Agrotechnical methods of weed control

Abstract

Introduction. The basis of crop production technology is a set of agrotechnical operations and organizational and technical measures related to preparing the soil for sowing and protecting crops from weeds. The use of agrotechnical methods of surface tillage allows simultaneously with the use of technical means without the use of chemical methods to perform weed control operations.

Object. The object of the study is an improved working organ of a steam cultivator.

Materials and methods. A working body of the KPS – 4 steam cultivator is proposed to combat weeds during surface tillage in steam fields, as well as in row spacing cultivated by a wide-row method of agricultural crops in irrigated and non-irrigated agriculture. By properly influencing the soil, we create optimal conditions for the development and growth of the root system of agricultural crops. As a result of loosening or compaction of the soil before sowing, effective fertility increases due to the optimal content of moisture, air and nutrients in it.

The purpose of our research is aimed at to increase the efficiency of surface tillage through the use of a self-cleaning working organ of a steam cultivator, which helps to reduce energy and economic costs in the cultivation of agricultural crops.

Results and conclusions. The created design of the working organ of the cultivator eliminates the overhang of plant residues of trimmed weeds on the rack of the pointed paw, providing a reduction in traction resistance, increasing productivity and quality of tillage by completely pruning weeds in the upper horizon of the soil, preventing the removal of moist soil to the treated surface.
