FIELD: forest industry, in particular, sowing of large-fruit seeds of forest crops, such as oak acorns. ^ SUBSTANCE: apparatus has frame, shank, seeding unit, covering roller, and slide-type supports. Three disk knives are disposed in parallel with one another in front part of frame and subsoiler-skim is positioned immediately rearward of subsoiler-skim. Wavy disk is positioned rearward of skim for rotation on immovable shaft fixed on frame. Diameters of disk knives are determined from formula: D1=(2.5-2.6)H. Diameter D2 of wavy disk is determined from ratio D2=(1.05-1.1)D1, where D1 are diameters of disk knives, D2 is diameter of wavy disk, H is seed furrow depth. ^ EFFECT: increased efficiency by providing simultaneous presowing treatment of soil and sowing of large-fruit forest crop seeds. ^ 1 dwg |
