Abstract

The invention relates to agriculture and can be used when sowing agricultural crops under conditions of insufficient moisture. The purpose of the invention is to increase the yield by creating favorable conditions for seed germination and plant growth in areas of insufficient moisture. Sowing is made in the furrows 3 ... 4 cm deeper than the dry soil layer. The vertical walls of the furrows are cut by paired disks 1 with flanges 2. Between the disks, there is a knife 3 with a blade 4, which cuts a layer of soil in a horizontal plane and with the help of a blade brings the soil to the floor surface. The working edge of the knife is beveled at an angle of 45 ° to the longitudinal axis, and the working surface of the knife is made ribbed to cut the longitudinal grooves of a triangular cross section with a depth of 7 ... 10 cm at the bottom of the furrow. The seeds are sown in the grooves of the seed guide 5, mounted behind the knife, and rolled by the roller 6 following the seed guide 6. The seed cover with moist soil is produced by the locker 8 mounted behind the roller. The overhang is made in the form of paired knives with different-sized wings fixed on a vertical cylindrical hinge 7 at an acute angle to each other. The cutting edges of the zagortach knives are made along cylindrical formers. At the longitudinal end of the small wing, a replicating ski 9 is rigidly mounted, set at 2 ... 3 cm below the wings in front of the larger blade. Zagortach, copying the bottom of the furrow with seeds with a ski, cuts the soil with the knives from the furrow walls 2 ... 3 cm above the seed and covers the seeds with a layer of moist soil 2 ... 3 cm, leaving the furrows not filled up to the full depth. A favorable microclimate is created in the furrows, a more complete retention of the flow of storm water occurs, which contributes to the good development of crops in drought conditions. 2 sec. and 6 z. p. f-ly, 4 ill., 1 tab.
