[0045] The present invention also discloses a seedling raising method of a smart agricultural seedling raising system, which specifically comprises the following steps:

[0046] S1, the seedling tray 3 is moved out of the seedling rack 1: by pulling the rectangular rod 93 outward, the rectangular rod 93 drives the rectangular plate 94 to move outward, and the rectangular plate 94 drives the movable plate 52 connected to the L-shaped rod 95 to move toward the front of the seedling rack 1, and the movable plate 52 drives the toothed plate 55 to move, and the toothed plate 55 drives the other toothed plate 55 to move toward the rear of the seedling rack 1 through the gear 54, and the other toothed plate 55 drives the rear movable plate 52 to move outward, so that the seedling trays 3 located at the front and rear are moved out from the front and rear of the seedling rack 1 respectively;

[0047] S2, adding seedling soil to the seedling tray 3: add soil to the seedling tray 3 moved out from the seedling rack 1. After the nutrient soil is added, push the rectangular rod 93 inward to reset. The rectangular rod 93 will drive the rectangular plate 94 to move to the mounting frame 2 and reset. The rectangular plate 94 will drive multiple seedling trays 3 to reset to the seedling rack 1 through multiple L-shaped rods 95 and multiple movable plates 52, completing the addition of soil;

[0048] S3. Digging planting holes in the seedling soil: Turning the handle drives 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 the multiple threaded sleeves 62 to move downward, the threaded sleeves 62 drive the sliding plate 65 to move downward through the support plate 63, the sliding plate 65 drives the heat preservation cover 4 to move downward, so that the multiple heat preservation covers 4 move downward, the multiple conical drip irrigation tubes 71 in the heat preservation cover 4 move downward, and the conical blocking blocks 74 on the conical drip irrigation tubes 71 will be inserted into the soil, thereby forming multiple planting holes on the soil surface;

[0049] S4. Sowing seeds for seedlings in the planting pits: Rotate the rectangular rod 93 in the opposite direction to drive the threaded rod 61 to rotate in the opposite direction. The threaded rod 61 will drive the multiple heat-insulating covers 4 to move upward and reset through the multiple threaded sleeves 62 and the sliding plate 65. Pull the rectangular rod 93 outward again to move the multiple seedling trays 3 out of the seedling rack 1, and sow seeds in the planting pits in the seedling trays 3.

The multiple liquid outlet holes 87 will drip the nutrient solution into the conical drip irrigation tube 71, and the nutrient solution will drip into the seedling tray 3 through the conical drip irrigation tube 71.

[0052] It should be noted that the distance that the heat preservation cover 4 moves downward in S5 is less than the distance that the heat preservation cover 4 moves downward in S3. When the soil of the seedling tray 3 is dug to plant the pit, the heat preservation cover 4 moves downward and is completely covered on the seedling tray 3 (such as Figure 10 As shown), when the heat-insulating cover 4 is keeping the seedling tray 3 warm, the heat-insulating cover 4 only covers one-fifth to one-fifth of the overall height of the seedling tray 3 downward.

The seedling tray (3) is moved out of the seedling rack (1): by pulling the rectangular rod (93) outward, the rectangular rod (93) drives the rectangular plate (94) to move outward, and the rectangular plate (94) drives the movable plate (52) connected to the L-shaped rod (95) to move toward the front of the seedling rack (1), and the movable plate (52) drives the toothed plate (55) to move, and the toothed plate (55) drives the other toothed plate (55) to move toward the rear of the seedling rack (1) through the gear (54), and the other toothed plate (55) drives the rear movable plate (52) to move outward, so that the seedling trays (3) located at the front and rear are moved out from the front and rear of the seedling rack (1) respectively; S2. Adding soil to the seedling tray (3): adding soil to the seedling tray (3) moved from the seedling rack (1). After the nutrient soil is added, the rectangular rod (93) is pushed inward to reset. The rectangular rod (93) drives the rectangular plate (94) to move to the mounting rack (2) and reset. The rectangular plate (94) drives the plurality of seedling trays (3) to reset to the seedling rack (1) through the plurality of L-shaped rods (95) and the plurality of movable plates (52), thereby completing the addition of soil. S3. Digging a planting pit for the seedling soil: rotating 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 the plurality of threaded sleeves (62) to move downward, the threaded sleeves (62) drive the sliding plate (65) to move downward through the support plate (63), the sliding plate (65) drives the heat preservation cover (4) to move downward, so that the plurality of heat preservation covers (4) move downward, the plurality of conical drip irrigation tubes (71) in the heat preservation cover (4) move downward, and the conical blocking blocks (74) on the conical drip irrigation tubes (71) are inserted into the soil, thereby forming a plurality of planting pits on the soil surface; S4, spreading the seedlings in the planting pit: the rectangular rod (93) is rotated in the opposite direction to drive the threaded rod (61) to rotate in the opposite direction, and the threaded rod (61) drives the multiple heat-insulating covers (4) to move upward and reset through the multiple threaded sleeves (62) and the sliding plate (65), and the rectangular rod (93) is pulled outward again to move the multiple seedling trays (3) out of the seedling rack (1), and the seeds are spread on the planting pits in the seedling trays (3), and the soil pits are buried after the seeds are spread; S5, heat-insulating the seedling tray (3): pushing the rectangular rod (93) inward again, the rectangular rod (93) drives the plurality of seedling trays (3) to move to the seedling rack (1) and reset, and by rotating the rectangular rod (93) again, drives the plurality of heat-insulating covers (4) to move downward, so that the heat-insulating covers (4) are placed on the seedling tray (3) for heat-insulating; S6, drip irrigation of nutrient solution: start the liquid pump (81), pass the nutrient solution into the multiple drainage pipes (86) through the nutrient solution delivery pipe (82), and the multiple outlet holes (87) on the drainage pipes (86) drip the nutrient solution downward. The multiple outlet holes (87) will drip the nutrient solution into the conical drip irrigation tube (71), and the nutrient solution will drip into the seedling tray (3) through the conical drip irrigation tube (71).
