The nutrient solution cultivation method that is the first conventional technique is expensive because copper and brass are used, but the copper and brass are limited to a considerable amount of nutrient solution required for cultivation. There is a limit to sterilization because it only contacts for a time. Moreover, since the area of the mat or the like is considerably large, once a disease occurs in a certain strain, the disease may spread to many strains.

Furthermore, the second conventional technique includes a hot water pipe of a different system from the irrigation system in which the plant cultivation apparatus imparts heat to the soil in the planter, so that both initial and running costs increase. Become. Also, the synthetic resin planter has an opening that is open so that the hot water pipe can be continuously exposed along a predetermined direction in the approximate center of the bottom of the main body, and the main body side wall through which the hot water pipe passes. However, since the cutout portion is formed so as to allow the hot water pipe to pass therethrough, it is not easy to ensure the strength of the synthetic resin planter body. Furthermore, because the planter's capacity is limited, even if a plant cultivated in a planter is affected, its spread is suppressed, but the planter is installed continuously with its long axis as the cocoon direction. Therefore, the soil is filled up to a portion that is not indispensable for the growth of the plant.

Therefore, the present invention was devised in order to solve the above-mentioned problems, and a cultivation container capable of preventing the spread of diseases occurring in cultivated plants with simple means and improving the use efficiency of cultivation soil. It is intended to provide.

In FIG. 1, 50 is a display / input device, 52 is a simple mobile phone, and 53 is a portable information terminal. The grower usually performs input for setting the cultivation conditions from the input / output unit 50, but in this system configuration example, input can be performed from the place away from the farm server 51 by the above-described portable information terminal or the like. , The convenience of system management can be improved.

The cultivation container of the present invention is suitably applied to the cultivation system. FIG. 2 is a perspective view showing a state in which the cultivation container 56 filled with the cultivation soil 57 is placed on the cultivation bed 55 made of foamed synthetic resin such as polystyrene foam supported by the support device 54. 58 is a liquid supply dripper that branches from the irrigation tube 34 and supplies the nutrient solution to each cultivation container 56 individually. The liquid supply dripper 58 is configured to be able to supply liquid from two places in the front and rear with respect to one cultivation container. In this embodiment, the support device 54 adopts a hanging type, but may be a type standing on a greenhouse floor.

As shown in an enlarged view in FIG. 3, the cultivation container 56 is manufactured by deep-drawing by press molding at a temperature of about 150 degrees after a non-binder nonwoven fabric of polyester long fibers is framed. The material nonwoven fabric has a thickness of 0.53 mm, a tensile strength length of 380, a width of 200 (N / 5 cm width), a breaking elongation length of 140, a width of 120%, a tensile strength length of 20.0 (N), and a heat shrinkable length and width. 0, air permeability (CC / cm2 / S) 30 (manufactured by Asahi Kasei) was used. This cultivation container is suitable as a cultivation container because it has rigidity and excellent shape retention, and has appropriate air permeability and water permeability.

Hereinafter, an example of cultivating tomatoes in the greenhouse shown in FIG. 1 will be described. With reference to FIG. 2, this cultivation container 56 is mounted on a cultivation bed 55 made of a foamed resin container continuously supported by the support device 54 with the long direction facing the cocoon direction at an appropriate interval. Is placed. This interval is adjusted so that the trunk density of the plant has a cultivation density capable of growing healthy without competing with the adjacent plant. In the example of tomato, if it is specifically set to the same extent as the width dimension of the cultivation container 56, there is no problem in cultivation.

The dimensions of the cultivation soil container of the cultivation container 56 are 90 mm wide, 200 mm deep, and 110 mm deep. The dimension of the bottom is about 10 mm smaller than the above dimension. In addition, what is necessary is just to make it adapt to the size of the existing cultivation bed about a depth dimension. This cultivation container 56 is filled with culture soil 57. Since the flange of the cultivation container 56 exists in the area | region which is not drawn, it has the thickness and rigidity of material itself. The front and rear flanges of the cultivation container are placed on the upper end of the side wall of the cultivation bed. Regarding the number of plants to be planted in each cultivation container, in this example, one tomato is planted and two harvesting trees are standing. Of course, it is good also as two planting. In short, the length in the cocoon direction of the cultivation container, that is, the width dimension only needs to be set to an indispensable length for the growth of the root of one plant, and in the example of tomato, about 90 mm is preferable. Moreover, the space | interval of each cultivation container should just be set so that the space | interval which can be cultivated with the cultivation density in which the trunk of a plant can grow without excess and deficiency in the cocoon direction should be ensured.

Even if a tomato that is growing in a certain cultivation container becomes ill while cultivating a plant in such an environment, only the plant in the cultivation container is damaged, and the plants in other cultivation containers are damaged. It is possible to prevent the spread of illness through the medium. In addition, the amount of medium used can be halved, and material costs can be reduced.

Although the cultivation container of this example can also grow strawberries, any crop can be cultivated as long as it is hydroponically cultivated in a greenhouse. Of course, in that case, it is necessary to set the dimensions of the cultivation container and the interval for each container to the optimum values for each crop.
