METHOD AND SEEDER UNIT FOR GROWING TILLED CROPS Russian patent published in 1997 - IPC

FIELD: agriculture and agricultural engineering. SUBSTANCE: method involves tilling soil; wide-row sowing of seeds in alternating rows of maternal and paternal plants; harvesting; embedding seeds of paternal plants into soil at depth smoothly variable along row length in sine-shaped curve at 3-6 cm interval, with ratio of maternal and paternal plant rows being 3:1. When seeder unit advances along the field, rows of paternal plants are positioned at one edge. Crop is harvested by seeder units with required width. Seeder unit has at least eight seeding sections including skid-type shank and compaction roll. Compaction rolls in two seeder sections are mounted on shaft with eccentricity. EFFECT: increased efficiency, simplified construction and enhanced reliability in operation. 8 cl, 9 dwg
