If it is desired to completely clean the inside of a large number of recesses provided in the seedling raising pot, it is desirable to insert a brush into each of the recesses to clean the inside of the recesses. However, the problem with the technique of inserting a brush for each recess is that if the brush is only inserted into the recess by up-down movement, the seedlings are raised while the brush is cleaning the recess. The transport of the pot must be stopped. Otherwise, the brush or the seedling pot may be damaged by the horizontal movement of the seedling pot with respect to the brush that only moves up and down.
However, stopping the seedling pots one by one with the washing apparatus results in a remarkable reduction in work efficiency in performing a continuous washing operation. Therefore, it is desirable to wash the seedlings during the transportation process. Further, if the upper and lower portions of the seedling raising pot are washed in a normal state, there is a problem that the removed dirt accumulates at the bottom of the concave portion.
