FIELD: agriculture.
SUBSTANCE: system contains a source of excess air pressure series-connected with pneumatic pipelines, as well as a centralised hopper with a dispenser including a unit separate coils on the shaft, and a distributor of seeds. The distributor is connected to the dispenser through the valve. The separate coils in the unit are divided by sealed bulkheads forming sections, the number of which corresponds to the number of pneumatic pipelines, with which they are respectively connected. In the sections the valve is designed as a screw. The screws of all the sections are located on the same shaft.
EFFECT: invention enables to improve the accuracy of making a given seeding rate and uniformity of their distribution on the surface of the field.
