31 ′, 33, 33 ′, shallow layer nozzles 32, 32 ′, 35, 35 ′, and the nozzles 31, 31 ′, 33, 33 ′, as the fertilizer application machine 1 runs.
Dots are poured into the fields at 32, 32 ', 35, 35'.

Then, as shown in FIGS. 9 to 11, the fertilizer application section 5
Fertilizer 107 is poured into the deep and shallow layers at the
6 is sown in the middle of the deep and shallow layers, so in the early stages of seedling growth, the seedlings absorb shallow and close shallow layer fertilizers, and when the seedlings grow further, they absorb deep and distant deep layer fertilizers. Then, the fertilizer can be absorbed according to the growth of the seedling, and the growth of the seedling can be promoted.

Next, a partially modified embodiment will be described with reference to FIG.

In the embodiment shown in FIG. 12, the second pump shown in FIG.
111 is omitted, and only the first pump 110 is provided. Four screw pumps out of six stations of the pump 110 are connected to the first distribution valve 19, and two screw pumps are connected to the second distribution valve 20. It is connected to the. As a result, the first distribution valve 19 has the first
A large amount of fertilizer is supplied through the tube group 153 of the above, the deep nozzle is applied a large amount of fertilizer, and a small amount of fertilizer is supplied to the second distribution valve 20 through the second tube group 155. Thus, the shallow nozzle is configured to apply fertilizer at a low rate. Therefore, in the early stage of seedling growth, the roots of the seedlings absorb a small amount of fertilizer from the shallow nozzle, and when the seedlings grow further, the roots of the seedlings absorb a large amount of fertilizer from the deep nozzle. The seedlings can absorb the required fertilizer according to their growth, and the seedlings can be satisfactorily grown.

In the above embodiment, the seeding device 50 is used as the ground working unit 6.
However, the present invention is not limited to this, and it goes without saying that a transplanting device for transplanting seedlings such as a rice transplanting device may be used.
