[0027] The present invention also discloses a seedling-raising method for a smart agriculture seedling-raising system, which specifically includes the following steps: S1. The seedling tray 3 is removed from the seedling raising rack 1: By pulling the rectangular rod 93 outwards, the rectangular rod 93 drives the rectangular plate 94 to move outwards. The rectangular plate 94 will drive the moving plate 52 connected to the L-shaped rod 95 to move towards the front of the seedling raising rack 1. The moving plate 52 drives the toothed plate 55 to move. The toothed plate 55 will drive another toothed plate 55 to move towards the rear of the seedling raising rack 1 through the gear 54. The other toothed plate 55 will drive the rear moving plate 52 to move outwards, so that the seedling trays 3 located in the front and rear move out from the front and rear of the seedling raising rack 1 respectively; S2. Adding seedling soil to the seedling tray 3: Add soil to the seedling tray 3 that has been moved out of the seedling raising rack 1. After the nutrient soil is added, push the rectangular rod 93 inwards to reset it. The rectangular rod 93 will drive the rectangular plate 94 to move back into the mounting frame 2 to reset. The rectangular plate 94 will drive multiple seedling trays 3 to reset into the seedling raising rack 1 through multiple L-shaped rods 95 and multiple moving plates 52, completing the addition of the soil; S3. Digging planting pits in the seedling soil: Rotate the handle to drive the rectangular rod 93 to rotate. The rectangular rod 93 drives the second bevel gear 67 to rotate. The second bevel gear 67 drives the threaded rod 61 to rotate through the first bevel gear 66. The threaded rod 61 drives multiple threaded sleeves 62 to move downwards. The threaded sleeves 62 drive the sliding plate 65 to move downwards through the support plate 63. The sliding plate 65 drives the heat preservation cover 4 to move downwards, so that multiple heat preservation covers 4 move downwards. The multiple conical drip irrigation tubes 71 in the heat preservation cover 4 move downwards. The conical plugging blocks 74 on the conical drip irrigation tubes 71 will insert into the soil, thus forming multiple planting pits on the soil surface; S4. Sprinkling seedling seeds into the planting pits: Then rotate the rectangular rod 93 in the reverse direction to drive the threaded rod 61 to rotate in the reverse direction. The threaded rod 61 will drive multiple heat preservation covers 4 to move upwards and reset through multiple threaded sleeves 62 and the sliding plate 65. Pull the rectangular rod 93 outwards again to move multiple seedling trays 3 out of the seedling raising rack 1. Sprinkle seeds into the planting pits in the seedling trays 3, and bury the soil depressions after the seeds are sprinkled; S5. Insulating the seedling tray 3: Push the rectangular rod 93 inwards again. The rectangular rod 93 drives multiple seedling trays 3 to move into the seedling raising rack 1 to reset. By rotating the rectangular rod 93 again, drive multiple heat preservation covers 4 to move downwards, so that the heat preservation covers 4 are sleeved on the seedling trays 3 for heat preservation; S6. Drip-irrigating nutrient solution: Start the liquid extraction pump 81, and pass the nutrient solution into multiple drain pipes 86 through the nutrient solution delivery pipe 82. Multiple liquid outlet holes 87 on the drain pipes 86 drip-irrigate the nutrient solution downwards. The multiple liquid outlet holes 87 will drip-irrigate the nutrient solution into the conical drip irrigation tubes 71, and the nutrient solution will drip into the seedling trays 3 after passing through the conical drip irrigation tubes 71.

[0028] It should be particularly noted that the downward movement distance of the heat preservation cover 4 in S5 is less than that in S3. When digging planting pits in the soil of the seedling tray 3, the heat preservation cover 4 will move downward and completely cover the seedling tray 3 (as Figure 10 shown). When the heat preservation cover 4 keeps the seedling tray 3 warm, the heat preservation cover 4 only covers one-fifth to one-fifth of the overall height of the seedling tray 3 when moving downward.
