摘要：
An opener for depositing fertilizer and seed in a single pass, double-shoot manner includes a rotating disc that cuts a furrow in a planting surface, a fertilizer tube that drops fertilizer into the furrow, and a trailing seed tube assembly, having a cutting edge, that cuts a vertically and horizontally offset trench in the furrow to form a seed bed in the planting surface onto which seed is deposited. The seed trench provides a seed bed that is offset from the bottom of the furrow to provide horizontal and vertical stratification of the seed and fertilizer.
