SOWING METHOD AND APPARATUS Russian patent published in 1999 - IPC

FIELD: agricultural engineering, in particular, sowing of crops, such as soya, buckwheat, millet, kidney beans, and alfalfa to produce seeds. SUBSTANCE: method involves providing additional seed flows at an angle to both sides of main seed flow in equally spaced relation to it. Seeds are thrown in furrow at different distances relative to axis of outer single-grain row. Apparatus has vertical seeding disk, rings with cells, with cells in outer rings being positioned at an angle to disk axis, and seed ejectors arranged in outer cell rows at an angle to axes of cells of central row in seeding disk. Such method and construction of apparatus allow protective zones of reduced size to be used during interrow cultivation operations. EFFECT: improved uniformity in distributing seeds over furrow bottom and enhanced reliability in operation. 3 cl, 3 dwg
