When the number of developed leaves of the primary shoots b is still about seven, the respective nodes such as the sixth, seventh, eighth, etc. from the sixth paragraph onward are still concentrically contained in the fifth paragraph, In other words, they are located in concentric rings like annual rings. Incidentally, the top bud growth point of the primary shoot b is present in the fifth node, but cannot be visually judged from the outside since it is covered with bud bracts. However, empirical rules have confirmed that cutting off the apical growth point by cutting at the midpoint between the overlapping portions of the fourth and fifth bracts is possible. In general, in the shoots of sugar cane, the sprouts and roots are present for the first time in the sections from section 5 onward.

[Tertiary branch shoots and cutting treatment as pre-seedling management] Tertiary shoots d, which is a large amount of higher shoots collected from a large number of mother shoots in accordance with the above-described procedures, have survived by transplanting to this field. The seedlings are grown in higher branch shoots where the roots necessary for self-sustained growth are elongated.
For each of the same number of leaves, ie, 1 leaf, 2 leaves, 3 leaves, 4
The leaves and the five leaves are classified in advance. this is,
In the subsequent raising of seedlings, when trying to raise seedlings in the same single collective raising equipment with different numbers of leaves, the rooting is significantly delayed due to shade and insufficient photosynthesis due to the low number of leaves. This is to avoid dying.

[Nurture] Higher order shoots, which are tertiary shoots d collected from the mother shoots, are rooted on the higher order shoots, and the higher order shoots with roots necessary for growing and growing in this field as described above are extended. In order to make the stems and seedlings, the inventors conducted experiments using various collective seedling raising devices. As a result, among the above three types of collective seedling raising equipment, a large number of storage portions are formed by a large number of paper cylinders, and each of the storage portions can be separated (Japanese sugar beet sugar). Co., Ltd., registered trademark “Paper Pot”), and one of them has a diameter of 3c.
It has been found that a collective seedling raising device f in which a total of 264 pieces are arranged in a honeycomb array with 12 pieces of paper cylinders 12 having a height of 10 cm and a length of 12 pieces in a column and 22 pieces in a row is optimal for the seedling raising of this example. .

The temperature in the seedling raising house g is maintained at 25 to 30 ° C. to avoid a rapid temperature change, and watering is performed immediately after the arrangement of the collective seedling raising equipment f in the seedling raising house is completed. The day was sufficiently performed day and night, and from the second day, the operation was performed every hour for about 10 minutes only in the daytime, and nighttime irrigation was not performed. Thus, the tertiary shoots d rooted 4 to 7 days after the planting in the spring and 3 to 5 days after the planting in the summer. After 10 days of planting in spring and 7 days after planting in summer,
Watering was enough to prevent the leaves from withering.

Further, three days before transplantation to the main field, the seedlings were trimmed so that the seedling length became approximately 25 to 35 cm (FIG. 1).
8) Thus, preparation is made so that the automatic transplanting operation to the main field by the dedicated transplanter can be smoothly performed. However, when the seedling length is cut to about 25 to 35 cm as described above, the higher-order shoots h that have grown to a height at which the first developed leaves hardly exist will survive even when transplanted to this field. As such, the higher-order shoots h are not cut off, but are removed as a single collective seedling raising device f including the same, and are prepared for use as seedlings for supplemental planting as they are.

The dedicated transplanter is of a tractor traction type, and is equipped with a seedling separation mechanism, an individual seedling separation mechanism, a seedling planting mechanism, a groove forming mechanism, and the like, which are automatically driven as the vehicle runs. Transplanting is performed by the above-described seedling separation mechanism.
Of paper cylinders 12 are collectively separated in units of rows, that is, every 22 rows, separated individually by a seedling separation mechanism, and sent to a seedling planting mechanism.
Pre-excavation groove width 75-80cm at 40-150cm,
At the bottom of the furrow 15 having a depth of about 25 cm, the higher branch shoots h together with the above-mentioned paper cylinder 12 are continuously provided at a required interval, and with the upper part of the paper cylinder 12 being exposed at about 2 cm.

As is apparent from the above description,
According to the present invention, the following effects can be obtained. (A) A large number of higher order shoots are intensively clustered at the nodes of the stalk (mother), so that the higher order shoots can be efficiently collected without much trouble. (B) In raising seedlings in the seedling raising house, the seedlings are inserted and planted separately in the higher-order shoots having the same number of leaves, and the required interval between the collective seedlings that accommodates the higher-order shoots having the same number of leaves is maintained. Since the plant is installed with a gap and is initially managed not to fertilize it so as to promote rooting, it is necessary to obtain higher shoots that have almost the same seedling length and have a large number of branch roots necessary for survival. Can be. (C) Since the higher-order shoots are taken out of the nursery house before transplanting to the main field and are acclimated, that is, adapted to environmental changes, each seedling is surely settled and grown in the main field. (D) Since the seedling height is adjusted by, for example, shearing leaves so as to be approximately 25 to 35 cm, automatic transplantation to the main field by the dedicated transplanter can be performed smoothly. (E) By performing the above-described shearing treatment, only higher-order shoots excluding those that almost lose the first developed leaves are transplanted, so that 95% or more can be energized and a high yield can be expected.
