ので、95%以上を活着させ、高収穫量を期待できる。As is apparent from the above description,
The present invention has the following effects. (A) Since a large number of shoots are intensively grouped in the node portion of the stalk (mother shoot), the shoots can be efficiently collected without much trouble. (B) When raising seedlings in a seedling raising house, the seedlings of the same number of leaves are planted by inserting them into a collective seedling raising device, and the set of seedling raising devices accommodating the same number of leaves of the stems are installed at a required interval. Moreover , since rooting is managed by not intentionally applying fertilizers at the beginning, it is possible to obtain a shoot with a substantially equal seedling length and a large number of branched roots necessary for rooting. (C) Before transplanting the shoots to the main field, they are taken out from the nursery house to be acclimatized, that is, to adapt to environmental changes, so that each seedling is firmly rooted and grown in the main field. (D) Since the seedling height is adjusted to be approximately 25 to 35 cm by defoliation, it is possible to smoothly perform the automatic transplanting work to the main field by the dedicated transplanter. (E) By performing the leaf-scissing process as described above, only the shoots of the shoots and stems excluding the ones in which the first developed leaves are almost eliminated are transplanted, so that 95% or more can be engrafted and a high yield can be expected.
