PROBLEM TO BE SOLVED: To provide a method for supplying soil for raising seedling pots solving the problem of an increase in cost for supplying soil as a result of setting a soil feeding-out device having a hopper and a belt on a transfer board.SOLUTION: A method for supplying soil for raising seedling pots comprises: disposing a soil supply device 5 composed of a bucket conveyor 6 which lifts and conveys soil with a plurality of buckets 7 to the lateral position at a predetermined place of a transfer board 1 transferring a plurality of raising seedling pots P disposed on a tray T dropping the soil lifted and conveyed by the bucket conveyor 6 on the raising seedling pots P in the course of transfer on the transfer board 1 making the raising seedling pots P in the course of transfer receive the soil dropped from the bucket conveyor 6 once accumulating a prescribed amount of soil equal to or more than a necessary amount to be charged in each of the raising seedling pots P on each of the raising seedling pots P in layers and charging a necessary amount of the soil received by the raising seedling pot P into each of the raising seedling pots P when removing extra soil from the raising seedling pot P.COPYRIGHT: (C)2013,JPO&INPIT【課題】ホッパとベルトを有する土繰出装置を移送台上に設置するので、その分、土供給コストが上昇する。【解決手段】トレイTに載置した複数の育苗ポットPを移送する移送台1の所定位置の側方位置に、複数のバケット7により土を揚送するバケットコンベア6により構成した土供給装置5を配置させ、前記バケットコンベア6が揚送させた土を、移送台1上を移送中の育苗ポットPに上に落下させ、移送中の育苗ポットPにバケットコンベア6から落下する土を受け止めさせ、育苗ポットP上に、各育苗ポットPに充填する必要量以上の所定量の土を層状に一旦貯留させ、育苗ポットP上の余分な土を除去する際に、育苗ポットPが受け止めた土のうち必要量の土を各育苗ポットP内に充填させて行う育苗ポット用土供給方法。【選択図】図8
