Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a method for growing seedlings.

[0002]

2. Description of the Related Art Conventionally, seedlings have been separated and collected from a mother having a large number of seedlings, and the collected seedlings have been directly transplanted to a field. For example, in the case of sweet potato, the seed potato to be the mother is raised in an appropriate nursery bed, the vine-like seedlings that grow from the seed potato are picked, and the picked vine-shaped seedlings are transferred to the field. Had been transplanted directly.

[0003]

In the above-mentioned conventional case, if the collection of seedlings from the mother is collectively performed before transplanting to the field, the collected seedlings may become damaged as the transplantation proceeds. However, there is a problem that the yield is reduced.
In addition, when transplanting to a field while collecting seedlings from the mother one by one, the work efficiency is inferior and the planted area cannot be increased.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention separates and collects seedlings from a mother having a large number of seedlings, and collects the collected seedlings in a large number of pots. Is inserted into each pot of the seedling raising frame provided with the above from above, and each pot is grown in a state supported by the floor material packed in each pot, and then the seedlings of each pot grown are transplanted to the field. A method of raising seedlings, characterized in that:

[0005]

According to the present invention, the method of growing seedlings described above allows seedlings collected from a mother having a large number of seedlings to be temporarily transplanted to each pot of a seedling frame without directly transplanting to a field. The seedlings in each pot are then transplanted to the field as they are when transplanted to the field. Is less likely to occur, and the conventional problem of yield reduction can be solved.

Moreover, since the seedlings collected from the mother are inserted into the respective pots of the seedling raising frame from above, it is easy to transfer the seedlings collected from the mother to the respective pots of the seedling raising frame. Seedlings inserted into pots are less likely to fall down because they are supported by the flooring material packed in each pot,
Therefore, seedlings can be satisfactorily grown. And, since the seedling frame in which the seedlings are grown in each pot can be brought to the field and transplanted to the field, and the seedlings of each pot can be transplanted to the field as they are, it is efficient in terms of work efficiency, and the planting area can be expanded. I can do it.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As an embodiment of the present invention, a method for growing sweet potato seedlings will be described in detail with reference to the drawings.
Numerals 1a and 1b denote seedling raising frames, and a pot 2a in which one of the upper and lower sides is independent at a predetermined pitch in the left, right, front and rear, and the other is connected to each other
Alternatively, it is an aggregate of 2b. The seedling raising frame 1a is a vine-shaped seedling 1.
It is an assembly of pots 2a for 1a. The seedling raising frame 1b is
Pot 2b for small seedlings usually used for cultivation of vegetables etc.
Is an aggregate of These are formed by dissolving pulp or waste paper, and are found to corrode in the soil. The pot 2a of the seedling raising frame 1a includes left and right side surfaces 3a,
3b, front and rear side surfaces 3c, 3d, and a rectangular front and rear bottom surface 4a having a long hole 5a for cutting, and the vertical cross section is trapezoidal. Pot 2b of seedling raising frame 1b
Similarly, is formed by four side surfaces 3e... And a square bottom surface 4b having holes 5b for cutting, and the vertical cross section is trapezoidal. The height of the vine-shaped seedling pot 2a is relatively high, and the pot capacity is larger than that of the conventional vegetable pot 2b. It is desirable that the sweet potato seedlings have as many as possible nodes on the stem where adventitious roots are likely to occur.
This is a long pot as described above for cutting 1a into a pot like a bottom planting. Here, the seedling raising frames 1a and 1b are composed of an aggregate of the pots 2a or 2b, but may be independent pots one by one. Further, the specific shape of the pot is not limited to a trapezoidal box as shown in the figure.

[0008] Reference numeral 6 denotes a bed soil packed in pots 2a ... or 2b ... which contains fertilizers suitable for growing sweet potato seedlings. Reference numeral 7 denotes a mesh filled in the gap between the pots, which is coarser than the floor soil 6 so as to improve water permeability during irrigation. 8
Is a seedling raising box in which the seedling raising frame 1a or 1b is to be inserted, which is formed of a synthetic resin and has a large number of water holes 9 at the bottom. Numerals 10a and 10b are pot nursery beds which are filled with seedling raising frames 1a and 1b and floor soil 6 and mesh soil 7 and placed in a seedling raising box 8.

Reference numeral 11a denotes a seedling a elongated from a sweet potato seed A.
Is a vine-like seedling with multiple nodes on the stem. Reference numeral 11b denotes a single-leaf seedling obtained by separating the vine-like seedling 11a at a node of a stem from which a leaf is protruded for each leaf. Reference numeral 12 denotes an adventitious root generated from a node or the like of a stem of a seedling. Reference numeral 13 denotes a new bud emerging from a node of the stem of the single-leaf seedling 11b. At this time, the adventitious roots 12 have already grown, and the initial leaves 14 that have been cut into the single-leaf seedlings 11b are dead. Fifteen
a and 15b are pot seedlings obtained by cutting the vine-shaped seedling 11a or the single-leaf seedling 11b into the pot 2a or 2b and raising them. 16
Is a cultivation field. From this, sweet potato seedling 15a
The process up to obtaining is described.

First, the seedling raising frame 1a shown in FIG. 1 is placed on a suitable plate, and the floor soil 6 is packed with the connecting surfaces of the pots 2a. Then, the seedling box 8 is put over and turned upside down to fill the gaps between the pots 2a. FIG. 3
The pot nursery 10a shown in FIG. on the other hand,
As shown in FIG. 5, the seedlings of sweet potatoes were seeded on another suitable nursery bed.
From which the vine-shaped sweet potato seedlings 11a are collected. As shown in FIG.
The seedlings are cut into the pots 2a so that the base side of the seedling lies in the floor soil 6. Then, the seedling management such as temperature and humidity is properly performed in the seedling raising house, and each pot 2 is controlled as shown in FIG.
In step a., an adventitious root is generated in the sweet potato seedling 11a. Thus, a sweet potato seedling 15a is completed.

The vine-shaped sweet potato seedling 11a can be further divided and used as a seedling to be cut into a pot. That is, as shown in FIG. 8, a pot seedling 15b can be made from a single-leaf seedling 11b obtained by cutting off the left and right sides at the node of the stem from which the leaves of the vine-shaped sweet potato seedling 11a are protruding. First, a pot nursery bed 10b is constructed as shown in FIG. 4 using a nursery frame 1b, which is an aggregate of small pots 2b... As shown in FIG. As shown in FIG.
b and transplanted into each pot 2b, and appropriately manage the seedling raising in the same manner as described above. And when the adventitious root 12 begins to occur,
As shown in FIG.
Comes out and attaches leaves, and the initial leaves 14 planted in the pot 2b wither. As described above, the potted seedling 15b can be made by collecting the single leaf seedling 11b from the large sweet potato seedling 11a in the form of a vine. In this method, the period of raising seedlings to generate adventitious roots in each pot is longer than in the case where the above-mentioned vine-shaped seedlings 11a are directly cut into pots, but the number of seedlings necessary for transplanting to the pot raising bed 10b is increased. The number of seed potatoes A can be considerably reduced. The pot seedlings 15b made of the seedling raising frame 1b of the small pots 2b... Are not entangled with the seedlings of the adjacent pot 2b because the seedlings do not grow long, so that they are suitable as seedlings used for mechanical transplantation.

The sweet potato seedlings 15a or 15b obtained as described above are cut into individual pots and transplanted to the cultivation field 16 as they are. Therefore, the transplanted sweet potato seedlings already have adventitious roots at the time of transplantation.
As shown in FIG. 11, since the roots only grow in the soil of the field 16, the roots can be surely and quickly settled on the field 16.

The following effects are obtained by raising sweet potato seedlings as described above. That is, a large number of seedlings (saplings) a
The seedling is separated and collected from the mother (seed potato) A that has grown.
The collected seedlings 11a or 11b are put into a large number of pots 2a.
Or 2b... Is inserted from above into the floor material (floor soil) 6 in each pot of the seedling raising frame 1a or 1b provided with the seedlings, and each pot is grown. By transplanting, the seedlings collected from the mother are not directly transplanted to the field, but are once raised in each pot of the seedling raising frame, and then when transplanted to the field, the seedlings in each pot are transplanted. Is transplanted to the field as it is, so that the seedling is less likely to suffer pain with the lapse of time during the transplanting operation to the field, and the conventional problem of yield reduction can be solved.

Moreover, since the seedlings collected from the mother are inserted into the respective pots of the seedling raising frame from above, it is easy to transfer the seedlings collected from the mother to the respective pots of the seedling raising frame. Seedlings inserted into pots are less likely to fall down because they are supported by the flooring material packed in each pot,
Therefore, seedlings can be satisfactorily grown. And, since the seedling frame in which the seedlings are grown in each pot can be brought to the field and transplanted to the field, and the seedlings of each pot can be transplanted to the field as they are, it is efficient in terms of work efficiency, and the planting area can be expanded. I can do it.

In addition, since the sweet potato seedlings 11a or 11b are cut into the nursery beds 10a or 10b, and adventitious roots are generated there and then transplanted to the field 16, the survival in the field 16 is reliable and quick. Therefore, the seedlings can be satisfactorily activated without being greatly influenced by the weather, and the yield can be increased and stabilized. Further, in growing the pot seedlings 11a and 11b, since one seedling raising box 8 can be handled as an independent management unit, the spread of disease can be suppressed. In addition, since the pot seedlings 11a and 11b are arranged in order on the left, right, front and rear, eyes of each of the seedlings are carefully observed, and it is easy to confirm the growth state. Further, this method is suitable for management in a nursery house or the like, and can be used efficiently in a management space. Therefore, the pot seedling 11a or 1
When growing 1b, temperature, humidity, etc. can be intensively managed, and it is easy to grow healthy and balanced seedlings efficiently.

Further, since the pots of the pot seedlings 11a or 11b are arranged at a predetermined pitch on the left, right, front and rear, highly efficient mechanization of the seedling supply section in the seedling transplanting machine is enabled. That is, it is relatively easy to apply the technique of the rice or vegetable pot seedling transplanter to realize the sweet potato transplanter.
