[0030] See Figures 1 to 2 as shown in

[0031] An integrated device for seed vigor detection modeling of the present invention, the integrated device includes:

[0032] A seed germination box 1, arranged in an m×n column grid, and each grid is provided with a groove 1-1 for accommodating seeds and capable of arranging and positioning the seeds;

[0033] A near-infrared seed vigor measuring instrument 2, which can emit light from above the seeds to penetrate the seeds and receive the optical signal from below the seeds to form spectral data;

[0034] A first conveyor mechanism 4, capable of conveying the seed germination box 1 from the starting position to the near-infrared seed vigor measuring instrument 2;

[0035] A seed germination and phenotype measurement unit 3, used for seed germination and recording the germination phenotype;

[0036] The integrated device further includes:

[0037] A second conveyor mechanism 5, capable of conveying the seed germination box 1 to the seed germination and phenotype measurement unit 3;

[0038] A data processing unit 6, which can store and analyze the seed germination phenotype data and the spectral data detected by the near-infrared seed vigor measuring instrument 2 in one-to-one correspondence, and by establishing a mathematical model, find the correlation between the spectral characteristics and the seed germination ability, so as to construct a seed vigor judgment model.

[0039] As a further introduction of this embodiment, a circular hole 1-2 with a diameter of 2-5 mm is provided below the groove 1-1, allowing the optical signal passing through the seeds to pass through and be received by the lower part.

[0040] As a further introduction of this embodiment, the near-infrared seed vigor measuring instrument 2 includes a laser light source 2-1 for emitting laser light to penetrate the seeds in the groove 1-1.

[0041] A spectral detection instrument 2-2 receives the optical signal through the circular hole 1-2 and converts it into spectral data.

[0042] As a further introduction of this embodiment, the seed germination and phenotype measurement unit 3 includes a water tank 3-1. The water in the water tank 3-1 enters the groove 1-1 through the circular hole 1-2 to provide a germination environment for the seeds.

[0043] A camera 3-2 is signal-connected to the data processing unit 6. The camera 3-2 can take pictures of the seed germination situation at a preset time interval and record the germination phenotype of the seeds and feedback it to the data processing unit 6.

[0044] The present invention proposes two implementation schemes as follows:

[0045] Implementation scheme 1: Detection and modeling of soybean seed vigor

[0046] Prepare an appropriate amount of soybean seeds and evenly scatter them on the seed germination box 1 with an 8×12 grid. By mechanically shaking the seed germination box 1, the soybean seeds fall into the grooves 1-1 in each grid to complete the seed arrangement. The seeds not arranged in the grooves 1-1 are allowed to fall naturally by tilting. Carefully check each groove 1-1 to ensure that there is exactly one soybean seed in each of them.

[0047] Start the first transfer mechanism 4 to transfer the seed germination box 1 with the arranged soybean seeds to the detection part of the near-infrared seed vigor measuring instrument 2. The laser light source 2-1 emits laser light in a specific wavelength range (such as 800-2500 nm) and irradiates the soybean seeds. The laser signal passing through the seeds passes through the circular hole 1-2 below the groove 1-1 on the seed germination box 1 and is received by the spectral detector 2-2. The spectral detector 2-2 converts the received optical signal into spectral data and transmits it to the data processing unit 6 for storage.

[0048] The second transfer mechanism 5 transfers the seed germination box 1 that has completed the vigor detection to the water tank 3-1. The water in the water tank 3-1 enters the box through the circular hole 1-2 to provide the moisture required for the germination of the soybean seeds. Under suitable temperature (such as 25-28°C) and humidity conditions, the soybean seeds start to germinate.

[0049] The camera 3-2 takes pictures of the germination of soybean seeds in the seed germination box 1 every 12 hours. The captured image data is transmitted to the data processing unit 6. The data processing unit 6 performs correlation analysis on the soybean seed germination phenotype data (such as germination rate, bud length, etc.) captured by the camera 3-2 and the spectral data stored previously. Through the accumulation and statistical analysis of a large amount of sample data, a vitality judgment model for soybean seeds is established to judge whether new soybean seeds can germinate and the strength of their germination ability.

[0050] Embodiment 2: Modeling for detecting the vitality of corn seeds

[0051] Select an appropriate amount of corn seeds and sow them on the seed germination box 1 with a 10×10 grid. Gently shake the seed germination box 1 so that the corn seeds accurately fall into the grooves 1-1 in each grid to complete the arrangement of the corn seeds. The seeds not arranged in the grooves 1-1 are allowed to fall naturally by tilting, and carefully check each groove 1-1 to ensure that there is exactly one seed in each;

[0052] Turn on the first conveying mechanism 4 to send the seed germination box 1 containing the arranged corn seeds to the detection position of the near-infrared seed vitality measuring instrument 2. The laser light source 2-1 emits a supercontinuum laser with a wavelength range of 700-2500 nanometers to irradiate the corn seeds. The light signal passing through the seeds is collected by the spectral detector 2-2 through the round hole 1-2 and converted into spectral data for transmission to the data processing unit 6 for storage;

[0053] The conveying mechanism 5 conveys the seed germination box 1 that has completed the vitality detection into the water tank 3-1. The water in the water tank 3-1 penetrates into the box through the round hole 1-2 of the seed germination box 1 to promote the germination of the corn seeds. During the germination period, keep the water temperature in the water tank 3-1 at about 25°C to provide a suitable germination environment;

[0054] The camera 3-2 takes pictures and records the germination of the corn seeds every 12 hours. The captured corn seed germination phenotype data is transmitted to the data processing unit 6. The data processing unit 6 performs corresponding analysis on the corn seed germination phenotype data captured by the camera 3-2 and the spectral data detected by the near-infrared seed vitality measuring instrument 2. Through in-depth research on multiple groups of corn seed sample data, a vitality judgment model suitable for corn seeds is constructed to evaluate the vitality level and germination potential of new corn seeds.

[0055] Only some exemplary embodiments of the present invention are described above by way of illustration. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
