The existing seedling cultivation environments are mostly greenhouses and artificial stress-resistant environments.

[0004] The patent with the publication number CN215836152U discloses a stress resistance environment simulation device for high-quality corn seeds, including: a plurality of first humidity sensors, a plurality of second humidity sensors, a display, a dehumidifier, a dehumidifying exhaust fan, a dehumidifying intake fan, an electric control skylight, a driving motor, and a shed body; the shed body covers the simulation soil and is erected on the simulation soil; the electric control skylight is installed on the top surface of the shed body; the driving motor is drivingly connected to the electric control skylight, and the driving motor is installed on the upper part of the shed body; a plurality of first humidity sensors are arranged at intervals on the outer side wall of the upper part of the shed body; a plurality of second humidity sensors are arranged at intervals in the middle of the inner side wall of the shed body.

[0028] Embodiment:

[0029] As Figures 1 to 6 shown, the present invention provides a multi-variable gradient linkage seedling cultivation cabin 10, including: a seedling cultivation cabin 10, a transfer assembly 20, a bearing assembly 30, multiple stress assemblies 40, and multiple pneumatic partition devices 103. The main structure of the seedling cultivation cabin 10 is a seedling cultivation greenhouse, and tracks are arranged on both the top and bottom of the greenhouse to facilitate the operation of the transfer assembly 20; the plants are maintained in the first partition 101 in groups, and the bearing assembly 30 is a component with a fixed structure mainly composed of a cultivation tray, and the first preset direction is Figure 3In the X direction, the carrying components 30 are grouped in sets along a straight line in the same first preset direction, with each set containing multiple plant units to ensure the reliability of experimental data. The stress component 40 is mainly used to supplement and balance the conditions in the general environment, specifically including basic regulation of the humidity, temperature, and light composition of the air. Further, after separating each group of plant units with the pneumatic partition device 103, the variable data to be collected is adjusted, and long-term seedling cultivation is carried out. Specifically, it includes controlling and simulating the content of common active microorganisms in the air for testing disease resistance, simulating the humidity adjustment of air and soil for testing drought resistance, simulating the overall space temperature for testing cold resistance, and simulating the wind pressure in the independent space for testing lodging resistance. Specifically, the seedling cultivation chamber 10 conducts multi-variable simultaneous cultivation or separately controls and cultivates the numerical ladder of a single variable or combines the superposition states of multiple variables for each partition in the second partition 102 according to the specific experimental content, to explore the optimal maintenance environment for new plants. The transfer component 20 is a linear drive transfer system based on the bottom track system. The second preset direction is the Y direction, mainly used to control the position adjustment of the stress component 40, improve the position adjustment of the stress component 40 in the second partition 102, improve the precise control of the variables of each group of experimental data, and improve the reliability of the experimental data.

[0030] Further, as Figures 1 to 6 shown, the pneumatic partition device 103 includes: a mounting base 1031, a winder 1032, an air curtain 1033, an air pump 1034, and a plurality of suction attachments 1035. The mounting base 1031 is arranged on the top transfer component 20. The top transfer component 20 is mainly used for fine adjustment of the distance between the partition spaces to create a transition section between the two environmental chambers, to improve the reliability of the environmental change during the transfer of the plants. And by winding the air curtain 1033 between the two environmental chambers, the pre-mixing of the environment is realized, and then the stress component 40 supplements and balances the different environmental values of the environmental chambers, thereby improving the mixing speed of the environment. After the environment is stable, it is then transferred to the second partition 102.

[0031] Further, as Figures 1 to 6 shown, the suction attachment 1035 is specifically a magnetic sealing strip. The air curtain 1033 adsorbs to the suction attachments 1035 on the bottom surface, and a sealed space is formed between the plurality of air curtains 1033. And the air curtain 1033 is inflated to divide the temperature of the two separated chambers. Specifically, the suction attachments 1035 at the bottom can specifically use an electromagnetic component to control the fixation and separation of the air curtain 1033.

[0032] Further, as Figures 1 to 6As shown, the coercion component 40 includes: a temperature control unit, a lighting unit, a spray unit, and a wind unit. The wind unit is specifically composed of a plurality of centrifugal blowers. A corresponding wind unit is provided in each partition that needs to be subdivided in the second partition 102, which is used to mix air components and circulate air in the internal space of the seedling chamber 10. Correspondingly, a plurality of air ducts along the first preset direction are preset in the second partition 102, which are also used for detecting the ability to resist lodging; the temperature control unit is specifically a semiconductor refrigeration sheet and a carbon fiber heating film installed at the air outlet of the wind unit, which is used to cooperate with the wind unit to control the temperature of each independently controlled cabin, and to control the temperature of each small partition in the second partition 102 in different temperature intervals. The gradient data is controlled to facilitate the simulation of the gradient environment of a single variable to obtain the growth conditions, cold resistance and drought resistance under different temperatures; the lighting unit is specifically a full-spectrum LED lamp group, and the control component is used to optimize and adjust the light components, so as to unify the lighting conditions of the second partition 102 to simulate the stress conditions caused by different light qualities; the spray unit includes a high-pressure atomizing nozzle, which is matched with artificially simulated mixed materials with different concentrations of microorganisms to simulate the microbial components and corresponding concentrations in disease-prone areas, and the proportion is used to study the disease resistance of new plants through artificial control data.

[0033] Furthermore, if Figures 1 to 6 As shown, the second partition 102 is used to control various variables so as to create the cultivation environment required for the corresponding experiment. In the process of cultivating and breeding the recessive nuclear sterile three-line hybrid of semi-winter Brassica napus, multiple seedling chambers 10 are used to cultivate each single variable in different gradient environments, or two or more variables are superimposed to create a cultivation environment under multi-variable linkage.

[0034] Furthermore, if Figures 1 to 6 As shown, a PC control center for scheduling is set in the nursery cabin 10, which is used to cooperate with various sensors 402, including wind speed sensor 402, light intensity sensor 402, temperature sensor 402, and visual sensor 402, for identifying and monitoring wind speed, light composition and light intensity, temperature, and the growth and disease conditions of the plants themselves. The nursery cabin 10 can be reused in batches, and because the environmental data is highly customized, it is convenient to create various climates, greatly reducing the cultivation cycle required for experimental projects, and a harvesting observation room is set between the nursery cabins 10 to pick and collect the plants.

[0035] In summary, when using the multi-variable gradient linkage seedling cultivation chamber 10, through the linear drive track system installed at the top and bottom, the precise positioning and stable transfer of the bearing component 30 are realized, ensuring the orderly migration of plants among different environmental compartments, and effectively maintaining the continuity of experimental samples and the reliability of data; by linearly grouping the layout of the seedling trays and plants in the X direction, a unit grouping structure of plants is established to ensure the spatial isolation and data comparability between experimental groups, providing a basic carrier for multi-variable control experiments; through the dynamic sealing combination of the inflatable air curtain 1033 and the magnetic adsorption strip, combined with the adjustable spacing at the top to achieve the design of the transition compartment between different spaces, the flexible separation and pre-mixing functions of different environmental compartments are realized, which not only ensures the rapid switching of environmental parameters such as temperature and humidity, but also avoids the impact of sudden environmental changes on plants during the transfer process, improving the rigor of the experimental process; through the PC central control system to design experiments on multi-dimensional environmental parameters, supporting automated cultivation schemes for single-variable gradients, dual-variable intersections and multi-variable couplings, the breeding cycle of multi-resistant winter rape as a type of crop with margins is significantly shortened, and the reliability of experimental results and the convenience of breeding are further improved.

[0036] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope recorded in the present invention can easily think of changes or substitutions, which should all be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
