Abstract

PURPOSE:To increase the number of cut flowers without excessively lowering the quality of the cut flowers of a rose. CONSTITUTION:All branches 2,3 excluding a mother branch for collecting flowers are maintained in fallen states, and a basal shoot newly generated at a stage securing a prescribed number of leaves is raised as a branch 4. Only the bud of the branch 4 is removed. Lateral buds generated on the branch 4 are raised as branches 6 and cut at the basic parts thereof to collect cut flowers, whereby plural cut flowers are obtained from a thick mother branch 4 (namely, mother branch for collecting the flowers). The mother branch after the collection of the flowers is bent at the basic part thereof, and the same operations are repeated.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for cultivating cut rose flowers in a greenhouse or greenhouse to obtain cut rose flowers.

0002

BACKGROUND OF THE INVENTION In the rose cut flower market in Japan, the quality of individual cut flowers is generally considered important, and the price difference between so-called high-quality flowers and those of lower quality is too large. For this reason, growers have traditionally attempted to improve the quality of each flower by reducing the number of cut flowers by bud plucking. That is, unless the mother branch is quite thick, the quality and arrangement of flowers are improved by removing all buds and leaving only one apical bud to limit the number of flowers collected.

0003

[Problems to be Solved by the Invention] However, although high-quality cut flowers can be obtained with this method, the yield (number of cut flowers) per unit planting area is limited, so the scale of the grower's business and management Depending on the form, this may not necessarily be an appropriate cultivation method.

SUMMARY OF THE INVENTION In view of the above-mentioned circumstances, an object of the present invention is to provide a method for cultivating cut flowers that can significantly increase the number of flowers harvested without significantly reducing the quality of cut flowers.

[0005]

[Means for Solving the Problems] That is, the present invention removes only the buds of the branches that first grow during the early stage of rose cultivation, and artificially bends the branches near the base of the plant to maintain the lodging state.
Basal shoots generated near the base of the plant were allowed to grow as branches, all branches were bent to maintain a lodging state, and once a predetermined number of leaves were secured, newly generated basal shoots were allowed to grow as branches and elongate. Take only the buds of the branches, extend the side buds that develop on the branches, grow them as branches, cut the flowers from the base of the branches, and after collecting the flowers, bend the mother branch at the base, and repeat this process from now on. configured.

[0006]

[Operation] With the above-mentioned configuration, the present invention allows the vicinity of the plant to receive sufficient sunlight during the growth process of the mother branch, and
By ensuring a certain number of leaves, the absorption of fertilizer and water is constant, and the rose tree will not lose its vigor.
It acts to promote the development and good growth of basal shoots, which serve as mother branches for flower collection.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings shown in FIGS. 1 to 7.

Usually 30 to 40 days after planting a rose seedling, buds about the size of a soybean will appear, as shown in FIG. Therefore, by pinching only the bud 1 drawn by the dotted line in Fig. 2, and artificially bending the branch 2 near the base of the plant, for example, by tying the branch 2 to a support (not shown), etc. be maintained. After bending, a basal shoot occurs from the base of the stock. The area indicated by a fine horizontal line in FIG. 3 is the branch 3 on which this basal shoot has grown.

[0009] When the basal shoots have grown as branches 3 in this way, all the branches 3 are artificially bent near the base of the plant to maintain the lodging state. In this way, new basal shoots are generated from the base of the plant when a predetermined number of leaves are secured. The locations indicated by fine horizontal lines in FIG. 4 are the branches 4 on which these basal shoots have grown. During the growth process of this branch 4, as shown in Fig. 4, all branches 2 and 3 other than this branch 4 maintain a lodging state, so that the vicinity of the base of the plant receives plenty of sunlight and By ensuring a sufficient number of leaves, the absorption of fertilizer and water is constant, and the rose tree's vigor will not decline, which will encourage the occurrence of basal shoots and their good growth. As a result, the branch 4 becomes thick and long. Next, as shown by the dotted line in FIG. 5, only the buds 5 of this branch 4 are pinched, and a plurality of side buds generated on this branch 4 are extended. The areas filled in black in FIG. 5 are the branches 6 on which these side buds have grown. When these branches 6 reach a predetermined stem length, these branches 6 are cut from their bases and flowers are harvested, as shown by dotted lines in FIG. By doing this, a plurality of cut flowers can be obtained from one branch 4 (namely, the mother branch). When all the branches 6 have been cut and harvested, as shown in FIG. 7, the branch 4, which is the mother branch after the flowers have been harvested, is artificially bent at its base to maintain its lodging state.

[0010] The above-mentioned operations are repeated throughout the year thereafter.

[0011]

[Effects of the Invention] As explained above, according to the present invention,
In the early stages of rose cultivation, only the buds of the branches that first grow are removed, and the branches are artificially bent near the base of the plant to maintain a lodging state, and the basal shoots that emerge from the base of the plant are allowed to grow as branches. All the branches are bent to maintain the lodging state, and when the specified number of leaves are secured, the newly generated basal shoots are grown as branches, and only the buds of the elongated branches are removed, and the side buds that appear on the branches are removed. The structure was constructed by growing the branch as a branch, cutting the flower from the base of the branch, bending the mother branch at the base after collecting the flower, and repeating this process. By providing plenty of sunlight in the vicinity and ensuring a certain number of leaves, the absorption of fertilizer and water is constant, and the rose tree's vigor does not decline, resulting in the formation of basal shoots that serve as mother branches for flower collection. and its good growth. Therefore, it is possible to obtain thick and long mother branches,
Furthermore, by utilizing many axillary buds that develop on the mother branch as cut flowers, it is possible to improve the quality of cut flowers using normal cultivation methods (i.e.,
Compared to methods in which only one apical bud is left by scraping the buds to improve arrangement, it is possible to significantly increase the number of flowers harvested without significantly reducing the quality of cut flowers, and the scale of the grower's business can be increased. It is possible to provide a cultivation method that is sufficiently profitable even when there is no such thing. In addition, all branches that do not become flower-collecting mother branches are bent near the base of the plant, which increases the light utilization rate and improves the environment inside the greenhouse. Furthermore, since the flower harvesting position does not become progressively higher as in the conventional method of cultivating cut rose flowers, that is, the usual height cultivation method, there is no need for pruning, and the work efficiency for flower harvesting is improved.
