[0002] For crop seeds in agricultural production, in order to increase crop yields and enhance the activity and yield of crop seeds, hybridization is usually used to obtain seeds. Hybrid seeds have certain advantages, such as high germination rate, strong disease resistance, high yield, etc., but at the same time, they also have problems such as difficulty in seed preservation, high requirements for environmental conditions, and high prices.

[0003] In the prior art, the Chinese invention patent with application number 2022100954103 and authorization announcement date of 2023.05.16 discloses a seed treatment device, which is essentially a seed treatment device based on gas-excited negative oxygen ions. Although the invention generates negative oxygen ion gas from a negative oxygen ion generator and enters the seed treatment box, so that the negative oxygen ions are sent into the seed cells, activating the activity of various enzymes such as α-amylase, succinate deoxidase, peroxidase, and superoxide dismutase in the seeds, improving the germination potential and germination rate of the seeds, and ultimately improving the yield and quality of crops such as agriculture, forestry, grass, and vegetables.

[0044] Specifically, a compressor with an automatic drainage function provides compressed air with a pressure of not less than 400 kPa and an air flow consumption of not less than 4 cubic meters per minute, and a first rubber hose 2 with a diameter of 25 mm is used to connect the compressor and a regulating valve 4 with a diameter of 25 mm, respectively, and a second rubber hose 5 with a diameter of 25 mm is used to connect the air source diversion box 6, and both the first rubber hose 2 and the second rubber hose 5 are hoses. The vibration chamber 1 of the seed improvement equipment of the present invention is placed on a horizontal ground with a high flatness through a rubber pad 17, so that the foundation vibration is small. The compressed air enters the air source diverter box 6 through the lower port with a diameter of 19 mm of the air source diverter box 6, then enters the 0.6 mm wide pore 19 through the porous plate 7, and then enters the vibration chamber 1 through the strip through hole 20. The pressure of the air entering the air source diverter box 6 is detected by the pressure gauge 9, and the maximum pressure is 400 kPa. The pressure gauge 9 is connected to the upper port with a diameter of 19 mm of the air source diverter box 6 using a third rubber hose 8 with a diameter of 25 mm.

During the flow of air in the vibration device 29, the regulating valve 4 is adjusted and the pressure value of the pressure gauge 9 is observed to ensure that the pressure value is stabilized at 150 kPa and the gas flow rate is not less than 4 cubic meters per minute. By adjusting the air flow parameter value to this value, the vibration frequency range required for improving the seeds contained in the plastic tube 11 can be met. At the same time, it can ensure the activation of the internal vitality of the seeds, improve the germination potential, germination rate and water absorption of the seeds, and achieve the best effect of seed improvement.

[0045] The amount of seeds that can be improved and processed each time by the present invention is 1.5 grams. The seeds to be improved and processed are placed in a transparent plastic tube 11, and the plastic tube 11 is inserted into a rubber sleeve 12. By observing the center position of the seeds in the plastic tube 11, the position of the plastic tube 11 relative to the rubber sleeve 12 is manually adjusted up and down until the center position of the seeds in the plastic tube 11 is adjusted to be consistent with the center position of the vibration chamber 1. After adjusting to this position, it can be ensured that the seeds to be processed are always in the center position of the vibration chamber 1. The center position of the vibration chamber 1 is the best position to achieve vibration improvement of the seeds; at the same time, under the elastic force of the rubber sleeve 12, the plastic tube 11 can be prevented from falling. In addition, according to the direction of airflow movement in the vibration chamber 1 of the seed improvement device of the present invention, six plates are welded and set around the vibration chamber 1 so that the stretching direction of the six plates is consistent with the direction of airflow movement, thereby ensuring the accuracy and stability of the vibration frequency required for seed improvement.

[0046] Specifically, the opening plate 13 can be reciprocated in the top opening of the vibration chamber 1 through the hand pull ring 16 connected to the end of the opening plate 13, so as to achieve the purpose of controlling the opening degree of the top opening of the vibration chamber 1; the opening plate 13 is placed at different positions in the top opening of the vibration chamber 1, so that different vibration effects of the air in the vibration chamber 1 can be achieved, that is, different vibration frequencies required for improving the seeds contained in the plastic tube 11 can be obtained. After the opening plate 13 is adjusted to the target position, the opening plate 13 can be pressed against the positioning support plate 27 by rotating the handle 15 to tighten the positioning bolt 14 to prevent movement.

[0047] When the top opening of the vibration chamber 1 is adjusted to different openings, that is, when the opening plate 13 is placed at different positions in the top opening of the vibration chamber 1, multiple experimental measurements of the vibration frequency of the seeds contained in the plastic tube 11 are carried out; after comprehensive multiple experimental measurements, it is concluded that for the same seed, the tip of the upper oblique tip of the opening plate 13 is vibrated for 1 minute at a position 50 mm away from the outside of the hole 19, and then the tip of the upper oblique tip of the opening plate 13 is vibrated for another minute at a position 100 mm away from the outside of the hole 19; the vibration frequency under this position adjustment scheme of the opening plate 13 in the top opening of the vibration chamber 1 has the best improvement effect on the seeds contained in the plastic tube 11 after vibration.

[0048] The measurement results of the vibration frequency under the above-mentioned position adjustment scheme of the opening plate 13 in the top opening of the vibration chamber 1 are as follows: the temperature vibration sensor 22 is respectively installed at the center position of the outer surface of the front and rear side walls of the vibration chamber 1 to measure the vibration frequency; (1). The temperature vibration sensor 22 is adsorbed and fixed at the center position of the outer surface of the front side wall of the vibration chamber 1, ensuring that the gas source pressure entering the vibration device 29 is 150 kPa and the gas flow rate is not less than 4 cubic meters per minute. The tip of the upper oblique tip of the opening plate 13 is 50 mm away from the outside of the hole 19, and the vibration is vibrated for 1 minute, and the vibration frequency is measured: 198~271.8 Hz; then the tip of the upper oblique tip of the opening plate 13 is 100 mm away from the outside of the hole 19, and the vibration is vibrated for 1 minute, and the vibration frequency is measured: 190.5~268.6 Hz. (2) The temperature vibration sensor 22 is adsorbed and fixed on the center position of the outer surface of the rear side wall of the vibration chamber 1, ensuring that the gas source pressure entering the vibration device 29 is 150 kPa and the gas flow rate is not less than 4 cubic meters per minute. The tip of the upper oblique tip of the opening plate 13 is 50 mm away from the outside of the hole 19, and the vibration frequency is measured at 169.9 to 267.7 Hz for 1 minute; then the tip of the upper oblique tip of the opening plate 13 is 100 mm away from the outside of the hole 19, and the vibration frequency is measured at 156.3 to 257.6 Hz.

[0049] The following experimental comparison proves that: taking spinach seeds as an example, the number of germination and germination potential of spinach seeds before and after vibration treatment by using the seed improvement device of the present invention are described in detail; (1) 60 spinach seeds are taken and cultured in a culture dish for 4 days under normal conditions. The average number of germinations reaches 9.4 and the germination potential is 15.7%; after culture for 7 days, the average number of germinations reaches 11, the germination potential is 18.3%, and the seed buds are 3.98 cm long;

[0050] (2) 60 spinach seeds were vibrated by the vibration device 29 of the seed improvement equipment of the present invention according to the vibration frequency under the above-mentioned position adjustment scheme of the opening plate 13 in the top opening of the vibration chamber 1. After being cultured in a culture dish for 4 days, the average number of germinations reached 25.6, and the germination potential was 42.7%. On the 7th day of culture, the average number of germinations reached 37.4, the germination potential was 62.3%, and the seed buds were 5.28 cm long.
