The long seedling mat seeding machine of the present invention is specifically constructed as shown in FIGS. The seeding machine for the long seedling mat includes a seed hopper 43 and a seed hopper 43.
And a seed dropping port 40 below the seed splashing prevention plate 44. In the embodiment shown in FIGS. 4 and 5, a long seedbed sheet 4 is laid inside the long seedling raising tray 1. Since the nursery sheet 4 is made of a non-woven fabric or the like, unlike the case of the nursery sheet made of conventional soil,
The repulsive force when the seed S falls is large. Therefore, when the seed drop opening 40 and the seedbed sheet 4 are separated from each other, the seed S jumps out of the long seedling raising tray 1 due to the falling speed of the seed S and the repulsive force of the seedbed sheet 4. Of. In order to prevent the seeds S from jumping out, a seed splash prevention plate 44 is extended horizontally from the seed drop opening 40.

In FIG. 4, the seedbed sheet 4 is first laid inside the long-sized seedling raising tray 1 to be conveyed,
Next, a configuration is disclosed in which the seed S is sown by the feeding device K, and finally the seeding sheet 47 is laid on the upper surface of the seed S. The seeding sheet 47 is laid on the seeds S. If the seeds S are sown only on the seedbed sheet 4, the seeds S are lifted by the root development during germination and the roots are formed inside the seedbed sheet 4. This is to solve the problem of not being fully stretched. As in the present invention, by laying the seeding sheet 47 on the seed S, the seed S is pressed against the seedbed sheet 4 with the weight of the seeding sheet 47, and the roots form the seedbed sheet 4.
It should be stretched inside.

By further placing a fertilizer element such as dust or vermilite on the seed sheet 47,
These can be used as weights for pressing the seeding sheet 47, so that the above effect can be further exerted. Further, since the sheet pressing roll 48 presses the seeding sheet 47, the seed S and the seedbed sheet 4 as a whole, the seedbed sheet 4 of the seed S is pressed.
It is also possible to improve the degree of adhesion to.

In the sheet laying mechanism, first, the seedbed sheet 4 is pulled out from the seedbed sheet roll 42 and held by the drive roller 50. The pull-out drive roller 50 can be rotated left and right between the position 50 and the position 50 'in FIG. 4 to change the position. Then, the long seedling raising tray 1 is placed on the conveyor and is forcibly conveyed to the right. Initially, the pull-out drive roller 50 grips the end portion of the nursery sheet 4 at the position 50 on the left side, and rotates from that state to the position 50 'on the right side. In this state, since the nursery sheet 4 is floating above the long seedling raising tray 1, the sheet pressing roll 48 descends from above, and the end portion of the seedbed sheet 4 is placed at the start end of the long seedling raising tray 1. Press.

When the pressed state of the end portion of the nursery sheet 4 by the sheet pressing roll 48 is finished, the long seedling raising tray 1 moves and the seedbed sheet 4 is pulled out onto the long seedling raising tray 1. When reaching the terminal end, the drawer drive roller 50
From the position of 0 ′ to the original position of 50, pivoting over the sheet pressing roll 48 and returning, and again returning to the nursery sheet 4
The side of the nursery sheet roll 42 with respect to the cutter 49 is clamped. In this state, while being stretched between the pull-out driving roller 50 and the sheet pressing roll 48, the cutter 49 is operated to cut the seedbed sheet 4 to a length that matches the length of the long seedling raising tray 1. The pull-out driving roller 50 holds the cut end of the seedbed sheet 4 and waits for the next long seedling raising tray 1 to be conveyed.

Next, the long seedling raising tray 1 reaches below the feeding device K, and the seed S in the seed hopper 43 is fed by the seed feeding roll 41 and seeded on the seedbed sheet 4 from the seed drop opening 40. Further, the long seedling raising tray 1 moves below the seed sheet roller 51 and the seed sheet 47. Since the sheet laying mechanism composed of the pull-out drive roller 50, the cutter 49, and the sheet pressing roll 48 is also provided here, the seeding sheet 47 is laid on the seeded seed S.

A drawing in which the nursery sheet 4, the seed S and the sowing sheet 47 are in a three-layer state is disclosed in FIG. FIG. 4
In the configuration of FIG. 5 and FIG. 5, the seed S is not bonded to the seeding sheet 47, but only the seeding sheet 47 is placed on the upper surface of the seed S. Next, the embodiment of FIGS. 6, 7 and 8 will be described. In this case, the adhesive H is applied on the seeding sheet 47, and the seeding sheet 47 is first laid inside the long seedling raising tray 1 by the device of FIG.
The seed S is dropped from the feeding device K on the surface of the seeding sheet 47 to which the adhesive H is applied.

As a result, as shown in FIG. 7, a sheet of seeds S fixed on the long seeding sheet 47 with the adhesive H is completed. The seed sheet 47 with the seed S does not germinate as it is unless given a certain condition. Therefore, for the time being, the seed sheet 47 is stored in a rolled state as shown in FIG. The seeding is completed by placing the sheet 4 on the long-sized seedling raising tray 1 in a state of being spread. As for the placement state of the seeding sheet 47 with the seed S, the seeding sheet 47 may be on top and the seed S may be on the bottom as shown in FIG. 5, or conversely, the seeding sheet 47 may be on the bottom and the seed S may be on the top. Is also good. In this case, the seeding sheet 47
Also, the root portion when the seed S germinated, such as a non-woven fabric, needs to be made of a material that can bite.

Further, the seeding sheet 47 with the seed S can be placed on the nursery sheet 4 after germinated at high speed under reduced pressure, high temperature and high humidity in another room. In this way, high-speed seedlings can be grown by germinating in a portion different from the long seedling raising tray 1 and then placing it on the long seedling raising tray 1 and the nursery sheet 4. In this case, it is possible to adjust the humidity, the wavelength of the light beam, the humidity, etc. to the optimum one to accelerate the greening and hardening of the seedlings.
