The new antierosion and water saving technologies and tools for soil cultivation under the conditions of Uzbekistan
Аннотация
The purpose of the research is developing technology and technical tools for soil cultivation, which contributes water conservation and prevention of water erosion on sloping lands. The technology of soil cultivation on sloping lands exposed to water erosion, basic schemes and designs of a two-tier ripper and a plow for row-stepping plowing have been developed. The results of experimental and field tests of developed tools showed that they are significantly superior than the serial machines in terms of their main performance indicators, they help to preserve soil from water erosion, allow to improve the quality of soil cultivation, reduce energy costs, and increase the productivity of aggregates. Using two-level soil-ripper with inclined stands and a plow for stepped-stump plowing, allowed to reduce labor costs by 18.75 % and 14.4 %, fuel consumption by 19.12 % and 14.25 %, and increase labor productivity by 18.96 % and 14.28 %.
