Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bed soil covering material for raising seedlings for raising seedlings of rice, vegetables and the like.

[0002]

2. Description of the Related Art As a conventional technology of this kind,
As disclosed in Japanese Patent Laid-Open No. 58-158111, there is a seedling-raising floor soil covering material composed of a peripheral wall which is inclined upward inward and an upper wall having an elongated hole for leaf stem, which is made of a paper material or the like. Since the surrounding wall and the upper wall of the floor soil covering material are thick enough to maintain a certain strength, if water is sprinkled from above during seedling raising, the water will enter the floor soil covering material from the top of the floor soil covering material. There is a problem that it is difficult to penetrate, and poor germination may occur. Further, even if it germinates, there is a problem that water is difficult to penetrate into the floor soil covering material, resulting in water shortage and the seedlings do not grow smoothly.

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems of the prior art, the present invention is made of a water-absorbing material such as a paper material, and the upper part having elongated holes for leaf stems is thicker than the lower part. Is a thin-walled material for nursery floor soil covering material.

[0004]

[Advantageous effects of the invention] Since it is a seedling-raising soil covering material formed of a water-absorbing material such as a paper material, the upper part having the elongated holes of the leaf stem is formed into a thin-walled part thinner than the lower part, When water is sprinkled in the germination and growth process, water easily permeates into the cover soil and the bed soil from the elongated holes and the thin portion around the extension holes and germinates well. Further, even if germination occurs at a position displaced from the extension hole, the bud can contact the thin-walled portion, push the thin-walled portion laterally to expand, and extend upward from the extension hole. It can be prevented as much as possible.

EXAMPLE In the illustrated example, a nursery bed soil covering material 4 is formed of a paper material having good corrosiveness, and has four peripheral walls 1 ... Inclining upward inward and an upper wall having elongated holes 2 for leaf stems. 3 and the bottom surface is opened. The lower part of the peripheral walls 1 ... Has a thickness of approximately 2 mm, and the upper part of the soil cover material 4 including the upper wall 3 has a thickness of 1 mm.

A plurality of floor soil covering materials 4 are continuously provided, and a connecting wall 6 is provided between the lower edge 5 of the peripheral wall 1 and the lower edge 5 of the peripheral wall 1 of the adjacent floor soil covering material 4. One floor soil covering material sheet 7 is formed by connecting them. Reference numeral 8 is a seedling box, and a bottom plate 9 is provided with a root extension hole 10. Next, the seeding and seedling raising work using the above-mentioned bed soil covering material sheet 7 will be explained. When the seedling raising bed soil covering material sheet 7 is inverted, cover soil is put in from the bottom opening of the seedling raising soil covering material 4 from above, The seeds are sown, the soil is supplied, and then the seedling box 8 placed in the field is inverted and stored again.

Then, the floor soil covering material sheet 7 in the seedling box 8
Sprinkling water from above to sprout and raise seedlings, but each floor soil covering material 4
Since the upper part of each is thinner than the others, this water sprinkling permeates the extension holes 2 and the thin surrounding walls 1 ... To do. Also, when this germinated seedling comes into contact with the upper wall 3, it penetrates through the thin upper wall 3 or pushes the upper wall 3 to the side to form an elongated hole 2
Expand and extend upward.

The roots of the germinated seedlings grow and grow in the field through the elongated holes 10 formed in the bottom plate 9 of the seedling box 8. In the embodiment shown in FIG. 4, the upper peripheral walls 1, 1 of the nursery floor soil covering material 4 are bent inward to form the step A, and the step A
When the upper part of the thin-walled portion is made thin, the nursery floor soil covering material 4 is inverted to cover the soil, sow seeds, and when the soil is supplied and then subdued, the step A portion does not cover much soil in the thin-walled portion. The germination rate can be increased without being strongly suppressed.
