Abstract

PURPOSE:To obtain a high-quality cut flower having long stem by collecting flower while leaving leaf during period difficult in basal shoot and bending branch (from which flower is not collected) near plant root and lodging the branch during the period easy in basal shoot, and growing shoot as branch and cutting the branch from the base to collect the flower. CONSTITUTION:Only bud on branch grown first is taken at initial culture period of rose and the branch is manually bent near a plant root to maintain lodging state and the basal shoot which appears from the vicinity of the plant root is grown as a branch and the branch is cut from the base to collect the flower. After the first collection of flowers, all the branches from which flowers are not collected are bent to maintain in a lodging state and the shoots which appear after collecting the flowers and the shoot which appear newly are grown as branches and these branches are cut from their bases to collect flowers. The above-mentioned processes are repeated thereafter. Operation for cutting branches and collecting flowers is carried out in a form to leave branches and leaves and, thereafter, the operation is repeated. The both operations are combined and performed to carry out cut flower culture of rose.

[Detailed description of the invention]

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

2. Description of the Related Art A conventional method for cultivating cut rose flowers will be briefly explained with reference to FIGS. 8A to 8E.

[0003] Usually 30 to 40 days after planting a rose seedling, buds about the size of a soybean will appear, as shown in FIG. 8A. Therefore, as shown by the dotted line in FIG. 8B, this bud and one or two upper leaves are attached and pinched. In this case, new shoots will appear after the core is plucked. However, because this shoot has a thin mother branch and few leaves left, even if it is grown as a branch, it is too thin and short to collect flowers. FIG. 8C shows such a situation. Then, as shown by the dotted line in FIG. 8D, pinching is continued and flowers can be harvested after pinching at least twice. FIG. 8E shows this situation. However, because many leaves are left on the plant at first, the length of cut flowers is short, making it impossible to obtain high-quality cut flowers with long stems.

[0004] After the first flower collection, the number of new buds that appear after the flowers are collected increases, so a lot of effort is required to clean up and remove unnecessary new buds, which may result in only thin and short cut flowers being obtained. Make sure not to. Furthermore, when collecting flowers, always leave 2 to 3 of the 5 leaves to form a full mother branch. For this reason, the height of the tree gradually increases, and as a result, the flower harvesting position inevitably becomes higher, which impairs the workability of flower harvesting. In addition, branches that have been around for more than a year show significant aging. Therefore, devaluation through pruning was necessary.

[0005]

[Problems to be Solved by the Invention] As mentioned above, the conventional cultivation method takes advantage of the apical-dominant nature of the rose plant, and when it comes to harvesting flowers, branches and leaves are The height of the tree was raised by allowing the apical bud to emerge and growing while leaving the buds in place, raising the flower harvesting position, and raising the tree height. This meant that removing side buds and harvesting flowers took time, making work difficult. Also, because I pruned the tree at least once a year to lower its height, I was only able to collect flowers six or seven times a year. The high construction also obstructed the transmission of light rays passing through the trees, causing uneven temperature inside the bed and variations in the indoor environment. Furthermore,
Because the stem lengths vary from 20 to 80 cm, flower selection takes time and requires thinning, pinching, etc.

[0006] In view of the above circumstances, the present invention allows the flower harvesting position to remain at about waist height, thereby making it possible to continuously harvest high quality cut flowers with long stems with less labor, and to make it possible to harvest flowers throughout the year. The purpose of the present invention is to provide a method for cultivating cut rose flowers that can cope with the various management styles of growers by securing a certain number of flowers through harvesting.

[0007]

[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 that appear near the base of the plant are grown as branches, and flowers are collected by cutting them from the base of the branches.After the first flower collection, all branches that are not used for flower collection are bent to maintain a lodging state, and the flowers that appear after the previous flower collection are grown. The first cultivation method is characterized by growing shoots and newly generated basal shoots as branches, cutting and collecting flowers from the base of the branches, and repeating this process thereafter. The cultivation method is configured to be carried out in combination with a second cultivation method, which is characterized in that the cultivation method is carried out in such a manner as to leave a .

Furthermore, the present invention is configured such that the first cultivation method is carried out during a period when basal shoots are more likely to appear, and the second cultivation method is carried out during a period when basal shoots are less likely to appear.

[0009]

[Function] With the above-described structure, the present invention allows the first cultivation method to receive sufficient sunlight near the plant base, thereby promoting the generation and good growth of basal shoots, and the second cultivation method. When implementing this cultivation method, since there is no pruning, the tree body can be kept in almost the same state, so absorption of fertilizer and water is constant, root elongation is good, and the tree does not lose vigor, so shoots and basal It acts to make it easier to shoot.

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.

Normally, 30 to 40 days after planting a rose seedling, buds about the size of a soybean are formed, as shown in FIG. 1, which is the same as in the past. However, 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), the lodging state can be achieved. 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. By cutting and collecting flowers from the base of the branch 3, high-quality cut flowers with long stems can be obtained. The areas indicated by fine horizontal lines in FIG. 4 are the areas where flowers are harvested, and the areas shaded in black in the figure are the areas that remain after the flowers are harvested.

[0012] After the first flower collection, all branches that are not used for flower collection are bent to maintain the lodging state. In this way, shoots generated after the previous flower harvest and basal shoots newly generated at the base of the plant will occur in an appropriate manner. There is no need to trim the buds. The shoots that emerge after flowering are thick and long, similar to basal shoots. In this case as well, high-quality cut flowers with long stems can be obtained by cutting and harvesting flowers from the base of the branches. The blacked-out areas in Figure 5 are the same areas left after flower harvesting as the blacked-out areas in Figure 4. A location 4 indicated by a fine horizontal line is a location where shoots that will develop after the flowers are harvested will become branches, and the flowers will then be cut and harvested from the base of the branches.

[0013] The above-mentioned operations are repeated in the same manner during seasons when basal shoots are likely to appear (for example, during relatively warm seasons excluding winter).

[0014] In the season when the occurrence of basal shoots is low (for example, in winter), as shown in Fig. 6, the work of harvesting flowers is repeated, leaving two or three of the five leaves, as in the conventional cultivation method. The areas indicated by fine horizontal lines in FIG. 6 are the areas where flowers are harvested, and the areas shaded in black in the figure are the areas that remain after the flowers are harvested. At this time, the height of the tree will increase somewhat if the cultivation method is applied at a time when basal shoots are less likely to occur. 7
As shown in Figure 2, by bending the mother branch at its base after harvesting flowers, the vigor of the rose tree does not decline, making it easier for shoots and basal shoots to emerge. Depending on the condition of the tree and the number of leaves, it may be possible to cut the mother branch at the base at the same time as flower harvesting, but this can be avoided by ensuring the number of leaves is large enough to cause a shock like pruning in normal cultivation.

[0015]

[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. Flowers are harvested by cutting from the base of the branch, and after the first flower harvest, all branches that are not to be harvested are bent to maintain a lodging state, and the shoots that are generated after the previous flower harvest and the newly generated basal shoots are allowed to grow as branches. The first cultivation method is characterized by cutting and collecting flowers from the base of the branch and repeating this process thereafter, and the first cultivation method is characterized by cutting flowers by cutting the branches while leaving the branches and leaves and repeating this process thereafter. Since it is configured to be implemented in combination with the second cultivation method, when implementing the first cultivation method,
Since the area near the base of the plant receives plenty of sunlight, which promotes the development and good growth of basal shoots, high-quality cut flowers with long stems can be obtained from the first harvest while using the first cultivation method. Even after that, shoots or basal shoots are generated one after another after the flowers are harvested, and high-quality cut flowers with long stems can be harvested. In addition, since flowers are always cut at the base of the branches, the efficiency of flower collection work is high, and weak branches are continuously bent, which saves labor in arranging buds. Moreover, since there is no need for pruning and no downtime for pruning, you can collect flowers 9 to 10 times a year.
Provides growers with a substantial increase in income. Furthermore, the light utilization efficiency increases as the height of the tree decreases, contributing to keeping the indoor environment constant. Furthermore, the growth is uniform, the stem length is constant, and special flower selection work is not required. Furthermore, since it is not necessary to collect flowers with about two of the five leaves remaining, flowers that were conventionally collected at 70 cm can be cut at 80 cm or more, making it possible to produce cut flowers with long stems. On the other hand, when implementing the second cultivation method, the tree height will be higher, but by utilizing the conventional characteristic of apical bud dominance, flowers will be harvested with about two of the five leaves remaining, and after the flowers are harvested, flowers will emerge immediately below. By stretching the shoots and collecting flowers, cut flowers can be reliably obtained even when it becomes difficult to secure the number of flowers collected due to unstable basal shoot generation due to continuous implementation of the first cultivation method, etc. Therefore,
While implementing the second cultivation method, it is possible to secure a certain number of flowers.

[0016] Also, the first cultivation method is carried out during seasons other than winter, when basal shoots are more likely to appear, and the second cultivation method is carried out during seasons, such as winter, when basal shoots are less likely to appear. With this configuration, it is possible to suppress the decrease in the number of flowers harvested during the period when basal shoots are difficult to produce, making it possible to secure a certain number of harvested flowers throughout the year, making it possible to cultivate cut rose flowers even if the grower has a small business scale. method can be provided.
