Description

Technical Field

[0001] This invention relates to the field of morel mushroom cultivation technology, specifically to a morel mushroom cultivation greenhouse that is easy to control in terms of light. Background Technology

[0002] Morel mushrooms, as a high-value and rare edible fungus that is both medicinal and edible, are extremely sensitive to the light threshold of their growth environment. Direct sunlight can easily cause mycelial burns and wilting, fruiting body cracking and deformity, and reduced yield due to water loss. Insufficient light can lead to a series of production problems, such as excessive humidity in the greenhouse, large-scale proliferation of miscellaneous fungi, poor ventilation and light transmission, high incidence of deformed morel mushrooms, and a significant decline in the overall yield of high-quality cultivated morel mushrooms. Therefore, precise control of light is the key to determining the yield and commercial grade of morel mushrooms.

[0003] Currently, most conventional morel cultivation greenhouses use a fixed, single-layer shading structure, which cannot accommodate the dynamic light-changing cultivation process of morel mushrooms at different growth stages. Furthermore, they can only achieve two single states: full shading or full openness. Since the angle of sunlight varies throughout the day, the amount of light received by the morel mushrooms in the greenhouse is inconsistent even when fully open, resulting in uneven growth.

[0004] In summary, a special greenhouse needs to be designed that can adjust the light intensity in layers according to the different growth stages of morel mushrooms. Summary of the Invention

[0005] The purpose of this invention is to provide a morel mushroom cultivation greenhouse that is easy to control the light, so as to solve the technical problems of uneven lighting and ineffective shading in the existing greenhouse.

[0006] To solve the above-mentioned technical problems, the present invention specifically provides the following technical solution: A morel mushroom cultivation greenhouse with easily controlled light includes: a greenhouse body having multiple sets of vertically and parallelly arranged main frames, with adjacent sets of main frames connected as a whole by connecting rods; the entire top surface and both ends of the greenhouse body are covered with a greenhouse film; multiple sets of first shading nets, stacked and laid in parallel layers from top to bottom on the greenhouse film located on the entire top surface of the greenhouse body, each set of shading nets being divided into two symmetrically distributed shading curtains along the central axis of the greenhouse body; wherein the multiple sets of first shading nets have different shading rates; second shading nets, with the second shading nets laid vertically on the main frames located at both ends of the greenhouse body; a first winding roller, with each shading curtain corresponding to a first winding roller, one end of the shading curtain being fixed, locked, and wrapped around the outer periphery of the corresponding first winding roller; the first winding roller is horizontally arranged along the central axis of the greenhouse body on the greenhouse body. The top of the greenhouse body is positioned at the central ridge line, with two first retractable rollers symmetrically arranged corresponding to the two sunshade curtains in the same group. Supports are vertically mounted on the main frames at both ends of the greenhouse body, and the two ends of the first retractable rollers rotate relative to the support at their respective ends. A first counterweight is fixedly mounted on the free end of each sunshade curtain away from the first retractable roller, parallel to the first retractable roller. A drive motor is mounted on the support, with each first retractable roller corresponding to a drive motor, each drive motor being independently controlled to drive the corresponding first retractable roller to rotate forward or backward. A sliding groove is formed by multiple proportionally increased outer frames evenly spaced vertically on all the main frames, with the space between two adjacent outer frames forming the sliding groove. The first counterweight passes through all the sliding grooves and slides within them.

[0007] Furthermore, the first shade net comprises at least three sets: a fully black shade net laid independently in layers, a 30% shade net, and a 50% shade net.

[0008] Furthermore, baffles are provided at both ends of the configuration rod in a direction perpendicular to its own axis to prevent the end of the first counterweight rod from disengaging from the outermost groove.

[0009] Furthermore, a cavity is provided at the central ridge position of the top of the greenhouse body to enclose all the first roll-up rollers. The two side walls of the cavity are provided with straight grooves along the horizontal direction corresponding to all the first roll-up rollers for the sunshade curtain to enter and exit. The outer frame is connected to the cavity, and the sliding groove is connected to the corresponding straight groove.

[0010] Furthermore, the upper and lower groove contact surfaces of the straight groove are provided with rotating rollers, and the outer edge of the rollers makes rolling contact with the sunshade curtain.

[0011] Furthermore, within the cavity, corresponding to each of the first winding and unwinding rollers, multiple support seats are provided at equal intervals along the horizontal direction directly below the first winding and unwinding roller. Two spring telescopic rods are symmetrically arranged vertically upward on each support seat, and rollers are provided at the telescopic ends of the two spring telescopic rods. The two ends of the rotating shaft of the roller are respectively rotatably engaged with the telescopic ends of the two spring telescopic rods, and the rollers are always in rolling contact with the corresponding sunshade curtain during the winding or unwinding process of the first winding and unwinding roller to support the first winding and unwinding roller.

[0012] Furthermore, two sets of rollers are symmetrically arranged on the support base along the axis corresponding to the first winding and unwinding shaft. Both sets of rollers are located at the extension and retraction ends of the corresponding spring telescopic rods and are in rolling contact with the sunshade curtain to flexibly flatten and correct the sunshade curtain in real time during the winding process, and to compact the gaps between the layers of the sunshade curtain.

[0013] Furthermore, the main frame includes an upper arc-shaped main frame and a lower rectangular main frame, which are integrally formed; the second shading net covering the arc-shaped main frame is a completely black shading net; the second shading net covering the rectangular main frame is provided in multiple sets, namely a completely black shading net, a 30% shading rate shading net, and a 50% shading rate shading net, and the type of the second shading net is selected according to the type of the first shading net covering the entire top surface of the greenhouse body.

[0014] Furthermore, at the top of the rectangular main frame located at both ends of the greenhouse body, a second winding roller is provided for each group of the second shade net along its own length direction. One end of the second shade net is fixedly locked, snugly wrapped and stored on the outer periphery of the corresponding second winding roller. The second winding roller is equipped with an integrated elastic automatic rewinding spring winding mechanism. A second counterweight rod is provided at the free hanging end of the second shade net. The second counterweight rod is provided with a positioning ring. A positioning hook is provided at the bottom of the rectangular main frame corresponding to the positioning ring. The positioning ring can be sleeved on the positioning hook.

[0015] Furthermore, a special mushroom growth lamp is installed on the inner side of the greenhouse body below the cavity to provide supplemental lighting for the mushrooms located inside the greenhouse body.

[0016] Furthermore, the greenhouse body is equipped with multiple planting compartments, in which mushrooms are grown. Each planting compartment is equipped with a plasma sterilizer, an ultrasonic humidity generator, an air source heat pump, a carbon dioxide sensor, a humidity sensor, an oxygen sensor, and a mushroom-specific growth lamp. All devices are electrically connected to the intelligent control system. The intelligent control system has a built-in linkage control module that receives real-time monitoring data from each sensor and controls the operation of the mushroom-specific growth lamp, plasma sterilizer, ultrasonic humidity generator, and air source heat pump in a coordinated manner, thereby achieving fully automatic control of the mushroom growth environment within the planting compartments.

[0017] Compared with the prior art, the present invention has the following advantages: By setting up multiple layers of first shade nets with different shading rates and independently deploying them, shading can be freely combined as needed. Each layer of first shade net consists of two shade curtains, equipped with an independent drive motor for one-to-one electronic control of opening and closing. According to different light angles, the shade curtains on one side are opened, closed, and rolled up, precisely matching the differentiated low-light growth needs of morel mycelium germination, primordia differentiation, and fruiting body expansion, thereby reducing the problems of deformed and dead mushrooms caused by strong light stress from the source.

[0018] The first shading net on the roof and the second shading nets at both ends of the greenhouse are installed in a synchronized and graded manner, and can be opened and closed in unison to adjust the light, completely sealing off the blind spots of light leakage at the ends and sides, and ensuring a balanced distribution of light and shadow throughout the greenhouse. The morel mushrooms in the entire greenhouse grow in a synchronized and uniform manner, which facilitates unified field management of water, fertilizer, temperature and humidity.

[0019] Equipped with a built-in mushroom-specific growth light, it can automatically supplement light on cloudy or rainy days and in winter when there is little sunlight, breaking the limitations of natural weather light, shortening the growth cycle of morel mushrooms, enabling year-round multi-crop cultivation, and significantly increasing the planting yield per unit area of ​​the greenhouse.

Detailed Implementation

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] like Figure 1 As shown, this invention provides a preferred embodiment of a morel mushroom cultivation greenhouse that allows for precise light control. Multiple sets of first shading nets with differentiated shading rates are installed outside the greenhouse body 1. These nets are arranged in a layered, independently attached structure, allowing for flexible superposition and combination of shading elements to adapt to the light thresholds at different growth stages of the morel mushrooms. Each layer of the first shading net is divided into two symmetrical, separate shading curtains 5. Each set of shading curtains 5 is matched with an independent drive motor 9 to achieve one-to-one electronic control for automatic opening and closing. This allows for targeted and precise opening and closing of the shading curtains 5 on one side, adapting to flexible, light-shielding cultivation conditions across the entire area, taking into account the real-time outdoor sunlight deflection angle.

[0025] The following is a detailed description of the overall supporting structure: The main body of the greenhouse adopts a standardized, contiguous, prefabricated all-steel structure for specialized cultivation. The overall configuration is specially designed to meet the exclusive growth environment of morel mushrooms, which requires high humidity, low light, ventilation, and stable temperature. Inside the greenhouse, there are pre-planned standardized areas for mushroom beds, a closed-loop safety inspection walkway, standardized matching docking points for all-area spray watering, and integrated intelligent monitoring points for temperature and humidity, making it suitable for large-scale, contiguous, standardized cultivation.

[0026] The greenhouse body 1 is equipped with multiple sets of equidistant, vertically parallel, integrated high-strength load-bearing main frames 2. The spacing between each set of main frames 2 is precisely controlled within the optimal range of 1.2 meters to 1.5 meters, simultaneously taking into account the overall structural strength of the greenhouse against wind and snow loads, the three-dimensional ventilation and permeability of the greenhouse, and the suitability of effective lighting. Adjacent sets of integrated main frames 2 are precisely connected by hot-dip galvanized thickened high-strength connecting rods 3 and bidirectional locking bolts. Key stress points are reinforced by multi-point welding and reinforcement processes. The entire closed-loop rigid integrated main frame system avoids safety hazards such as loosening and displacement of the main frame 2, local stress concentration deformation, and collapse in extreme weather under long-term outdoor service conditions, thus ensuring the long-term stability and reliability of the greenhouse structure.

[0027] The greenhouse body is fully covered with a high-density, anti-aging agricultural edible fungi-specific greenhouse film, with complete outer facade at both ends. The film is a specially selected functional film for morel cultivation, which is resistant to fog droplet exudation, UV aging, low-temperature cracking, and high toughness and tear resistance. The edges of the film are secured with special slot strips and buckles for full sealing. All seams are sealed with special hot melt sealant, which fully takes into account the core basic functions of rainproof and seepage prevention, heat preservation and heat storage, physical blocking of stray light, and constant humidity control inside the greenhouse. At the same time, it enhances the anti-aging and durability performance under extreme outdoor conditions such as sun exposure, rain, and high and low temperature fluctuations, and is suitable for continuous operation of large-scale open-air cultivation all year round.

[0028] Multiple sets of first-level shading nets serve as the core layered and graded precise light control components of the greenhouse. They are stacked in parallel layers from top to bottom, closely fitted and orderly laid on the entire top surface and outer surface of the greenhouse body 1, with each layer laid out without interfering with the others.

[0029] Each set of first shade nets is precisely and evenly cut into two independent shade curtains 5 of completely identical specifications and symmetrically arranged along the longitudinal center axis of the greenhouse body 1. The two symmetrical shade curtains 5 can be synchronously and smoothly opened and closed, and the opening degree can be adjusted steplessly, effectively ensuring uniform and consistent shading coverage of the entire roof, without any dead corners of shading zones or blind spots of abnormal light transmission, creating a homogeneous and soft light environment throughout the entire area.

[0030] Multiple sets of first shading nets adopt an independent layered isolation layout process, with no adhesion or friction between the layers, no structural interference between them, and no superposition of pressure and stress between them. Each set of first shading nets is matched with a complete closed-loop electronic control retraction and extension drive assembly, which supports independent start and stop control of a single set and arbitrary ratio linkage start and stop control of multiple sets. It can flexibly match the full-area gradient shading rate according to the real-time light intensity, and has extremely strong light control adaptability.

[0031] The outer facades at both ends of the greenhouse body 1 correspond to the entire area of ​​the main frame 2, and a second shade net 6 is laid tightly and completely covering the entire vertical height. The second shade net 6 and multiple sets of first shade nets on the top surface are opened and closed in real time in a closed loop, and the shading is matched synchronously. This can block the side stray light interference from the facades at both ends of the greenhouse, the intrusion of low-angle oblique backlight in the morning and evening, and the side penetration of strong light reflected from the surrounding environment of the field plot into the greenhouse. It completely eliminates the traditional cultivation greenhouses that only provide unidirectional shading from the top surface and allow light to leak through the facades at both ends, which leads to the disordered fruiting sequence of morel mushrooms in the corner areas of the greenhouse, the high incidence of deformed mushrooms, and the uneven growth of mycelium in large-scale production. It comprehensively and three-dimensionally encloses and constructs a unique cultivation microenvironment with uniform soft light, constant temperature and humidity, and light-proof and clean environment inside the greenhouse.

[0032] Regarding the structure of the sunshade curtain 5 retraction drive assembly, this embodiment provides the following examples, such as... Figure 2 and Figure 5 As shown, the specific structure is as follows: Each symmetrically arranged sunshade curtain 5 is exclusively matched with a first roll-up roller 7. The starting edge of the sunshade curtain 5 close to the roller is tightly and smoothly wrapped and stored on the outer wall of the corresponding first roll-up roller 7. Throughout the entire rolling process, the curtain body is flat and regular, without local wrinkles or arches, no one-sided offset or misalignment, and no stretching, loosening, deformation or damage, thus protecting the integrity of the sunshade net for a long time.

[0033] The first winding and unwinding roller 7 is made of thickened, rust-proof, hot-dip galvanized seamless steel pipe, precisely cut and formed in one piece. The pipe wall is uniformly smooth and free of burrs and sharp edges, and the entire process is flexible and does not scratch the surface of the curtain. The roller is horizontally and precisely fixed along the longitudinal center axis of the greenhouse body 1 at the core stress position of the ridge line at the top of the greenhouse body 1. The overall pressure and stress are centered and do not deviate, resulting in extremely strong operational stability.

[0034] The main frame 2 located on both sides of the greenhouse body 1 extends vertically upward in an integrated form of a dedicated assembly bracket (integrated with the cavity 13 in the figure, not shown). The two ends of the first winding and unwinding roller 7 are in high-precision rotational sealing cooperation with the dedicated bracket on the corresponding side. The two first winding and unwinding rollers 7 corresponding to the two symmetrical sunshade curtains 5 in the same group are strictly coaxially and symmetrically arranged. The rotation speed is completely synchronized and the winding and unwinding operation stroke is precise and consistent. The rigidity ensures that the opening and closing of the curtains on both sides is accurate and the timing is synchronized without deviation.

[0035] Each sunshade curtain 5, located away from the free end of the first retractable roller 7, is fixed with an integrated solid galvanized first counterweight rod 10 along the horizontal axis parallel to the first retractable roller 7 using high-strength anti-corrosion and anti-rust bolts. The weight of the counterweight rod is precisely matched mechanically according to the actual coverage area and wind-receiving area of ​​each sunshade curtain 5. Relying on its own weight, it pulls the curtain down vertically and evenly throughout the entire process, effectively resisting the curtain from swaying, bulging, rolling up at the edges, and localized poor fit under outdoor strong wind conditions. It ensures that the sunshade curtain 5 operates smoothly and tightly during retraction and extension at all times.

[0036] All load-bearing supports have dedicated integrated installation stations on the outside. Each station is equipped with a waterproof, dustproof, and fully sealed dedicated drive motor 9. The motor integrates multiple safety protection modules, including automatic overload protection, immediate shutdown when stalled, instant power cut-off in case of leakage, and high temperature overload cooling. It is specifically designed for harsh outdoor operating conditions such as high humidity, dust, and large temperature differences between day and night inside greenhouses. It is safe, stable in operation, and has an extremely low failure rate.

[0037] Each of the first take-up and untake-down reels 7 is independently coupled to a dedicated drive motor 9, with precise speed control and independent electronic control throughout the entire process. The operation of each group of motors does not interfere with each other, does not compete for power or overload, and does not cause any linkage or jamming.

[0038] On-site operators can use the centralized intelligent electronic control panel inside the shed to individually control the precise start and stop of a single drive motor 9 in both forward and reverse directions, individually and finely adjust the opening degree of a single set of sunshade curtains 5, and individually lock the target shading level with one click. They can also use the entire area to coordinate the start and stop of all drive motors 9 with one click, and synchronously control the light evenly across the entire area.

[0039] The drive motor 9 rotates at a constant speed in the forward direction to drive the roller to smoothly roll up and store the sunshade curtain 5. When it rotates at a constant speed in the reverse direction, it can work with the first counterweight rod 10 to smoothly lower and unfold the sunshade curtain 5 without impact. The light-blocking opening can be continuously and steplessly adjusted from 10% to 100% with precision. It can accurately match the real-time light tolerance threshold of morel mushrooms at different growth stages as needed. The overall light control accuracy is controllable and adjustable, and the on-site operation is simple and easy to perform. Novice maintenance personnel can quickly learn the standardized operation.

[0040] The greenhouse body 1 consists of an integrated main frame 2 that extends vertically at equal intervals, forming multiple sets of equal-sized and proportionally heightened outer frames 11. The heightened dimensions are uniformly adapted to the full sliding operation stroke of the first counterweight rod 10, ensuring that the overall structure is subjected to balanced and uniform stress and does not undergo plastic deformation under long-term pressure. A regular and sealed limiting space is reserved between two adjacent sets of heightened outer frames 11 in the vertical direction, and an integrated cast-in-place horizontal guide groove 12 is formed. The inner wall of the groove 12 is finely polished to be smooth without burrs, protrusions, or sharp welding slag residue, providing full closed-loop protection to effectively prevent scratches on the surface of the curtain and collisions with structural components.

[0041] The first counterweight rod 10 is horizontally and fully installed inside all the sliding grooves 12, and its gap with the inner wall of the sliding groove 12 is precisely matched with high precision, forming a low-damping, low-wear, and highly smooth directional sliding fit structure. During the entire operation cycle of the sunshade curtain 5, the first counterweight rod 10 slides smoothly and horizontally along the sliding groove 12 without vertical jumping or swaying, lateral deviation, or front-back misalignment or jamming. The entire process is mechanically forced to guide and limit, ensuring the smooth and regular opening and closing of the sunshade curtain 5 from the bottom mechanical structure level, and completely eliminating high-frequency maintenance failures such as curtain deviation, layer jamming, and local misalignment.

[0042] To further optimize structural protection, an integrated anti-detachment limiting baffle 20 is formed by bending at both ends of the first counterweight rod 10, perpendicular to the central axis of the first counterweight rod 10. The baffle 20 adopts an outwardly protruding snap-on limiting structure design, which can accurately engage with the preset limiting slots on both sides of the corresponding slide groove 12, and dynamically limit the lateral displacement and vertical jump-off of the end of the first counterweight rod 10 in real time. This effectively avoids the associated faults such as derailment and jamming of the first counterweight rod 10, curtain skewing and deviation, and uneven force on the roller under long-term high-frequency reciprocating sliding conditions, and significantly reduces the frequency of equipment operation and maintenance and the cost of manual maintenance.

[0043] In a preferred embodiment, the first shading net is preferentially equipped with three sets of gradient standardized functional nets, arranged in an orderly layered manner from top to bottom: the first layer adopts a completely black, sealed, high-intensity shading net with a shading rate of ≥99.8%, specifically adapted to the core working conditions of morel mycelium closed dark light cultivation, low-temperature dormancy light protection, and strong light stress prevention during the weak mycelium stage; the second layer adopts a 30% low shading rate, high-breathability soft light net, adapted to the morel seedling slowing down stress, low-light hardening, and mycelium rejuvenation and growth stage; the third layer adopts a 50% medium shading rate, high-ventilation light control net, adapted to the core cultivation stage of morel fruiting body rapid expansion growth in the middle and late stages, moderate diffused light to improve quality and increase yield, and uniform coloring of mushrooms.

[0044] Meanwhile, by combining the second layer of 30% low shading rate breathable soft light mesh with the third layer of 50% medium shading rate ventilation light control mesh, a stable 70%-80% composite shading rate can be accurately matched to meet the needs of all-weather lighting scenarios.

[0045] On-site, the system can dynamically switch between precise light control modes based on the different weather conditions of the day, such as strong sunlight exposure, weak light scattering due to cloudy skies, and overcast or rainy conditions with little sunlight. This is combined with the entire growth cycle of morel mushroom mycelium germination, seedling growth, fruiting body enlargement, and mature harvesting. It completely replaces the outdated management mode of manual single-layer arbitrarily covering with nets, blindly lifting nets based on experience, and crudely adjusting light based on intuition, thus achieving standardized and intelligent management of the light environment.

[0046] To further improve the operational adaptability of the retraction drive assembly, enhance the smoothness of the sunshade 5's retraction and extension throughout its entire lifecycle, and reduce operational energy consumption and wear, such as... Figure 5As shown, this embodiment provides the following examples.

[0047] The greenhouse body 1 has an integrated, closed, riveted, and sealed protective cavity 13 at the core of the roof ridge. The cavity 13 fully covers all the first winding and unwinding rollers 7, all the power transmission ends of the drive motors 9, and all precision bearings and rotating parts. The two ends and the top of the cavity 13 are fully sealed with multiple layers of waterproof, dustproof, and bird and insect nesting prevention and sealing reinforcement treatment. This effectively isolates outdoor rainwater corrosion, dust accumulation and jamming, bird and insect nesting, and UV aging and failure. It greatly extends the service life of core transmission components such as rollers, drive motors 9, and precision bearings, and significantly reduces the incidence of transmission corrosion, operation jamming, and abnormal noise failures.

[0048] The symmetrical sidewalls on the left and right sides of the cavity 13 correspond precisely to the positions of each first roll-up and roll-down shaft 7. Straight, transparent, horizontal grooves 21 are opened in the same direction for the entry and exit of the curtain. All grooves 21 are standardized and coaxially aligned with no deviation. The top of the raised outer frame 11 is seamlessly and tightly connected to the sidewall of the cavity 13. The inner horizontal sliding groove 12 corresponds one-to-one with the straight grooves 21 of the cavity 13 and is coaxially and tightly connected, forming a fully enclosed and smooth path for the sunshade curtain 5 to enter and exit, without any hard bends, dead angles, local jams, or edge scraping points.

[0049] Meanwhile, the upper and lower contact surfaces of the straight groove 21 are embedded with wear-resistant, quiet, and low-resistance roller shafts 17. The outer edge of the roller shaft 17 adopts a smooth arc flexible structure design, which is in flexible rolling contact with the surface of the sunshade curtain 5 throughout the process. This efficiently transforms the traditional hard sliding dry friction into low-loss flexible rolling friction, which greatly reduces the probability of edge wear and tear, local aging and damage of the curtain, and effectively reduces the overall operating noise of the mechanism. This is suitable for the exclusive environment requirements of quiet, light-proof, stress-free, and high-quality cultivation of morel mushrooms.

[0050] Furthermore, multiple sets of directional guide rollers 25 are specially arranged inside the cavity 13 according to the actual operation trajectory of the sunshade curtain 5 during dynamic unwinding and rewinding. This precisely optimizes and controls the real-time unwinding and rewinding operation path of the sunshade curtain 5, effectively avoiding problems such as mutual contact and interference, tangling and knotting, and local squeezing and deformation between multiple layers of curtains, ensuring that the layers operate independently without interference.

[0051] Combination Figure 6 and Figure 7 As shown, in the sealed cavity inside the cavity 13, corresponding to the pressure point directly below each of the first take-up and take-down rollers 7, multiple sets of integrated fixed load-bearing support seats 14 are densely arranged at equal intervals along the roller axis; the support seats 14 are fully welded and fixed to the high-strength load-bearing base plate at the bottom of the cavity 13, so that the whole structure is stable under force, without shaking or displacement, and without resonance or abnormal noise.

[0052] Two sets of high-strength, wear-resistant spring telescopic rods 15 are symmetrically arranged vertically upward on each support base 14. The spring telescopic rods 15 have built-in high-strength, pressure-resistant, sealed return springs, which have sensitive elastic extension and contraction response, excellent rebound stability, and no risk of fatigue failure under long-term high-frequency pressure. The telescopic movable ends of the two spring telescopic rods 15 are equipped with a pressure-bearing, anti-slip, flexible roller 16 that rotates together. The outer edge of the roller 16 is fully covered with a thickened, flexible, wear-resistant, and anti-slip rubber buffer layer, which reduces noise and vibration, and provides a snug and anti-slip fit.

[0053] The roller 16 has two ends of its rotating shaft that are sealed and rotate in a closed manner with the telescopic ends of the spring telescopic rods 15 on both sides through sealed rotating seats. Under normal conditions, it relies on the adaptive elastic force of the spring to push upward and press against the lower surface of the sunshade curtain 5 in real time. Regardless of various working conditions such as idle winding, full-load heavy-load winding, low-speed smooth start and stop, and high-frequency reciprocating continuous operation, the roller 16 always flexibly fits against the curtain and adaptively elastically supports the first winding and unwinding roller 7. This effectively offsets the long-term self-weight bearing and deflection deformation of the middle of the large-span roller, and eliminates the curtain deviation, uneven winding, and edge misalignment caused by the bending and warping of the roller from the root. It is perfectly adapted to the stable and long-term operation of the long-span roller in the large-span continuous cultivation greenhouse.

[0054] Further optimization and reinforcement of the overall structure: two sets of synchronous pressure-bearing and correction rollers 16 are symmetrically arranged on the single support base 14 along the central axis of the first winding and unwinding shaft 7. The two sets of rollers 16 simultaneously and flexibly press the sunshade curtain 5 against the upper and lower working surfaces. During the dynamic winding and high-frequency reciprocating winding and unwinding of the sunshade curtain 5, the curtain body is flexibly flattened and shaped, automatically centered and corrected, and subjected to bidirectional compaction and bonding in real time. This automatically corrects minor deviations such as slight lateral offset, uneven tension on one side, and local stress imbalance. It also compacts residual air gaps and dust impurities between the winding layers, ensuring that each roll of the curtain body is dense and flat, the layers are tightly bonded without gaps, and the edges are aligned without misalignment or offset. This completely avoids common maintenance failures such as curtain bulging, surface wrinkles, chip wear, one-sided curling, and local jamming after winding, significantly improving the overall operational stability and long service life of the entire layered precision light control mechanism.

[0055] In this embodiment, the greenhouse body 1 and the integrated main frame 2 adopt a two-section composite structure with an integrated bending design. The upper section is a streamlined arc-shaped main frame that conforms to the natural streamlined wind-receiving structure of the greenhouse ridge, effectively dispersing wind pressure and reducing the overall wind resistance coefficient, significantly improving the overall wind resistance level and extreme weather protection capability of the greenhouse. The lower section is a regular closed rectangular main frame with a square and balanced stress distribution, convenient on-site splicing and assembly, and strong end-face adaptability, facilitating the full coverage and fitting of the second shading net 6 at the end face. The two main frame sections 2 are bent into shape as one piece, without secondary splicing gaps or stress concentration weak points, resulting in uniform and balanced structural strength throughout the entire area and sufficient structural safety redundancy.

[0056] Within the main frame 2 area located at both ends of the greenhouse, the second shading net 6, which covers and adheres to the outside of the arc-shaped main frame, is uniformly made of all-black, high-density, thickened shading net. It is specifically designed to close off stray light from both sides of the top ridge and strong light from high-altitude scattering, providing a basic light-shielding protection barrier all day long. The second shading net 6, which covers and adheres to the outside of the lower rectangular main frame, adopts a multi-component gradient-level matching layout mode, matching three standardized gradient specifications: all-black sealed shading net, 30% low shading rate shading net, and 50% medium shading rate shading net. These specifications correspond precisely to the three sets of first shading nets layered on the top surface, and the levels are completely matched.

[0057] In actual large-scale cultivation operations, on-site managers only need to match and switch the corresponding second shade net 6 to the appropriate setting of the first shade net currently in use on the roof with one click, based on the real-time shading setting of the first shade net currently in use on the roof. This achieves closed-loop unified and coordinated control of the shading rate of the entire greenhouse, including the upper and lower facades and the front and rear facades. The light distribution throughout the greenhouse is highly uniform, with no local light and dark color differences or uneven light at the corners. This precisely meets the stringent control requirements for the large-scale, standardized, and simultaneous fruiting of morel mushrooms.

[0058] like Figure 3 As shown, along the entire horizontal length of the main frame 2, the top of the rectangular main frame at both ends of the greenhouse body 1 is precisely fitted with a second retractable roller 18 corresponding to each set of second shade nets 6; the starting end of the second shade net 6 is sealed and fixed with a high-strength locking strip, and is flat, tightly wrapped and stored on the outer wall of the second retractable roller 18, which is compact and neat, does not occupy the effective cultivation space inside the greenhouse, and has no protruding shading points.

[0059] Each of the second winding and unwinding shafts integrates an automatic rewinding spring mechanism, eliminating the need for an external drive motor or additional electrical control wiring. Relying on the built-in high-strength spring's adaptive rebound force, the shade net can be automatically and quickly rewound and stored when idle, resulting in energy saving, simplified on-site maintenance, extremely low mechanical failure rate, and low maintenance costs.

[0060] like Figure 4 As shown, the second shade net 6 hangs freely and is fixedly equipped with a solid anti-slip and anti-corrosion second counterweight rod 22 at its lower end. This rigidity ensures that the end face of the curtain is lowered vertically and stably, and fits tightly against the outer wall of the main frame 2 without swaying or shaking. At the same time, it allows maintenance personnel to directly hold the second counterweight rod 22 to apply uniform pulling force to complete the lowering and alignment operation.

[0061] like Figure 4 As shown, the two ends of the second counterweight rod 22 are integrally welded to form corrosion-resistant and wear-resistant special positioning rings 23, and the bottom of the rectangular main frame is precisely welded with matching anti-disengagement positioning hooks 24 corresponding to the positioning rings 23.

[0062] After the maintenance personnel manually lower the second shade net 6 to the designated shading position, they can directly engage the end positioning ring 23 with the positioning hook 24 to quickly lock and fix the end face full-area shade net 6, which is wind-resistant and anti-swaying, and does not require manual positioning and fixing. When storing, the positioning ring 23 can be removed directly, and the curtain can automatically rebound and roll back neatly by the built-in spring force. A single person can quickly and efficiently complete the entire process of end face full-area light opening and closing control, greatly improving manual efficiency.

[0063] To further optimize on-site accessibility, a flexible opening and closing gap is reserved on the second sunshade net 6 covering the outside of the rectangular main frame, corresponding to the personnel entrance and exit of the main body 1. This allows the second sunshade curtain in the area corresponding to the entrance and exit to be opened flexibly for passage. At the same time, the overall structural integrity and light-blocking airtightness of the sunshade curtain are not affected throughout the process, and the normal automated opening and closing operation is not interfered with.

[0064] This implementation method is simultaneously equipped with an optimized internal lighting supplementation method to enhance adaptability to extreme low-light weather.

[0065] The lower part of the inner cavity of the greenhouse body 1 and the top integrated protective cavity 13 are centrally located below the entire area, and mushroom-specific growth lights 19 are laid along the entire length of the greenhouse body. The mushroom-specific growth lights 19 have the characteristics of being waterproof and moisture-proof, mildew-proof and antibacterial, low light decay and long-lasting, flicker-free and eye-protecting. The light emitted is soft and uniform, and will not burn the surface of fresh mushrooms or stimulate the normal germination and development of mycelium with strong light, which is suitable for the exclusive growth light environment of edible fungi.

[0066] The mushroom-specific growth light 19 can be linked with the greenhouse's intelligent real-time lighting monitoring module for automatic start-up and shutdown. During sunny, high-temperature periods, passive and precise light control is achieved solely through multiple layers of shading netting, eliminating the need for supplemental lighting equipment. On cloudy, rainy, foggy, or nighttime periods of low natural light, the system automatically activates the mushroom-specific growth light in a closed-loop supplemental lighting manner, precisely supplementing the effective dedicated spectral energy required for morel mycelial growth, fruiting body development, and photosynthesis, thus addressing the light deficiency in low-light environments.

[0067] The mushroom-specific growth light 19 works in tandem with the top-layered adjustable first shading net and the end-face zoned linked second shading net 6 to form a two-way intelligent collaborative system, creating a closed-loop linkage and balanced all-weather light environment control system. This system precisely controls the real-time light intensity, effective light duration, and exclusive spectral ratio within the greenhouse around the clock, comprehensively meeting the core light environment requirements of the entire lifecycle for high-yield and high-quality morel cultivation. It effectively improves the average weight of individual morel mushrooms, the uniformity of fruiting across the entire area, and the rate of high-quality finished products, while significantly reducing the proportion of deformed, weak, and substandard mushrooms. This significantly enhances the overall economic benefits of large-scale contiguous planting and the actual income of growers.

[0068] The mushroom-specific growth light 19 uses adjustable LED nano-wavelength lamp tubes for mushrooms, suspended 20-30cm above the substrate, with a light uniformity of ≥80%. Light control needs to be coordinated with temperature, humidity, and ventilation; optimizing light alone has limited effect. If the cap turns white, increase blue light by 10%-20%; if the stipe grows excessively, increase red light and reduce the light duration by 2 hours.

[0069] Morel cultivation requires precise control of the LED red and blue light ratio, light intensity, and light duration according to different growth stages, as well as environmental conditions such as temperature, humidity, and ventilation. At the same time, it is necessary to investigate and deal with any abnormal problems in order to ensure normal growth and high-quality output.

[0070] During the mycelial colonization period: The goal is to promote mycelial spread and form robust sclerotia. The ratio of red to blue light is 9:1, the light intensity is 200-400 Lx, and the light exposure is 6-8 h / d. Maintain a temperature of 15-18℃ and a substrate humidity of 60%-70%. Avoid direct sunlight and low light conditions.

[0071] Sclerotium maturation stage: Improve sclerotium plumpness and reserve nutrients. Use a red-blue light ratio of 8:2, light intensity of 300-500 Lx, and light exposure of 8 hours / day. Strengthen ventilation. Once the sclerotium turns brown and hard, it enters the next stage.

[0072] Primordial differentiation period: Accelerate primordium formation and increase its number. Use a red-blue light ratio of 6:4, light intensity of 600-800 Lx, and 10-12 h / d of light. Temperature should be 8-12℃, diurnal temperature range of 5-8℃, and air humidity of 85%-90%. Do not use single blue light.

[0073] During the fruiting body expansion period: promote stipe elongation and cap coloring. Use a red-blue light ratio of 5:5, light intensity of 800-1000 Lx, and light exposure of 10 h / d. Maintain a temperature of 12-15℃, substrate humidity of 70%-75%, and air humidity of 90%-95% to ensure uniform light exposure.

[0074] Three days before harvest: To consolidate coloring and improve the quality of dried products, use a red-blue light ratio of 4:6, a light intensity of 600-800 Lx, and 8 hours / day of light exposure; moderately reduce humidity to 85%, and stop light exposure one day before harvest.

[0075] When mushrooms exhibit abnormal growth, first check the light quality ratio, then adjust the light intensity and duration, and finally coordinate with temperature, humidity, and ventilation; regularly record parameters and growth status to facilitate quick problem identification.

[0076] Sparse and excessive mycelial growth: Excessive red light, light intensity or duration. Adjust the mixing ratio to 8:2, light intensity to 200-300 Lx, and light exposure to 6 h / d.

[0077] Primordial differentiation is low: light quality imbalance, insufficient light intensity, no temperature difference. Adjust the ratio to 6:4, light intensity to 600-800 Lx, and create a temperature difference of 5-8℃.

[0078] Primordial withering: Excessive blue light, excessive light exposure, and excessively low humidity. Reduce blue light to 5:5 / 6:4, light exposure to 10h / d, and increase humidity to 85%-90%.

[0079] Whitening of the cap: Insufficient blue light, low light intensity, uneven lighting. Increase the blue light ratio to 5:5 / 4:6 and the light intensity to 800-1000 Lx. Adjust the light strip.

[0080] If the stipe is thin and drooping: the red light is too low, the light intensity is insufficient, or the temperature is too high. Adjust the red light ratio to 6:4, the light intensity to 10h / d, and lower the temperature by 12-15℃.

[0081] Morel mushrooms have stringent and sensitive growth requirements for environmental parameters such as temperature, humidity, gas composition, and cleanliness. To further optimize the cultivation and growth environment of morel mushrooms, improve the precision of environmental control, and reduce the interference of uncertain external environmental factors on the development of mycelium and fruiting bodies, this embodiment optimizes the planting structure and supporting control system, and provides the following specific examples.

[0082] The greenhouse itself is divided into several independently set up planting compartments. Morel mushrooms are planted and cultivated inside the planting compartments. Through the isolated and closed cultivation structure, the adverse effects of external bacteria, airflow, and temperature and humidity fluctuations on the growth of mushrooms are reduced, and independent cultivation and management in different zones are achieved.

[0083] The cultivation cabin is equipped with a plasma sterilizer, an ultrasonic humidity generator, an air-source heat pump, a carbon dioxide sensor, a humidity sensor, an oxygen sensor, and a mushroom-specific growth lamp. All of these electrical devices and detection components are electrically connected to the intelligent control system. The intelligent control system has a built-in linkage control module that collects environmental monitoring data from various sensors in real time and, based on built-in decision logic, controls the mushroom-specific growth lamp, plasma sterilizer, ultrasonic humidity generator, and air-source heat pump to start, stop, and adjust their power accordingly. This achieves automated, closed-loop, and high-precision control of the mushroom growth environment inside the cultivation cabin.

[0084] The bottom of the planting container is fixedly equipped with a mobile base. The mobile base adopts a high-strength load-bearing sliding structure, which enables the container to move freely, be flexibly transported, and be assembled. The layout and number of units can be flexibly adjusted according to the cultivation scale and site layout to meet the production needs of different planting volumes. This effectively solves the industry's technical defects of traditional fixed mushroom houses, such as solidified structure, immobility, difficulty in modification, high cost of large-scale expansion, and poor versatility.

[0085] The planting cabin is equipped with an insulation layer, preferably made of rigid polyurethane foam insulation board, with a thickness of not less than 50mm. The insulation layer is adhered and fixed to the inner wall of the cabin body, and the bonding surface is sealed, with no gaps or heat-permeable layers, thus preventing heat loss from inside the cabin and heat penetration from outside. In this embodiment, the overall thermal conductivity of the cabin is controlled at ≤0.024W / (m·K), possessing extremely low thermal conductivity, achieving efficient heat insulation, reducing the continuous operating load of the air source heat pump, and significantly reducing equipment energy consumption.

[0086] The plasma sterilizers are evenly installed at the top of the cabin using a distributed deployment method. Utilizing the principle of plasma ionization sterilization, they effectively disinfect the air and attached microorganisms within the cabin. The distributed deployment eliminates blind spots, achieving comprehensive sterilization without dead angles and continuously inhibiting the growth of miscellaneous bacteria, mold, and harmful microorganisms. Furthermore, this sterilization method is physical, requiring no chemical disinfectants, leaving no chemical residues, and will not cause phytotoxicity to the morel mycelium or fruiting bodies, ensuring the safety of mushroom growth.

[0087] The mist outlets of the ultrasonic humidity generator are evenly distributed in the container planting and cultivation area to ensure that the atomized water vapor is evenly diffused to every cultivation point in the container. The mist output of the ultrasonic humidity generator is continuously and steplessly adjusted by the intelligent control system. It can dynamically match the humidification power according to the real-time humidity difference, quickly balance the humidity environment in the container, and stably maintain the suitable humidity range for morel mushroom growth. The humidity control accuracy of this structure can reach ±3%RH.

[0088] The air source heat pump integrates cooling, heating, and ventilation functions, serving as the core temperature control and gas exchange equipment within the mushroom cabin. Receiving control commands from the intelligent control system, the air source heat pump adaptively adjusts its operating mode and output power based on real-time temperature monitoring data. The equipment has a temperature control range of 1-30℃ and a temperature control accuracy of ±0.5℃, precisely matching the differentiated temperature requirements of morel mushroom mycelium during its vegetative growth stage and fruiting body reproductive growth stage, thus conforming to the temperature control standards throughout the entire mushroom growth cycle.

[0089] The carbon dioxide, humidity, and oxygen sensors all utilize industrial-grade high-precision probes. These sensors are deployed at multiple points in a non-uniform, staggered arrangement within the upper, middle, and lower cultivation areas of the cabin. This allows for real-time collection of environmental parameters at different locations and heights within the cabin, avoiding the limitations and biases of single-point monitoring and improving the comprehensiveness and accuracy of environmental monitoring. The intelligent control system is equipped with an external touchscreen display terminal, allowing staff to manually set threshold values ​​for temperature, humidity, carbon dioxide concentration, and oxygen concentration for different growth stages of the morel mushrooms. The system integrates a data storage unit and an audible and visual alarm unit, providing real-time data storage, historical data review, and alarm functions for abnormal operating conditions. When sensor data exceeds preset threshold values, the system immediately triggers an audible and visual alarm signal and automatically drives the corresponding control equipment to perform correction actions, quickly returning the cabin environment to the preset standard range.

[0090] The following provides two specific implementation examples for planting modular units: 108 cubic meters and 720 cubic meters.

[0091] Example 1: Mushroom cultivation in a 108 cubic meter standard container This embodiment uses a 108m³ integrated standard planting container. A movable base is fixedly installed at the bottom of the container, enabling complete transport and rapid deployment, suitable for small to medium-sized cultivation sites. The inner walls of the container are fixedly adhered with 50mm thick rigid polyurethane foam insulation panels, with sealed seams to ensure no heat leakage. Three humidity sensors, two carbon dioxide sensors, and two oxygen sensors are evenly distributed throughout the container. Two plasma sterilizers are fixedly installed at the top of the container, and one ultrasonic humidity generator is symmetrically arranged on each side of the planting area. An air-source heat pump is installed at the end of the container. All equipment is connected to an intelligent control system.

[0092] The growth parameters of morel mushrooms are pre-entered and fixed by the intelligent control system: during the mycelial growth period, the temperature is controlled at 5-15℃, the humidity is controlled at 65-70%RH, and the carbon dioxide concentration is ≤1500ppm; during the fruiting body growth period, the temperature is controlled at 10-18℃, the humidity is controlled at 85-90%RH, and the carbon dioxide concentration is ≤1000ppm.

[0093] During system operation, real-time monitoring data from sensors at various points is collected. When the humidity inside the chamber falls below a preset threshold, the system automatically activates the ultrasonic humidity generator to compensate for humidification. When the temperature inside the chamber deviates from the set range, the air source heat pump automatically switches between cooling and heating modes for precise temperature adjustment. When the carbon dioxide concentration exceeds the standard, the system activates the forced ventilation mode in conjunction with the air source heat pump to replace the polluted air inside the chamber. The system automatically activates the plasma sterilizer according to a preset time cycle to complete the sterilization process inside the chamber. This embodiment operates entirely automatically without continuous manual intervention, ensuring a stable and controllable growth environment for morel mushrooms. Actual measurements show that the contamination rate of miscellaneous bacteria in this embodiment is less than 2%, and compared to traditional greenhouse cultivation methods, morel mushroom yield is increased by more than 15%.

[0094] Example 2: Mushroom cultivation in a 720 cubic meter large-scale container This embodiment adopts a modular assembly structure, consisting of six 108-cubic-meter standard modular units assembled to form a large integrated planting cabin with a total volume of 720m³. Elastic sealing and insulation strips are added to the joints of the modules to enhance the airtightness and heat insulation of the joints, preventing air and heat leaks and ensuring the overall airtight and heat-insulating performance of the cabin. Based on the large internal space of the cabin, multiple sets of high-precision environmental sensors are evenly distributed, and plasma sterilizers are installed throughout the entire area. Multiple high-flow-rate ultrasonic humidity generators and high-power air-source heat pumps are also installed. All modular equipment is connected to a single intelligent control system for centralized management.

[0095] This embodiment adopts the environmental parameter standards for the entire growth cycle of morel mushrooms. The intelligent control system enables synchronous linkage of multiple devices and independent and precise control of different zones, eliminating the problem of environmental stratification deviation within a large area of ​​the chamber. The overall environmental parameter deviation within the chamber is ≤±1%, fully meeting the requirements for standardized, batch, and intensive mass production of morel mushrooms. Comparative tests show that this large-scale modular container reduces overall energy consumption by more than 30% compared to traditional fixed mushroom houses. Intelligent control significantly reduces the amount of manual inspection and control work, reducing labor management costs by 50%, making it suitable for large-scale industrial cultivation applications.

[0096] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
