FIELD: agricultural engineering, in particular, equipment for sowing of cucurbitaceous seeds to different depths for producing stable sprouts to be cultivated under continental climate conditions. ^ SUBSTANCE: drill section has casing with seed box, strip-type seeding unit, shank connected through connecting rod to casing, coverer, covering wheel, and sweep. Section is connected to drill frame through four-link leverage system. Shank comprises cheeks with three tips therebetween. Left-handed and right-handed tips are beveled toward central tip and are positioned between cheeks at different height, correspondingly, two and four centimeters higher than lower cut of central tip. Embedding of seeds at different depths of from 4 cm to 10 cm allows favorable seed germination conditions to be created for at least one seed. ^ EFFECT: increased efficiency in producing of stable germinated seeds under disadvantageous climatic conditions. ^ 7 dwg |
