In the figure, reference numeral 45 is a spare seedling placing table, which is provided on the rear side of the control seat 5 by a rotary link 46 and a rotary expandable link 47 which is rotatable and can expand and contract on the side of the towing vehicle body 1. ing. The fertilizer tanks 34 of the fertilizer application device 33 are arranged in a space below the spare seedling placement table 45.

In the configuration of the above example, after the seedlings are placed on the seedling tank 9 and the fertilizer tanks 34 of the fertilizer application device are filled with fertilizer, the rice transplanting device 7 is moved downward and the leveled float 11 ...
Is grounded on the soil surface, the rice planting device 7 is towed by the tow vehicle body 1, and each rotating portion is transmission-rotated. Then, the seedling planting device 10 ... splits the seedlings for each stock from the seedling tank 9 that laterally reciprocates laterally, and plants the seedlings on the soil surface that is leveled by the lateral protrusions of the leveling float 11. .. Simultaneously with the seedling planting operation, the feeding device 35 of the fertilizer application device 33 is operated, and the fertilizer tank 34 is moved in the groove of the rotary roll 35a.
A predetermined amount of the fertilizer therein is fed out, flows down through the hose 36, and is discharged into the groove formed by the grooving device 37a to be fertilized.

In this way, fertilization work is performed at the same time as the seedling planting work, but when the seedling planting work nears the end in one field, it becomes a multi-row planter planting machine, so all seedling planting equipment If the seedlings are planted to the end with 10 ..., a wide residual planting width may occur between the ridge and the final row of planting seedlings. In such a case, before the final seedling planting step, the seedling planting device located on the unplanted side of the rice transplanter, for example, the clutch 19 of the seedling planting device on the left side in FIG. And cut through the two seedlings on the left side. At this time, the feeding device 35 of the left fertilizer application device 33
The shutter 38 of the part is operated by the wire 43a so as to cover the upper surface of the rotary roll 35a, and at the same time, the fertilization between the left two rows of seedling planting lines is stopped.

Then, in the final seedling planting step, the operation of the left seedling planting device is restarted to carry out seedling planting work so as to prevent unplanted plants. Therefore, during the seedling planting work, when the appropriate number of seedling planting works of the multi-row planting machine are stopped for the purpose of reducing the unplanted width in the ridge of the field, fertilization of the stopped seedling planting line is performed. It can be stopped at the same time and fertilization is applied to the part where seedling planting is stopped, and when planting seedlings in this part again, there is no inconvenience that fertilization is applied again, and growth inhibition due to excessive fertilization And growth spots do not occur.

In particular, since the fertilizer tank 34 and the feeding device 35 for feeding fertilizer from the fertilizer tank are mounted in front of the main power transmission case portion 8a located at the rear portion of the fuselage, the relative movement of the fuselage is relatively high. The front-rear balance is good and the running performance is good, so proper seedling planting and fertilizing work can be performed. Further, since the grooving device 37a is provided on the rear side of the main body with respect to the front end of the main transmission case portion 8a, the fertilizer application position is on the side of the seedling planting position in the side view of the main body. Even if the fertilizer is moved, the fertilization position can be maintained at an appropriate position for the planted seedlings, and growth failure due to excessive or insufficient fertilization is not caused.

Further, by disposing the guide body A for guiding the fertilizer through the space B between the main transmission case portion 8a and the seedling tank 9, the fertilizer transfer path can be shortened, causing troubles such as clogging of the fertilizer. Rarely. In the example of the embodiment, the fertilizer application device is provided for each two-row seedling planting unit, but it goes without saying that the fertilizer application device may be provided for each one-row operation.
