4. A method for using an oat seedling cultivation device, applied to the oat seedling cultivation device according to claim 3, characterized in that: include: Step 1: Pull the clamping plate (54) to make the extension plate (59) clamped to the lower end of the fixed rail (3), and use the spring piece (56) to drive the rotating drum (53) to rotate, so that the clamping plate (54) is clamped on the fixed rail (3). At this time, the roller (58) will be clamped to the inner side of the slide groove (8), and the roller (58) and the first rolling ball (510) can facilitate the movement of the U-shaped frame (51) on the fixed rail (3), so as to facilitate the movement of the seedling pot (4); Step 2: Move the two groups of seedling raising pots (4) closer to each other, so that the second connecting tube (611) at the front end of the rear group of seedling raising pots (4) is tightly attached to the first connecting tube (61) of the front group, insert the insert ring (619) into the inner side of the slot (618), and then screw the internal thread tube (612) so that the internal thread tube (612) is screwed onto the external thread tube (63), so that the front and rear groups of seedling raising pots (4) are connected to each other; Step 3: When the second connecting tube (611) at the rear end is connected to the first connecting tube (61) at the front end, the push rod (615) on the inner side of the second connecting tube (611) of the rear group will be inserted into the inner side of the first connecting tube (61) of the front group, and the blocking piece (69) will be pushed out from the inner side of the first connecting tube (61), so that the first spring (610) will shrink. At this time, the blocking rod (66) will move forward, so that the second rolling ball (68) is pressed against the surface of the blocking block (73) on the inner side of the seedling pot (4) and squeezes the blocking block (73) away from the rear end of the second connecting tube (611) at the front end of the first connecting tube (61), so that the plug (67) is inserted into the inner side of the ring (617) on the inner side of the second connecting tube (611) at its front end; Step 4: When the internally threaded tube (612) is unscrewed from the externally threaded tube (63), the first spring (610) will rebound, causing the blocking piece (69) to block the first connecting tube (61) again, while driving the plug (67) to move out from the inner side of the ring (617). At this time, the second spring (74) will push the sliding shaft (72) out from the inner side of the fixed block (71), causing the blocking block (73) to block the rear end of the second connecting tube (611) again.
