The use of spherical notched and needle-shaped rotary discs for soil cultivation in the aisles of garden plantings

   Relevance. Soil cultivation in the aisles of perennial plantations has its own characteristics. In this connection, there is a constant improvement of units for tillage.
   Methods. The present research in the direction of no-till maintenance of row spacings was carried out in the conditions of fruit-bearing apple orchards of the varieties Renet Simirenko, Idared, located in AO “KSP “Svetlogorskoe””, Krasnodar region. Modification of the existing units for tillage was carried out on our own in the conditions of the farm's workshops. Long-term studies of the quality of work of the units and the advantages obtained through their operation have been carried out.
   Results. А constructive scheme of a double-row discator with cut-out discs in conjunction with needle rotary discs for surface tillage in the aisles of apple orchards was proposed, which makes it possible to improve the qualitative performance of the discator, reduce specific, energy and labor costs, change the intensity of seam turnover, and create a multifunctional tillage unit in the future, capable of carrying out not only surface tillage, but also (after replacing the working organs) to cut rows, ridges, and apply physiologically active substances. Optimized modes of operation of the modernized double-row discator BDM 2.5 x 2 in the spacing of garden plantings have been developed: at the working speed of the discator BDM 2.5 x 2 7–8 km/h, the productivity was 2–2.3 ha/h, the tillage depth was 7–15 cm, the soil was crumbled into fractions up to 50 mm in size, weeds were cut to 98 %, the ridging of the soil was 5–17 cm, the fuelconsumption was 6–6.5 kg/ha, the traction resistance did not exceed 980 kg.
