Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nursery box for raising seedlings such as paddy rice.

[0002]

2. Description of the Related Art Conventionally, there is a nursery box for raising seedlings such as paddy rice, which is provided with a drainage hole on the bottom surface. In this seedling raising box, the roots of the seedlings extending downward project from the drainage holes provided on the bottom surface of the seedling raising box to the outside of the seedling raising box. Thereby, the roots of the seedlings may extend into the soil of the bed where the nursery box is placed, and the roots of the seedlings that have grown in the soil of the bed may absorb nutrients in the soil of the bed, Raised seedlings may have uneven growth. Further, when the seedling box is moved, if the roots of the seedlings extending outside the seedling box are biting on the bed, it may be difficult to remove the seedling box.

To solve the above problem, there is a nursery box in which drain holes are provided on the side walls of the nursery box. However, in this nursery box, it is difficult to make the bottom surface of the nursery box completely horizontal. Therefore, it is difficult to drain the water smoothly, so that water easily accumulates at the bottom of the nursery box, and uneven growth of the seedling is likely to occur depending on the position in the nursery box.

[0004]

The present invention takes the following technical means to solve the above-mentioned problems. That is, a seedling raising box 1 for raising seedlings provided with drain holes 5 on the side walls 2, 2.
In the above, a seedling raising box having an inclined portion provided on the bottom plate 4 so as to descend toward the drain holes 5.

[0005]

In the nursery box of the present invention, the seedling raising box is filled with a floor material such as cultivated soil and sowed to grow seedlings. In this seedling raising, when the seedling box is irrigated, the floor material such as cultivation soil absorbs water and seeds are absorbed from the floor material to grow a seedling. Excessive water that is not held by the material and falls to the bottom of the seedling raising box flows through the inclined portion of the bottom plate of the seedling raising box toward the drain hole in the side wall, and is drained from the drain hole.

[0006]

According to the nursery box of the present invention, the roots of the seedlings are prevented from growing into the soil of the bed on which the nursery box is placed, so that the nursery box in which the seedlings have been raised is difficult to remove. Excessive water that has fallen to the bottom of the seedling box without being held by the flooring is drained from the drainage hole on the side wall through the slope of the bottom plate of the seedling box. It can be efficiently discharged from the inside of the box, and it is possible to prevent uneven growth due to water scattering at the bottom of the seedling box.

[0007]

An embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a nursery box 1 for cultivating a mat-shaped paddy rice seedling. The nursery box 1 has a rectangular mat seedling of about 60 cm in the longitudinal direction and about 30 cm in the lateral direction, so that the seedling can be raised. Four side walls 2, 2, 3, 3 and a bottom plate 4 are provided and the upper part is opened. The four side walls 2, 2, 3, and 3 have a height of 2 mm from the upper surface of the shingle plate.
It is provided to be 9 to 30 mm. Side wall 2,2 provided in the longitudinal direction among the side walls 2,2,3,3
In the lower part of the plant, drainage holes 5 having a height of about 2 mm are provided at equal intervals, and the seedling raising box 1 has a configuration in which a total of six drainage holes 5 are provided. The bottom plate 4 is a nursery box 1
With the central portion 6 in the short side direction of the upper side positioned higher,
, And forms an inclined portion that descends toward the drain holes 5. The central portion 6 being a high position and the both end portions 7 being a low position,
7 is provided so as to have a height difference of 1 mm to 1.5 mm. A grain (shallow groove) 8 is provided along the inclination direction of the inclined surface, and water that has dropped down to the bottom plate 4 by the grain 8 from the central part 6 of the seedling raising box 1 to both end parts 7, 7 so as to easily flow along the inclined surface. A plurality of ribs 9 are provided below the bottom plate 4, and the ribs 9 prevent the bottom plate 4 and thus the seedling raising box 1 from bending.

Next, the seedling raising process of the rice seedling by the seedling raising box 1 will be described. First, the seedling raising box 1 is filled with a predetermined amount of seedling cultivation soil. Then, seeds are scattered and sowed on the filled seedling cultivation soil, and a predetermined amount of seedling cultivation soil is covered. Then, the seedlings are irrigated by sprinkling water from above the seedling raising box 1 to grow the seedlings, and the roots and buds elongate from the seed rice. The growing roots absorb nutrients in the seedling cultivation soil and absorb water from the seedling cultivation soil that has been absorbed by irrigation, so that the seedlings grow.

Therefore, the water that is not held by the seedling raising soil and falls to the bottom of the seedling raising box 1 is drained from the drain holes 5 of the side walls 2 and 2 through the inclined surface of the bottom plate 4 of the seedling raising box 1. Excessive water that has fallen to the bottom of the box 1 can be efficiently discharged from the seedling box, and uneven growth due to water scattered at the bottom of the box 1 can be prevented. That is, it is possible to prevent the mat seedlings from growing irregularly.

[0010] The roots extended from the seed paddy are the side walls 2, 2
Of the nursery box 1 from the drain holes 5
The extension of the roots to the bed of the nursery box 1 is suppressed, and the extension of the roots to the bed of the nursery box 1 makes it difficult to remove the seedling box 1 from the bed. In addition, since the seedling raising box 1 is not provided with a drainage hole in the lateral side walls 3 and 3 of the seedling raising box 1 and the root does not protrude outside the seedling raising box 1 on the side walls 3 and 3, When the mat is seeded from the seedling raising box 1 by inserting the mat from the side walls 3 and 3 in the short direction to the bottom of the seedling, the end of the mat seedling can be easily lifted and the seedling collecting plate can be inserted.

The bottom plate 4 of the seedling raising box 1 is not provided with a hole communicating with the outside of the seedling raising box 1.
May be provided with a small hole that does not allow water to pass through. The bottom plate 4 may be provided with an inclined portion having an inclined surface such that only a part of the bottom plate 4 descends toward the drain holes 5.

By the way, as shown in FIG. 4, drainage grooves 10, 10 having the same height as the lower surface of the drainage holes 5 are provided in both side portions 7, 7 of the seedling raising box 1 in the longitudinal direction. Is also good. The drain grooves 10, 10 are provided at a position lower than the lower end of the inclined surface of the bottom plate 4, accumulate water flowing to the both sides 7, 7 along the inclined surface, and promote drainage from the drain holes 5. can do.

Further, as shown in FIG. 5, the bottom plate 4 may be an inclined surface such that the diagonal line of the seedling raising box 1 is at a high position. Since the bottom plate 4 of the nursery box 1 is inclined so as to descend toward the outer peripheral portion of the nursery box, water is easily supplied to the outer peripheral portion of the nursery bed that is easy to dry, and uneven growth is suppressed. It has a configuration.
