Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cultivation site for cultivating cut flowers of bulbs.

[0002]

2. Description of the Related Art Cut bulbs are widely cultivated by farmers as items for sale. The cultivation method is generally planted directly on the ground. In this case, for example, when cultivating on the same ground for many years in greenhouse cultivation or the like, the growth of the crop becomes poor due to continuous cropping failure, resulting in a decrease in quality and a decrease in productivity. As one of the measures, a method of cultivating a cultivated area in a container and cultivating cut bulbous flowers there has been performed. (Here, this method is called box cultivation.)

In this box cultivation method, it is not always necessary to place the planted container on the ground, but the work environment can be improved by placing the plant on a bench or the like, or by moving the container to a cultivation environment according to the growth stage. It is also used for the purpose of efficiently using facilities such as greenhouses.

[0004]

FIG. 1 is an explanatory view showing a conventional box cultivation method and a tulip cut flower cultivation as an example. Cultivation area 3 for bulbs in containers 2 of various shapes and capacities
The bulbs are planted at an appropriate planting density. After that, they are brought into a greenhouse or the like in an environment suitable for growth and cultivated. In this process, the operation of moving the container containing the cultivation area is always performed, and the weight of the container in which the soil is cultivated is the general planting density, and the container capacity is 20 per unit.
Since the weight is about 30 kg to 30 kg, the more the cultivation quantity is, the more the moving work is accompanied by great fatigue. Therefore, light materials other than earth and sand are used for the cultivation area, and light materials are mixed with the earth and sand to reduce the weight.

However, since the cultivation area is light, the weight of the cultivation area is reduced, so that the strength of supporting the above-ground portion 1 of the grown tulip is weakened, and as shown in FIG. To do. At the time of harvesting, it is common to extract and harvest the bulbs together to keep them fresh before shipping. However, as shown in Fig. 3, when the tulips are harvested at the right time, the roots are intertwined in the container. Adjacent tulips may fall out or fall together. Curling of the tulip by slipping out or falling down degrades the quality of the cut tulip flowers, resulting in a large loss in sales. This problem is also found in other bulb-cut flower cultivation, and is to be solved by the present invention.

[0006]

The above-mentioned problem is caused by the fact that the lighter the cultivation area is, the weaker the supporting power of the cultivation area which is rooted with respect to the above-ground portion of the bulb is. is there. In addition, since the cultivation area is light at the time of harvesting, the roots are not cut off and are attached to the above-ground portion where the bulbs are extracted and harvested, resulting in pulling down adjacent ones.

Therefore, as shown in FIG. 4, the cultivation area is divided into a floor soil layer 6 in which the roots of the bulbs extend and a covering soil layer 5 above the floor soil layer 6, and a reinforcement 7 is installed on the floor soil layer to reinforce the soil. Bulb 4 on the fixture
The problem was solved by planting and covering the soil, thereby supplementing the force of supporting the bulb above the cultivation area.

[0008] The reinforcement is a space 8 where the bulbs are planted.
And the bulbs are planted above the space, so that the roots extend through the space of the stiffener and extend in the lower floor soil layer and entangle with the roots of the adjacent bulbs. Therefore, the bulb is firmly fixed to the reinforcing device by the rooting site and the root extended to the floor soil layer. In addition, even if the above-ground part is pulled out together with the bulb at the time of harvesting, the root part does not pass through the space 8 of the reinforcing tool, and the reinforcing tool receives the load of the soil cover layer and does not rise, so that the bulb is cut off as a result. Only the ground part can be extracted. This avoids pulling out or pulling down adjacent objects together.

This reinforcing device is thin and flat because it is used between the floor soil layer and the bulb and the covering soil layer, and can be installed on the planting surface of the container to be used. Having. Further, a space 8 where the root of the bulb extends and a space 9 where the water given from above penetrates into the lower floor soil layer are arranged and provided in accordance with the planting style. A reinforcing tool that satisfies this condition can be formed in a lattice or mesh shape by combining thin rod-shaped metal, wood, plastic, or the like. Alternatively, a space for planting in a thin plate-shaped metal, wood, plastic, or the like and a space where water permeates may be appropriately arranged and formed.
It is desirable that the planting space in which the roots extend is larger than the rooting site of the bulb, and that the space where water permeates is located entirely.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION A container for planting a bulb and a lightweight cultivation material are prepared. From the bottom of the container, an appropriate amount of cultivation area is packed as floor soil and leveled, and a reinforcing device is placed thereon, and a bulb is placed on a space for planting the reinforcing device. Then, a cultivation land material is applied as cover soil from above and watered. The irrigated water permeates the floor soil layer from a planting space or a space provided for water to pass through. As the planted bulb grows, the root extends from the planting space of the brace to the lower layer and entangles with the root of the adjacent bulb. Therefore, the bulb is firmly fixed to the reinforcing device by the root portion and the root extended to the floor soil layer.

[0011] When the above-ground portion is taken out together with the bulb at the time of harvesting, the root cannot be passed through this space because the root extends and spreads below the space for planting the reinforcement and is intertwined with the root of another bulb. And since a reinforcement tool receives the load of a soil covering layer, it does not rise by the force which pulls out.
As a result, the root is cut off by the stiffener, preventing the adjacent bulb from being pulled down.

[0012]

Example 1 Example 1 will be described with reference to FIGS. 4 and 5 by taking box cultivation of tulips as an example. FIG. 4 is a perspective sectional view showing the embodiment. FIG. 5 shows a reinforcing device according to the first embodiment. Numeral 2 is a container for placing a cultivation area and planting a bulb. In FIG. 4, 2 is shown as a box without an upper lid, but various shapes are used. First, a reinforcing tool which is formed into a lattice by combining thin rod-shaped members as shown in FIG. 5 is prepared. This is a size corresponding to the surface of the floor soil layer 6 on which tulips are planted. The lattice bone 10 serves as a base for supporting the tulips, and the gap forms a space 8 for planting and water permeability. The cultivation base material is placed as floor soil from the bottom of the container 2 and the surface on which the bulbs are arranged is made substantially flat. The reinforcing tool of FIG. 5 is placed thereon, and bulbs are arranged at appropriate intervals in the space of the lattice. At this time, it is desirable that the root of the bulb does not hit the portion of the lattice that will be the bone. Then, the cultivation land material is applied as covering soil from above. As the planted tulip grows, its roots extend from the lattice space to the floor layer and become intertwined with the adjacent tulip roots. Buds
It extends above the surface and leads to flowering. By the time the above-ground part of the tulip approaches the harvest season and becomes about 40 cm to 50 cm, the roots extending to the floor soil layer are sufficiently entangled with other roots, and even if the above-ground part is shaken by the wind, the bulbs will It is fixed to the reinforcement by the entangled roots of the floor soil layer and supports the above-ground part and does not fall down. Even if the tulip is pulled out at the time of harvesting, the root is entangled with other roots and cultivated land material, so that the root is cut without passing through the gap of the reinforcing device receiving the load of the soil cover. Therefore, the adjacent tulips are not pulled down.

Example 2 Example 2 will be described with reference to FIGS. 4 and 6 by taking box cultivation of tulips as an example. FIG. 6 shows a reinforcing device in which the number of either the vertical or horizontal bars forming the lattice of the reinforcing device of FIG. 5 is reduced. The usage is the same as in Example 1, but with more flexibility in the density at which the bulbs are planted.

Example 3 Example 3 will be described with reference to FIGS. 4 and 7 by taking box cultivation of tulips as an example. FIG. 7 shows a lattice-like bone in the reinforcing device of FIG.
It is formed by providing a space for planting and a space for water permeability. The space where the bulbs are planted is
Desirably, it is larger than the root portion of the bulb and smaller than the maximum lateral cross section of the bulb. In addition, a sufficient number and area of the space where water permeates are secured. The usage is the same as that of the first embodiment, and the effect is superior to that of the reinforcing device of FIG. 5, but the density of planting the bulbs is fixed by the number of spaces for planting the bulbs of the reinforcing device.

[0015]

By using the reinforcing device of the present invention in a box cultivation method, even when a lightweight cultivation base material is used, the bulb aerial part falls down in the middle of growth or an adjacent bulb aerial part during harvesting. Can be almost prevented from falling down. This means that bending due to lodging can be prevented, and the quality of cut flowers is improved. That is, it is possible to utilize a lightweight cultivation base material in the box cultivation method, which greatly contributes to reducing fatigue of the worker and increasing the efficiency of the work.
