Abstract

The research objective is to improve the quality of soil loosening using combined working bodies for surface moisture-retaining soil cultivation. The efficiency of accumulation and conservation of precipitation in the autumn-winter period depends on the method of post-harvest soil cultivation. One of them is the autumn surface water-retaining treatment, which makes it possible to increase the efficiency of the processes of accumulation and conservation of moisture due to the deeper loosening of the cultivated soil layer. During loosening and mulching, the top layer of the soil contributes to the accumulation and preservation of moisture not only in the upper but also in deeper soil horizons. However, the used tillage tools do not fully solve the problem of the high-quality performance of surface moisture-retaining soil cultivation. The article presents the results of studies of the degree of influence of geometric and technological parameters of the additional active cultivator on the quality of surface tillage. Based on the results of the research carried out, the technological process of performing the surface tillage operation has been improved and combined working bodies have been developed for its implementation.

Highlights

As an alternative to the main, deep tillage since autumn, cultivation is often used in recent years - the cultivation of the upper soil layer 5-12 cm and deeper without turning the layer
It is usually carried out after stubble cultivation; It is intended for weed control, loosening, and soil preparation for the season
With an increase in the distance from the stalk of the duckfoot to the strut of the loosening working body, an increase in the degree of incorporation of stubble residues into the surface layer is observed: at a distance of 100 mm, the degree of incorporation of stubble residues was 30 ... 36.7%, at a distance of 150 mm, the degree of incorporation was 38.1 ... 48, 2%, at a distance of 200 mm, the degree of embedding was 36 ... 47%, which indicates the active influence of the mutual arrangement of the working bodies on the quality and quantity of the created mulching layer (Figure 6)

Summary

Introduction

As an alternative to the main, deep tillage since autumn, cultivation is often used in recent years - the cultivation of the upper soil layer 5-12 cm and deeper without turning the layer. Paw cultivators are used for cutting weeds and loosening the soil by 5-12 cm Their working bodies are paws of various designs. Blade cultivators spray the soil much less than spring cultivators and cut the weeds deeper For deeper loosening of the soil, a chisel cultivator is used, which has several forms of working bodies (paws) attached to the frame in several rows and at different depths. There are various designs and patented inventions of various working bodies that combine a combination of various undercutting wings of swept arms and loosening chisel rippers This information on the means of mechanization for soil cultivation made it possible to identify ways for their improvement. To perform the autumn surface water-retaining tillage to improve the quality of the technological process, a combined working body was designed and manufactured
