[0013]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a method for cultivating cut rose flowers according to the present invention will be described with reference to the embodiments shown in the drawings. 1 to 8 show an embodiment of the present invention. As shown in FIG. 1, a branch for cutting a rose is inserted into a cutting block 3 and managed for a predetermined period to cause rooting to obtain a rose seedling 1. This cutting block 3 is made of rock wool.

Next, as shown in FIG.
Is transferred to the hydroponic cultivation apparatus 5 for planting. Hydroponics equipment 5
Will be described. A discharge pipe 9 is attached to the bottom of the cultivation tank 7. Further, a mat 11 made of rock wool is arranged in the cultivation tank 7. The cutting block 3 is arranged on the mat 11 and planted. A portion of the mat 11 other than the portion where the cutting block 3 is disposed is covered with a styrene foam plate, a resin sheet, or the like. The water or liquid fertilizer supply nozzle 13 is fixed to a support shaft 15, which is inserted into the cutting block 3. A hose 17 is connected to the supply nozzle 13 to supply a predetermined amount of water or liquid fertilizer. In the following description, it is described as water or liquid fertilizer, but it is determined whether to supply water or liquid fertilizer depending on the variety of rose, cultivation conditions, growth degree, etc., and further, the type and concentration of the liquid fertilizer adjust.

The water or liquid fertilizer supplied from the supply nozzle 13 penetrates the cutting block 3, and excess water or liquid fertilizer is absorbed by the mat 11 and stored in the cultivation tank 7. The water or liquid fertilizer in the cultivation tank 7 is discharged from the discharge pipe 9, and a constant level of water or liquid fertilizer is maintained.
For one to three weeks after planting, raise the level of water or liquid fertilizer to the same level as the top of the mat 11,
Conduct constant water management to maintain that level. This allows the cultivation tank 1
The concentration and amount of water or liquid fertilizer in the plant are stabilized so that the growth of the rose seedling 1 is not hindered. Also,
For a predetermined period after the constant water management, the water or liquid fertilizer in the cultivation tub 7 is gradually drained to promote the elongation of the root 19. That is,
A cap 21 having a small gap is attached to the discharge pipe 9, and water or liquid fertilizer is gradually discharged from this gap. The water level of the water or liquid fertilizer is gradually lowered between 10 days to 15 days. The roots are stretched to follow the liquid fertilizer to promote the roots 19 to grow. This period is adjusted from one week to three weeks.

After planting, the first growing branch 27 grows,
As shown in FIG. 3, during the period from flowering to full bloom, the flowers 23 and the buds 25 are all pinched (fuller ring and reshooting) to perform a pinch step. After the pinch process is completed, the branch 27 is left for 2 to 5 days, and then, as shown in FIG.
The lodging process is performed by twisting and bending in a range of 3 cm to 20 cm from the germination position to the tip direction. It is considered that such a period of time is left for a predetermined period because it is necessary to return a nutrient moved to the distal end side of the branch 27 to the base end side of the branch 27 due to flowering and growth of the bud 25. The bending direction in which the branch 27 is twisted is a direction in which spiral fibers in the circumferential direction of the branch are wound (closed), and the branch 29 is prevented from breaking. When the branches 27 are laid down, the growth of the adventitious buds is promoted, and a basal shoot 29 is generated. If there are two or more basal shoots 29,
The flowering mother branch is determined and flowers are collected.

As shown in FIG. 5, after the lodging step, when the number of the generated basal shoots 29 is one and is about 5 cm to 10 cm, the basal shoots 29 are pinched near the root to remove other sub shoots. The growth is promoted, and a plurality of basal shoots 29 are generated.

As shown in FIG. 6, after the lodging process, only one basal shoot 29 was generated, and the one that grew until the buds were attached was pinched by the flowers and buds 25 immediately before flowering, and for 2 days to 5 days. After being left for a few days, it is twisted and bent to fall down and reprocessed to generate a plurality of new basal shoots 29. Even though the reprocessing described in FIG. 6 was performed, if only one basal shoot 29 was generated as shown in FIG. Promotes the growth of shoots and promotes the development of new basal shoots.

In the above description, if the number of the generated basal shoots 29 is one after the falling-down step, the pinch is performed, and
In the case of a book, it is a flowering mother branch, but the number of flowering mother branches in a basal shoot to be generated is not limited to two, and may be three or more. After the start of flowering,
If the roots 19 in the mat 11 cannot be kept growing properly, the drain pipe 9 is plugged so that the mat 11 is sufficiently immersed in water or liquid fertilizer. Pull it out and adjust the level of water or liquid fertilizer so that it is 1 cm to 3 cm above the lower surface of the mat 11. Thereby, the growth of the root 19 in the mat 11 is promoted, and the smooth growth can be maintained.

Referring to FIG. 8, a pruning method performed after the second year after the completion of flowering will be described. Basal Shoot 29
Is cut so as to have a constant height, only one basal shoot 29 is cut, and the remaining basal shoot 29 after a predetermined period has elapsed is cut.
As a result, a considerable amount of water absorbed from the root 19 is
Escape to the basal shoot 29 left uncut,
Prevents moisture from blowing from the cut.

Further, after the second year, the grown branches are
3cm from the sprout position of the branch that has passed one year, as in the year
A flowering mother branch determining step of determining a flowering mother branch from a plurality of basal shoots generated below the torsion bending part after twisting and bending the branch in a range of about 20 cm tip direction; Then, a flower-collecting step of collecting flowers from the mother branch is performed.

Although the embodiment of the present invention has been described in detail above, the specific configuration is not limited to this embodiment, and even if there are changes within the scope not departing from the gist of the present invention, the present invention is not limited to this embodiment. Included in the invention. For example, in the above embodiment, the case of cutting is shown, but the present invention can be applied to the case of grafting.
