This technology involves knowledge from multiple fields such as seed science, plant physiology, and agricultural biotechnology. It aims to create suitable conditions to promote the initiation and acceleration of physiological and biochemical processes inside seeds, thereby achieving rapid and uniform germination, including the following aspects:

[0003] 1. Seed selection and treatment: First, select healthy and vigorous seeds as the objects for germination. Seed treatment may include disinfection, soaking, shelling and other steps to remove inhibitory substances on the seed surface, soften the seed coat, and increase the water absorption capacity of the seeds;

[0004] 2. Water management: Water is one of the key factors for seed germination. By controlling the soaking time and water temperature, the rate and degree of water absorption of seeds can be adjusted to provide sufficient water for the metabolic activities inside the seeds;

[0005] 3. Temperature control: Appropriate temperature can promote the activity of enzymes inside seeds and accelerate the transformation and transportation of nutrients. During the germination process, constant temperature boxes or geothermal lines are usually used to provide a stable temperature environment for seeds;

[0006] 4. Oxygen supply: Seed germination requires a lot of energy, which depends on the respiration inside the seeds. Therefore, ensuring sufficient oxygen around the seeds is crucial to maintaining normal respiratory metabolism;

[0007] The prior art maintains humidity by spraying seeds, but due to the need to ensure air circulation, water loss is too fast, so frequent spraying is required. The utility model solves the above problem. Utility Model Content

[0024] After the rice seeds are covered with the seedling tray 3, they are pushed into the germination box 1 along the seedling tray chute 2. The end of the seedling tray 3 contacts the inwardly inclined pressing plate 4 and presses the pressing plate 4. The pressing plate 4 drives the pressing plate 6 and the absorbent pad 9 to rotate with the fixed shaft 5 as the axis. When the pressing plate 4 becomes vertical, the pressing plate 6 and the absorbent pad 9 horizontally cover the rice seeds. The seedling tray 3 seals and locks the seedling tray in the germination box 1. The germination box 1 is filled with water and soaked for 8-10 hours and then drained. Under the covering effect of the absorbent pad 9, the seeds will not be washed away. After drainage, the moisture in the absorbent pad 9 is retained, and the excess moisture flows down through the end of the seedling tray 3. The absorbent pad 9 maintains the temperature and humidity required for seed germination. The air circulation system keeps the germination box 1 with sufficient oxygen. The air enters through the pores of the gauze of the absorbent pad 9 to ensure the oxygen required for germination.

[0025] A threaded hole 10 is provided on the side wall of the germination box 1, and a fixing plate 11 is connected to the outside of the seedling tray 3, and the fixing plate 11 is connected to the threaded hole 10 through a stud;

The water enters the branch pipe 13 through the injection pipe 12, and then is discharged obliquely downward through the liquid outlet hole 14 to directly hit the pressure plate 6. The water passes through the long hole 15 of the pressure plate 6 and is absorbed by the water absorbent pad 9. The water in the water absorbent pad is evenly soaked and diffused. Water that exceeds the water absorption limit will flow down along the end of the seedling tray and will not soak the seeds.
