Description

  The present invention relates to a technique for warming a strawberry crown when a strawberry is cultivated in a house by a planter, a raised type or the like.

  Conventionally, techniques for warming the periphery of a strawberry crown, increasing the plant height, and increasing the leaves are known. For example, it is the technique of patent document 1 * 2.

  The technology of Patent Document 1 is composed of a structure with a window having one or more windows and a passing medium through which a medium made of gas or liquid is passed, and is a space between the upper inner surface of the structure with a window and the culture medium. An environment-symbiotic space is formed, and the window and the structure with window can be divided into two or more. The temperature of the environment-symbiotic space is adjusted by sending the medium to the medium, and the temperature of the strawberry crown and its peripheral part is adjusted. I was trying to do. With such a configuration, piping is required, and a device for pumping the medium, a device for exchanging heat from the medium, and the like are also required, and the facilities become large and expensive. The technology of Patent Document 2 allows easy winding according to the shape of the plant, and even when bent, a uniform temperature can be obtained without occurrence of disconnection, and it can be manufactured to any size, and can be easily wound after use. It is a technology to make a long metal foil heater that is excellent in workability, safety and economy. However, this heater is expensive because it requires wiring and temperature control. Furthermore, when the above technology is applied to high-density cultivation in which a planter transplanted with strawberries is placed on the cultivation bench and the cultivation bench is circulated, it is necessary to perform piping and wiring for each bench, and connection with the moving bench It was difficult to break or break.

  In FIG. 3, the warming body 30 of the present invention warms the crown 3 a of the strawberry 3. The crown is the rhizome part of the strawberry stem. By warming this crown portion, the plant height can be increased, the leaves can be enlarged, and the inflorescence can be brought out quickly.

  The warming body 30 of the present invention is a mat-like body in which a heat storage material 36 is enclosed in a synthetic resin bag 35. As the heat storage material 36, a phase change material that exhibits a heat retaining effect in a predetermined temperature range between 15 degrees and 25 degrees is used. When the heat storage material 36 changes from a liquid to a solid, it releases heat to the vicinity near the freezing point, and maintains the temperature near the freezing point until it completely solidifies. And it restores to liquid (gel form) by warming. Since the heat storage material 36 can be used repeatedly, the running cost can be reduced. The warming body 30 is spread so as to cover the cultivated soil surface in the planter 2 in which the strawberries 3 are planted. The warming body 30 is divided into two parts before and after the size corresponding to the upper area of the planter 2, and covers the soil surface from before and after the planter 2. At this time, since the bag of the heating body 30 has flexibility and the heat storage material is in a gel shape, it can be adapted to the shape of the crown portion 3a of the strawberry 3. And the mobile cultivation apparatus 1 which transfers the planter 2 which spread the heating body 30 and cultivates a strawberry is arrange | positioned in the house 8, and absorption of the thermal energy of the heat storage material 36 of the heating body 30 is a house in daytime. It takes place when the temperature rises inside. Since this heat energy is absorbed by sunlight, the bag 35 enclosing the heat storage material 36 can be black to promote heat absorption. However, when the temperature is low due to rain or the like, the temperature in the house 8 may be increased by a boiler or the like, and the heat storage material 36 may absorb the heat energy, or the warming body 30 may be immersed in hot water and heated. It is also possible to warm using a microwave oven or the like.

  The warming body 30 can be configured as follows in order to efficiently warm the crown portion 3a. The size of the heating body 30 is configured to match the inner surface of the planter 2 so as to cover the accommodation upper surface of the planter 2. In other words, the two warming bodies 30 and 30 are arranged opposite to each other so that the upper surface of the soil contained in the planter 2 is symmetric in the front-rear direction (or point-symmetric), and the front and rear sides are butted and covered. . The heating element 30 is configured in a rectangular shape in plan view, the length in the longitudinal direction is set to the inner dimension in the longitudinal direction of the planter 2, and the length in the short direction is half the length in the short direction of the planter 2. . Further, in order to efficiently heat the crown portion 3a without damaging the crown portion 3a, the warming body 30 of the first embodiment, as shown in FIG. 3 and FIG. Are formed on the butted side 30a facing each other at a predetermined interval in accordance with the cultivation interval of the strawberries. The recess 30b has a semicircular shape large enough to contact the periphery of the crown 3a of the strawberry 3. A connecting member 30c formed of a hook, a hook-and-loop fastener, or the like is appropriately disposed on the abutting side 30a so as not to be opened at the abutting side due to the unevenness of the soil. The warming body 30 configured in this way can cover the cultivation surface by spreading the strawberries in the planter 2 and then spreading the strawberries from the front and rear directions and connecting the front and rear heating bodies 30 and 30 with the connecting member 30c. it can. However, the number of the concave portions 30b and the number of the connecting members 30c are not limited, and a heating body provided with two concave portions 30b by shortening the longitudinal direction, a heating body provided with three or the like, and the like in the planter 2 It can also be configured to divide and lay in a plurality.

  The warming element 31 of the second embodiment is substantially the same as the first embodiment, and only the structure of the abutting side 31a is different. Therefore, the configuration of the abutting side 31a will be described. As shown in FIG. 4 (b), cuts 31b, 31b,... Are formed on the butt edge 31a on one side in the longitudinal direction in accordance with the cultivation interval of strawberries. When the crown part 3a of the strawberry 3 is positioned in the notch 31b, the notch 31b opens according to the size thereof, opens largely unnecessarily, and heat does not escape, and the heating element 31 is inserted into the crown part 3a without a gap. The crown portion 3a can be heated efficiently. Even if the position of the crown 3a (transplant position) is slightly shifted, the extent of the cut 31b is different, and the crown 3a is not damaged. Further, the connecting member 31c can be provided at an appropriate position.

  The warming body 32 of the third embodiment is substantially the same in configuration as the first embodiment, and only the structure of the butted side 32a is different. Therefore, the configuration of the butted side 32a will be described. As shown in FIG. 4C, the butted side 32a on one side in the longitudinal direction is formed in a wave shape by alternately arranging a plurality of concave portions 32b and convex portions 32c. The concave portion 32b and the convex portion 32c that face each other when the heating bodies 32 and 32 are abutted against each other are fitted to cover the accommodation upper surface of the planter 2 without a gap. However, the shape of the concave portion 32b and the convex portion 32c is not limited to a semicircular shape, and may be a triangular shape, a quadrangular shape, or the like. When the warming body 32 is laid on the planter 2, the gap between the concave portion 32b and the convex portion 32c is widened at the portion where the crown portion 3a is located, and can be warmed efficiently in a state where it is in contact with the crown portion 3a. Further, since the bag 35 for storing the heat storage material 36 of the heating body 32 is made of a synthetic resin having flexibility, the convex portion 32c of the portion where the crown portion 3a is located is pushed into the inside of the main body side, thereby forming the convex portion. The portion 32c can be recessed, and the convex portion 32c can be prevented from being damaged by being pressed against the crown portion 3a.

  As shown in FIGS. 4 (d) and 4 (e), the heating elements 33 and 34 of the fourth embodiment are sized to enter the accommodation upper part of the planter 2, and the outer shape is a circular heating element shown in FIG. 4 (d). 33 or the rectangular heating element 34 shown in FIG. The warming bodies 33 and 34 are formed with insertion holes 33a and 34a through the crown portion 3a in the center in accordance with the size of the crown portion 3a of the strawberry, and cuts 33b and 34b from the outer periphery to the center direction (radial direction). Is formed. In addition, connecting members 33c and 34c formed of hooks, hook-and-loop fasteners, etc. may be appropriately disposed on the divided sides so that the notches 33b and 34b do not open at the divided portions due to unevenness of the soil or the like and the heating efficiency is not lowered. it can. After the strawberry 3 is transplanted to the planter 2, the warming bodies 33 and 34 configured in this way are installed so as to open the notches 33b and 34b one by one and pass through the crown portion 3a to cover the culture soil surface.

  As described above, the warming body 30 (or 31, 32, 33, 34) is arranged around the crown portion 3a of the strawberry 3 cultivated in the planter 2, and the planter 2 is placed on the cultivation bench 10. When the strawberry 3 is cultivated while being circulated by the first vertical conveying device 20A, the first horizontal conveying device 40A, the second vertical conveying device 20B, and the second horizontal conveying device 40B, it receives sunlight during the day. Thus, the temperature inside the house 8 rises, and when the temperature rises above a predetermined temperature (melting point), the heat energy is absorbed and stored in the heat storage material 36. When the heat storage material 36 undergoes a phase change from the solid phase to the liquid phase, the heat storage material 36 absorbs ambient heat and tries to maintain the temperature near the melting point. Can be prevented from being exposed to high heat. When the ambient temperature decreases at night and falls below the melting point at night, the heat storage material 36 can dissipate heat when the phase changes, and warm the crown portion 3a.

  As described above, the strawberry 3 is planted in the planter 2 and placed in the house 8, and the warming body 30 formed in a mat shape by enclosing the heat storage material in a flat bag is formed on the side of the strawberry crown 3a. Since the warming body 30 is warmed and stored due to a rise in temperature in the house 8 during the daytime, the crown part 3a is warmed by the heat dissipation of the warming body 30 when the temperature is lower than the solidification temperature of the heat storage material at night. It is possible to warm the crown portion 3a of the strawberry 3 without the need for sensors, piping, temperature management sensors, control devices, etc., and to promote the growth of the strawberry 3. The warming body 30 (31, 32, 33, 34) absorbs and stores heat in the heat storage material 36 due to the temperature rise in the house 8 during the daytime, and the crown portion 3a is absorbed by the heat storage material 36 at night. Because it can be warmed up, energy such as oil and electricity is unnecessary and can be used over and over again, saving energy and reducing costs.

  And since the recessed part 30b is formed in the one side of a longitudinal direction according to the planting space | interval of the strawberry 3 and the heating body 30 is formed in the rectangular mat shape, the heating body 30 of the strawberry 3 is made from both front and back sides. The concave portion 30b can be brought as close to the crown portion 3a as possible by inserting it under the leaf stem, and the crown portion 3a can be efficiently heated. Moreover, since the warming body 31 is formed in a rectangular mat shape, and the notch 31b is formed in one side in the longitudinal direction according to the planting interval of the strawberry 3, the warming body 30 is made of strawberry from both the front and rear sides. By inserting it below the leaf stem and positioning the notch 31b in the crown 3a, it opens according to the size of the crown 3a, opens largely unnecessarily, and heat does not escape, and the heating element 31 without any gaps. Can be brought close to the crown portion 3a, and the crown portion 3a can be efficiently heated.

  Further, the heating element 32 is formed in a rectangular mat shape, and the concave portions 32b and the convex portions 32c are alternately arranged on one side in the longitudinal direction and formed in a wave shape, so that the concave portions 32b and the convex portions 32c facing each other are formed. The gap between them opens according to the size of the crown part 3a, and it opens largely unnecessarily, so that heat does not escape, the heating element 32 can be brought close to the crown part 3a without any gap, and the crown part 3a is efficiently It becomes possible to warm up. Moreover, when the convex part 32c strongly hits the crown part 3a, the convex part 32c can be depressed by being pushed into the main body, and the crown part 3a can be prevented from being damaged.

  Further, the heating elements 33 and 34 are formed in a mat shape by enclosing a heat storage material 36 in a flat bag 35, and crown portion insertion holes 33a and 34a are opened at the center, and the crown portion insertion holes 33a are formed from the outer periphery. -Since notches 33b and 34b are formed toward 34a, the heating element 33 (34) can be arranged for each strawberry 3 strain, and all strawberry 3 even if the interval between the strains is irregular The crown portion 3a can be warmed.
