Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a plant container in a night-cooling device for plants, which produces fruits, etc. at a desired season by artificially adjusting the differentiation of flower buds of plants. It is related to.

Conventional technology A night cooling device for plants that artificially adjusts the differentiation of flower buds by controlling day length and night temperature is disclosed in Japanese Patent Application Laid-open Nos. 88822-1982 and 98925-1981. It is known from publications etc.

The above-mentioned night cooling system installs a refrigerator inside the greenhouse, stores the plants to be regulated in the greenhouse at night and cools them at a predetermined temperature, and leaves the plants to be regulated outdoors for a predetermined time during the day. This method artificially ELIi differentiates the flower buds of plants by exposing them to sunlight, and in this method, a mobile bench is used to place the plants to be adjusted.

Problems to be Solved by the Invention However, since the above-mentioned mobile benches adopt a three-tiered shelf type or a stacking type of three units formed in different sizes, all the adjustable benches are To expose plants to sunlight, place them on other benches (if you have a 3-tiered shelf type), or break up large and small benches and spread them out on the ground (
In the case of the overlapping method), it is necessary to return the materials to the original polymerized state when storing them in the greenhouse, which is troublesome and requires a lot of labor and time.

Means for Solving the Problems Therefore, the present invention provides a night cooling device for plants that artificially adjusts the differentiation of flower buds of plants by controlling the day length and night temperature, and provides a trolley for storing plants to be adjusted. The above-mentioned problem is solved by providing a truck with a plurality of tiers of plant mounting shelves, each of which can be expanded and stored in different directions.

Plants to be adjusted, planted in pots or seedling boxes, are placed on each plant shelf on a trolley to adjust day length and night cooling.

To cool the conditioned plants at night, each aW with the conditioned plants
One shelf is housed in a building in multiple stages on a trolley,
The cooling system installed in the building is activated to blow cool air at a predetermined temperature onto the plants. During the day, the cart is moved outdoors with the plants stored on each shelf a, and each shelf is expanded outward to expose each plant to sunlight for a predetermined period of time to promote photosynthesis. After that, each shelf is returned to its original storage state, and the cart is housed indoors, where it is cooled again at night.

This process is repeated to artificially adjust the differentiation of flower buds in plants.

Embodiment The structure of the present invention will be explained with reference to an embodiment shown in the drawings. 1 is a building with a night cooling system that has been insulated over almost the entire surface including the roof 1a, the eave height tb, and the door 1c;
The room has a light-shielding structure so that the day length can be adjusted, and when all the doors 1c are closed, it becomes a dark room. 2
is the temperature [1 is a possible air-conditioning device, 3 is an outdoor unit, and the air (cold air) cooled by the air-conditioning device 2 during night cooling passes through multiple ducts 4 installed on the ceiling indoors to the bottom of the duct. The cool air is blown downward from the provided cold air outlet 4a to cool the room. The air conditioning system M2 has a control mechanism to constantly maintain the room temperature at a predetermined temperature depending on the type of the plant a to be regulated, the shipping time, etc.

Note that the duct 4 does not necessarily need to be an expensive iron pipe, and may be an inexpensive pipe made of vinyl or vinyl chloride.The building 1 may be an existing greenhouse, such as a real seedling growing house, equipped with an air-conditioning device 2, etc. At the same time, the existing greenhouse can be used as a night cooling device by installing black curtains or the like inside, so it can be used effectively throughout the year.

Reference numeral 5 denotes a night cooling trolley for storing plants (for example, strawberries, etc.) a, which has a fixed top plate 5a and movable casters 6, so that it can be easily moved inside and outside the building l by hand. It has become. Moreover, a plurality of plant mounting shelves 7 are attached to the trolley 5 below the top plate 5a so as to be expandable and retractable in different directions. In the case shown in FIGS. 2 to 4, each plant mounting shelf 7 is slidable on a rectangular cart 5 in a plan view via a guide rail 8 so that each plant shelf 7 can be pulled out outward in a cross direction. A stopper 9 is provided on the side of the cart 5 and a stopper receiver 10 is provided on the side of the shelf 7 to ensure safety so that the shelf 7 does not fall from the cart 5.

Further, the top plate 5a of the trolley 5 and the bottom plate 7a of the mounting shelf 7 are made of wire mesh, punched plates, etc. to improve air permeability and drainage.

In the system shown in FIG. 5, a plurality of shelves 7° are mounted on a cart 5' so that they can rotate outwardly around eccentric shafts 11, and 7°a is The top plate 12 is a stopper. The one shown in Fig. 6 is a combination of a pull-out type shelf 7 and a rotary type shelf 7°, and the storage surface for plants a has nine levels including the cart top plate 5a. Shelf 7.7°
12a is a rotation fulcrum. In FIG. 7, reference numeral 13 denotes an irrigation system installed in an outdoor vestibule close to building 1, which uses a pump 15 equipped with a timer 14 to suck water from a water supply source 16 such as a water storage tank and sends water to an irrigation pipe 17.
The plant a on the trolley 5, which has been moved to the front garden, can be watered from the spray nozzle 18 for an hour as needed by opening the aM shelf 7.

In the above configuration, the plants a to be adjusted planted in pots, seedling boxes, etc. are placed on the top plate 5a of the trolley 5 and each plant shelf 7, and stored in the building 1 as shown in FIG. When planting plants in the trolley 5 that is housed and cooled at night, the trolley 5 can be moved to an appropriate location for loading, etc. Moreover, each loading shelf 7 is shown in FIG. If you carry out the work with the shelves unfolded in all four directions, and then push the loading shelves 7 in after loading, the loading shelves 7 will be guided by the guide rails 8 and smoothly stored inside the trolley 5. Plant a can be taken in and out quickly and easily.

In addition, since the plants a can be stacked three-dimensionally on the trolley 5 in five stages (the one shown in Fig. 6 is nine stages) including the top plate 5a and the shelf 7, the trolley 5 itself is small. Even with the surface area, a large amount of plants a can be stored. Therefore, it is possible to increase the amount of plants accommodated per floor unit area of the building 1, so that the heat calories consumed during cooling are reduced per plant, and costs are reduced accordingly. Moreover,
Since the plants a are arranged in a cross shape on the front, rear, left and right sides of the trolley 5, the front and rear and left and right balances are maintained well even when deployed, and the stability of the trolley 5 is ensured.

A large number of trolleys 5 with the plants to be trimmed a stored in multiple stages as described above are housed in the building 1, and the air-conditioning device 2 installed in the building 1 is operated to the cooling side to blow cold air at a predetermined temperature to the plants. guess During the day, the trolley 5 is moved to the front garden with the plants a placed and stored on each shelf 7, and each shelf 7 is expanded outward to allow sunlight to shine through each shelf for a predetermined period of time. The plants a are placed in a cross shape on the front, back, left and right sides of the trolley 5 when the mounting shelf 7 is unfolded, so that the balance during unfolding is maintained well and the sunlight evenly hits each plant a. This is extremely convenient. Incidentally, since the planting of shrubs during the day is automatically carried out by the timer 14 of the shrub installation @ 13, labor saving can be achieved. After irradiation with sunlight for a predetermined period of time, each shelf 7 is returned to its original storage state, and the trolley 5 is housed indoors and cooled again at night.This is repeated to artificially adjust the differentiation of flower buds of plant a. It is something.

In addition, in the above-mentioned present example, the plant a housed in the building l
Although we have described a method in which cold air is applied to the plants at night, night temperatures may also be controlled by applying warm air depending on the type of plant a and the season of harvest.

Effects of the Invention As described above, the present invention provides a night cooling device for plants in which the differentiation of flower buds of plants is artificially adjusted by controlling day length and night temperature. Since the trolley is equipped with a plurality of tiers of plant storage shelves that can be expanded and stored in different directions, a large amount of plants can be stored on the trolley even if the trolley itself has a small surface area. This allows for fewer thermal calories per plant during cooling, which makes it possible to reduce costs accordingly. Moreover, during the day, each plant shelf is unfolded in a different direction and exposed to sunlight, which not only maintains a good balance of the cart, but also allows each plant to be evenly exposed to sunlight. Irrigation can also be carried out efficiently, further promoting flower bud differentiation. In addition, since plants can be quickly and easily taken in and out of the trolley, labor is reduced and workability is greatly improved.
