A potato seed planting apparatus has: a frame configured to be advanced over a subjacent field into which potato seed is planted; at least one container on the frame for a supply of potato seed; and a plurality of laterally spaced planting units on the frame. Each of the planting units is configured to cause potato seed from the at least one container to be discharged to the subjacent field at controlled time intervals as the potato seed planting apparatus is advanced in a travel path. First and second of the planting units are configured so that the discharge time intervals for potato seeds from the first planting unit are different than the discharge time intervals for potato seeds from the second planting unit with the potato seed planting apparatus advanced at a first speed in the travel path.

In one aspect there is provided a planting unit for singulating a plurality of seeds, said planting unit comprising a seed holder, a seed discharge, at least one drive unit and a seed singulator. The seed singulator further comprises a seed singulating ledge and an excess seed ejector to eject any excess seeds from the seed singulating ledge onto the seed holder.

A planter suitable for block seeds that relates to the technical field of agricultural seeding machinery is disclosed. The planter includes a frame, a fertilizing tank, a fertilizing box, a seeding mechanism, a control mechanism, a seed box, a ridging mechanism, land wheels, a seeding furrower, a fertilizing furrower, a seed-clearing mechanism, and a replanting mechanism. The fertilizing tank, the fertilizing furrower, the fertilizing box, the seeding furrower, the seeding mechanism, the land wheels, the control mechanism, the seed box, and the ridging mechanism are mounted in turn from one end to the other end of the frame. A photoelectric sensor of an active infrared intrusion detector is adopted to dynamically monitor the presence of the seed potatoes on a seed-discharge spoon in a conveying process. Seeds are replanted with the control mechanism when the seeds are sowed with an empty spoon.

The method for planting potatoes at high speed includes the steps of providing a press wheel behind the seed release mechanism; opening a furrow in a soil; dropping potato seed pieces at spaced intervals in the furrow such that each seed piece or a portion thereof intersects a forward shadow of the press wheel, and catching and decelerating each seed piece against the soil in the furrow thereby reducing set roll in each seed piece. In an alternate embodiment a pair of spaced-apart press wheels are used. These alternate press wheels are mounted astride the furrow in a positive-camber alignment for moving the soil of the furrow against the seed piece.
