DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of this application clearer, the technical solution in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0025] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features; in the description of this application, unless otherwise specified, the meaning of "plurality" is three or more.

[0026] Figure 1-Figure 5 A corn seed breeding and seedling raising device provided in an embodiment of the present application includes: a cultivation box 1, wherein the cultivation box 1 is divided into a plurality of cavities by an isolation plate 2, a pull-out assembly 3 is movably arranged in the cavity, and the pull-out assembly 3 includes a cultivation layer 31 and a uniform liquid supply layer 32 movably arranged in the cavity, guide rails 33 are arranged on the cultivation layer 31 and the uniform liquid supply layer 32, and the guide rails 33 are movably arranged in the cavity, and end plates 34 are fixed to the front ends of the cultivation layer 31 and the uniform liquid supply layer 32, the cultivation layer 31 is divided into a plurality of liquid inlet areas and a plurality of liquid immersion areas by the transverse partitions 313 and the longitudinal partitions 314, and the uniform liquid supply layer 32 is divided into a plurality of uniform liquid areas by the partition plates 322.

[0027] Based on the above technical scheme, when it is only necessary to simulate that the amount of water or the quality of nutrients in each layer of the pull-out component 3 is the same, the amount of water or the quality of nutrients injected into the liquid inlet area is controlled to remain consistent, and the water or nutrients in the liquid inlet area enter the uniform liquid layer, and the water or nutrients enter the immersion area again; when it is only necessary to simulate that the amount of water or the quality of nutrients in a single-layer pull-out component 3 is different, the amount of water or the quality of nutrients injected into the liquid inlet area is controlled to have a gradient difference, such as from none to excess or from a small amount to excess. When there is no water, a drought environment can be simulated, and when there is excess water, a waterlogged environment can be simulated, etc., and the water or nutrients in the liquid inlet area enter the uniform liquid layer, and the water or nutrients enter the immersion area again; in addition, the addition of different types of nutrients in the simulated single-layer pull-out component 3 can also be controlled.

[0028] On the basis of the above technical scheme, at least three corn seeds are planted in a single immersion area, so that there is a control group under the same conditions in each immersion area, which reduces the interference of irrelevant variables, makes the experimental results more reliable, and enhances the repeatability of the experiment; in addition, different amounts of water or different amounts of nutrients are supplied in the single-layer pull-out component 3, and different nutrients can be added to the immersion area in a simulated manner to simulate different growth environments of corn seeds, so as to effectively evaluate the adaptability and stress resistance of different corn varieties or in different environments, and provide a basis for the regional layout of varieties.

[0029] In a possible implementation, the cultivation layer 31 includes a square frame 311 fixed to the rear side of the end plate 34, a permeable plate 312 is fixedly arranged at the bottom of the square frame 311, a plurality of evenly distributed transverse partitions 313 and a single longitudinal partition 314 are fixedly arranged on the permeable plate 312, a plurality of immersion holes 315 are distributed in an array on the left side of the longitudinal partition 314 and the permeable plate 312 surrounded by the square frame 311 and the transverse partition 313, and a plurality of liquid distribution holes 316 are distributed in an array on the right side of the longitudinal partition 314 and the permeable plate 312 surrounded by the square frame 311 and the transverse partition 313.

[0030] By adopting the above technical solution, the water or nutrients in the liquid inlet area can enter the corresponding liquid homogenizing area through the liquid distribution hole 316, and the water or nutrients in the liquid homogenizing area can enter the corresponding liquid immersion area through the liquid immersion hole 315.

[0031] In one possible implementation, the uniform liquid supply layer 32 includes a square base frame 321 fixedly arranged on the rear side of the end plate 34 and the lower end of the cultivation layer 31, and a plurality of evenly distributed partition plates 322 are fixedly arranged on the square base frame 321. After water or nutrients enter each uniform liquid layer, the liquid level rises, thereby entering the immersion area through the immersion hole 315, so that the liquid level entering the immersion area from left to right in a single uniform liquid area can be kept consistent, thereby making the growth conditions of the corn seeds in a single immersion area consistent, which is beneficial to adding a control group experiment under the same group conditions.

[0032] In a possible implementation, the partition plate 322 and the transverse partition plate 313 are arranged correspondingly, so that the amount or type of water or nutrients from the liquid inlet area to the liquid homogenizing area and then to the immersion area maintains effective regional division.

[0033] In a possible implementation, the isolation plate 2 includes a base layer 21 fixedly arranged in the incubator 1, a liquid inlet channel 22 is provided in the base layer 21, and a plurality of liquid dispensing ports 23 are respectively provided on the liquid inlet channel 22, and the liquid dispensing ports 23 are connected with sealing plugs 25 through springs 24, and the sealing plugs 25 can move in the liquid dispensing ports 23 by the extension and contraction of the springs 24, so that the sealing plugs 25 can open or close the liquid dispensing ports 23, and the base layer 21 is fixedly provided with extension and contraction springs on both sides. The telescopic cylinder 26 has an output end hinged with an adjusting frame 27, and a plurality of liquid dispensing grooves 28 are provided on the adjusting frame 27 located at the lower end of the liquid dispensing port 23. A top plug 29 is fixedly provided at the center of the liquid dispensing groove 28. The top plug 29 is arranged corresponding to the sealing plug 25, and a liquid separation channel 210 is provided in the liquid dispensing groove 28 away from the top plug 29. The displacement distance of the top plug 29 in the vertical direction can be controlled by the different telescopic amounts of the telescopic cylinders 26 on both sides.

[0034] In a possible implementation, the liquid distribution port 23 is disposed corresponding to the liquid inlet area, which is beneficial for controlling the injection of equal or stepped amounts of water or nutrients and different types of nutrients into the liquid separation area.

[0035] In one possible implementation, the sealing plug 25 is a spherical structure, and can block the liquid dispensing port 23 when the sealing plug 25 is not moving. When the top plug block 29 moves upward, the sealing plug 25 can control the opening and closing amount of the liquid dispensing port 23 according to the displacement of the top plug block 29, thereby controlling the injection amount of water or nutrients.

[0036] When the above technical solution is used to simulate and control the moisture content in each layer of the drawer assembly 3, it is divided into the following two situations:

[0037] a. When it is only necessary to simulate that the amount of water in each layer of the drawing assembly 3 is the same, the contraction amount of the telescopic cylinders 26 on both sides is controlled to be equal, the top plug 29 moves upward, the rising distance of the sealing plug 25 remains consistent, the liquid dispensing ports 23 are all opened, and water enters the liquid separation channel 210 along the liquid dispensing ports 23, the water in the liquid separation channel 210 enters the liquid inlet area, and the water in the liquid inlet area enters the uniform liquid layer along the liquid dispensing holes 316, and then the water enters the immersion area along the immersion holes 315;

[0038] b. When it is only necessary to simulate the different water amounts in a single-layer drawing component 3, the difference in the contraction amount of the telescopic cylinders 26 on both sides is controlled to be relatively large, the top plug 29 moves upward, and the rising distance of the sealing plug 25 has a gradient difference. The liquid dispensing ports 23 are all opened with different opening and closing amounts, thereby simulating the state of water from zero to excess. The water enters the liquid separation channel 210 along the liquid dispensing port 23, the water in the liquid separation channel 210 enters the liquid inlet area, and the water in the liquid inlet area enters the uniform liquid layer along the liquid dispensing hole 316, and then the water enters the immersion area along the immersion hole 315;

[0039] When the amount of nutrients in each layer of the simulated drawer assembly 3 needs to be controlled, it is divided into the following three situations:

[0040] a. When it is only necessary to simulate that the nutrients in each layer of the pull-out assembly 3 have the same mass, the retracted amounts of the telescopic cylinders 26 on both sides are controlled to be equal, the top plug 29 moves upward, the rising distance of the sealing plug 25 remains consistent, the liquid dispensing ports 23 are all opened, and the nutrients enter the liquid separation channel 210 along the liquid dispensing ports 23, the nutrients in the liquid separation channel 210 enter the liquid inlet area, and the nutrients in the liquid inlet area enter the uniform liquid layer along the liquid dispensing holes 316, and then the nutrients enter the immersion area along the immersion holes 315;

[0041] b. When it is only necessary to simulate the different qualities of nutrients in a single-layer pull-out assembly 3, the difference in the contraction amounts of the telescopic cylinders 26 on both sides is controlled to be large, the top plug 29 moves upward, and a gradient difference appears in the rising distance of the sealing plug 25. The liquid dispensing ports 23 are all opened and the opening and closing amounts are different, thereby simulating a state where nutrients go from zero to excess. The nutrients enter the liquid separation channel 210 along the liquid dispensing ports 23, the nutrients in the liquid separation channel 210 enter the liquid inlet area, and the nutrients in the liquid inlet area enter the uniform liquid layer along the liquid dispensing holes 316, and the nutrients then enter the immersion area along the immersion holes 315.

[0042] c. On the basis of the above steps, when it is necessary to simulate that the types of nutrients in a single immersion area in a single-layer pull-out assembly 3 are different, the telescopic cylinder 26 on one side is controlled to shrink smaller, and the telescopic cylinder 26 on the other side is controlled to shrink larger, the top plug block 29 on the other side moves upward, the corresponding liquid distribution port 23 is opened, and the other liquid distribution ports 23 are closed. In addition, other conditions of the immersion layer in the upper and lower pull-out assemblies 3 remain consistent, and only the types of nutrients added in the corresponding immersion area are controlled to be different, thereby simulating that the types of nutrients injected into a single immersion area are different.

[0043] In one possible implementation, the isolation plate 2 is provided with a light simulation unit, which can simulate different light intensities and light times, so that during the rice seed breeding and seedling cultivation process, the normal conditions of corn seeds can be compared through different light intensities and light times, and corn varieties with sensitivity and adaptability to light under the conditions in the geographical environment can be selected and bred in a targeted manner.

[0044] Working principle:

[0045] First determine the variables that need to be controlled for each layer of the drawer assembly 3. When only the light intensity in each layer of the drawer assembly 3 needs to be simulated to be different, the light intensity of the light simulation unit in the drawer assembly 3 is controlled to be set in steps, while other conditions of the drawer assembly 3 are the same; when only the light exposure time in each layer of the drawer assembly 3 needs to be simulated to be different, the light exposure time in the drawer assembly 3 is controlled to be set in steps, while other conditions of the drawer assembly 3 are the same; when only the water volume in a single layer of the drawer assembly 3 needs to be simulated to be different, the difference in the contraction amount of the telescopic cylinder 26 on both sides is controlled to be large. , the water in the liquid inlet area enters the uniform liquid layer along the liquid distribution hole 316, and then enters the immersion area along the immersion hole 315, while other conditions of the pulling component 3 remain consistent; when it is only necessary to simulate the different quality or type of nutrients in the single-layer pulling component 3, the contraction amounts of the telescopic cylinders 26 on both sides are controlled to be different, and the nutrients in the liquid inlet area enter the uniform liquid layer along the liquid distribution hole 316, and then enter the immersion area along the immersion hole 315, while other conditions of the pulling component 3 remain consistent; when it is necessary to control the changes of two groups of variables, the above steps can be combined in pairs.

[0046] The above embodiments are only used to illustrate the technical solution of the present application, but not to limit it. The present application is not limited to the exact structure described above and illustrated in the accompanying drawings, and it cannot be determined that the specific implementation of the present application is limited to these descriptions. For ordinary technicians in the technical field to which the present application belongs, various changes and modifications made without departing from the concept of the present application should be deemed to belong to the protection scope of the present application.
