摘要
A method and device for improving mechanical transplanting of balled seedlings involves detection of balls with deficient seedlings, such as those with no seedlings or undersized seedlings, with a sensor through an aperture in a compartment holding the ball. Deficient balls are allowed to exit from the compartment through a shutter, and replacement balls are provided from a seedling supply. The replacement seedling supply includes a cassette having one row of cells for seedlings and the cassette is advanced, as necessary, by a geared shaft engaging the side of the cassette. Alternatively, replacement seedlings are provided from a cultivating tray.
