth of seedling roots and leaves.

[0006]

[Function of the invention]

 Thus, the seedling-growing pot of the present invention increases the root tension of rice seedlings, enhances the root wrapping, and grows pot seedlings with a harder root pot. It has the effect of improving the initial growth. Furthermore, since the rooting and oxygen supply were sufficient, we succeeded in growing high yielding seedlings with many seedling leaves, better initial growth, quick heading, good temperature control and high yield. An embodiment of the present invention will be described below with reference to the drawings.

[0007]

【Example】

 The seedling raising pot (4) for a transplanter of the present invention comprises a large number of grid-shaped seedling raising chamber rows (8) (8). . Made of frame-shaped elastic plastic with holes, and sprocket holes (7) (7). . . As shown in FIG. 1, it is mounted on the seedling raising pot supply guide plate (3) of the adult seedling transplanting machine (1), and the extruding bar (5) of the transplanting machine (1) allows the wheels of the transplanting machine (2). ) In the direction (F), the root pot (6) is moved to the nursery room (8) (8). . It is configured to be extruded from above into a field (W) or mechanically planted by a planting device (not shown).

On the other hand, the cross-shaped seedling raising room (8) (8). . . As shown in FIGS. 3 and 4, the cut-out pieces (10) (10) for pushing out the adult seedlings are provided on the bottom surface thereof. . At the same time that the surface is cut, a fine concavo-convex surface (13) (see Fig. 5) or a rough surface (11) is provided. 9) was created and it is considered to expand the contact surface between the soil in the nursery room (8) and the surface of the nursery room as much as possible.

Thus, in the nursery room (8), the space between the soil (14) and the nursery room (8) is remarkably increased as compared with the bare room, and air entering or staying through this space is Sufficient oxygen is sent to the roots of the seedlings, and the roots (12) of the adult seedlings are made thick and run vertically and horizontally in the soil to firmly form the root pots (6), and at the same time the pots are separated from each other at the time of transplantation. A well-grown seedling root can increase the number of leaves of the seedling (15) to accelerate heading and increase the temperature rise to increase the yield.

[0010]

[Effect of device]

 According to the seedling raising pot for transplanter of the present invention, the contact surface with the rice seedling root is expanded by simply making the whole or a part of the inner surface of the seedling raising room a rough surface or a grained surface, according to the above-described structure and operation. As described above, it is possible to cultivate excellent rice seedlings suitable for mechanical transplantation at low temperature by improving air circulation to help root hair growth, strengthening and enlarging root wrapping and rooting. I have it.

[Scope of utility model registration request] 1. Along with the provision of a large number of grid-shaped nursery room rows, a cut piece that can be opened and closed is provided at the bottom of each nursery room so that the grown seedlings grown in the nursery room can be used as a desired transplanter. After being mounted, in a seedling raising pot for a transplanting machine formed so as to be mechanically transplanted on a field by sequentially pushing out with a pushing rod capable of penetrating the cut piece, the inner surface of each seedling raising room has a fine uneven surface or Seedlings for transplanters, characterized by being formed into a rough surface so that the contact surface between the soil inside the nursery room and the inside of the nursery room is expanded as much as possible to improve root winding and rooting of the seedlings. pot.
