BACKGROUND OF THE INVENTION
The present invention relates to a seedling raising apparatus and relates to a seedling raising equipment useful for raising seedlings by sequentially dividing a first offspring from a parent strain and a second offspring from a first offspring, such as cocoons.
[0002]
[Prior art]
In the case of cocoon raising seedlings, for example, as shown in Patent Document 1, in the seedling raising method in which the sapling is separated from the parental strain in the continuous soil, when the vine touches the soil, it causes damage such as carbon disease There is. Also, when raising seedlings on the ground, the burden on the operator's waist is very severe and harsh.
On the other hand, there is a seedling raising method called the Niagara method. In this method, the parent strain is housed and raised in the uppermost stage of the staircase seedling shelf, the first offspring stocked from this parent stock is raised in the lower pot, and the second offspring stocked from the first offspring is further grown. The seedlings are nurtured in the following lower pot, and this is sequentially divided into the third and fourth substrains, and usually 6 to 8 strains are stocked.
By the way, this strain is divided into (1) the vine grows and grows from the parent strain, (2) the leaf grows from the crown portion of the vine, (3) the root grows from the crown portion and grows into the child strain, (4) The vine grows and grows from the crown portion of the child strain, and the required number of strains are obtained by repeating the above (2) to (4).
In such a stock split, the vines (runners) have variations that are too long or short due to uneven growth, and if the vine length is less than the height of the upper and lower tiers, It will be wasted. In addition, if the vine is too long, it will not be possible to prevent the carbon disease that can occur by touching the soil.
