Analysis of agrotechnical indices of working organs for layered soil-free tillage

Abstract

In the layer-by-layer treatment of the soil, a moisture accumulating layer is formed inside the formation. To form a moisture accumulation layer, it is necessary to optimize the design of the ripper for shallow working of the layered working organ. The aim of the study is a comparative evaluation of the agrotechnical indices of the technological process of layer-by-layer soil-free tillage. The design of the working organs under investigation contains a rack with a chisel for deep tillage. In the front part of the rack there are removable plowshares. On the bit is fixed with the possibility of moving the crusher and the thrust plate is located. At the top of the rack is mounted with the ability to replace the ripper for shallow tillage. Experimental data on agrotechnical indices of the technological process of layer-by-level tillage of new working bodies with elliptical, planar (metal and plastic) ripper were obtained on the experimental field. Ultra-high-molecular-weight low-density polyethylene was installed on the ripper, chisel, crumbler and thrust plate of the working device for layer-by-layer soil-free tillage with plastic elements. The working bodies correspond to the agrotechnical requirements. The deviation of the depth of treatment from the preset 2,83-6,88 %, the combability was 0-7,53 cm, fractions up to 50 mm in size (76,8-98,5 %) predominate in the treated soil layer, the content of erosion-hazardous particles decreases In the surface layer by 2,90-18,13 %. The most qualitative soil cultivation was carried out by a working organ with elliptical, least - with a flat-topped ripper. To improve the performance it is advisable to give a curved shape to a flat-topped ripper made of plastic. There was a sticking of the front part of the counter of the organ. Plastic is not susceptible to sticking with moist soil and self-cleaning.
