摘要：
Various planting machines and planting methods are described. A planting method may include filling a seed pool with first-type seed, metering the first-type seed from the seed pool with a metering member, and then evacuating the first-type seed from the seed pool. The method may further include filling the seed pool with second-type seed, metering the second-type seed with the metering member, evacuating the second-type seed from the seed pool, and then refilling the seed pool with the first-type seed. First-type and second-type seed may be evacuated to separate temporary storage chambers, and the seed pool may be filled from the temporary storage chambers, as well as from bulk storage containers. A seed valve of a planting machine may include temporary seed storage chambers for different seed types. The seed valve may fill and evacuate a seed pool through rotation of various valve members and selective application of a vacuum.
