A telescopic rod 56 is fixedly installed on the outer wall of the fertilizer discharge base frame 51 near the transmission rack 55. The driving end of the telescopic rod 56 is fixedly installed with one end of the transmission rack 55. By opening the telescopic rod 56 to extend, the transmission rack 55 drives the transmission gear 54 to rotate, thereby controlling the rotating horizontal shaft 53 to drive the partition plate 52 to rotate. The fertilizer in the partition is discharged through the bottom of the fertilizer discharge base frame 51 and discharged into the space around the seedlings for effective fertilization of the seedlings.

[0027] A second heat sink 57 is fixedly installed on the outer wall of the fertilizer discharge base frame 51 near the telescopic rod 56. The transmission gear 54, transmission rack 55 and telescopic rod 56 are located in the second heat sink 57.

[0028] Working principle: The seedling fertilizer applicator is fixed to the external mobile device using the fixed bracket 1. The external mobile device is used to move the entire seedling fertilizer applicator so as to fertilize a large area of ​​seedlings in the field. Granular fertilizer is introduced into the fertilizer storage frame 2. The granular fertilizer in the fertilizer storage frame 2 is introduced into the metering outer cylinder 31 through the top frame 311 and falls into the storage trough 301 at the top position. By turning on the first motor 363, the worm gear 362 is driven to rotate the worm wheel 361, the auxiliary shaft 36, and the rotating horizontal shaft 34, thereby driving the inner control cylinder 33 to rotate in the outer control cylinder 31, and transporting the fertilizer in the top storage tank 301 to the lower position in sequence. The fertilizer is then discharged into the discharge frame 4 through the installed bottom frame 312. The fertilizer discharged into the discharge frame 4 is then introduced into the fertilizer discharge bottom frame 51 and separated by the partition plate 52. By extending the telescopic rod 56, the transmission rack 55 drives the transmission gear 54 to rotate, thereby controlling the rotating horizontal shaft 53 to drive the partition plate 52 to rotate. The fertilizer in the partition is discharged through the bottom of the fertilizer discharge frame 51 and is discharged into the space around the seedlings to effectively fertilize the seedlings. The control plate 331 slides in the storage tank 301, which flexibly adjusts the storage space in the storage tank 301. This allows for flexible adjustment of the fertilizer discharge amount according to fertilization needs, thereby increasing the overall flexibility of the seedling fertilizer applicator.
