摘要：In a seedling-interval regulation apparatus, the transport interval between two adjacent seedlings successively transported by a variable speed conveyer is calculated by measuring a distance over which the preceding seedling is transported between a point in time when the preceding seedling is detected by a seedling sensor and a point in time when the succeeding seedling is detected by the seedling sensor. The calculated transport interval between the seedlings is compared with the planting interval. When the calculated transport interval coincides with the planting interval, the transport speed of the variable speed conveyer is maintained. When the calculated transport interval does not coincide with the planting interval, the transport speed of the variable speed conveyer is increased or decreased or the variable speed conveyer is stopped, such that the transport interval between two adjacent seedlings becomes equal to the planting interval immediately after the preceding seedling is discharged from the variable speed conveyer.
