As shown in FIG. 1 and FIG.
The _1, defining between sheet pieces 17 ₁ adjacent to each other, the shielding member 23 is inserted consisting of paper or the like. Each of these shielding members 23 is a sheet piece 17 ₁ , 17
_It functions to prevent the roots of the seedlings raised in step ₁ from extending across the slit 181. Instead of using the shielding member 23, along the longitudinal direction of the laminated sheet 13 ₁ slit
18 may be stopped by inserting the shielding member 23 is relatively large _first width and the sheet piece 17 ₁ facing the slits 18 ₁
It is also conceivable to eliminate continuous pores from the side surface. In this way, it is possible to prevent the roots of seedlings grown in the sheet piece 17 ₁ from entering the sheet piece 17 ₁ adjacent seedlings with the sheet piece
17 ₁ It is possible to simplify the rooting.

[0040] The preparation of such seedling raising sheet 11 ₁ is carried out in the following manner. First, a long block made of a porous material having continuous pores was formed. Subsequently, to form a porous sheet 14 ₁ by slicing this block into a thickness of 3 to 10 mm. Next, the reinforcing sheet to the porous sheet 14 ₁ consisting of said porous sheet 14 ₁ and the same shape of the nonwoven fabric
To form a laminated sheet 13 ₁ by bonding a 15 _1. Next, after bonding the laminated sheet 13 ₁ to the support 12 ₁ performs punching the laminated sheet 13 _1, the housing recess 16 _1, slit
18 _1, holes 20 ₁ and with a gimmick hole 21 ₁ formed in the laminated sheet 13 _1, two upper and lower rows of holes 19 _1, 19 ₁ and notches 22
To form a ₁ to the support 12 _1.

When, for example, a flexible polyurethane foam is selected as the porous material having continuous pores, polyols such as polyether polyols and polyester polyols, tolylene diisocyanate, 4,4 '
Mixing an organic isocyanate such as diphenylmethane diisocyanate, an amine catalyst such as triethylenediamine, a tin catalyst such as dibutyltin dilaurate, a foam stabilizer such as silicone oil, and a foaming agent such as H ₂ O and a low boiling solvent, After stirring and foaming, the crosslinking is completed to obtain a polyurethane foam. However, a coloring agent, a filler, a fertilizer, and the like may be added as needed.

By the way, in the which is one polyols material in the production of flexible polyurethane foams, there is a polyether polyol and a polyester polyol as described above, the porous sheet 14 used in the nursery sheet 11 _1
In order to obtain ₁ , it is desirable to use a polyether polyol. This is because in the case of using polyether polyol, the number of independent pores is large, the air permeability is small, and the hydrolyzability is larger than that in the case of using polyether.

Further, the density of the flexible polyurethane foam may be a commonly available density of 14 to 15 kg / m ³ , but if the density is less than 16 kg / m ³ ,
May become broken when multiplied by the intensity claw hooking bore 21 ₁ in the implanted nail 65 during (especially tensile strength and tear strength) transplantation is reduced (see FIGS. 11 to 13), also density 35Kg
If / m ³ is exceeded, the pore diameter becomes too small and germination and seedling growth may be hindered depending on the type of seedling.
It is desirable that the density of the polyurethane foam is 16 to 35 kg / m ³ .

Here, in an actual production example of a flexible polyurethane foam, the molecular weight is 3000, the number of functional groups is 3, and the OH value is 5
6, 100 parts by weight of polyether polyol, 0.01 parts by weight of triethylenediamine (amine catalyst), 0.15 parts by weight of normal ethyl morpholine, 0.12 parts by weight of dibutyltin dilaurate (tin catalyst), and 5 parts of water. 0.5 parts by weight, 1.2 parts by weight of silicone oil (foam stabilizer), and tolylene diisocyanate (2.4 / 2.6 = 80/20)
By mixing, stirring and foaming 67 parts by weight,
A flexible polyurethane foam was obtained. The physical properties of the obtained flexible polyurethane foam are as follows:
m ³ , tensile strength 1.1 kg / cm ² , tear strength 0.6
It was 2 kg / cm and the elongation was 160%.

When, for example, a nonwoven fabric is selected as the porous material having continuous pores instead of the flexible polyurethane foam, long fibers and short fibers such as polypropylene fibers and polyethylene fibers are continuously spun and entangled.
What is necessary is just to continuously shape | mold to predetermined thickness.

The block obtained from the porous material having continuous pores in this manner is 3 to 1 by a slicer.
Are those formed as the porous sheet 14 ₁ by slicing to 0mm thickness, in the present embodiment 1 4.5 mm
Thick slices were used.

[0047] When adhering to each other a support 12 ₁ and the laminated sheet 13 _1, for example, support 12 ₁ is a film of polyethylene terephthalate, porous sheet 14 ₁ is flexible polyurethane foam which is one configuration of the laminated sheet 13 ₁ from it, and when the reinforcing sheet 15 ₁ is one configuration of the laminated sheet 13 ₁ is made of non-woven fabric, instead of bonding the entire surface of the opposing surfaces of the support 12 ₁ and the laminated sheet 13 _1, of the opposing surface It is desirable for the parts to adhere to each other.

[0048] By performing such partial bonding, thereby increasing the tensile strength of the laminated sheet 13 ₁ than off force of the laminated sheet 13 ₁ by implantation pawl 65 (see FIGS. 11 to 13), supporting the laminated sheet 13 ₁ it is possible to reduce the force required to allowed to peel from the body 12 _1. When the laminated sheet 13 ₁ is separated from the support 12 ₁ , the support 12
It is possible to reduce the tensile strength acting on the _1, the support 12 ₁ can be made relatively small set the tensile strength is required.

[0049] In the punching by mold support 12 ₁ and the laminated sheet 13 _1, sequentially executing the two steps of the entire cutting and half-cutting. First, in the entire cutting process, a laminated material formed by laminating the support 12 ₁ and the laminated sheet 13 ₁ is arranged so that the laminated sheet 13 ₁ is located at an upper position, and the laminated material is completely punched out so that a blade mold is formed. holes 19 ₁ sends a member, to form a claw hooking bore 21 ₁ and the semi-circular cut chipping unit 22 _1. Next, in the half-cutting step, only the laminated sheet 13 ₁ is punched out without cutting the support body 12 ₁ with another blade-type member by another blade-type member, so that the storage recess 16 ₁
And forming the slit 18 _1. By ending the series of manufacturing steps in this way, to produce a seedling sheet 11 _1.

[0050] In performing the nursery seedling by seedling sheet 11 ₁ manufactured as described above are those hydroponic culture is employed, for example, when the seedlings of rice, to the housing recess 16 ₁ nursery sheet 11 ₁ Each seed rice after sowing is stored. Incidentally, nursery conventional rice is it has to carry out immersion species and germination process had been to perform seeding, the seedlings with seedling sheet 11 of _the present invention also be preceded any seed soaking and seed Good. For example, when immersion is performed before sowing, the seed rice is stored at a relatively low temperature of about 15 ° C. or less, and the seed rice after sowing is stored in each of the storage recesses 16 _1.
Housed in, then, nursery sheet 11 _1, as shown in FIG. 6
Is wound in a roll to perform a soaking treatment. In this case, the laminated sheet 13 ₁ is previously wound nursery sheet 11 ₁ so as to be disposed on the outer peripheral side, 10-15 days seedling sheet 11 ₁ remains rolled around 10 ° C. at a low temperature Soak in water to perform the seeding treatment.

In performing the germination treatment after the seeding treatment, a seedling raising apparatus shown in FIG. 7 is used. Numeral 31 in the figure is a nursery house, and a nursery room 33 in the nursery house 31 is provided with a nursery tank 33. This is the bottom of the seedling raising tank 33 is mounting shelf 34 is positioned, seedling sheet 11 ₁ wound into a roll on the placing shelf 34 is placed. Before wherein shelf 34, it is desirable that the roots extending from the seedling sheet 11 ₁ downward is formed in a lattice shape in order not entangled with one another.
A circulation pump 35 and a heater 36 are sequentially connected to the nursery tank 33 to form a water circulation system 37. A spray shower device 38 branched from a water circulation system 37 between the heater 36 and the nursery tank 33
There are disposed so as to be sprayed from above the seedling sheet 11 ₁ in the mounting shelf 34.

[0052] Seed In nursery by such seedling raising equipment, each housing recess 16 ₁ nursery sheet 11 _1, as shown in FIG. 8 (A), after seeding with the endosperm 39b which and the embryo 39a upward downward 39 leave housed, is placed on the shelf 34 placing the seedling sheet 11 ₁ wound into a roll. In this manner, the posture of the seed paddy 39 is regulated by the arrangement of the germ 39c of the embryo 39a on the top or side and the radicle 39d on the bottom or side, thereby improving the germination rate and the height of the seedling. This is because they are easy to align.

Until germination, 32
The hydroponic solution heated to about 35 ° C. is circulated in the water circulation system 37, and the hydroponic solution is sprayed from the spray shower device 38 every 5 to 8 hours, for example. At this time, the nursery sheet 11 ₁ in the nursery tank 33
There If left immersed in hydroponic solution, since germination by oxygen deficiency is inhibited, the hydroponic liquid level in the nursery tank 33 may be set to L _1, as shown in Figure 7, seedling sheet 11 ₁ to 30
Keep in the air at 32 ° C. Since light is not required until germination, the seedling raising house 31 is subjected to light-shielding treatment.

In the seedling raising process, as shown in FIG. 8 (B), the pod 39e grows upward from the seed paddy 39, and the seed root 39f extends downward from the seed paddy 39.

[0055] The post-emergence, since it is possible incorporate the oxygen by respiration of leaves, it is possible to submerge the seedling sheet 11 ₁ in the hydroponic liquid level L ₂ corresponding to the bottom of the seedling sheet 11 ₁ If, sets the hydroponic liquid level in the nursery tank 33 between the level L ₃ which corresponds to the upper end of the seedling sheet 11 _1. Thus, in the case where than the level L ₃ have set the hydroponic liquid level downward, supplying a hydroponic solution hydroponic solution to the seeds 39 sucked up by the capillary phenomenon of the porous sheet 14 ₁ in the seedling sheet 11 ₁ It is possible to spray water by the spray shower device 38 if necessary. In addition, since light is required after germination, the shading treatment of the nursery house 31 is released.

After germination from all the seeds is completed,
The temperature in the seedling raising house 31 is gradually lowered so as to be about 20 ° C. at the end of the seedling raising, and the humidity is also gradually lowered so as to be exposed to the wind. In this way, the seedlings can be prevented from growing, and can be grown strong. Then, with the seedling after germination,
As shown in FIG. 8 (C), the first leaf 39 due to photosynthesis and the like.
g and the second leaf 39h to about the sixth leaf (not shown) grow, the seed root 39f further extends, and a crown root 39i grows from the root of the seed root 39f.

At the time of such seedling raising, about the hydroponic solution,
It is desirable to automatically manage the temperature, EC (electric conductivity), pH (hydrogen ion index), etc.
Since H changes easily, it is desirable to constantly manage it while circulating the hydroponic solution.

After the germination is completed, the seedling raising sheet 111 is floated from the mounting shelf 34 _one to three days before the rice planting,
11 Insert the seed root 39f extending downward from ₁ into a seedling raising sheet, for example.
11 The cutting is performed by a cutter that travels between ₁ and the mounting shelf 34. Thus, when the thick roots emerge from the seed rice 39 after a lapse of 1 to 3 days after the cutting of the seed root 39f, good rooting can be obtained by performing rice planting.

The purpose of soaking the seed paddy 39 is to dissolve in the water a substance contained in the epidermis of the seed pad 39 that suppresses germination in addition to the water supply, and to remove the sprout inhibiting substance efficiently. In order to dissolve in water, appropriate temperature and humidity maintenance and sufficient oxygen supply are required. The temperature during the period from germination to germination is optimally 30 to 32 ° C., and germination is the fastest in such a temperature range, and germination is the best. At low temperatures below 30 ° C, it is easy to get sick, and at high temperatures above 32 ° C, respiration becomes too active, the consumption of endosperm 39b becomes faster, and the seedling length is abnormally prolonged and it is easy to produce incense seedlings. Have been done.

[0060] Thus, the seedling with seedling raising equipment using the seedling sheet 11 ₁ as described above, it is possible to make not to both water shortage and oxygen shortage that inhibits the growth of rice seeds 39 occurs, germination The inhibitor can be dissolved and removed in a hydroponic solution to promote uniform germination and germination.

Here, the results of comparison of the germination rate between the seedling raising method according to the present invention and the seedling raising method according to the prior art are shown in FIG. 9. To achieve even germination and emergence, and subsequent growth can be excellent.

[0062] Further, seedling sheet 11 ₁ at seedling is wound into a roll has been compactly as shown in Figure 6, allows seedling numerous seeds in nursery sheet 11 ₁ in its compact shape Therefore, the space required for raising seedlings can be reduced, and as shown in FIG.
Compared with those of the prior art, it is possible to greatly reduce the seedling raising area.
