Abstract
Description
Technical Field
[0001] This utility model relates to the field of blueberry cultivation facilities, and in particular to a blueberry facility cultivation system based on a conventional greenhouse. Background Technology
[0002] Blueberries are small berries with a beautiful blue color, covered by a layer of white bloom. The flesh is delicate, and the seeds are extremely small. Blueberries weigh an average of 0.5 to 2.5 grams, with a maximum weight of 5 grams. They are 100% edible, have a sweet and sour taste, and a refreshing aroma, making them a delicious fresh fruit.
[0003] While blueberries are expensive, they are relatively difficult to cultivate. Compared to many fruits, blueberries have more demanding growing conditions. As a plant with specific light requirements, light management is crucial during cultivation. Ordinary greenhouse facilities are not suitable for blueberry cultivation; they only provide rain protection and cannot regulate light. Intelligent greenhouses, on the other hand, require reconstruction and are costly. Summary of the Invention

[0009] Furthermore, the outer layer is a shading net with a light-blocking rate of 50%±2%, and the inner layer is a scattering film with a light transmittance of 70%±5%.
[0010] Furthermore, the outer layer and the inner layer are respectively connected to a film winding machine, and the film winding machine enables the two-layer rolling switching.
[0011] Furthermore, the suspended supplemental light is an LED supplemental light, including red LEDs and blue LEDs, with the ratio of red LEDs to blue LEDs being 7:3.
[0012] Furthermore, the LED fill light is connected to the canopy via a liftable rod.
[0013] Furthermore, the reflective film has a 5cm ventilation seam at its edge, and a weed control fabric with a pore size of 0.5mm is laid underneath the film.
[0014] Furthermore, the reflective film has uniformly perforated surfaces.
[0015] Specifically, the diameter of the perforations on the reflective film is 2cm, and the perforations are distributed in a plum blossom pattern, with 25±2 per square meter.
[0016] Furthermore, the temperature and humidity control device includes a water curtain, micro-sprayers, and a fan.

[0023] In the description of this utility model, it should be understood that the description indicating the orientation or positional relationship is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this utility model and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model.
[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "set up," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0025] The technical solution of this utility model is as follows:
[0026] Please see Figure 1 As shown, this utility model discloses a blueberry facility cultivation system based on a conventional greenhouse, comprising:
[0027] —A double-layer shading device, installed at the top of the canopy, comprising an outer layer 1 and an inner layer 2 that can be switched with each other;
[0028] —Supplemental lighting device, installed inside the greenhouse, including a suspended supplemental light 3 and a reflective film 4 laid on the ground;
[0029] —Temperature and humidity control device.
[0030] In a specific embodiment, the double-layer sunshade device is detachable and includes an outer layer 1 of aluminum foil sunshade net (shading rate 50%±2%, for summer use) and an inner layer 2 of scattering film (light transmittance 70%±5%, scattering rate ≥80%, for winter use), which can be quickly switched by a film roller.
[0031] More specifically, the top of the shed is a double-layered guide arch frame, with guide rods at the ends forming slide rails, through which the electric film roller 5 moves. The shade net is set on the outer arch frame, and the diffuser film is set on the inner arch frame. One end of the shade net or diffuser film is connected to the top, and the other end is connected to the electric film roller 5, which is used to roll or release the film (the corresponding film rollers are symmetrically arranged, each rolling half).
[0032] Shading nets and diffuser films are used in summer and winter respectively. The main function of shading nets is to cool down, while the main function of diffuser films is to keep warm.
[0033] In one specific embodiment, the suspended fill light 3 is a suspended LED fill light device.
[0034] The ratio of red light (wavelength 660nm) to blue light (450nm) is 7:3, with a light intensity of 150-200 μmol·m. - ²·s - ¹.
[0035] Installation height is dynamically adjustable: 60cm from the canopy during the budding stage → 40cm during the fruit expansion stage (controlled by an electric lifting rod).
[0036] In a specific embodiment, the ground reflective film 4 is made of PET aluminized film (reflectivity ≥85%, thickness 0.12mm), with uniformly distributed circular perforations of 2cm diameter on the surface (aperture rate 15%, perforation spacing 20cm). The perforations are arranged in a quincunx pattern, with 25±2 perforations per square meter, providing good air permeability. Figure 2 As shown;
[0037] The spectral matching between the reflective film 4 and the supplementary light 3 is as follows:
[0038] The reflective film 4 has a reflectivity of ≥80% in the 400-700nm wavelength band, and a peak reflectivity of 88%±2% in the 660nm red light band.
[0039] When increased light is needed, such as during the fruit expansion period, the supplemental light intensity should be increased to 200 μmol·m⁻²·s⁻¹, with a daily supplemental light duration of 6-8 hours. Using supplemental lighting (3) in conjunction with reflective film (4) to achieve the above light intensity conditions can improve growth.
[0040] In one specific embodiment, a 5cm ventilation gap is left at the edge when the reflective film 4 is laid, and a weed control fabric 6 with a pore size of 0.5mm is laid under the film, such as... Figure 3 As shown.
[0041] In a specific embodiment, the temperature and humidity control device includes a triple temperature and humidity control device consisting of a water curtain 7, a micro-sprayer 8, and a fan 9. Specifically, it includes a honeycomb paper water curtain 7 (thickness 12-15cm), a PVC micro-sprayer belt 8 (atomized particle size <100μm), and a suspended axial flow fan 9 (diameter 40cm, power 80W) at a height of 2.5m, with one unit arranged every 8m to form an air circulation speed ≥0.3m / s.
[0042] After further optimization, temperature and humidity are synergistically controlled:
[0043] 1. Install automatic roll-up windows on the side walls (opening range 0-100%).
[0044] 2. Suspend axial flow fans (40cm in diameter, 80W in power) at a height of 2.5m, with one unit every 8m to form an air circulation speed ≥0.3m / s.
[0045] 3. Micro-spraying system: PVC micro-spraying tape (0.3mm aperture, 1m spacing) is arranged along the ridge of the canopy. When the working pressure is 0.15MPa, the atomized particle size is <100μm.
[0046] 4. Water curtain optimization: A honeycomb paper water curtain (15cm thick, flow velocity 1.2m / s) is installed on the east side gable wall, which works in conjunction with the west side exhaust fan to create temperature difference ventilation.
[0047] In addition, the greenhouse is equipped with an automatic control device to control the opening and closing of the fans, water curtains and micro-sprinklers.
[0048] While specific embodiments of the present invention have been described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and not intended to limit the scope of the present invention. Equivalent modifications and variations made by those skilled in the art in accordance with the spirit of the present invention should be covered within the scope of protection of the claims of the present invention.
