摘要：
A flexible seed metering disk, comprising a first disk layer, and a second disk layer, wherein the first disk layer has a first pattern of holes which pass completely through the first disk layer, wherein the second disk layer has a second pattern of holes which pass completely through the second disk layer, and wherein the first disk layer is placed in contact with the second disk layer such that at least a subset of holes from the first pattern of holes lines up with at least a subset of holes from the second pattern of holes, creating openings in the flexible seed metering disk which pass through both the first disk layer and the second disk layer, whereby various configurations of the flexible seed metering disk can be created by rotating the first disk layer in relation to the second disk layer to create alternative alignments.
