[0002] Strawberry is a fruit with high nutritional value. With the improvement of living standards in recent years, people's demand for strawberries has also increased. However, strawberries are short-day plants, so flower bud differentiation and fruiting are only carried out in autumn and winter, and no fruiting is carried out in summer, resulting in a decrease in the annual yield of strawberries, and strawberries are very expensive. In order to achieve year-round strawberry planting, a large number of strawberry planting factories have been born, that is, indoor planting, controlling the light time to simulate a short-day environment. Although the purpose of year-round planting is achieved, the existing strawberry planting factories have the substrate soil in the cultivation trough isolated from the earth.

DETAILED DESCRIPTION

[0039] The present invention is further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0040] It should be noted that the experimental methods described in the following embodiments are conventional methods unless otherwise specified, and the reagents and materials are commercially available unless otherwise specified; in the description of the present invention, the orientation or positional relationship indicated by the terms is based on the orientation or positional relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0041] like Figures 1 to 4 As shown, the present invention provides a strawberry cultivation device, comprising:

[0042] The planting trough 100 has two hollow side walls along the length direction, forming two accommodating chambers 11, which are filled with heat transfer medium; the heat transfer medium can be purified water, distilled water or tap water, because of its large heat capacity, it has a better effect of maintaining a constant temperature, and reduces the impact of the ambient temperature difference on the matrix soil layer 19 in the planting trough 100. The top of the accommodating chamber 11 is open for adding the heat transfer medium, and is covered with a sealing cover.

[0043] At least two temperature detectors are provided on the planting trough 100 and are used to detect the temperature of the heat transfer medium in the two accommodating chambers 11 respectively; the current temperature of the heat transfer medium can be known in real time, thereby providing a reference for turning on and off the heating. The temperature detector can be a temperature sensor, thereby providing a hardware basis for realizing automatic control.

[0044] A plurality of groups of infrared heaters 200 are arranged at intervals on both sides of the planting trough 100. The infrared heaters 200 include a mounting box 21 embedded in the accommodating cavity 11, an infrared heating lamp 22 installed in the mounting box 21, and a switch for controlling the on and off of the infrared heating lamp 22. When the switch is turned on, the infrared heating lamp 22 emits infrared rays to generate heat, which is transferred to a heat transfer medium. When the heat transfer medium is heated, the heat is transferred to the substrate soil layer 19 in the planting trough 100, thereby preventing the root and stem of the strawberry 600 plants from being too cold or suffering from cold damage.

[0045] A plurality of solar cells 300 are arranged at opposite sides of the planting trough 100 and are located below the mounting box 21. The solar cells 300 provide power to the infrared heater 200. When the strawberries are exposed to light, the solar cells 300 can absorb excess light and be charged. When the substrate soil layer 19 needs to be heated, the solar cells 300 provide power to the infrared heater 200, thereby starting the infrared heating lamp 22 to emit infrared rays to generate heat.

[0046] In the above technical scheme, when the strawberries are exposed to light, the solar cells 300 located on both sides of the planting trough 100 can fully absorb excess light and charge and store energy. When the temperature detector detects that the temperature of the heat transfer medium drops to a preset temperature value, the switch is started, and the solar cell 300 supplies power to the infrared heater 200, thereby the heat transfer medium is transferred to the matrix soil layer 19 in the planting trough 100, thereby avoiding excessive low temperature or cold damage to the roots and stems of the strawberry plants. Under the protection of the heat transfer medium, the heat of the infrared heater 200 will not burn the roots and stems of the strawberry plants in the matrix soil layer 19, and can keep them warm. When the temperature detector detects that the temperature of the heat transfer medium has risen to a preset temperature value, the switch is turned off, and the solar cell 300 stops supplying power to the infrared heater 200, thereby preventing the heat transfer medium from continuing to heat up, thereby avoiding burning the roots and stems of the strawberry plants in the matrix soil layer 19. During the whole process, there is no need to add additional electric energy to drive the air conditioner or floor heating. Instead, the excess light is fully utilized to accurately control the temperature of the substrate soil layer 19, thereby avoiding low temperature or cold damage to the roots and stems of the strawberry plants, saving costs while increasing strawberry yields.

[0047] In another technical solution, the planting trough 100 includes:

[0048] The bottom of the trough body 12 is provided with a plurality of pairs of legs 13 at intervals along the length direction. The bottom of the trough body 12 between the pair of legs 13 is in a downwardly concave arc-like shape. A liquid outlet pipe 14 is provided at the bottom of the trough body 12, and a valve is provided on the liquid outlet pipe 14. Watering and fertilizing are required during the strawberry planting process. When excess water or fertilizer is used, it can penetrate into the bottom of the trough body 12. By opening the valve, the excess waste liquid can be removed to prevent root rot.

[0049] The support filter layer 15 is laid in the tank body 12 and forms a liquid collection space 16 with the bottom of the tank body 12. The liquid collection space 16 is provided with a plurality of air holes 17 near the support filter layer 15. Air can enter the liquid collection space 16 from the air holes 17, thereby helping the matrix soil layer 19 to ventilate and prevent root rot. The support filter layer 15 can be made of a honeycomb grid-shaped plate, which has a stable support performance and excellent air permeability.

[0050] The breathable material layer 18 is laid on the supporting filter layer 15 ; the breathable material layer 18 is used for ventilation and supporting the matrix soil layer 19 to prevent the matrix soil layer 19 from falling into the liquid collecting space 16 . The breathable material layer 18 can be made of a combination of crushed stones of different particle sizes.

[0051] The matrix soil layer 19 is laid on the breathable material layer 18, and the matrix soil layer 19 is located within the height coverage range of the accommodating cavity 11. The matrix soil layer 19 is specifically selected according to different strawberry varieties.

[0052] In the above technical solution, during the strawberry planting and management, excess water or fertilizer liquid can penetrate to the bottom of the tank body 12, and the valve can be opened to remove the excess waste liquid to prevent root rot. By providing the support filter layer 15 and the air-permeable material layer 18, a stable support performance is provided to prevent the matrix soil layer 19 from falling into the liquid collection space 16, and the excellent air permeability is provided to prevent root rot.

[0053] In another technical solution, the longitudinal cross section of the trough body 12 is trapezoidal. The strawberry root system diverges downward, and the trapezoidal setting helps to increase the lower space and facilitates the solar cell 300 to absorb light.

[0054] In another technical solution, a pair of support strips 10 are provided on the inner side wall of the trough body 12 along its length direction, and the two sides of the support filter layer 15 are overlapped on the pair of support strips 10. Cultivating strawberries can easily lead to soil acidification, nutrient enrichment, secondary salinization, changes in soil physical and chemical properties, accumulation of soil harmful substances and other continuous cropping problems. Therefore, it is necessary to regularly replace the waste matrix soil layer 19 for adjustment and replace it with a new matrix soil layer 19. The detachable connection method is conducive to the replacement of the matrix soil layer 19 and improves efficiency. It is worth noting that the width of the support strips 10 should be set to be smaller than the minimum width inside the trough body 12.

[0055] In another technical solution, the bottom of the liquid collecting space 16 is inclined to the liquid outlet pipe 14 along the length direction of the tank body 12, which helps to drain away excess water or fertilizer liquid.

[0056] In another technical solution, the side wall of the installation box 21 facing the center of the planting trough 100 is in an arc shape that is concave toward the center of the planting trough 100 and is made of metal; the metal material has excellent thermal conductivity and can transfer heat to the heat transfer medium more quickly. The arc shape helps to increase the heat transfer area, thereby improving the heat transfer efficiency.

[0057] The side wall of the installation box 21 facing away from the center of the planting trough 100 is in an arc shape that is concave away from the center of the planting trough 100, and an infrared reflection layer is applied to the inner surface. The setting of the arc shape and the infrared reflection layer helps the infrared light emitted by the infrared heating lamp 22 to be concentrated and transferred toward the heat transfer medium with low loss, thereby improving the heat transfer efficiency.

[0058] In the above technical solution, by setting the shape, material and infrared reflection layer of the installation box 21, the heat transfer efficiency of the infrared heating lamp tube 22 is significantly improved and the heat loss is reduced.

[0059] In another technical solution, a plurality of battery brackets 400 are further included, and the battery brackets 400 include:

[0060] A pair of ear plates 41, the pair of ear plates 41 are arranged at intervals on one side wall of the planting trough 100;

[0061] A pair of support rods 42 , the lower ends of the pair of support rods 42 are respectively hinged to a pair of ear plates 41 , and slots are provided on the facing side walls of the pair of support rods 42 along their length directions; the support rods 42 can rotate relative to the ear plates 41 .

[0062] The two ends of the cross brace 43 are fixed on the side walls of a pair of support rods 42 . A support 44 is provided on the lower surface of the cross brace 43 . An adjusting short plate 45 is hinged on the support 44 . The adjusting short plate 45 can rotate relative to the support 44 .

[0063] The fixing rod 46 has two ends fixed on a pair of ear plates 41 and is located on the same side as the adjusting short plate 45 . A bearing 47 is sleeved on the fixing rod 46 ; the bearing 47 can rotate relative to the fixing rod 46 .

[0064] The telescopic rod 48 has one end fixed on the bearing 47 and the other end hinged on the adjusting short plate 45; the telescopic rod 48 can rotate relative to the fixed rod 46 by the bearing 47, and can be extended and retracted along its axial direction to adjust its length. The telescopic rod 48, the adjusting short plate 45, and the support 44 form a connecting rod activity form, and the supporting angle of the pair of supporting rods 42 can be adjusted and stably maintained at this angle through the telescopic rod 48, the adjusting short plate 45, and the support 44.

[0065] The rotation direction of the support rod 42, the rotation direction of the adjusting short plate 45, and the plane where the rotation direction of the bearing 47 is located are parallel to each other, and the axial direction of the telescopic rod 48 is parallel to the plane where the rotation direction of the bearing 47 is located;

[0066] The solar cell panel of the solar cell 300 is a flexible solar cell panel, the two ends of which are movably inserted into a pair of slots, and the lower surface of which is overlapped on the cross brace 43. The flexible solar cell panel has the advantages of being small and soft, and is convenient to be inserted into the slot in a detachable manner, and will not collapse under the support of the cross brace 43.

[0067] In the above technical solution, since the lighting arrangement of each plant factory is different and the growth conditions of strawberries are different, by providing a battery bracket 400, the light absorption angle of the solar panel can be adjusted conveniently and quickly, thereby improving the power generation efficiency.

[0068] In another technical solution, a PE film 500 is further included, which covers the substrate soil layer 19, and a planting belt 51 is opened on the PE film 500 along the length direction of the trough body 12;

[0069] The top of the side wall of the trough body 12 is provided with a plurality of strip-shaped protrusions 52 at intervals, and the part of the PE film 500 covering the protrusions 52 is provided with a fixing clip. Since the matrix soil layer 19 contains microorganisms and has a high water content, if the strawberry fruit is directly in contact with the matrix soil layer 19, it is very easy to be damaged by stains of microorganisms, etc. By providing the PE film 500, the strawberry fruit and the matrix soil layer 19 can be isolated, and the pollution, deterioration and damage of the strawberry fruit can be reduced. Through the provision of the protrusion 52, the PE film 500 can be slightly suspended above the matrix soil layer 19 to avoid blocking the ventilation of the matrix soil layer 19, and the strawberry fruit can also be supported farther from the matrix soil layer 19. The strawberry 600 is planted into the matrix sealing layer 19 through the planting belt 51, and can be watered and fertilized into the matrix sealing layer 19 through the planting belt 51.

[0070] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the implementation modes, and they can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and the illustrations shown and described herein.
