The fleshy roots of turnips are thick and spherical or conical in shape, and the epidermis is mostly white or yellowish-green. They have a crispy texture and a slightly spicy taste. They are common vegetables and pickling ingredients. When growing turnips, seedlings are usually raised first and then transplanted. When the turnip seedlings grow to 3 - 4 true leaves and the seedling age is about 20 - 25 days, they can be transplanted, thereby improving the cultivation quality and efficiency of turnips.

10. Method for intensive seedling cultivation device of turnip in plug trays, characterized in that: Including the turnip plug tray intensive seedling cultivation device according to any one of claims 1-9, the steps are as follows: S1: Material preparation. First, the seedbed (36) is successively laid flat on the inner bottom of the seedling tray (2), then the limiting frame (37) is snap-connected to the inner side wall of the seedling tray (2), then the seedling cups (3) are successively inserted into the middle of the positioning grooves (38), and then the prepared seedling tray (2) is snap-connected to the inside of the third notch (29). S2: Add the substrate. Pour the substrate into the interior of the first electric push rod (5), and then start the first motor (17) to drive the first stirring rod (31) to rotate, thereby accelerating the crushing of the substrate. Then open the valve in the middle of the feeding pipe (30) so that the crushed substrate falls into the interior of the first pneumatic conveying pump (7) under the action of gravity. Start the first pneumatic conveying pump (7), and under the action of wind force, use the substrate to be injected into the middle of the seedling cup (3) via the second connecting pipe (16) and the first discharge pipe (12) and then from the first discharge port (20). Start the first electric push rod (5) to drive the movable support (8) to move horizontally, thereby changing the position of the first discharge port (20) to fill the substrate. Start the third electric push rod (25) to drive the scraper (26) to move vertically to change the height of the scraper (26) to level the substrate. Then start the second electric push rod (19) to drive the mounting plate (9) to move vertically downward, so that the inserting rods (24) are sequentially inserted into the middle of the seedling cups (3) filled with the substrate for hole pressing; S3: Sowing. Place the turnip seeds in the interior of the disinfection tank (10) for soaking. Start the second motor (18) to drive the second stirring rod (35) to rotate to accelerate the fluidity during seed soaking. After soaking is completed, open the valve at the end of the filter (33) to drain the disinfectant solution. Then open the valve at the bottom of the three-way pipe (32) so that the seeds fall into the interior of the second pneumatic conveying pump (11) under the action of gravity. Then start the second pneumatic conveying pump (11) to convey the seeds into the interior of the second discharge pipe (14) by air force. When the inserting rod (24) moves to directly above the hole-pressed position, start the third motor (2101) to drive (2104) to rotate, so that the seeds clamped in the groove (2103) fall into the hole-pressed interior via the inserting rod (24) under the action of gravity. Then adjust the mounting plate (9) to change the position of the first discharge port (20) to output the substrate to cover the seeds. The planting personnel take out the seedling tray (2) and place it on the surface of the support frame (1), thereby completing sowing.
