ができる。Effects of the Invention According to the present invention, a screw is rotatably provided in a fertilization conduit having a feeding port at its lower end for directing fertilizer supplied from a fertilizer hopper toward the feeding port, and this screw is driven by a drive source. By rotationally driving the fertilizer, the fertilizer supplied to the fertilizing conduit can be reliably and continuously delivered toward the outlet without clogging the fertilizing conduit. In addition, since the feeding port is opened at the rear side of the lower end of the fertilizer conduit in the direction of travel, this combined with the forced introduction of fertilizer by the screw prevents the feeding port from becoming clogged with soil and ensures that the fertilizer can reach deep layers from the feeding port. can be fertilized. Furthermore, by storing different types of fertilizers in the fertilizer hopper, these different types of fertilizers can be reliably mixed while being drawn out toward the feeding outlet with a screw in the fertilizing conduit, and then fed out from the feeding outlet to the deep layer. . Therefore, it is possible to provide a deep fertilization device with a simple configuration and excellent workability.
