Description

Technical Field

[0001] The present invention relates to the field of soybean growth testing, and in particular to a soybean multi-ecological zone adaptability testing platform. Background Art

[0002] As an important food and cash crop, soybean variety selection and ecological adaptability research are crucial to agricultural production. Traditional soybean adaptability tests mostly rely on field trials in a single ecological zone, which has problems such as uncontrollable environmental parameters, long test cycles, and poor data repeatability. Although some artificial climate simulation devices have appeared in the prior art, their functional integration is low, making it difficult to achieve synchronous simulation and precise control of multiple ecological zones (such as different temperature, humidity, light, water, and soil conditions). For example, in terms of soil environment simulation, existing testing equipment usually uses planting troughs with a fixed depth, which cannot dynamically adjust the nutrient distribution and water infiltration rate in the root growth area; in terms of environmental control, the temperature control and lighting systems often operate independently, lacking a coordinated adjustment mechanism, resulting in low energy utilization and distorted environmental simulation. In addition, the irrigation and fertilization modules of traditional devices mostly adopt an open design, which is prone to waste of resources and cannot achieve targeted and quantitative supply, especially insufficient response to the differentiated needs of soybeans at different growth stages. When testing the impact of different soils on soybean growth, some people will directly transplant soybeans from one soil to another. The process of adapting to the new environment will affect the growth of soybeans, thus welcoming the test of soybean growth adaptability. Therefore, it is urgent to design a soybean multi-ecological zone adaptability test platform to solve the problem of testing the soybean growth environment. Summary of the Invention

[0003] The purpose of the present invention is to solve the deficiencies of the prior art and provide a soybean multi-ecological zone adaptability testing platform.

[0004] The present invention is achieved through the following technical solutions:

[0005] This technical solution relates to a soybean multi-ecological zone adaptability testing platform. Its core lies in its modular structure, enabling controllable simulation and dynamic adjustment of multiple environmental parameters. The platform consists of a symmetrical main frame consisting of a base box, uprights, and a top mounting base. A hydraulic cylinder drives a piston rod, which drives the connecting frame and storage box to form a liftable soil layer simulation unit. The bottom opening of the storage box, combined with a film seal, blocks the soil, allowing for easy replacement of the soil inside. The environmental control module includes a material pump system, a rotary temperature and light assembly, and an intelligent irrigation unit. Rotating covers with illumination lamps and water spray boxes are located at the lower ends of the two uprights, respectively. The water pump and nozzles provide targeted humidification. A built-in heating wire network, combined with a network of uprights and inserts, regulates the temperature gradient in the root zone. A pulley drive system is installed on the support plate to control the rotation of the inserts, allowing for the filling and replacement of soil in the storage box. The platform allows for the replacement of soybean growing soil, and combined with humidity and temperature control, allows for testing soybean growth adaptability.

[0006] Compared with the prior art, the present invention has the following beneficial effects:

[0007] The present invention adopts a phased and progressive soil replacement strategy. When replacing the test soil, 50% of the soil layer in the storage box is replaced first, and the other half of the original soil is retained to form a transition adaptation zone with the soybean root system, effectively simulating the gradual soil change process in the natural environment. This design avoids the root stress damage or growth stagnation caused by the traditional one-time full soil replacement. The sealing film is used to control the opening sequence of the through holes, so that the nutrients in the new soil gradually penetrate and mix with the original soil, which not only ensures that the soybean maintains basal metabolic activity during the adaptation period, but also accurately reveals the stage-by-stage influence mechanism of different soil physical and chemical properties on soybeans by comparing the differentiated growth morphology (such as root length, fibrous root density) and physiological indicators (such as ion absorption efficiency, enzyme activity) of the roots at the interface between the new and old soils. In addition, combined with the layered irrigation of the intubation group and the heat conduction of the temperature control plate, the local temperature and humidity gradient can be synchronously controlled in the semi-replaced soil, further distinguishing the adaptability differences under the coupling of soil type and external environment, significantly improving the resolution and reliability of the test data, and providing a scientific basis for screening widely adaptable soybean varieties and optimizing soil improvement programs. The present invention realizes the gradual replacement of soil in a storage box in stages by inserting pipes at different heights, simulating the process of soil gradual change, thereby facilitating the test of the adaptability of soybean growth.
