Description

Specification

Super forcing cultivation system

Technical field

[0001] The present invention relates to a super-forcible cultivation system for cultivated plants, and in particular, for seasonally cultivated plants such as strawberries, the temperature and soil temperature are locally controlled to efficiently perform multiple harvesting throughout the year. It is related to the super-forcing cultivation system that makes it possible.

Background art

[0002] The cultivated plants were all seasonal in nature. The widespread use of greenhouses and greenhouses enabled growth and harvesting throughout the year.

However, in the greenhouse, most of the energy poured into the temperature control is generally dissipated in the surrounding space, so a great deal of energy is wasted, whereas in the greenhouse, the temperature control is not always sufficient. .

[0003] Heat pipes are often used for these problems.

This is because if the heat pipe is laid, the temperature and soil temperature in the vicinity of the plant can be adjusted locally, and a great deal of energy is not wasted.

Conventionally, as a heat pipe, a single pipe type that forcibly circulates the heat medium (hot water or cold water) for one end of one pipe and adjusts the temperature of the air or soil around the pipe wall by heat conduction is the mainstream. However, a temperature gradient occurred along the length of the tube, making it difficult to adjust the temperature Z soil temperature uniformly.

[0004] Therefore, recently, a double pipe that also has an inner pipe / outer pipe force has been provided, and after removing air into the gap between the inner pipe and the outer pipe, the working fluid is sealed and the heat medium is forced into the inner pipe. A double-tube system is being used, which circulates in the air and emits far-infrared rays from the outer wall of the outer tube by vaporizing the Z fluid and adjusting the ambient temperature Z soil temperature by radiation.

Compared with the single tube type, the double tube type can control the temperature uniformly in the longitudinal direction of the tube, and the force can be efficiently controlled only in the vicinity of the tube.

For example, in Patent Literature 1, in house cultivation, a double-pipe heat pipe is embedded in the culture soil of a seedbed container, and a high-temperature heat medium is circulated in advance to perform heat sterilization of the culture soil. A technique for adjusting the soil temperature during the cultivation period is disclosed.

[0005] Patent Document 1: Japanese Unexamined Patent Publication No. 2003-000071

[0006] However, when growing cultivated plants such as strawberries, subtle temperature control is required. For example, prior to the main planting of seedlings, the seedlings are cooled by exposure to the night air (night cooling), and then cultured soil. After planting the plant, it is necessary to cool and warm at least the part called “crown” of the seedling to promote the differentiation of the flower buds, and after ripening it is necessary to blow at least cold air to the fruits in order to improve the sugar content.

In particular, in the case of long-day varieties or seasonal varieties of forced multiple cultivating throughout the year, the workability is extremely poor for carrying in / out / installation during night cooling, cooling / heating, and air blowing!ヽ Work is required, but the tolerances of the set temperature and set time are severe, so it is difficult to manage the temperature efficiently and economically.

Brief Description of Drawings

FIG. 1 is an explanatory diagram of super-forcing cultivation systems according to first to fifth examples.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments and effects according to the present invention will be specifically described with reference to the drawings. FIG. 1 is an explanatory diagram of the super-forced cultivation system according to the first to fifth examples.

Example 1

[0020] The two seedbed containers 1 and 11 each contain the culture soil 2, and the seedlings 3 and 3 of the cultivated plants are planted in two rows in the culture soil 2 of the seedbed container.

The first heat pipes 5 and 51 are installed in the nursery containers 1 and 11, respectively. The first heat pipes 5 and 51 are in the middle of the two rows of seedlings 3 and 3, and are described in this example, at positions close to and above the culture soil, respectively. In the case of V, it is usually installed at the same position.

A second heat pipe 6 is installed between the seedbed containers 1 and 11.

A drainage pipe 4 is provided at the center of the bottom of the seedbed containers 1 and 11, and the pipe wall of the drainage pipe is appropriately provided with pores to discharge excess moisture in the culture soil.

[0021] Each of the first heat pipes 5 (51) includes a coaxial inner pipe 5a (51a) and an outer pipe 5b (51b) disposed substantially horizontally, and between the outer pipe and the inner pipe. After the space is evacuated, a working fluid (not shown) is sealed, and one end force of the inner tube is directed to the other end (i.e., in a direction perpendicular to the paper surface in the figure). When water at a constant temperature is forcibly sent, the working fluid vaporizes and collides with the inner surface of the outer tube. As a result, infrared rays are emitted or absorbed from the outer surface of the outer tube, and the seedling 3 and the vicinity of the seedling Adjust the temperature of the culture soil 2.

[0022] The second heat pipe 6 is similarly provided with a coaxial inner pipe 6a and an outer pipe 6b which are placed substantially horizontally, and the space between the outer pipe 6b and the inner pipe 6a is evacuated. The hydraulic fluid (not shown) is sealed, and the outer tube 6b is a third tube 6c having a plurality of openings in the tube wall (in this case, the broken line represents an opening in the tube wall, not a hidden line) When the air is forcibly sent toward the other end in the space between the outer pipe 6b and the third pipe 6c, as in the case of the first heat pipe, the outer pipe The air conditioned by infrared rays emitted from the outer surface of 6b is radiated from the opening force of the tube wall of the third tube 6c to adjust the temperature around the seedlings 3 and 3.

[0023] As described above, the temperature control power can be accurately executed locally for the minimum necessary time for the minimum necessary portion of the cultivated plant, and the power can be efficiently executed without dissipating wasted energy. For the first time, super-forcing multiple cultivation of cultivated plants throughout the year becomes possible. Example 2

[0024] The seedbed containers 1 and 11 are installed together with the second heat pipe 6 on a support base 9 covered with a first heat insulating sheet 8.

Since the support base 9 is mounted on the fixed base 19 via the wheels 18 and 18, it can move with respect to the fixed base, and an operator stands between the fixed base 19 and the adjacent fixed base 191. By pressing the support base 9 with a lateral force in the figure, the work path reaching the upper side in the figure can be easily opened. At that time, the passage on the left side of the figure which is not in operation is closed.

Example 3

[0025] The first heat insulating sheet 8 is provided with weights 17 and 17 at both ends in the figure, and the end 8b of the heat insulating sheet 8 is normally shown by a broken line 8b on the right side of the support base 9 in the figure. In addition, it is extended on a support base 91 adjacent to the passage space and is restrained by the weight 17.

The end portion 81b of the first heat insulating sheet 81 on the adjacent support base 91 is extended on the support base 9 so as to overlap the end portion 8b of the force heat insulating sheet 8 which is naturally suspended in this embodiment. May be.

[0026] When the worker pushes the support base 9 to form a passage, the end 8b of the heat insulating sheet 8 is folded and installed on the support base 9 as indicated by a solid line 8c.

Or, it may be naturally suspended as in the case of the end 8 lb of the heat insulating sheet 81.

[0027] Since the work passage can be easily opened and closed in this manner, the support pitch without deteriorating workability, and therefore the arrangement pitch of the seedbed containers can be improved, the whole can be made compact, and the thermal efficiency can be improved.

[0028] A second heat insulation sheet 89 is installed above the whole of the plurality of seedbed containers 1 and 11 at least enough to allow an operator to walk, and the second heat insulation sheet 89 is a fixed base. It covers the whole of the 19 rows, and its end is overlapped with the end of the heat insulation sheet 8 of the stand corresponding to the fixed stand of the end row, and the inside is sealed.

As a result, there is little energy loss when adjusting the internal temperature.

Example 4

[0029] In Example 1 above, with the first heat pipe 5 (51) embedded in the culture soil 2 immediately before the seedling 3 is planted, the inner pipe 5a (51a) has a constant high-temperature water. Pumped and radiated The culture soil can be sterilized at high temperature by heating with far infrared rays.

In this way, the culture soil can be easily disinfected in a state where the culture soil without spraying a bactericide or replacing the culture soil is accommodated in the nursery container.

Example 5

[0030] This example is a case where the seedling 3 of the cultivated plant in Example 1 is a strawberry seedling.

In Figure 1, after planting seedlings, the temperature-controlled air radiated from the opening of the third pipe 6c covering the second heat pipe 6 is applied to the strawberry seedlings, which corresponds to the night cooling. Then, during the seedling raising, the far infrared rays emitted from the first heat pipe 5 cool the crown part 3a of the strawberry seedling 3, that is, the temperature of the crown part 3a is increased. Strawberry seedlings are planted in the culture soil so as to adjust to a predetermined temperature, and then promote the differentiation of flower buds.

And during the next fruiting, the temperature-controlled aerodynamic force radiated from the opening of the third pipe covering the second heat pipe 6 increases the sugar content of the fruit and hits the fruit of the strawberry. Suppresses softening of the skin and pulp.

In Fig. 1, seedling 3 is a force tigo seedling 3 schematically shown by only one confectionery and one rhizome. Specifically, the seedling 3 is a single "crown part" that contacts the culture soil 2. It consists of 3a, multiple flower buds, leaf stems, and runners that extend upward from the crown region, and multiple rhizomes that extend below the crown region force into the culture soil!

[0031] In this way, temperature control that is essential for the strawberry forcing cultivation, such as night cooling, cooling of the crown part, and air conditioning of the fruit, is limited to the target part and is also temporal in terms of temperature. In addition, since it can be performed accurately and without the need for operations such as transport by workers, super-enhanced multiple cultivation throughout the year of strawberries is put to practical use for the first time by the present invention.
