DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail with reference to the drawings. 1 is a seedling raising material, as shown in FIG. 4 and FIG.
Each of a large number of pot-shaped accommodating portions 2 including a wall portion 2d and a bottom portion 2b having a hole 2c formed therein is independent from each other on the bottom portion 2b side and connected to each other vertically and horizontally on the opening portion 2a side. , Are arranged in a square shape and are connected to each other. The overall size is 280 mm in width and 290 m in height.
m, vertical height 20 to 25 mm, general nursery box 3 (inside dimension: (horizontal) 280 mm × (vertical) 580 mm × (deep) 3
The size is such that two seedling raising materials 1 can be placed side by side in 0 mm).

Each pot-shaped accommodating portion 2 of the seedling raising material 1 has 4
.. and bottoms 2b having holes 2c. The openings 2a .. and the bottoms 2b have a quadrangular plan view shape and a truncated pyramid shape with a trapezoidal side view. The opening 2a has a size of 25 mm in length and width and is a quadrangle close to a square. Since the bottom portions 2b are independent of each other, they are smaller than the openings 2a, and have a rectangular shape with a size of about 20 mm in length and width, and one round hole 2c having a diameter of 15 mm is formed. The depth from the upper end surface of the opening 2a to the bottom 2b is 28 mm. It should be noted that the pot-shaped accommodating portion 2 ...
May have a truncated cone shape, and the bottom portion 2b may have a circular or hemispherical curved surface shape. Also, hole 2
c may be a square hole, or the pot-shaped accommodating portion 2 having a cylindrical shape without the bottom portions 2b.

The seedling raising material 1 is molded as follows. That is, used waste paper made only of newspaper without magazines and advertising leaflets mixed, dissolved in water to make a waste paper solution, and immersing the outside surface side of the wire mesh formwork in the used paper solution to form a predetermined form on the formwork. Adhere to thickness. Then, after removing the water, the attached waste paper is removed from the form and dried to mold the seedling raising material 1 having a predetermined shape. The wire netting form has the same shape as the inner surface shape of the seedling raising material 1, and projections are integrally provided downward at portions corresponding to the bottom portions 2b of the pot-shaped storage portions 2 ... Also, the solution does not adhere to the protrusions, so that the holes 2c of the bottom portion 2b of the pot-shaped accommodating portion 2 are formed.
... is molded. As described above, since the seedling raising material 1 is made of paper, seedlings can be transplanted together to the field without being separated from the seedling raising material 1, and the seedling raising material 1 will be corroded in the soil of the field after transplantation. The seedling raising material 1 may be made of biodegradable plastic instead of paper, that is, a material that corrodes in the soil may be used.

Now, the seedling raising material 1 constructed as above ...
Is used to raise seedlings of vegetables as described below, and the seedlings are transplanted to a field for cultivation. That is, the seedling raising material 1 is accommodated in the seedling raising box 3 with the openings 2a ... The soil 4 is sufficiently filled while being pushed into the pot-shaped storage portions 2 ... through the holes 2c. When each pot-shaped accommodating portion 2 is completely filled with the soil 4, the seeds S of vegetables such as lettuce and cabbage are sowed in the center of the hole 2c. Then, again, the soil 4 is added to fill up the seedling raising box 3 up to near the upper end (FIG. 1). After making the nursery in this way, raise the seedlings by appropriate watering and temperature control. Then, the root R1 extends downward from the seed S, and the stem K extends upward. The root R1 extending downward extends further while forming a root pot in the floor B1 on the lower side of the floor, that is, the floor inside the pot-shaped housing 2. The stalk K extending upward goes out of the soil and leaves H are attached. The root R2 is a root that extends in the plane direction from the part in the soil in the stem K that extends upward, and the root R2 is a floor upper part B2, that is, a floor part above the pot-shaped accommodating part 2 ... Roots and grows (Fig. 2). The thus-grown vegetable seedlings are separated into individual plants at appropriate times, that is, separated into each pot-shaped container 2, and transplanted to the field (FIG. 3). As for the seedlings transplanted to the field, the roots R2 grow smoothly without being hindered by the pot-shaped housing portions 2 ... In this case, since the upper side of each pot-shaped accommodating portion 2 is independent, the seedlings of the transplanting machine are invaded into the valleys between the pot-shaped accommodating portions 2 ... It is easy to separate each plant and is suitable for seedlings supplied to transplantation machines.

In the above, the opening 2a in the nursery box 3 ...
The seedling-growing material 1 is housed and used so that it is on the lower side, but conversely, the seedling-raising material 1 is housed in the seedling-raising box 3 so that the openings 2a ... May be.
In this case, when the soil 4 is filled to the upper end of the opening 2a of each pot-shaped housing 2, the seeds S are sown one by one in the center of the opening 2a, and the soil 4 is again placed on the seed S. Nursery box 3
Fill up to near the top. When a nursery bed is formed and seedlings are raised in this way, the root R1 extending downward from the seed S further extends while forming a root pot in the floor lower side B1, that is, the floor inside the pot-shaped accommodating portion 2. The stalk K extending upward goes out of the soil and leaves H are attached. The root R2 of root grows and grows on the floor B2 above, that is, the floor above the pot-shaped housing 2. The thus-grown vegetable seedlings are separated into individual plants at appropriate times, that is, separated into each pot-shaped storage unit 2, and transplanted to the field. As for the seedlings transplanted to the field, the roots R2 grow smoothly without being hindered by the pot-shaped accommodating portions 2 ... Therefore, the rooting to the field proceeds smoothly and good cultivation can be performed.

As described above, this vegetable seedling is covered with a material that corrodes the bottom side surface of the floor part in the soil when it is separated into one plant, and the side surface on the upper side of the floor part and the bottom surface of the top surface of the floor part expose the floor soil. The vegetable seedlings were in the state of being allowed to grow, and the sprouting roots were extended on the upper side of the floor where the side surfaces were not covered to raise the seedlings. Therefore, when this seedling is transplanted to the field, the gall roots effective for rooting grow smoothly, the rooting to the field progresses smoothly, and good cultivation is possible.

By the way, FIGS. 6A and 6B show the structure of a multi-film. That is, the mulch film 10 includes sheet portions S1 and S1 made of paper and sheet portions S2 and S2 made of biodegradable plastic sheet.
Consists of S2 and S2, and when laid on a ridge,
Sheet part S1 made of paper for the part that touches the upper surface of the ridge
S1 is located, and sheet portions S2, S2, S2 made of a biodegradable plastic sheet are located between the ridges covered with soil for stopping the mulch film. As a result, the sheet sheet portions S1 and S1 on the upper surface of the ridge
Is very fragile by ultraviolet rays. Further, the sheet portions S2, S2, S2 of the biodegradable plastic sheet between the furrows covered with soil are decomposed by microorganisms in the soil. The biodegradable plastic sheet is not easily decomposed when exposed to the soil surface, and is easily decomposed in the soil. After the crop is harvested, this mulch film is considerably deteriorated and decomposed, so that it only needs to be scraped into the field, eliminating the conventional stripping operation and burning the stripped film.

7 (a) and 7 (b) show the structure of the soil bag for vegetable cultivation. That is, this paddy bag 20
Is formed in a bag shape by vinyl sheet such as vinyl chloride, and a small bag 20a is fixed to the inner surface side of the bag. A small hole 2 at the bottom of the small bag 20a
0b ... is open multiple times. The use of this paddy bag 20 has the following advantages. That is, for long-term storage and transport efficiency, a large amount of organic matter and a considerably dried state of the soil is packed in the soil bag 20 and sealed. When the bag-filled soil is used, it is opened the day before it is used and the small bag 20a inside the bag is filled with a preset amount of water to stand up. Then,
On the day of use, the water will be sufficiently hydrated, and even if the seeding machine is used for continuous seeding, it is possible to achieve a uniform watering state by irrigation with the seeder, and uniform germination is possible. still,
When using the dry soil, if the seeding work is continuously performed using the seeder, the watering by the seeder does not sufficiently absorb water in each seedling box, resulting in a non-uniform watering state, There were situations where uniform germination was not possible.
