  FIG. 6 is a schematic cross-sectional view (part 3) of the power supply drive type cultivation apparatus 300 of the embodiment in the present invention, and FIG. 7 is a schematic view of the power supply drive type cultivation apparatus 300 of the embodiment in the present invention. FIG. 8 is a schematic perspective view of a power supply drive type cultivating apparatus 300 according to an embodiment of the present invention.

  FIG. 6 is a cross-sectional view taken along the line A-A. And in FIG. 6, the power supply drive type cultivation apparatus 300 in the state in use is shown.

  The root cutting cutting wire 341 is a narrowable wire provided at a predetermined distance δ1 downward from the position at which the seed 20 is held.

The predetermined distance δ1 is determined in accordance with the position at which the root should be cut for the main root 31 extended downward so as to be a support from the seed 20 held in the vicinity of the surface of the field soil S. In one embodiment,
(1)
δ1 = 0.5 [mm]
Is adopted.

  The principle for narrowing the root cutting wire 341 is, for example, as follows.

  That is, one end of the root cutting wire 341 is connected to the root cutting cutting wire winding shaft 341b through the root cutting cutting wire guide ring 341a, and the other end of the root cutting cutting wire 341 is the root cutting cutting wire guide ring 341a. It is connected to the. When the cutting wire winding shaft 341b for cutting the root is rotated in the direction of arrow X using a motor, the cutting wire 341 for rooting is wound in the direction of arrow Y and narrowed in the direction of arrow Z, and the root is cut It will be.

  Such rooting is performed, for example, approximately two weeks after seeding is performed. The control unit 350 may perform control for narrowing the cutting wire 341 for rooting based on the result of sensing by the sensing unit 370, or narrows the cutting wire 341 for rooting based on the result of communication by the communication unit 380. You may control to do.

Of course, the result of sensing regarding the growth degree of the main root 31 is transmitted to the side of the multicopter 100, and a control signal for narrowing the cutting wire 341 for rooting is generated based on the result of sensing and transmitted to the power supply drive type cultivator 300 It may be done.

  When rooting is performed, many lateral roots 32 have not yet occurred, but after rooting is performed, many lateral roots 32 are generated to sufficiently absorb fertilizer 320a through the field soil S.

  The pinching cutting wire 342 is a constrictable wire provided at a predetermined distance δ2 upward from the position where the seed 20 is held.

The predetermined distance δ2 is determined in accordance with the position at which the picking should be performed on the true leaf 42 which extends from the seed 20 held in the vicinity of the surface of the field soil S and extends upward from the bifoliate 41. In one embodiment,
(2)
δ2 = 35 [mm]
Is adopted.

  The principle for narrowing the cutting wire 342 is similar to, for example, the principle for narrowing the cutting wire 341 for rooting.

  That is, the core cutting wire 342 is wound and narrowed in the same manner as the root cutting wire 341.

  Such pinching is performed, for example, approximately twenty-three days after the above-described rooting is performed. The control unit 350 may perform control for narrowing the cutting wire for cutting 342 based on the result of sensing by the sensing unit 370, or may narrow the cutting wire for cutting 342 based on the result of communication by the communication unit 380. You may control to do. More specifically, the power source drive type cultivation apparatus 300 recognizes (1) the result of sensing regarding the growth degree of the true leaf 42 detected using an optical sensor or the like, and narrows the cutting wire 342 for pinching The active operation may be performed autonomously, or (2) a control signal for narrowing the cutting wire 342 may be received from the side of the multicopter 100 to perform a passive operation. Of course, the sensing result on the growth degree of the true leaf 42 is transmitted to the side of the multicopter 100, and a control signal for narrowing the tipping cutting wire 342 is generated based on the sensing result, It may be sent.

  When pinching is performed, the side branches 50 respectively resulting from the new true leaf 42 accompanied by the pinching have not yet occurred, but after the rooting is performed, two or three side branches 50 are used instead of one main branch. The resulting soybean seeds are fully ripened.

  Thus, not only do many lateral roots 32 arise and absorb enough fertilizer 320a through field soil S, but two or three lateral branches 50 occur instead of one main branch and each fully bears soybean meal. So, approximately 600 (= 200 x 3) grains of soybean are harvested from one strain of soybean 10 which is produced from one grain of soybean.

  The yield of soybean in the present embodiment is approximately three to four times the yield of soybean by a conventional soybean cultivation method, and a highly productive soybean cultivation method is realized by application of a semiconductor process.

  In addition, although the crop of this invention is soybean 10 which arises from the seed 20 in this Embodiment mentioned above, it may be a crop which arises from a bulb, for example.

  In the embodiment described above, the pruning of the present invention is, for example, pruning performed after rooting of the seed 20 and pruning performed after germination of the seed 20, for example, It may be a rooting performed after the rooting of the bulb, and a pruning for performing a pickling performed after germination of the bulb.

  Moreover, although the power supply drive type cultivation apparatus of this invention is the power supply drive type cultivation apparatus 300 containing the communication unit 380 in this Embodiment mentioned above, for example, as shown in FIG. It may be a power supply drive type cultivation apparatus which does not include a unit.

  Here, FIG. 11 is a block diagram (the 3) of the power supply drive type cultivation apparatus 300 of another embodiment in this invention.
