It is native to Southeast Asia and is now widely cultivated in tropical and subtropical regions, becoming one of the world's major fruits. Banana trees are usually planting areas formed by multiple banana plants gathered together. The banana trees in the planting area are planted evenly, and the banana trees need to be fertilized after planting.

Through this device, fertilization can be achieved when the banana seedling plant is in contact, avoiding fertilization at the idle position of the banana seedling plant, which greatly reduces the waste of fertilizer during fertilization; Through the relative displacement of the lever 20 and the banana seedling plant, the anti-slip strip 30 can slide along the T-shaped slide groove 29 when contacting the banana seedling plant, and the anti-slip strip 30 drives the clamping strip 39 to move through the T-shaped block 31. The clamping strip 39 intermittently abuts against the toggle protrusion 41 through the clamping teeth on the surface, so that the toggle ring 40 reciprocates under the action of the torsion spring 35. Through this device, the toggle ring 40 drives the nozzle to reciprocate and swing at a certain angle, so that the liquid fertilizer sprayed from the nozzle can be sprayed evenly. At the same time, when the lever 20 leaves the banana seedling plant, the liquid fertilizer inside the water spray pipe 34 can be thrown out through the swing of the nozzle to prevent the liquid fertilizer from drying and blocking the nozzle.
