Description

Technical Field

[0001] This invention relates to the field of sweet potato cultivation technology, and in particular to a sweet potato cultivation experimental device. Background Technology

[0002] As an important food and economic crop, the yield and quality of sweet potato are affected by a variety of environmental factors, among which water conditions are one of the key factors determining the growth and development of sweet potato and the accumulation of its internal substances (such as starch).

[0003] Currently, experiments on sweet potato water utilization in cultivation and seedling raising largely rely on traditional soil or substrate culture systems. These systems struggle to finely regulate different water gradients, leading to significant fluctuations in water conditions and impacting data accuracy and repeatability. Furthermore, uneven water distribution within the soil or substrate creates a complex and variable environment for the sweet potato root system, making it difficult to clearly define the singular physiological effects of water. Additionally, existing devices often rely on manual measurement of water content, which is not only labor-intensive but also involves retrospective and intermittent measurements. This lack of real-time, in-situ, and continuous dynamic water monitoring limits in-depth research into the impact of dynamic water changes on sweet potato growth and hinders a deeper understanding of the effects of water on sweet potato seedling raising and starch quality formation.

[0039] For example, in one embodiment: the top surface of the transplant placement slide plate 13 is recessed with multiple leakage holes, and one end of the main humidifier 21 is provided with a main humidification inlet, which is connected to the sweet potato culture medium storage tank through a pipe. The bottom of the inner wall of each secondary regulating pipe 41 is recessed with secondary spray holes at intervals along its length. The bottom ends of two lower scissor lifters 33 are respectively fitted with lower synchronous transmission belts to achieve synchronous transmission, and the bottom ends of two upper scissor lifters 36 are respectively fitted with upper synchronous transmission belts to achieve synchronous transmission. A partition plate 341 is located between the first secondary humidity regulating tank 411 and the second secondary humidity regulating tank 412. A pressure pump is provided on the sweet potato culture medium storage tank, and the pressure pump is rotatably connected to the end of multiple humidity regulating components 40 away from the secondary humidity rotating motor through a hose. The middle of the outer wall of the inner regulating pipe body 431 is slidably installed on the inner wall of the communicating cavity 428 away from the humidity regulating motor 423. The cultivation isolation tray 34 is equipped with an array of multiple TDR (Time Domain Reflectometry) soil moisture sensors, which are respectively set in multiple cultivation chambers to monitor and record the dynamic changes in soil volumetric water content in real time. It is linked with the humidification circulation component 20, multiple humidity adjustment components 40 and sweet potato culture solution storage tank to achieve closed-loop control and stabilize the moisture at the set value.

[0040] For example, in one embodiment: when sweet potatoes need to be cultivated, sweet potatoes are placed in multiple cultivation isolation trays 34. These trays 34 are then spaced apart along their length on a cultivation base 31 and a second-layer cultivation rack 32. The main humidifier and thermostat 21 is then activated to draw sweet potato culture solution from the sweet potato culture solution storage tank and evenly spray it onto the cultivation regulating rack 30 below for uniform irrigation. Furthermore, when the moisture sensor installed in the cultivation isolation tray 34 detects a moisture difference between the multiple cultivation chambers, the pressure pump on the sweet potato culture solution storage tank is activated and delivers supplementary water flow through a hose to the humidity regulating component 40 of the adjacent cultivation chamber with the moisture difference. This supplementary water flow is then transported along multiple secondary regulating pipes 41 and multiple humidity regulating elements 42.

[0041] When it is necessary to humidify all of the individual culture isolation trays 34, the humidity regulating motor 423 will be activated, driving the movable regulating shaft 424 to move the regulating inner cylinder 425 to the center position between the first auxiliary humidity regulating tank 411 and the second auxiliary humidity regulating tank 412. This allows the supplementary water flow entering from the connecting inner shell 422 to flow out through the space between the internal cavity of the connecting inner shell 422, the connecting cavity 428, the multiple connecting liquid holes 435, and the multiple arc-shaped sliders 446 to another auxiliary regulating pipe 41. When the supplementary water flow flows into the middle of the connecting cavity 428, since the regulating inner cylinder 425 is now at the center position between the first auxiliary humidity regulating tank 411 and the second auxiliary humidity regulating tank 412, the opening degree of the multiple first auxiliary humidity regulating tanks 411 and the multiple second auxiliary humidity regulating tanks 412 is the same, thereby allowing the supplementary water flow out from them to synchronously supplement and transport the culture chamber below. Simultaneously, the secondary humidity motor will start, driving the humidity regulating component 40 to rotate slowly, ensuring that the supplementary water flow is sprayed evenly and that the supplementary irrigation is uniform. When moisture differences occur between adjacent culture chambers of a single culture isolation tray 34, the position of the regulating inner cylinder 425 can be adjusted, thereby adjusting the opening degree of multiple first secondary humidity regulating slots 411 and multiple second secondary humidity regulating slots 412, and thus regulating the flow rate of the sprayed supplementary water.

[0042] When a significant difference in moisture content occurs in a culture chamber of a single culture isolation tray 34, requiring focused water replenishment, the humidity regulating motor 423 will push the regulating inner cylinder 425 to move away from the humidity regulating motor 423 until one end of the regulating inner cylinder 425 abuts against the inner regulating tube 431 and the compression regulating slide cylinder 441. Since the middle of the outer wall of the inner regulating tube 431 is slidably mounted on the inner wall of the communicating cavity 428 away from the humidity regulating motor 423, and the end of the inner regulating tube 431 away from the humidity regulating motor 423 is made of elastic material, when the humidity... When the regulating motor 423 continues to push, the end of the inner regulating tube 431 away from the humidity regulating motor 423 will deform inward, and push the compression regulating slide 441 to slide. The third spring 444 is compressed until one end of the compression regulating slide 441 abuts against the inner wall of the mounting slip ring 445, and the inner wall of the end of the inner regulating tube 431 away from the humidity regulating motor 423 abuts against the outer wall of the compression regulating slide 441, thus sealing off the supplementary water flow. This allows the supplementary water flow to flow out of multiple second liquid channels 434, quickly replenishing the water in the culture chamber that is deficient in moisture.

[0043] For example, in one embodiment: each culture chamber is provided with a cultivation substrate, which consists of 4 parts peat moss, 3 parts perlite and 3 parts vermiculite, to ensure that the total porosity of the cultivation substrate is uniform, so as to prevent waterlogging and oxygen deficiency.

[0044] A temperature sensor is installed inside the hollow cavity 11, and the distance between the cultivation base 31, the second-layer cultivation rack 32 and the top light rack 38 can be adjusted by two lifting drive motors 37 to adjust the light intensity and ventilation of the sweet potatoes on the cultivation isolation plate 34.

[0045] For example, in one embodiment: the sweet potato culture medium may be a mixture of fertilizer and purified water, or a mixture of purified water alone, or a mixture of heavy metals, purified water, and fertilizer.
