[0001]
[Industrial applications]
The present invention relates to a method and an apparatus for transplanting rooted seedlings into pots filled with soil, particularly suitable for raising seedlings and suitable for transportation in a distribution process.
[0002]
[Prior art]
For flower seedlings such as pansies, blossoms, and haboton, and self-rooted seedlings such as lettuce, tomatoes, eggplants, and peppers, self-rooted seedlings that have germinated and rooted are placed in pots, and a large number of pots are arranged in seedling trays. They are housed and grown to an appropriate state. The grown seedlings are transported together with the seedling raising tray and planted at a desired location.
[0003]
To raise the pot, the pot is filled (filled with soil), a hole is formed in the soil, and a rooted seedling is dropped into the hole. Then, the root of the root seedling is covered with soil and the pot transplanting operation is completed. In order to increase the efficiency of seedling production, this pot raising operation has been mechanized.
[0004]
For example, Japanese Unexamined Patent Publication No. 8-37937 discloses a soil filling device for automatically filling a pot from the eighth minute to the ninth minute in order to mechanize the pot picking operation. Japanese Unexamined Patent Publication No. Hei 8-37938 discloses a device for piercing soil in a pot for piercing a plurality of pots into which soil is to be planted. Further, Japanese Patent Application Laid-Open No. H10-66455 describes a potting and earth filling device in which soil is supplied into a pot accommodating a drilling unit so that a concave portion for dropping root seedlings is formed.
[0005]
In the soil filling device of JP-A-8-37937, a plurality of pots stored in a tray are raised so that the lower ends of the nozzles enter, and then a soil charging member is moved to a nozzle unit to thereby reduce the number of pots. The soil is poured into a nozzle having a capacity capable of filling the soil from the minute to the ninth minute, and finally, the pot is lowered, so that the above amount of soil is simultaneously contained therein, and It is intended to be automatically packed.
[0006]
In the drilling device disclosed in Japanese Patent Application Laid-Open No. 8-37938, an elevating plate is movably mounted above the earth filling unit, and a drill unit exchangeably mounted on the elevating plate is lowered while being rotated by a drive motor. A uniform hole is simultaneously made in the soil packed in a plurality of pots in a tray below.
[0007]
Further, the earth and sand filling device disclosed in Japanese Patent Application Laid-Open No. H10-66455 discloses a tray on which a plurality of pots are placed, a plate on which earth and sand drop holes are formed, and a position where the earth and sand drop holes correspond to the upper surface opening of the pot in the pot. A punching unit consisting of a convex portion, a lift device for lifting the tray to correspond to the plate, and a stirring member provided therein, and having an opening on the lower surface, and furthermore, a state in which the plate is located on the upper surface of the plate and retreats from the plate. And a sediment storage container that operates in a state.
[0008]
[Problems to be solved by the invention]
However, the above-mentioned conventional pot transplanting method and pot transplanting apparatus may have the following problems. When the medium is filled by the nozzle, the medium in the pot is not sufficiently tightened. On the other hand, when drilling is performed with a drill, the formed planting hole may be broken. Further, in the case of forming using the drilling unit, when the ratio of the diameter of the rooted seedling to the inner diameter of the pot is increased, the amount of the soil filled in the pot is reduced, and the moisture and fertilizer contained in the soil are reduced. And the growth of seedlings may be inhibited. In addition, in any of the pot transplant methods, since the soil of the rooted seedling is not covered with soil, water evaporates from the root of the root, and initial cultivation is delayed, and the seedling may be poorly grown.
[0009]
As a mechanism for forming a planting hole in the soil, there is a mechanism in which a pressure-reducing rod is pressed against the soil to form the planting hole. In the method using the pressure-reducing rod, when soil having a small particle size is used, it is necessary to withstand a large load in order to form a planting hole having a sufficient depth, and the soil may be tightened. There is. If the soil is tightened, it may hinder the root growth of the seedlings.
[0010]
Therefore, the present invention does not disturb the planting holes formed in the soil in the pot, can reliably drop the rooted seedlings, and does not hinder the growth of the root because the soil is not hardened, and It is another object of the present invention to provide a method and an apparatus for transplanting pots of rooted seedlings, which can surely cover the roots of the rooted seedlings dropped in the planting holes and prevent evaporation of water in the root portion.
[0011]
[Means for Solving the Problems]
As a technical means for achieving the above object, the method for transplanting rooted seedlings according to the present invention comprises forming a planting hole in the soil filled in a pot, dropping the rooting seedling into the planting hole, and raising the potted plant.

Further, the root transplant seedling pot transplanting apparatus according to the invention of claim 5 fills a pot with soil, forms a planting hole in the soil, drops the root seedling into the planting hole, and raises the pot. The apparatus comprises: a soil filling means for filling the pot with the soil; a water sprinkling means for sprinkling the soil in the pot; and a hole forming means for forming a planting hole in the sprinkled and wet soil. Features.
[0020]
The soil is filled into the pot by the soiling means, and water is sprinkled by the watering means to wet the soil. A planting hole is formed in the soil by a hole forming means, and a rooted seedling is dropped into the planting hole. Since the soil is hydrated when the planting hole is formed, the formed planting hole does not collapse and the rooted seedling can be reliably potted. In addition, as the burying means, a manual stuffing device or a stuffing device described in JP-A-8-37937 can be used.
[0021]
Further, the root transplant seedling pot transplanting device according to the invention of claim 6 is a pot transplant of a root seedling that fills a pot with soil, forms a planting hole in the soil, drops the root seedling into the planting hole, and raises the pot. In the apparatus, a soil filling means for filling the pot with the soil, a preparation watering means for watering the soil put in the pot, a hole forming means for forming a planting hole in the sprinkled and wet soil, and the planting hole And a complete watering means for watering the roots of the rooted seedlings dropped into the plant.
[0022]
When water is sprayed on the rooted seedling dropped into the planting hole by the completion watering means, the soil at the upper edge of the planting hole is broken and falls into the planting hole. As a result, the root of the rooted seedling is covered with soil. In addition, the preparation watering means and the completed watering means may also be used.
[0023]
Further, in the pot transplanting layer for rooting seedling according to the invention of claim 7, the hole forming means forms a planting hole by drilling a hole in the soil with a drill.
[0024]
Since the implantation hole is formed by rotating the drill, it is possible to easily form the one having a desired diameter and depth. Moreover, since the soil removed for the planting hole is piled up on the upper edge of the formed planting hole, it is easily broken by breaking the soil to the root of the rooted seedling dropped into the planting hole. Soil can be covered in a reliable manner.
