Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention is directed to a case where vegetables, fruits, flowers and the like are intensively mechanized and automated like a factory in a greenhouse for high-density cultivation, and a night-cooled seedling in a strawberry seedling raising process. The present invention relates to a hermetically-sealed cultivation apparatus and a cultivation method that are preferably carried out when performing.

[0002]

2. Description of the Related Art In recent years, centralization, mechanization, and automation of agricultural production have been promoted, and the introduction of a work form like a factory has been directed and is becoming widespread (for example, the high-density type described in Japanese Patent Publication No. 2-56048). See cultivating equipment). On the other hand, the adverse effects of pesticides on the human body and the environment are raising serious problems. For example, in greenhouse cultivation, it is inevitable that workers will spray pesticides such as insect repellent into the body or inhale it through the respiratory system at a close distance in a closed room when spraying insect repellent. It is feared that the monthly accumulation will gradually occur as a physical disorder. Currently, the only countermeasures against this are wearing a dust mask and dust-proof clothes.

Similarly, the penetration of a large amount of pesticides into the ground is unavoidable, and in recent years it has been neglected. However, in recent years, the agricultural land around the agricultural land has been rapidly becoming a residential land, and the pesticides that have penetrated into the ground are rapidly growing. Water pollution due to water pollution and environmental deterioration due to changes in the ecosystem environment have been widely pointed out, and there is a strong demand for improvement. A recent example is the demand for prevention of pesticide pollution that is applied to golf courses.

Next, when growing strawberry seedlings, the nighttime temperature is kept at 15 ° C. or lower for a certain period of time to promote flower bud differentiation and the harvesting and shipping period is an expensive demand period. The seedling raising method adjusted from early November to early December (hereinafter referred to as the night cold seedling raising method) is widely practiced. Specifically, a farmer in Shizuoka prefecture is carrying the strawberry seedlings up to the foot of Mt. Fuji and demonstrating the effectiveness of the night cold seedling raising method (mountain raising seedling raising method). In other regions, there is a refrigeration facility where the strawberry seedlings are brought into the refrigeration facility at night and brought out of the refrigeration facility during the day (long-term cold storage method).
Have been implemented.

[0005]

A first object of the present invention is to enhance the effect of spraying pesticides and the like and prevent the worker from scattering to the body and invading the respiratory system, and the crop. It is an object of the present invention to provide a hermetically-sealed cultivation apparatus and a cultivation method which prevent the possibility of soil pollution, water pollution, and environmental pollution of a cultivation place as much as possible.

[0006] Another object of the present invention is to provide a closed-type cultivation apparatus and a cultivation method suitable for carrying out a night-cold raising method for strawberry seedlings. That is, the conventional method for raising seedlings to bring them to the foot of Mt. Fuji is very troublesome, labor-intensive, and labor-intensive. Further, in the case of the method by refrigeration, there is a work of putting the strawberry seedlings in and out of the refrigeration facility, and if this becomes a daily routine, it will continue for about 20 days, which is very cumbersome and labor-intensive. In any case, since the work contents cannot meet the demands of the aging and efficiency (industrialization) of farmers in recent years, it is a problem to be solved.

[Function] A cultivation environment (a crop) is covered with a dome-shaped shield 3 or 13 and is suitable for a plant (cultivation 1) different from a human living environment (for example, carbon dioxide concentration, humidity,
(Temperature) can be artificially and positively produced by a method such as ventilation in the dome-shaped shield, so that good growth and results of the cultivated product 1 can be promoted. By the way, it is already well known that plant plants such as offices are weakened or die in a relatively short period of time due to the difference in living environment from humans.

Since pesticides such as insect repellents are sprayed inside the dome-shaped shield 3 or 30 or 13, the spraying agent may be scattered directly on the body of an outside worker, or There is no direct inhalation of pesticide vapors floating in the air, and it is possible to perform agricultural work in an extremely healthy and good environment, which is hygienic. In addition, when spraying pesticides, the inner volume of the dome-shaped shield 3 or 30 or 13 is reduced as much as possible, so the spray amount of pesticides is greatly saved from the viewpoint of spray concentration. do it,
Moreover, a sufficient medicinal effect can be expected.

The work can be performed by opening the dome-shaped shield 3 as required for the care and harvest of the cultivated product 1. Of the pesticides sprayed by the spraying mechanism 4 or 12 or 14 inside the dome-shaped shield 3, the excess liquid that has dropped onto the cultivation floor 2 as a droplet is collected in a gutter 15 and collected in a specific container. However, it will not penetrate into the ground or otherwise be discarded (Fig. 4).

When cold air of about 10 ° C. is supplied into the room of the dome-shaped shield 3 through the cold air pipe 73 at night, the room of the dome-shaped shield 3 is kept in a room temperature at the same temperature.
When the same cooling condition is continuously repeated for about 20 days at night, the effectiveness of night-cooled seedlings can be obtained for the strawberry seedlings 72 grown in the same room. In this case, the heat insulation effect of the heat insulating material 70 laid on the cultivation floor portion can improve the cooling efficiency. Further, when the inner volume (air volume) of the dome-shaped shield 3 is reduced as much as possible during cooling at night, the cooling load is significantly reduced by that amount, the thermal efficiency is improved, and the rating (capacity) of the cold air supply mechanism 74 is increased. Can be lowered.

EXAMPLE An example of the present invention shown in the drawings will be described below.
The closed type cultivating apparatus shown in FIG. 1 is premised on, for example, a cultivating stand 20 having a skeleton assembled with a resin-coated steel pipe and a joint, and is placed on the cultivating floor 2 on the upper surface of the cultivating stand 20, for example, a potted cultivated product 1 A structure in which the upper part of the cultivation floor 2, which is supposed to be cultivated by orderly placing a large number of plants, is hermetically covered with a dome-shaped shield 3 having a size and shape that does not hinder the growth of each cultivated product 1. It is said that. The cultivating table 20 is in a greenhouse.
Or, it is constructed by being fixed on the open ground without greenhouses and other buildings. Depending on the case, it is also possible to implement the cultivation device disclosed in Japanese Examined Patent Publication No. 2-56048 with a configuration capable of moving on a track laid on the ground. The height of the cultivating floor 2 of the cultivating table 20 is set to a height at which a worker does not have to work in a cramped posture with a bent waist, for example, a height of about 1 m on the ground. The width of the cultivating floor 2 is such that a worker standing on both sides of the cultivating table 20 can reach all the cultivated products 1 placed on the cultivating floor 2 and perform sufficient maintenance, for example, 11
The size is about 0 to 120 cm. The length of the cultivation table 20 is usually the full length of the greenhouse or the site, or is a length obtained by dividing the length into several parts.

As shown in the main part of FIG. 3, the cultivating floor 2 has a floor plate material having a thickness of about 2 to 5 mm extruded from a synthetic resin and laid on the upper surface of the cultivating table 20 to make the seam watertight. Alternatively, it is formed by being joined to a water blocking structure. At one side edge or both side edges of the cultivation floor 2, as shown in FIG. 3, groove-shaped gutters 15 integrally formed with the floor plate material are provided over the entire length in the longitudinal direction. This gutter 15 has a groove width of 50.
mm, the depth of about 30 mm, for collecting or concentrating collectively in one place when a chemical solution such as irrigation or insect repellent to the cultivated product 1 is dropped on the cultivated floor 2. It is a thing. Therefore, the cultivation floor 2 is inclined (one-sided inclination or both-sided inclination) in the width direction toward the gutter 15 at the edge thereof with an appropriate flowing water gradient.

The dome-shaped shield 3 has an airtight structure in which a shielding film 6 such as a vinyl sheet is provided on the outer surface of the arch-shaped frame 5 supported by the cultivating platform aggregates 21 (FIG. 2) on both sides of the cultivating floor 2. Is stretched to form a dome shape having a substantially uniform cross section in the longitudinal direction of the cultivation table 20. Arched frame 5 of FIG.
Is formed into a flat, semi-cylindrical arch having a height (size) that does not hinder the growth of the cultivated product 1 placed on the cultivating floor 2, and both ends thereof are lifted and lowered as detailed in FIG. It is attached to and supported by the cultivating platform aggregate 21 by the supporting portion 7 of a possible mechanism. The support part 7 of FIG. 2 is composed of two clamps 23 that can raise and lower the arched frame 5 by tightening and loosening the bolts 22 and fix the arched frame 5 at a desired height position. Of course, the supporting portion 7 can also be implemented by means of mechanically raising and lowering by a known rack and pinion mechanism, a hydraulic (or pneumatic) cylinder mechanism, a link mechanism, or the like. By positioning and fixing the arch-shaped frame 5 as high as possible by the support portion 7, the dome-shaped shield 3
Is in a large volume state that promotes growth of the cultivated product 1. Conversely, by lowering the arch-shaped frame 5 as low as possible, a small volume is obtained, so that the structure is basically a variable volume type.

A shield film 6 stretched over the arch frame 5
For example, as shown in FIG. 3, the shielding film 6 is formed on the sheet fastening rib 25 having a spherical cross section formed on the edge portion of the floor plate 2.
The sheet holding cover 26 having a C-shaped cross section, which is also extruded and molded with a synthetic resin, is put on the both side edge portions of the sheet and is detachably fixed. Thus, the inside of the airtightly sealed dome-shaped shield 3 can easily create an optimum environment for plant growth by artificially adjusting the carbon dioxide concentration, temperature and humidity by ventilation or other methods (for example, FIG. 9
reference). As the fastening means of the shielding film 6, for example, a known sheet stopper disclosed in FIG. 1 of Japanese Utility Model Publication No. 57-44093 can be applied. Therefore, when it is necessary to care for the cultivated product 1, the sheet holding cover 26 is removed to unfasten the shield 6, and the shield film 6 is opened by rolling up the so-called dome hem. Alternatively, instead of attaching and detaching the fastening means, an openable / closable portion 60 (see FIG. 9) such as a synthetic resin zipper, a magic tape, or an eyelet (hook) is provided at an appropriate place of the shielding film 6, and the portion 60 is opened. It can also be carried out in a configuration for performing maintenance work.

Inside the dome-shaped shield 3, a spray pipe 4 arranged in the longitudinal direction of the cultivating floor 2 and supported on the cultivating floor 2 by struts 29 is used for irrigation or insect repellents, other agricultural chemicals, liquid fertilizers, etc. It is installed as a spraying mechanism. The spraying pipe 4 is provided with a large number of spraying nozzles 4a directed downward or obliquely downward at a pitch of about 10 to 30 cm in the longitudinal direction.
Therefore, a irrigation pump can be used for irrigation and a hose of a sprayer can be connected to the spray pipe 4 for spraying insect repellents, etc., and spraying can be performed in a closed chamber partitioned by the dome-shaped shield 3. . When spraying insect repellents, the arch-shaped skeleton 5 of the dome-shaped shield 3 is lowered as indicated by the chain double-dashed line to the extent that the dome-shaped shield 3 does not interfere with the crop 1. By lowering the volume to a small volume, and by spraying a small amount of insect repellent, the concentration of insect repellent in the dome can be increased, and the effectiveness of its medicinal effect can be shown to reduce the cost and the amount of pesticide used. Of course, since the insect repellents are sprayed in the dome-shaped shield 3 which is hermetically sealed, there is no possibility that the insect repellents will splash on the body of the worker outside the dome or be inhaled into the body from the respiratory system. is there.

Of the pesticides such as insect repellents sprayed through the spray pipe 4, the excess liquid dropped onto the cultivation floor 2 is the gutter 1
5, it is made to flow in a fixed direction, and as shown in FIG. 4, all is collected in the collection tank 50 to prevent environmental pollution. The pesticides collected in the collection tank 50 are sent to the spray pipe 4 again by the circulation pump 51 to be used efficiently. Collection tank 50
The spare tank 50 'is also prepared if necessary.

[Second Embodiment] The cultivation apparatus shown in FIG.
(And the cultivation table 20) a work cart 9 which is freely movable in the longitudinal direction.
Is installed, and the dome-shaped shield 30 is provided on the work carriage 9. The cultivating floor 2 has a structure in which a synthetic resin floor plate material is laid on the upper surface of the cultivating table 20 in a watertight or water-tight structure, as in the first embodiment.
As shown in FIG. 6, a gutter 15 continuous in the longitudinal direction of the cultivation floor 2 is formed on both edges (or one edge may be used) (FIG. 5). The outer edge of the gutter 15 is a rail 8 having a semicircular cross section, which is placed on the horizontal vertical rail 27 of the cultivation table 20.
Also, it is configured to be formed in series over the entire length of the cultivation floor 2 in the longitudinal direction, and the wheels 31 of the work carriage 9 run on it (FIG. 7). However, as shown in FIG. 8, the gutter 15 can also be implemented with a configuration in which only one gutter 15 is provided at the center of the cultivation floor 2. In this case, the cultivation floor 2 is formed on both inclined surfaces that descend toward the central gutter 15.

The skeleton of the work trolley 9 and the dome-shaped frame 10 thereon are assembled by a resin-coated metal tube and a synthetic resin joint, and the outer surface of the dome-shaped frame 10 is covered with a shielding film such as a vinyl sheet. 11 is stretched so that the lower surface is opened. The side surfaces on both sides in the width direction of the cultivation floor 2 of the shielding film 11 are fixed to the skeleton of the work carriage 9 in a state of being hung down to a position directly above the rail 8, and both side surfaces before and after the traveling direction are on the cultivation floor 2. It is fastened in a state in which it is rolled up to a height position where the upper part of the placed cultivated product 1 is slightly touched. The dome-shaped frame 10 is configured so that the height of the skeleton of the work carriage 9 can be adjusted by, for example, a supporting portion 7 or means of a mechanism capable of moving up and down similar to that described in the first embodiment. Therefore, the height of the dome-shaped shield 30 can be adjusted to the height of the cultivated product 1.

Inside the dome-shaped shield 30, an arrangement (higher than the cultivation floor 2) that does not interfere with the growth or growth state (standing state) of the cultivation 1 placed on the cultivation floor 2 is provided. The spray pipe 12 for insect repellent or the like is installed as a spraying mechanism in the shape (position) and the shape. Therefore, a sprayer (or irrigation pump) mounted on the work carriage 9 or installed in another place
Is connected to the spray pipe 12 and the work carriage 9 is appropriately moved forward while spraying insect repellents and the like to minimize the amount of chemicals required in the space within the dome-shaped shield 30 that is small and limited. The maximum medicinal effect can be expected in the amount. Of course, there is no fear that the sprayed insect repellent or the like directly splashes on the body of a worker nearby or is suspended in the air and inhaled. Excess liquid of insect repellent or the like sprayed toward the cultivated product 1 is dropped onto the cultivating floor 2 and received by the gutter 15 and is intensively collected at a predetermined place in the same manner as shown in FIG.

[Third Embodiment] FIG. 9 shows an embodiment in which the closed-type cultivating apparatus shown in FIG. 1 is modified into a structure capable of carrying out the night-cold raising method for strawberry seedlings. The basic structure of this cultivation device is basically the same as that of the embodiment shown in FIG. A heat insulation material 71 such as urethane foam is closely laid on the cultivation table 20 to form a cultivation floor, and the strawberry seedlings 72 planted in the pot 71 are housed and grown together with the pot 71. The dome-shaped shield 3 covering the upper part of the cultivation floor is supported on the cultivation table 20 by the supporting portions 7 of the mechanism in which both ends of the arch-shaped framework 5 can be moved up and down, and the arch-shaped framework 5 is covered with a vinyl sheet or the like. The membrane 6 is stretched in an airtight structure. By lowering the arch-shaped frame 5 as much as possible, the internal volume (air volume) of the dome-shaped shield 3 in the room can be reduced to a fraction.
A cold air tube 73 is installed in a shape attached to the arch-shaped frame 5 toward the ridge of the ceiling of the dome-shaped shield 3 in the room. To this cold air pipe 73, a cold air pipe 75 is connected from a cool air supply mechanism 74 having a configuration including a cooler and its control device, a cold air pressure, a flow rate control system, and the like. Further, in the longitudinal direction of the cold air pipe 73, a plurality of cold air outlets 76 ... Is provided at a pitch of, for example, about 20 to 40 cm, and cold air of about 10 ° C. is blown toward the room from the air outlets 76. Is cooled to about 15 ° C. or lower, preferably about 10 ° C. In order to equalize the amount of cold air blown into the room and the room temperature, the cool air outlet 76 located at a position close to the connection point of the cold air conduit 75 has a small diameter, and the adjusting means increases the diameter as the distance increases.

On the other hand, one or a plurality of exhaust ports facing the interior of the dome-shaped shield 3 are provided, and the exhaust conduit 77 connected to the exhaust port is connected to the suction side of the cold air supply mechanism 74, thus forming a closed circulation circuit for cooling. Therefore, the thermal efficiency is improved. If necessary, a temperature sensor is installed in the room, and automatic control is performed to feedback control the cold air supply mechanism 74 based on the detection signal.

Therefore, in the case of performing night-cold growth of the strawberry seedlings 72 with the closed type cultivation apparatus having the above-described structure, first, the dome-shaped shield 3 is lowered as much as possible to make the room volume (air volume).
To reduce. Then, at night, the cold air supply mechanism 74 is operated to cool the interior of the dome-shaped shield 3 to about 10 ° C. Then, during the daytime, when the cooling is stopped and the strawberry seedlings 72 are exposed to sunlight for about 20 consecutive days, the night cold seedling raising method is effective and the strawberry harvest time is adjusted.

The same chilled seedling raising method for strawberry seedlings is carried out by means of replacing the blower 40 with a cold air supply mechanism in the closed type cultivation apparatus of the embodiment shown in FIG. 9 or separately shown in FIG. As described above, the cooling air pipe 73, the cold air supply mechanism 74, and the closed cooling circuit connected to the exhaust port by the exhaust pipe are provided, and in particular, as shown in FIG.
It is also possible to carry out the cooling in the state where the indoor volume of is reduced and to carry out the night cold air seedling method.
