[0029] With the addition of the topdressing component 8, one end of the topdressing cylinder 9 can be inserted into loose soil during operation. Pressing the handle 16 causes the support component 15 to rotate. As the support component 15 rotates, one end of the sliding rod 13 is pressed down, and the handle 16 is compressed. Simultaneously, as the sliding rod 13 descends, the support rod 14 descends and opens, thus opening the conical nozzle 18. At this point, the fertilizer is poured into the soil. After the conical nozzle 18 opens and the fertilizer falls, the topdressing cylinder 9 can be pulled out to complete the overall topdressing process. This effectively improves the overall efficiency of topdressing and minimizes the need to carry additional tools, ensuring the smooth progress of subsequent topdressing work.

[0030] The top dressing cylinder 9 has symmetrically protruding threaded rods 10 on its side near the top. The threaded rods 10 are threadedly engaged with the handle 11. The detachable handle 11 allows for quick and easy replacement if it is damaged.

[0031] Working principle:

[0032] During operation, fertilizer is poured into the container 1 through the inlet 2. The fertilizer then enters the topdressing cylinder 9 through the connecting pipe 7. The conical nozzle 18 is inserted into the loose soil where fertilizer needs to be applied. The handle 16 is pressed, causing the support assembly 15 to rotate. As the support assembly 15 rotates, one end of the sliding rod 13 is pressed down, and the sliding rod 13 compresses the handle 16. Simultaneously, as the sliding rod 13 descends, the support rod 14 descends and opens, thus opening the conical nozzle 18. At this point, some fertilizer is poured into the soil. After the conical nozzle 18 opens and the fertilizer falls, the handle 16 is released. The compressed handle 16 pushes the sliding rod 13 upward, causing the conical nozzle 18 to close while the handle 16 descends.

[0033] All technical features in this embodiment can be freely combined according to actual needs.
