The utility model relates to agricultural engineering and provides simultaneously with a band sowing of crops two-level application of mineral fertilizers: the starting dose is in the longline with the seeds and the main dose is 3 ... 5 cm below the seed level between the planted strips.Combined disk working body for sowing crops includes a housing 1 with parallelogram suspension 2 and 3, a knife 4, openers 6 and 7 with a seven-way valve and a lock and a depth stop 8.The knife is made in the form of a wedge-shaped coulter 4 with a stand with a tuft guide 5 along its rear wall, has the ability to adjust in height. Left and right single disc anchor (ODA) coulters 6 and 7 band seeding with the same angle of attack of the disks are placed on the sides of the housing 1 in accordance with the row spacing, and in the longitudinal direction with an offset of 25… 35 cm ... 5 cm below the base of the ODA coulters 6 and 7. A depth stop 8 is attached opposite the front ODA coulter 6 on the other side of housing 1.The knife-opener 4 is equipped with a stem stalk 9, made in the form of a smooth flexible elastic rod. The stalk retainer 9 is attached with a lower end flush to the surface of the knife 4 near its leading edge at a level of 8 ... 10 cm from its base. First, the stem stalk 9 moves away from the knife 4 up and back at an angle to the horizontal, close to the crumbling angle (α), then moves sideways along a conjugate arc with an exit to the level of 15 ... 17 cm from the base of the knife 4.The introduction of the device will allow to increase the yield, depending on the specific conditions, up to 50% in comparison with single-level application of fertilizers in one tier with seeds and reduce the energy intensity of the process. 1 sec. f-ly, 2 ill.Полезная модель относится к сельскохозяйственному машиностроению и обеспечивает одновременно с полосным посевом культур двухуровневое внесение минеральных удобрений: стартовой дозы - в ярус вместе с семенами и основной дозы - н
