Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a seedling grower for raising seedlings for use in a transplanter, and more specifically, it is made up of a peripheral wall and a bottom made of a synthetic resin material, and has a plurality of cuts in the bottom. Regarding the seedling nursery.

Conventionally, this type of seedling raising device has a structure in which a cut is simply made in the bottom part so that it can be bent, and after raising the seedlings, the bendable movable bottom plate part is opened to take out the bedded seedlings as they are.

However, in such a conventional seedling raising device, the bending base of the movable bottom plate is not fixed, and therefore, when the movable bottom plate is pushed apart, a generally uniform opening cannot be obtained accurately.

In addition, the bottom of the seedling nursery often bends to the point where it is not necessarily necessary, making it impossible to accurately remove the seedlings from the bed.

This invention aims to eliminate the above-mentioned drawbacks and takes the following technical measures.

That is, the bottom surface 3 of the container is made up of a peripheral wall 2 and a bottom surface 3 formed of a synthetic resin material, and the bottom surface 3 of the container is made up of a peripheral wall 2 and a bottom surface 3 formed of a synthetic resin material. established,
A cut 6 is provided in the section 4 from the center 10 side to the local edge of the section so that the roots of the seedlings can pass through. The structure of the seedling nursery is provided with a movable bottom plate 7 having an elastic force that prevents bed soil from leaking.

An embodiment of the present invention will be described in detail with reference to the drawings. Reference numeral 1 denotes a container for growing seedlings for a rice transplanter, and has a peripheral wall 2 and a bottom surface 3 integrally formed of synthetic resin.

The bottom surface 3 is integrally provided at the lowermost end of the peripheral wall 2 as shown in FIG. 2, or from a slightly upper position as shown in FIG.

4 is a circularly formed partition, as shown in FIGS. 4 and 5.
As shown in the figure, the bottom surface is divided by thin grooves 5,
As shown in FIGS. 3 and 8, a hole 8 is bored in the bottom surface 3, and a separate circular disk 9 of synthetic resin or rubber material is inserted into the hole 8 into a fitting groove 10 on its outer periphery. They are formed and fitted together, and the fitting portions are thickened to form sections.

6 is a cut, which is wide enough to allow the seedling root to pass through;
The partitioning part 4 is oriented in the radial direction from the center within the partitioning part 4.
A plurality of the bottom plates are provided so as to reach the inner periphery of the bottom plate, and this part is constituted by an elastic downward movable bottom plate 7 that bends up and down.

In the upper configuration, bed soil is placed in the container 1, and after sowing, the container is covered with soil, watered, and placed on the field surface to manage seedlings.

During this seeding work, the movable bottom plate 7 provided on the bottom of the seedling raising device has elasticity and does not allow the bed soil to leak out, so the seedling raising device can be freely carried with the bed soil placed in it.

During the raising of seedlings, the water that is irrigated flows down from the cut 6 without accumulating on the bottom surface 3, and the drainage is good and the roots of the seedlings do not rot and grow into the bed soil. The roots that have reached this level penetrate into the soil surface through the cut 6 and absorb nutrients from the soil, allowing the seedlings to grow quickly and large.

Next, to take out the grown seedlings from the seedling nursery, use a pushing rod or the like to push the lower movable bottom plate 7 from the back side of the bottom surface 3. Since this lower movable bottom plate 7 is divided by sections 4, Only the divided portion is pushed upward and the pushing rod is easily inserted, the back side of the seedbed is pushed up and the seedlings with soil can be easily taken out.

As described above, since the present invention is configured as described above, only the divided bottom plate portion can be bent extremely easily and accurately, so that the seedlings grown in the bed can be easily taken out and the bed can be moved. The bottom plate is opened by pushing it open accurately and evenly with a pushing rod, etc., so the seedling bed will not be damaged.Furthermore, since the bottom of the seedling nursery is bent only at the necessary part, the seedling nursery will not be deformed when pushing out the seedlings, and the bed will not be damaged. It has the effect of allowing soiled seedlings to be taken out in an accurate form.
