PROBLEM TO BE SOLVED: To improve operability and planting accuracy.SOLUTION: In a seedling transplanter, a traveling device, a seedling transfer part for transferring seedlings, and a seedling planter (6) for planting the seedlings transferred to a planting supply position A by the seedling transfer part into a farm field are arranged, the seedling planter (6) plants the seedlings into the farm field by operating a seedling planting gripper for gripping the seedlings in the planting supply position A at the rear side of the seedling transfer part in a prescribed trace, a liquid agent discharge port for discharging a liquid agent to the farm field is formed at the seedling planting gripper or in the vicinity of the seedling planting gripper, a liquid agent tank 124 for storing the liquid agent is arranged in a position at the front side rather than the seedling transfer part and at the outside in left and right directions, and a supply pipe 128 for sending the liquid agent to a liquid agent discharge port from the liquid agent tank 124 is made to pass a one side in the left and right of the seedling transfer part, and arranged.【課題】 本発明は、作業性や植付精度を向上させることを課題とする。【解決手段】 走行装置と、苗を搬送する苗搬送部と、苗搬送部によって植付供給位置Ａへ搬送された苗を圃場に植付ける苗植付け装置６とを設け、苗植付け装置６は、苗搬送部の後側で植付供給位置Ａの苗を挟持する苗植付け挟持具を所定の軌跡で作動させて苗を圃場に植付ける構成とし、苗植付け挟持具又は苗植付け挟持具の近くに圃場に液剤を吐出する液剤吐出口を設け、苗搬送部よりも前側で且つ左右方向外側の位置に液剤を貯留する液剤タンク１２４を設け、液剤タンク１２４から液剤吐出口へ液剤を送る供給管１２８を、苗搬送部の左右一側方を通過させて設けた苗移植機とする。【選択図】図３
