Description

Technical Field

[0001] This utility model relates to the field of cultivation device technology, specifically a dry-earth simulation gradient water cultivation device adapted to a lifting water storage chassis. Background Technology

[0002] Lanzhou lily (Lilium davidii var. unicolor) is a perennial herbaceous bulbous plant belonging to the genus Lilium in the family Liliaceae. It is a variety of Sichuan lily and the only sweet lily used for both medicinal and edible purposes. Its bulbs are large, pure white, and have a delicate texture, making it highly valuable in terms of edibility, medicinal properties, and ornamental value. Lanzhou lily is mainly cultivated on hillsides without irrigation, and drought is the primary factor limiting its yield and quality. The cultivation of Lanzhou lily is a dryland farming method without irrigation. However, the main producing areas experience low rainfall and uneven spatial and temporal distribution. This traditional, un-irrigated production method results in slow weight gain and reduced yield (bulb weight), hindering the sustainable development of the lily industry. Researching the physiological, biochemical, and molecular mechanisms of Lanzhou lily under drought stress is of significant guiding importance for the breeding of drought-resistant new varieties and the regulation of water and fertilizer in lily cultivation.

[0003] Existing drought simulation cultivation devices have significant limitations: First, the precision of water gradient control is insufficient, relying heavily on manual watering or fixed water storage structures, making it difficult to achieve continuous gradient adjustment, and the water consistency in parallel experiments is poor; second, they are not well adapted to the growth characteristics of Lanzhou lilies, and the unreasonable fixing method of the cultivation containers easily leads to problems such as root hypoxia and soil loss, affecting the authenticity of the experiment; third, operation and monitoring are inconvenient, lacking integrated lifting and lowering adjustment, real-time monitoring, and moving structures, resulting in cumbersome experimental procedures and large data errors; fourth, the ability to conduct multiple parallel experiments is insufficient, making it difficult to conduct comparative studies of different drought gradients simultaneously, resulting in low experimental efficiency.

[0004] To address the aforementioned issues, there is an urgent need to develop a specialized culture device that features controllable gradients, high adaptability, and convenient operation, in order to meet the stringent experimental requirements for research on the drought resistance mechanism of Lanzhou lily.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 This utility model provides a technical solution: In this technical solution, the dry-earth simulation gradient water culture device adapted to the lifting water storage chassis includes an adapter base 1. The top of the adapter base 1 is equipped with a lifting chassis 8, the upper end of the lifting chassis 8 is equipped with a water storage box 7, and the upper end of the water storage box 7 is equipped with a culture plate 4. The upper end of the culture plate 4 has six evenly spaced circular holes 5. Each circular hole 5 is equipped with a lily culture pot 6. The top of the lily culture pot 6 is equipped with a limiting ring 18, which is fitted to the culture plate 4. The lifting chassis 8 and the adapter base 1 are hinged on the left and right sides with hinge rods a12 and b13. Both ends of the hinge rods a12 and b13 are equipped with hinge seats 11. One end of the hinge seat 11 is connected to the lifting chassis 8, and the other end of the hinge seat 11 is connected to the adapter base 1.

[0020] In the specific implementation process, the adapter base 1 is made of high-strength aluminum alloy, with an overall rectangular structure. The bottom has pre-drilled holes for drive wheels, and the top surface is treated with an anti-slip coating to ensure the lifting base 8 is placed stably and without displacement. The lifting base 8 is made of lightweight stainless steel and fits perfectly against the bottom of the water storage box 7, secured with bolts. A waterproof sealing gasket is added at the connection point to prevent water leakage from the water storage box 7 to the hinge structure, causing corrosion. The water storage box 7 is made of food-grade PP material with a smooth inner wall without dead corners, facilitating cleaning and water changes. Its dimensions perfectly match the culture plate 4, ensuring that all six lily cultivation pots 6 are evenly in contact with the water storage area, guaranteeing a consistent water supply. The culture plate 4 is made of rigid PVC material, with six round holes 5 whose diameters precisely match the outer diameter of the lily cultivation pots 6, preventing the pots from shaking. The edges of the round holes are chamfered to prevent scratching the outer wall of the cultivation pots during installation. The volume of the lily cultivation pot 6 is adapted to the root growth needs of Lanzhou lily plants; the limiting ring 18 is made of annular ABS material, with an outer diameter larger than the diameter of the round hole 5, which can completely cover the gap of the round hole when it is attached to the upper surface of the cultivation plate 4, preventing debris from falling into the water storage box 7. The hinge rods a12 and b13 are both made of stainless steel and adopt a cross-hinged method (similar to a scissor structure). The hinge seats 11 at both ends have built-in wear-resistant bearings to ensure that there is no jamming during the lifting process; the hinge seats 11 are fixed to the preset installation positions of the adapter base 1 and the lifting chassis 8 by welding, and the weld is treated with anti-rust to extend the service life.

[0021] In some technical solutions, an adjustment frame 14 is installed at the top of the adapter base 1 at the bottom of the hinge rod a12. An adjustment slide 15 is provided on the inner wall of the adjustment frame 14. An adjustment wheel 16 is installed on the side wall of the hinge seat 11 at the bottom of the hinge rod a12. The adjustment wheel 16 is installed in the adjustment slide 15.

[0022] In the specific implementation process, the adjustment frame 14 is a U-shaped steel structure, which is vertically fixed to the corresponding position at the top of the adapter base 1 by expansion bolts. Its opening faces the hinge rod a12, and its inner wall is aligned with the adjustment wheel 16, ensuring that the adjustment wheel 16 only slides horizontally along the adjustment slide 15 and avoids deviation. The adjustment slide 15 is a rectangular groove structure with a polytetrafluoroethylene coating on the inner wall to reduce the friction when the adjustment wheel 16 slides and improve the adjustment accuracy. Limiting blocks are set at both ends of the slide to prevent the adjustment wheel from sliding off the track. The adjustment wheel 16 is made of polyurethane and is fixed to the hinge seat 11 at the bottom of the hinge rod a12 by a rotating shaft. A dustproof sealing ring is installed between the rotating shaft and the wheel body to prevent soil debris or water from entering and affecting the rotation flexibility.

[0023] In some technical solutions, the inner wall of the adjusting slide 15 is provided with three adjustment scale lines.

[0024] In the specific implementation process, the three adjustment scale lines are evenly distributed along the length of the adjustment slide 15 and are marked as "Scale 1", "Scale 2" and "Scale 3" respectively, corresponding to the three fixed height levels of the lifting chassis 8.

[0025] In some technical solutions, an electric push rod 17 is installed between the hinge rod b13 and the adapter base 1. One end of the electric push rod 17 is hinged to the side wall of the hinge rod b13, and the other end of the electric push rod 17 is hinged to the adapter base 1.

[0026] In practical implementation, the electric push rod 17 is a DC geared electric push rod. The hinges at both ends of the electric push rod 17 adopt a universal hinge structure, which can adapt to the angle changes during the lifting and lowering of the hinge rod b13 and avoid jamming due to force. Lubricating grease is added to the hinge parts, and regular maintenance can extend the service life. The hinge point between the electric push rod 17 and the matching base 1 is located on the inner side of the central axis of the base, ensuring that the thrust is evenly applied to the hinge rod b13, so that the lifting platform 8 is raised and lowered synchronously on both sides and avoids tilting.

[0027] In some technical solutions, the bottom ends of the limiting ring 18 are equipped with locking blocks 20 on both sides, and the top of the culture plate 4 is provided with locking grooves 19 on both sides of the round hole 5. The locking blocks 20 are locked in the locking grooves 19. The two side walls of the locking blocks 20 are provided with inclined convex surfaces 21, and the two side walls of the locking grooves 19 are provided with inclined concave surfaces 22. The inclined convex surfaces 21 and the inclined concave surfaces 22 cooperate with each other.

[0028] In the specific implementation process, the locking block 20 is made of elastic plastic and is integrally formed with the limiting ring 18 through injection molding. It has a certain elastic deformation capability, which facilitates locking and disassembly. The inclined concave surface 22 and the inclined convex surface 21 are completely fitted together. When locking, the locking block 20 is automatically embedded into the locking groove 19 by the inclined force, without the need for additional fasteners. When disassembling, simply lift the limiting ring 18 upwards, and the inclined convex surface will deform under force to disengage from the locking groove, making the operation convenient.

[0029] In some technical solutions, a support plate 2 is vertically installed on the front top of the adapter base 1, the culture plate 4 is connected to the side wall of the support plate 2, a display screen 3 is installed on the top of the support plate 2, drive wheels 10 are installed at the four corners of the bottom of the adapter base 1, and push rods 9 are installed on the rear side wall of the adapter base 1.

[0030] In the specific implementation process, the support plate 2 is a welded stainless steel square tube structure, with its bottom welded and fixed to the adapter base 1, and its top connected to the display screen 3 by bolts. The inner side of the support plate 2 has pre-drilled wire holes to hide the connection lines between the sensor and the display screen, preventing tangling or damage. The display screen 3 is a touch-screen LCD display, which can display soil moisture data corresponding to the six lily cultivation pots 6 in sections, supporting real-time data refresh, historical data query and export, and labeling each cultivation pot with its number for easy recording of corresponding gradients. The drive wheels 10 are universal wheels with braking function, installed in the pre-drilled holes at the four corners of the bottom of the adapter base 1. When braking, the wheels can be fixed by stepping on the brake pedal to prevent the device from moving during the experiment. The wheels are made of rubber, are quiet and wear-resistant, and suitable for laboratory floor environments. The push rod 9 is made of round tubular stainless steel.

[0031] In some technical solutions, a soil moisture sensor is installed inside the lily cultivation pot 6, and the lily cultivation pot 6 is made of transparent material.

[0032] In the specific implementation process, a frequency domain reflectance (FDR) soil moisture sensor was selected, with a measurement range of 0-100% vol and a measurement accuracy of ±2%. The probe length was 8 cm, installed on the inner side wall of the lily cultivation pot 6 (2 cm from the pot wall and 5 cm from the bottom of the pot). The probe surface was treated with an anti-corrosion coating to prevent rusting from direct contact with the soil. The sensor was connected to the control module in the support plate 2 via a wire passing through a pre-reserved waterproof hole in the side wall of the cultivation pot (the hole was sealed with a plug), and then the data was transmitted to the display screen 3. This ensured stable data transmission and prevented water from seeping into the sensor interface and causing a short circuit. The lily cultivation pot 6 was made of high-transparency PC material (light transmittance ≥90%), which is resistant to acid and alkali corrosion and can withstand long-term contact with soil without deformation. The transparent material allows researchers to directly observe the growth status of the Lanzhou lily roots (such as root length and number of branches) and the distribution of soil moisture, while not affecting the appearance observation of the waxy layer of the leaves (observation can be aided by an external light source).

[0033] Work Process: Preliminary Preparation: Fill six transparent lily cultivation pots with native Lanzhou lily substrate, plant lily seedlings of uniform growth, and fix the cultivation pots in the round holes by the engagement of the retaining ring's locking block with the convex surface of the cultivation plate's slot. Pour a measured amount of clean water into the water storage box, ensuring the water level evenly covers the bottom area of ​​the box.

[0034] Gradient setting: Activate the electric push rod via the control button to drive the hinge rods a and b in tandem, causing the adjusting wheel to slide along the adjusting track. According to experimental requirements, align the adjusting wheel with the corresponding scale line to achieve precise positioning of the lifting chassis, forming gradients of mild drought, moderate drought, and severe drought (scale 3 represents the near-water end, and scale 1 represents the far-water end).

[0035] Cultivation and Monitoring: The lily cultivation pots absorb water from the water storage box through drainage holes at the bottom. Different heights correspond to different water absorption intensities, maintaining a gradient moisture environment. Soil moisture sensors collect humidity data from each pot in real time, which is transmitted to a display screen via the control module. Experimenters can visually view the data and observe root growth and the state of the leaf wax layer through the transparent cultivation pots.

[0036] Routine maintenance: Regularly check the water level in the storage tank via the display screen and replenish water promptly to ensure gradient stability; when gradient adjustment is needed, simply repeat the gradient setting steps. Use the drive wheels and push rod to move the experimental position as required. After the experiment, disassemble the cleaning device for the culture pot.
