FIELD: agriculture.SUBSTANCE: planting unit can be used in sowing cultivated and other crops. The planting unit comprises a housing, in which lower part a horizontal sowing disc is mounted. In the sowing disc the conical through holes are made, arranged radially in three rows, directed with the smaller base down. Over the sowing disc an L-shaped partition is mounted, separating the inter-housing space into two zones: a zone of loading and a zone of actuating bodies. In the zone of loading in the upper lid of the housing a loading window charging hole is made. In the zone of actuating bodies a window for seed outlet is made and in it parallel to the L-shaped partition above the horizontal sowing disc a unit of sensors for control of seeds presence is mounted. Under the unit of sensors a unit of pneumatic valves is mounted, which are controlled by an electronic control device. The outlet nozzles of the pneumatic valves are mounted coaxially to the conical openings of the sowing disc.EFFECT: invention enables to increase the efficiency of precision planting seeds with simultaneous application of mineral fertilizers and to extend the functional capabilities.2 cl, 4 dwg |
