Description

[Detailed description of the invention] Industrial field of application This invention relates to a heating and cooling device for raising seedlings in a facility in greenhouse horticulture.

Conventional technology and its problems In conventional greenhouse horticulture, a separate tunnel is installed within the facility to keep the seedling bed and cultivation bed warm, in part or in its entirety. It is common practice to maintain heat and create a suitable environment for crops, but in recent years, as artificial cultivation on the ground has become more popular, it has become difficult to maintain a suitable environment in ordinary tunnel facilities. Ta. That is, there were problems such as insufficient heat insulation of the artificial culture medium and the cubes provided thereon, and that the direct sunlight was too strong in the summer. Therefore, in order to solve these difficulties, the inventor of the present invention has solved the problems by the present invention as a result of various tests and researches.

Problems that the invention aims to solve In order to install an artificial culture medium in a facility, a cultivation bed 2 is set up in an appropriate location within the facility, and then polyethylene or PVC film, etc. Since the artificial culture medium made of such as There was a problem that required a lot of effort to manage. Moreover, in that case, it was difficult to provide a temperature environment suitable for the artificial medium.

Therefore, in the present invention, a simple framework is constructed within the facility, a duct is installed in this framework, and the framework is covered with a heat insulating film and a light shielding material in the summer.

By the way, with a conventional tunnel seedling raising device, when the seedlings inside the tunnel grow and grow larger, the tunnel is too narrow, so the tunnel is removed to allow continued growth, but the outside temperature still remains. If the temperature is too low or too high for summer seedling raising, the young parts of the seedlings will not be able to adapt to the outside temperature and may not be able to enter the tunnel, so this is the problem and there is no solution. Issues are raised.

Embodiment of Means for Solving the Problem As a means for solving this problem, a facility illustrated as an example will be described in detail.

An appropriate number of cultivation beds 2 are provided at appropriate positions in a normal facility 1 such as a glass room or a vinyl greenhouse,
This is coated with a thin film F of vinyl, polyethylene, etc. such as a white or black integral film, and an artificial medium bed 7 made of rock wool, peat moss, vermiyukilite, etc. is placed above it, and this is placed on both sides of the longitudinal direction. In-house covering support 3 covering
are provided, and the above-mentioned coated support 3 is provided on the sides and above these.
A supporting body 4 made of binding rope or PVC is connected, and a heat insulating film 5,
During high temperatures such as in the summer, a light shielding body 6 (for example, an aluminum vapor-deposited film, a black light shielding net, etc.) is covered, and a heat insulation duct or a cooling duct D is arranged on both sides or one side of the artificial culture medium bed 7 within the covering body. Set up

Therefore, the upper part of the heat insulating or cooling covering body, that is, the heat insulating film 5 or the light shielding body 6 is designed to form a space in which the crops can flourish in the facility 1 when they grow and elongate. A gap is provided so that it can extend into the outside facility, and appropriate devices (clips, etc.) C, C for holding the heat insulating film 5 or the light shielding body 6 at appropriate places are attached.

In addition, in the above case, the heat insulating or cooling covering is placed on the support of the nursery bed from both sides in the longitudinal direction of the facility in a door shape, and an elongation gap is provided here for the elongated part of the plant body. However, in some cases, a window-like gap is provided above the covering film, through which the growing part of the seedling can be exposed.

In the drawing, reference numerals 8 and 8 are cubes serving as pots for sowing and raising seedlings, and the artificial medium bed 7 and the cube 8 are covered with a covering material such as polyfilm.
9, 9 is a liquid supply pipe for water supply or liquid fertilizer.

In addition, there are heat insulation or cooling ducts in Facility 1.
D' is placed in an appropriate number and at an appropriate position. P represents a crop.

Effects and Effects of the Invention The present invention, with the above-mentioned configuration, allows seeds to be sown or transplanted into an artificial medium bed 7 made of rock wool or the like placed on a cultivation bed 2 provided at an appropriate location in the facility 1, and into a cube 8 provided as necessary. When it is cold, heat insulating film 5 is placed on the crops in the greenhouse covering support 3,
During high temperatures such as summer, a light shielding body 6 is covered and water and liquid fertilizer are supplied from the liquid supply pipes 9, 9 and crops are cultivated. ) Since ducts D and D were installed,
It can maintain the artificial medium and the cubes placed on it at the appropriate temperature, promoting germination, seedling raising, and cultivation. It can also directly keep warm and cool the artificial medium, which has a smaller volume than the facility itself, and is highly effective with low energy consumption. When large crops can be cultivated and the crops have grown and flourished in the facility 1, this part can be extended into the facility 1 through the gap between the upper clips of the covering body above the support frame 3. It serves as a support for the crops, and a support can be inserted into it to support the crops. It can be adapted to the cultivation of fruit vegetables (tomatoes, cucumbers, melons, etc.) and fruit trees, and even in that case, the inside of the facility can be kept warm by the duct D′, which is not possible with conventional small tunnel coverings inside the facility. In addition, especially in cultivation using artificial culture media, an appropriate temperature environment can be obtained with less energy and with simpler equipment (i.e., facility covering 3 and its connecting ropes or supports 4) compared to conventional hot water heating. This method has the advantage that better effects can be obtained by raising and cultivating seedlings using an artificial medium, and the equipment is simple and economical.

Claims (1)

[Scope of utility model registration request] A seedling bed of appropriate size and number and a film support are provided above it in a plant cultivation facility, and a heat-insulating and light-shielding film is placed over the film support in the longitudinal direction. This is an in-facility seedling raising device that has gaps and heat insulation and cooling ducts installed inside and outside of these seedling beds so that they can grow further into the facility.
