  Next, a method in which the burdock seeding and molding machine 1 according to the present embodiment seeds the field will be described.

[Point a in FIG. 1]
In the burdock seeding and molding machine 1 according to the present embodiment, seeds are enclosed while being pulled by a traveling unit in a field in which the soil at the center of the strip to be sown is dug up and a groove T is formed in advance, and the soil is backfilled in the groove T. The seed tape 2 is sown by laying along the groove T. That is, as shown in FIG. 4A, a trench T having a depth suitable for growth of burdock G is formed by digging up soil in the field by a trenching device such as a trencher. Prepare the seeds to be sown in advance by backfilling the soil. 1 is a non-cultivated soil S0, which is not cultivated soil, and a trench T is formed, and the soil dug up (returned soil S1) or brought in from another place. Is filled in the groove T. Here, the return soil S1 is softer because the gap is larger than the non-cultivated soil S0.

[Point b in FIG. 1]
The operator operates the tractor, which is the traveling unit, with the return soil S1 that is the center of the left and right of the strip as a travel target, so that the pressure suppression guide wheel 41 is fitted in the groove T, that is, the pressure suppression guide wheel 41 is guided in the groove T. Drive in the state. Therefore, at the point of arrow b in FIG. 1, as shown in FIG. 4B, the non-cultivated non-cultivated soil S0 on the left and right sides of the groove T is harder than the cultivated return soil S1. The pressure reducing guide wheel 41 is guided by one or both of the left and right side portions of the groove T, and the left and right positions thereof pass through the upper portion of the groove T. Therefore, the return soil S <b> 1 above and above the groove T is suppressed by the suppression guide wheel 41. Then, the suppression part S2 which is the part by which the return soil S1 was suppressed is formed. Here, since the pressure suppression part S2 is suppressed by the pressure suppression guide ring 41, it is smaller and harder than the soil grain gap of the surrounding return soil S1.

[Point c in FIG. 1]
After that, the non-cultivated soil S0 on the left and right outer sides of the groove T was cultivated by the outer claws 32b and 32b by the nail claws 32a. The soil (hereinafter simply referred to as tilled soil S3) is moved toward the groove T side (left and right center portion of the aircraft). Then, as shown in FIG. 4 (c), the cultivated soil S3 is covered above the pressure reducing portion S2, and two gentle mountains are formed by the cultivated soil S3.

[Point d in FIG. 1]
Furthermore, as the burdock seeding and forming machine 1 proceeds while working, the left and right sides of the rotary cover 33 of the tilling device 30 come into contact with the tilled soil S3, but the center part does not come into contact with the tilled soil S3. Of these, the outer sides of the left and right sides are pushed further toward the center of the machine body (the groove T side). After that, the seed tape 2 is laid on the upper surface of the cultivated soil S3 above the groove T from the lower end of the guide nozzle 62 disposed between the cultivator 30 and the culvert former 50. At this time, since the pressure reducing guide wheel 41 provided in the front part of the burdock seeding and molding machine 1 is in the state of being guided by the groove T, the seed tape 2 is laid above the groove T without detaching from the strip. be able to. Furthermore, since the tilling device 30 is a center drive type, the non-cultivated soil S0 on the left and right upper portions of the groove T can be left as hard soil without tilling.

[Point e in FIG. 1]
Further, a cocoon is formed by leveling the cultivated soil S3 cultivated by the cultivator 30 with the side sheets 56 and 56 and the flat plate 57 by the culverter 50 behind the cultivator 30. At this time, the upper part of the basket is leveled by the leveling plate 57, so that the soil above the seed tape 2 is covered in a uniform state. Moreover, as for the cultivation soil S3 covered above the seed tape 2, the depth of the covering soil can be adjusted by the operator operating the adjustment unit of the cage forming device 50 in advance.

  The seed (burdock G) sown in the field through such a stage is easy to germinate and root since the seed tape 2 is surrounded by the soft soil S3. Further, as the growth of burdock G progresses, as shown in FIG. 5 (a), the root is extended downward and reaches the suppression part S2.

  Here, the pressure reducing portion S2 is a hard portion having a smaller gap than the surrounding return soil S1, and therefore the water flowing into the basement in the return soil S1 can be retained as capillary water due to the small clearance. . That is, the pressure reducing part S2 can hold more water that the burdock G can absorb than the return soil S1. In other words, the pressure suppressing part S2 has higher water retention than the return soil S1.

  In addition, if only the cultivated soil S3 and the return soil S1 are in the state without forming the pressure reducing portion S2, when the load is applied to the leaves by wind or the like, the soil around the root is soft and falls down without being supported. . However, since the suppression part S2 is harder than the surrounding return soil S1 and tilling soil S3, it can prevent the fall after burdock G germination. That is, the pressure reducing portion S2 is softer than the non-cultivated soil S0 and harder than the return soil S1 and the cultivated soil S3, so that the root is straight in the groove T along the groove T shown in FIG. While extending, it is possible to prevent the burdock G from tipping over after germination, as compared with the case where the root is not provided with the suppression portion S2 and the return soil S1 alone. Therefore, burdock G with a high commercial value can be obtained.

As described above, the burdock seeding and molding machine 1 according to the present embodiment forms a groove T by digging up the soil at the center of the strip to be seeded in advance, and in the field where the soil (S1) is backfilled in the groove T.

Become. Therefore, the suppressed part (suppressed part S2) absorbs water by capillary action, the roots easily absorb water, can retain a lot of moisture, and the roots extend from the seeds, and the roots are absorbed in the suppressed part. By stretching, it is possible to prevent a fall during the growth. The upper part of the seeded position is covered with the straw molder 50, and since the covering soil (S3) is soft, the germination rate can be increased without hindering the growth of germination, so that the burdock can grow properly. The condition can be adjusted.
In addition, since the burdock seeding molding machine 1 travels while the pressure reducing guide wheel 41 is guided by the groove T during the seeding operation, it is possible to seed at an appropriate position without shifting from the groove T.

  The seeding device (tape laying device 60) is sown by laying the seed tape 2 in which seeds are enclosed in the field.

  Since seeds are seeded in the field with the seed tape 2 in which the seeds are encapsulated, it is difficult to be affected by external factors such as wind, and the seeds are encapsulated in advance at the same interval. Can be sown in place.
